12+ Best Node.js Frameworks for Web App Development in 2022

Node.js is getting increasingly popular among developers, to the point where some developers call Node.js their primary choice for backend development. In this article, we review the 12 best Node.js web frameworks that we rate according to their popularity and unique toolkits for time and cost-efficiency.

Is Node.js a web framework?

So is Node.js a web framework? The most common way of referring to it is as a web framework. Still, Node.js is a JavaScript execution environment – a server-side platform for JavaScript code execution and portability. Instead, web frameworks focus on building features. A lot of developers have built Node.js web frameworks, such as Nest.js, Express.js, and other toolkits, for Node.js applications, providing a unique experience for software developers.

What are Node.js web frameworks?

Every web application technology offers different types of frameworks, all supporting a specific use case in the development lifecycle. Node.js web frameworks come in three types – Full-Stack Model-View-Controller (MVC), MVC, and REST API web frameworks.

Node.js web framework features

API of Node.js is asynchronous. You can use the Node.js server to move after a data request, rather than waiting for the API to return the information.
The code execution process of Node.js is faster compared to the reverse backend framework.
Node.js runs on a single-threaded model.
With Node.js web framework developers never face buffering issues because it transfers information by parts.
It is supported by Google’s Node.js runtime environment.

Through these features, it is clear to understand why developers more often choose Node.js for Backend development. Let’s take a closer look at each Node.js web framework.

What is Angular


Angular is a client-side open-source JavaScript-based front-end framework, which is used to build custom applications in HTML, CSS and Typescript. AngularJS was launched in 2009 by Misko Hevery and Adam Abrons as a project at Google.  It is a front-end JavaScript framework, which was developed to build web-based dynamic applications easier, due to its MVC (Model-View-Controller) feature. AngularJS is currently supported as a framework, although no longer being developed or updated.

Don’t confuse it with Angular (without JS) which is the term for Angular 2 and above (i.e. versions 2, 4, 5, 6, 7, 8, and now the latest version is 13) which was released in 2016. Angular 2, as it used to be known, demonstrated considerable differences from AngularJS, the main difference of which was its change in the template language.

One of the key features of Angular is that it uses TypeScript as a programming language. Alternatively, it is possible to create Angular applications using languages such as Dart or JavaScript. However, TypeScript is still the primary language. 

Angular has four main types of web app development:

PWAs (Progressive Web Apps)
UI animations
Web and mobile applications
Business web applications

Why use Angular

Angular is a quite popular framework for building web and mobile apps and can be the perfect framework for building large-scale, powerful and easy-to-serve web apps. So here is the list of reasons why you should use Angular:

Safety. Angular is a fairly trustworthy platform because it is supported by Google

Reduced development time. Angular relies on the current JavaScript virtual machine by transforming templates into code. Angular’s load time is also fast. 

Unit test friendly. Angular features two-way data binding of modules and components, which makes the code consistent and easy to understand for unit testing. Every unit of code is independently tested across the entire app building process, providing in-depth quality control.

Cross-platform. Angular-based PWAs can run on a variety of platforms, and the framework is widely used in native mobile apps. Previously, frontend developers used a cross-platform combo of Ionic with Angular. Nowadays, its most popular combo is with NativeScript.

Complex learning curve. Angular uses a much harder learning curve than other frameworks. To get started, you need to explore all aspects of the framework, such as RxJS (a reactive library for asynchronous development) and Typescript (used to increase maintainability and code support capabilities), not just basic JavaScript. 

Community. Angular has a great community and ecosystem which is actively supported. There is plenty of content on the framework like guides and videos, and lots of useful third-party tools as well.

With all the advantages of Angular, it is not a universal solution for absolutely every task, and that’s okay. Every technology is well suited to solve specific issues, and for some other tasks, other approaches will be more reasonable. It’s easy to use Angular to create a project, but it’s harder to understand if this solution is really good or if it’s worth using.

Who uses Angular

Let’s take a look at the list of cutting-edge companies that use Angular in their modern web application development pipeline:

Microsoft Xbox
Deutsche Bank
The Guardian

How to create your Angular application using the Flatlogic Platform

There are two ways to build your application on the Flatlogic Platform: one-page application only with the frontend or the CRUD application with frontend, backend, database.  

Creating the CRUD application with Flatlogic

1 Step. Choosing the Tech Stack

Firstly, you should set the name of your application and choose the stack: Frontend, Backend, and Database.

2 Step. Choosing the Starter Template

Next, you’re choosing the design of your web application.

3 Step. Schema Editor

In this step you will need to know which application you want to build, that is, CRM or E-commerce, also in this part you build a database schema i.e. tables and relationships between them.

If you are not familiar with database design and it is difficult for you to understand what tables are, we have prepared several ready-made example schemas of real-world apps that you can build your app upon modification:

E-commerce app;
Time tracking app;
Books store;
Chat (messaging) app;

Finally, you can make deployment of your application and in a few minutes, you will get a fully functional CMS for your Angular Application.

Creating a one-page application with Flatlogic 

You can create a frontend-only app with the Flatlogic Platform. This assumes you host the backend somewhere else or do not need it at all. To generate a one-page application you don’t need to enter anything in the terminal of your IDE, you just need to go to the page of creating an application on the Flatlogic website and make only 2 steps:

1 Step. Choosing the Tech Stack

In this step, you set the name of your application and choose the stack: Frontend as Angular, Backend as No-Backend.

2 Step. Choosing the Starter Template

In this step, you choose the design of the web app. Since this is a standard one-page application created using the CLI framework, it will have the design of a standard one-page Angular CLI application.

The final step is to deploy your app and in a few minutes, you will get a one-page Angular application, which you can further modify as you like.

4 Best Angular.JS Themes and Templates for 2022

The task of creating an admin panel for creating and editing content often arises in the web development process. The task, in general, is trivial, but it is not so easy to make a convenient admin panel.

A Couple Of Words About AngularJS

AngularJS is an MVC framework. Includes its own high-level ajax implementation, built-in unit, and e2e tests (Jasmine for unit testing, a special testing server is launched for end-to-end tests).

Angular.JS works according to the MVC scheme (Model-View-Controller – model-view-controller) – it divides the application into three separate parts that can be changed independently of each other.

Provides information (and responds to controller commands).

Responsible for displaying model data and monitoring changes.

Reacts to user input and notifies the model to update.

“AngularJS is not completely MVC; the controller will never have a direct reference to the view. This is great because it keeps the controller independent of the view, and also allows us to easily test the controller without needing to instantiate a DOM.”

Shyam Seshadri, AngularJS: Up and Running: Enhanced Productivity with Structured Web Apps

Most developers would choose the newest version of Angular to work with. This is a choice that no one will argue in the modern web development world. If you are new to Angular please note that AngularJS refers to the first version of the framework. Then there was a complete rethinking of technology. It was a great breakthrough, but it caused so much pain. The migration from one version to another took lots of time and effort. But in rare cases, you still need to use the old version – AngularJS. So this article is useful in these cases.

If you need admin templates with the newest version of Angular, you can check out Angular templates made by Flatlogic. Or we have several articles on Angular dashboards in our blog:

Top 10 Angular Material Admin Dashboard Templates

Top Angular Admin Templates

Despite all the pain that the new version caused, frontenders liked those changes. It made the framework much more flexible and scalable. Plus drastically changed technology in terms of speed and lightweight. And of course, as with every software update, it reduced drastically the number of bugs. And added some new:)

Check out Flatlogic Angular Templates!

Theme Support
E-Commerce Section
Fully Documented Codebase

This opened up huge perspectives for enterprise-like software. And to these days when we compare React and Angular, for example, we always point out this indisputable plus – it is perfect for gigantic enterprise apps.

To be fair we need to point out some minuses. This framework needs additional optimization to make the application load and work faster. Of course, it depends on the technology you compare Angular with. But in general, you will spend more time chasing the speed of your dream, though there are many ways to do this.

Another pretty obvious minus is too complicated directive API. I don’t mean that it is inconvenient, I’m just saying that very flexible. There is always the possibility that you will modify it the way you really shouldn’t. In simple terms: too much freedom. The easiest way to avoid the mistakes with API is to study carefully the documentation.

An Opinionated List of AngularJS Admin Dashboard Templates

So, let’s proceed to the review of admin panels made with AngularJS.

Sing App AngularJS

Image source: https://flatlogic.com/templates/sing-app-angularjs/demo


This admin template is created by Flatlogic Team using Angular.js and Bootstrap. Sing App Angular.js is made beautiful and stylish. The background color of the buttons changes after clicking them. Design connoisseurs will also notice the light glow from the navbar and the mesmerizing effect of smoothly opening tabs.

This dashboard template is multifunctional. It has charts, using them you are able to easily operate your data. From the dashboard, you get statistics, for instance, you see the number of visits. This information is available on the map and on the progress bars. In addition, you can find our other useful information, such as the user base growth, traffic values, market stats, and etc.

Developers have included forms, grid options, and a bunch of UI elements. For easy navigation, there’s a search field on the navbar, and a left sidebar that you can fix on the page or leave it collapsing. Sing App Angular.js is a multipage multifunctional responsive template that that takes its rightful place in this top.

Slant Admin

Image source: http://jaybabani.com/slant/site/


Slant Admin is positioned on the market as multiple admin themes in one. Let’s see why. But first, let’s pay attention to the technical stuffing. The basis of the template is AngularJS and Bootstrap. To build the project, developers connected Grunt and Bower. If you have heard nothing about Bower, this is a package manager that helps automatize the work, for example, you don’t have to download the files of frameworks or libraries manually.

Slant Admin is created developer-friendly. This template contains different blanks. Among its sections, we can find Dashboard, APPS, User Interface, Forms, Charts, etc. For UI content, there are many elements starting with Typography, Progress Bars, Icons, and ending with Image Cropper, Section Panels, Counter Tiles. There are also many pages, such as the Login page, Forgot password page, Error pages.

This is a responsive good-looking template. You can select the layout type for the sidebar. A nice finding is when you select the category from the left, the category name is duplicated on the navbar in the form of the tab.

This product contains 9 admin themes. They are the following: General Admin, Hospital Admin, University Admin Music Admin, CRM Admin, Freelance Admin, Blog Admin, E-commerce Admin, Social Media Admin. It means that Slant Admin can be a solution to the needs of different spheres of life. That’s why this product is called “multiple admin themes in one”.

Angular Material Dashboard

Image source: https://flatlogic.com/templates/angular-material-dashboard/demo


Another sample of coding with Angular.js framework is Angular Material Dashboard. Created with Angular Material design, the template’s interface looks self-contained and stylish. 

One of the main advantages that keep an eye is an informative multisector dashboard. From the dashboard, you will find out about the following:

the number of site visitors;
the number of warnings;
memory load;
Server Control Panel management;
usage statistics;
enabling or disabling of Autocomplete Input;
database performance;
TODO list. 

It’s very convenient to operate data due to integrated graphics for data visualization. In addition to the dashboard, there’s a table section and a profile page with the necessary fields. If you look through the demo, you’ll find the sharing option via connection to Twitter and GitHub. 

If you are considering creating an application like CMS, SAAS, project management tools, and if you looking for a smart template free of charge, then Angular Material Dashboard is the one that will help you achieve your goal. 

CoreUI for AngularJS

Image source: https://coreui.io/v1/demo/AngularJS_Demo/#!/dashboard


CoreUI is an admin template that is created with Angular.js and Bootstrap. This is a free template, in addition, free updates are provided. It’s an open-source project, however, everyone can donate to support it. 

The template doesn’t look like raw material, it looks like a well-designed ready-to-use dashboard. On the top of the screen, there’s a navbar; from the left side – a sidebar, and the main content in the center. What’s interesting is that the main content has its own navbar with the Home, Dashboard, and Settings buttons.

This project boasts an impressive list of UI elements. These elements are various and numerous. The list includes buttons (social buttons as a bonus), forms, tables, switches, icons (font awesome, flags), 4 types of charts; login, registration, error pages. CoreUI contains SCSS source files and 5 plugins, such as Angular Animate, Angular Breadcrumb, Angular Chart.js, Angular Loading Bar, and Chart.js. 

The color scheme of this admin dashboard is pleasant to the eye due to its dark sidebar theme and light theme of the main content. However, the color theme is represented with only one style, so you can’t switch to another scheme.

The team anticipated the expectations of more demanding users and released an extended version –  CoreUI PRO for AngularJS. This template contains UI kits for emailing and invoicing. Here you can apply more plugins (standard version plugins + Angular DateRangePicker, Angular DateRangePicker, Angular Translate, Angular UI Calendar, Angular UI Mask, Full Calendar, Toastr). What is more, in terms of the visual part, a PRO version can be switched to dark mode.

A Couple of Words About The Migration Possibilities

Some developers nowadays seek to migrate from AngularJS to the newest version of Angular. This journey can not be not easy, nor fast. Mainly because you will ask yourself a question, what if Google decide to change everything once again without backward compatibility. But in 2022 so far the transition to the new version is relatively easy.

Going back to the migration from AngularJS we must say that the sooner you start, the cheaper it would be. Every year Angular team makes lots of changes, so it is not always easy to keep up with those changes. 
But the Angular team developed two tools that are aimed to help you with that. 

The first.
ngMigration Assistant
This command-line tool recommends the best migration option by analyzing an app.

The second.
The most useful part of a forum in my opinion is a Migration Paths Overview. It suggests several options for you (the same as ngMigration Assistant):

Incremental migration,
Angular elements,
Code conversion,
Rewriting from scratch.

Functional Components vs. Class Components in React.js

The history of React.js components
Functional components in React
Class components in React.js
The difference between functional and class components
Bonus: Building an App with Flatlogic Platform

When you start to code with React you may get confused by some things in React, like JSX syntax or the difference between functional and class components. JSX is an interesting syntax extension to JavaScript that was developed to make the process of writing the UI elements more comfortable. The development with React doesn’t require using JSX, just like our article is not about it either. We are going to discuss Functional vs Class components. Let’s start.

The history of React.js components

We should jump into the history of React first to understand how React components evolved. React, created by Facebook software engineer Jordan Walke, is an open-source front-end JS library for building interactive user interfaces. The first release was in 2013, with 0.3.0 version. React has got further development and updated several times every year. The React team added more and more new features to the library to give developers more tools for coding. Among the most famous and loved features are the virtual DOM, one-way data-binding, JSX, reusable components, declarative programming, stable code, fast rendering of UI elements, great performance optimization opportunities. The current version at the time of writing this article is 17.0.1.

Along with all these benefits React offered it also gave developers two types of components they could use to create UI components. It can be supposed that both types of components provide the same opportunities for writing UI elements, and the choice depends only on the developer’s preferences. Well, it wasn’t true. The real situation was that class components were the only viable option to develop complex apps with React. The reason was that using class components you get a large number of capabilities, for example, state, while functional components didn’t provide such an option. However, the situation changed when React v.16.8 was released in 2019. A new version contained an update that was meant to take the development with functional components to the next level. React offered Hooks for functional components. The introduction of Hooks made it possible to write the entire complex application using only functions as React components. This is a deeply significant event that changed the way of React apps development. Keeping that in mind, we are going back to the present time and find out what is happening now and what functional and class components are.

Functional components in React

Functional components in React are just JavaScript functions like this:

function Foo(props) {
return <h1>Who is living young, wild, and free? – {props.name}</h1>;
const element = <Foo name=”Me!” />;
ReactDOM.render(element, document.getElementById(‘home’));

In our case, we render an element that represents the user-defined component called Foo. The element passes JSX attribute name=” Me” as a prop to our function component Foo, which returns a <h1>Who is living young, wild, and free? – Me!</h1> element as the result.

Props are inputs for both types of components. One of the main tasks of props is to pass information from component to component. It’s especially necessary if you want to build a dynamic user interface. However, there is one important rule that you shouldn’t forget: props are read-only. That means that all React components shouldn’t change their inputs and the same props must return the same result. Components that respect their props are called “pure”. That rule works both for class and function components. 

JSX is a special extension that allows us to place HTML elements right inside JavaScript code without using additional methods like createElement(). All your HTML tags will be converted into React elements after compilation. JSX may be convenient, however, it is an optional instrument for development. To see how the same blocks of code look like with/without using JSX try the online Babel compiler

Another way of writing function components is by using an arrow function.

An example of an arrow function:

const App = () => { //that is an arrow function
const greeting = ‘Hello Function Component!’;

return <Headline value={greeting} />;

const Headline = ({ value }) =>

export default App;

Arrow functions have some benefits: 

The code written with arrow functions looks compact. Functions are easier to write and read. One of the reasons is an implicit return by simply omitting the curly braces (see video with an example).
Arrow syntax doesn’t contain its context and automatically bind this to the surrounding code’s context 

But since arrow functions give one more way to write code (along with standard functions and classes) you need to set rules when we use any of them. As an example you can stick to the following rules:

If you work with global scope and Object.prototype properties use function.
If you work with object constructors use class.
If you face any other situation use arrow function.

The examples above are called stateless function components because they just take props as an argument and return a react element. They don’t manage state and don’t have a lifecycle, while class components do. However, you can use Hooks with them that allow you to work with state and lifecycle and add even more features. We will speak about that in the comparison below.

Class components in React.js

Let’s start with an example:

class Foo extends React.Component {
render() {
return <h1>Who is living young, wild, and free? – {this.props.name}</h1>;

It is a regular ES6 class that extends the component class from the react library. To return HTML you have to use render() method in it. 

Class components work fine with props as well as functional components do. To pass the props to a component you can use a syntax similar to HTML attributes. In our sample case we need to replace props.name with this.props.name in the render() body to use props. 

Additional benefits class components offer by default are state and lifecycle. That is why class components are also known as “stateful” components. 

The state of a component is an observable object that holds some information and controls the behavior of the component. The difference between props and state is that props don’t change over time during the lifetime of a component. The state holds the data that can be changed over time and changes the component rendering as a result.

The state of a component is supposed to have the initial this.state that can be assigned with a class constructor. The class constructor is a special JavaScript method that allows to bind event handlers to the component or to initialize the local state of the component. 

If you don’t need to handle any of both cases above the implementation of a constructor is unnecessary. Example of a constructor:

constructor(props) {
this.state = {};

Constructor() function inside a React component requires super(props) before any other statement. Super(props) is a reference to parents constructor() functionthat React.Component base class has. When we define a new constructor() inside a class component, we replace the base constructor() function. However, it has some code inside of it we still need. So to get access to that code we call super(props) – that is why we have to add super(props) every time we define a constructor() inside a class component. The constructor() is called before the React component is mounted. To use state in a class component we must define the initial state of it in the constructor. Instead of calling setState(), we need to assign the initial state with this.state command in the constructor. It’s the only case when we are allowed to change the state directly by assigning its value, otherwise use setState() instead. Constructor() has other rules you should be aware of, you can read about them on the link

Differentiating Functional vs Class components

1.State and lifecycle

Well, the standard answer to the question about the difference between functional and class components was that class components provide developers with such features as setState() and lifecycle methods componentDidMount(), componentWillUnmoun(), etc., while functional components don’t. That was true because functional components are plain JavaScript functions that accept props and return React elements, while class components are JavaScript classes that extend React.Component which has a render method. Both state and lifecycle methods come from React.Component, so they were available only for class components. The widespread advice was something like that: “Go with functional if your component doesn’t do much more than take in some props and render”. You had no options on how to build complex UI and class components dominated in React development for a while.

However, that has changed with the introduction of Hooks. To replace setState method to work with the state in class components React offers useState Hook.

To work with components lifecycle classes have such methods like componentDidMount, componentWillUnmount, componentWillUpdate, componentDidUpdate, shouldComponentUpdate. Functional components have got a tool to work with the same methods using only one Hook useEffect. You can think of useEffect Hook as componentDidMount, componentDidUpdate, and componentWillUnmount combined. 

Standard class methods work well but do look not very elegant. Functional components offer an elegant and simple decision: instead of using multiple lifecycle methods, we can replace them with one Hook useEffect. What React developers write about Hooks:

“Our goal is for Hooks to cover all use cases for classes as soon as possible. There are no Hook equivalents to the uncommon getSnapshotBeforeUpdate, getDerivedStateFromError and componentDidCatch lifecycles yet, but we plan to add them soon. It is an early time for Hooks, and some third-party libraries might not be compatible with Hooks at the moment.”

an official React documentation

So Hooks are more addition to functional components rather than a replacement of class components.

2. Syntax

The obvious difference is the syntax. Let’s examine several examples.

How we declare components.

Functional components are JavaScript functions:

function FunctionalComponent() {
return <h1>Hello, world</h1>;

Class components are classes that extend React.Component:

class ClassComponent extends React.Component {
render() {
return <h1>Hello, world</h1>;

To return our h1 we need the render() method inside a class component. 

The way we pass props.

Let’s say we have props with the name “First”.

<Component name = “First” />

Working with functional components, we pass the props as an argument of our function using the construction “props.name”. 

function FunctionalComponent(props) {
return <h1>Hello, {props.name}</h1>;

With class components, we need to add this. to refer to props.

class ClassComponent extends React.Component {
render() {
return <h1>Hello, {this.props.name}</h1>;

Handling state.

To handle state functional components in React offer useState()Hook. We assign the initial state of count equal to 0 and set the method setCount() that increases it by one every time we click a button. The component returns the number of times we clicked the button and the button itself. The initial state is used only during the first render. The type of argument can be a number, string, object, or null. To learn more about that useState() Hook see the official documentation.  

const FunctionalComponent = () => {
const [count, setCount] = React.useState(0);
return (
<p>count: {count}</p>
<button onClick={() => setCount(count + 1)}>Click</button>

Class components work a bit differently. They use setState() function, require a constructor, and this keyword. 

class ClassComponent extends React.Component {
constructor(props) {
this.state = {
count: 0

render() {
return (
<p>count: {this.state.count} times</p>
<button onClick={() => this.setState({ count: this.state.count + 1 })}>

The underlying logic is similar to the logic in functional components. In constructor() we declare a state object, state key “count” and the initial value equal to 0. In render() method we use setState() function to update the value of our count using this.state.count and the app renders the number of times the button was clicked and displays the button itself. The result is the same, but the same functionality requires more lines of code for class components. However, it doesn’t mean that the code written with class components will be more cumbersome than the code made with functional components, but the code definitely will be bigger.

Lifecycle methods.

With version 16.8 React allows working with lifecycle methods of components. That means that developers have better control over functional components and can manipulate their life phases (initialization or setting the initial state, mount, update, unmount). The initialization is explained in the paragraph above, let’s look at the next stage.


The useEffect Hook for functional components:

const FunctionalComponent = () => {
React.useEffect(() => {
}, []);
return <h1>Hello, World</h1>;

The componentDidMount method for class components:

class ClassComponent extends React.Component {
componentDidMount() {

render() {
return <h1>Hello, World</h1>;

The useEffect Hook possesses two parameters: the first is the “effect” itself that is going to be called once after every render of the component. The second parameter is an array of observable state or states (or so-called a dependency list). useEffect Hook only runs if one of these states changes. Leaving the second parameter empty useEffect Hooks runs once after render.


The useEffect Hook for functional components:

function BooksList () {
const [books, updateBooks] = React.useState([]);
const [counter, updateCounter] = React.useState(0);

React.useEffect(function effectFunction() {
if (books) {
updateBooks([…books, { name: ‘A new Book’, id: ‘…’}]);
}, [counter]);

const incrementCounter = () => {
updateCounter(counter + 1);


The componentDidUpdate method for class components:

componentDidUpdate(prevProps) {
// Typical usage (don’t forget to compare props):
if (this.props.userID !== prevProps.userID) {

As we have mentioned the second parameter in the useEffect hook is an array of observable states, once a counter changes it triggers the effectFunction hook.


The useEffect Hook for functional components (yes, again):

const FunctionalComponent = () => {
React.useEffect(() => {
return () => {
}, []);
return <h1>Bye, World</h1>;

The componentDidUnmount method for class components:

class ClassComponent extends React.Component {
componentDidMount() {

render() {
return <h1>Hello, World</h1>;

3. Hoisting works only for functional components

Hoisting is a concept that appeared in ECMAScript® 2015 Language Specification. According to that concept, JavaScript moves variable and function declarations to the top that allows you to access a variable or a function first and only then declare it. Actually, JS doesn’t move the code, it puts declarations in memory during the compile phase that allows calling a function before you declare it. That is not true to classes, trying to get access to a class before the declaration throws a ReferenceError exception. 

An example of the code where we call function before its declaration: 

function catName(name) {
console.log(“My cat’s name is ” + name);
// The result of the code above is: “My cat’s name is Tiger”

Even though we call the function before we write it, the code works great. The following code with class declaration will throw an error: 

const p = new MyName(); // ReferenceError
class MyName {}

That is not all. JavaScript only hoists declarations, not initialization. If we declare a variable and call it before the initialization it returns undefined. See example: 

console.log(myName); // Returns undefined, as only declaration was hoisted
var myName; // Declaration
myName = “John”; // Initialization

Initializations with keywords let and const are also hoisted, but not initialized. That means that your app is aware of the variable existence. However, it can’t use it until variable initialization. The example below will throw a ReferenceError:

myName = “John”;
let myName;

That example will not run at all:

myName = “John”;
const myName;

Why does it matter? Let’s get back to React and create a simple React app in index.js file with one component in a separate file Component.js:

import React from ‘react’;
import {render} from ‘react-dom’;
import App from ‘.Component’;render(

And the component itself:

const Component = () => {
return (
<div>Hello, React</div>
export default Component;

The app renders a text: “Hello, React”. Since the component is small, there is a sense not to separate it and merge it into index.js file like this:

import React from ‘react’;
import {render} from ‘react-dom’;
const Component = () => {
return (
<div>Hello, React</div>

And we get an undefined error because we try to render a component that was declared with an arrow function before we initialize it.To repair the code just re-order the declaration and put it before calling render().

4. The way they capture values (props)

One interesting experiment (the original article with full analysis can be found here) that took place on the Internet is the following React app.

It’s a simple app that simulates a social network request to follow someone. The app displays a drop-down list with three profiles to follow, static greetings text, and two buttons that call the confirmation alert to start following a chosen person. The confirmation alert appears 3 seconds later after you clicked the button. The delay is set with setTimeout() method. 

The list of the experiment is the following: 

Choose a profile to follow 
Click a follow button with “function” text in brackets near it
Change a profile to follow in the drop-down list before the confirmation alert appears 
Check the name in the confirmation alert 
Repeat the same four steps above for the follow button with “class” text in brackets

In the first case with the functional button switching the name doesn’t affect the confirmation alert. With the class button switching the name changes the alert message, even though you clicked to follow Dan but switched to Sophie, the alert message will be “Followed Sophie”. The correct behavior is the first, of course. No one likes to follow a wrong profile on social media.  

The reason for such a behavior lies in the essence of functional and class components. Let’s examine these lines of code:

class ProfilePage extends React.Component {
showMessage = () => {
alert(‘Followed ‘ + this.props.user); };

function ProfilePage(props) {
const showMessage = () => {
alert(‘Followed ‘ + props.user);

As we have said props are read-only, they are immutable. So once you pass the props to a functional component ProfilePage(props), the only remaining task for React is to render it after the time is up. 

On the other hand, this is mutable. And it’s okay because it allows us to use states and lifecycle methods correctly. So if we pass other props while the alert message doesn’t appear, this.props.name. changes and showMessage method displays the last version of props. Our showMessage method is not tied to any particular render and that may become a problem. 

There are several potential solutions that actually work. One of them is to catch props at the time of render like this:

class ProfilePage extends React.Component {
render() {
// Capture the props!
const props = this.props;
// Note: we are *inside render*.
// These aren’t class methods.
const showMessage = () => {
alert(‘Followed ‘ + props.user); };

const handleClick = () => {
setTimeout(showMessage, 3000);

return <button onClick={handleClick}>Follow</button>;

So we stuck our certain props to a particular render().

5. Running tests 

There are two most popular instruments for running tests: Enzyme and Jest. Enzyme is a JavaScript testing utility for React that allows testing React components’ display. Jest is a JavaScript testing framework for writing tests, in other words, for creating, running, and structuring tests. 

These two instruments do a great job on both types of components. There are some specificities in running tests for functional components, like the fact, that state hooks are internal to the component and can’t be tested by calling them. However, instruments and methods are similar. 

6. Performance difference 

There is an opinion that functional components show a greater performance compared to class components. The point is that the React functional element is a simple object with 2 properties: type(string) and props(object). To render such a component React needs to call the function and pass props – that is all. 

Class components are more complex: they are instances of React.Component with the constructor in it and complicated system of methods for manipulating state and lifecycle. 

Theoretically, calling a function should take less time than creating an instance of a class. Well, one developer held a test: he rendered 10000 elements of stateless components and class components. You can see the result here. As we see from the 3 experiments there is no difference in render time between rendering class and functional components.

To sum up everything above: 

Сlass components were the only option to add states to components and manipulate lifecycle. However, it has changed since the introduction of Hooks, which gave the same opportunities to functional components as classes had. 
The major difference is the syntax. It relates to the way we declare components, pass props, handling states, manage lifecycle. 

Function components capture the props and state by default. It is not a bug, but a feature of functional components.

Functional components require less code to write an equal component. However, that doesn’t mean that functional components more readable and convenient to use. If a developer is used to work with object-oriented programming, he finds using class components much more comfortable. Those who are used to functional programming like functional components more than class components. 
There are two most popular tools to test functional and class components: Enzyme and Jest. They work great for both types of components. 
There is no big difference in render time between class and functional components. 

Today you can build a whole app using only functional components. It was impossible till 2019. That became possible thanks to Hooks. Does Hooks replace class components in the coming years? We don’t think so, because there are still some features that functional components can’t reproduce. And there will always be developers, who are used to working with objects rather than with functions. However, we await the growth in functional component popularity and an increase in the number of features for Hooks. And it’s likely that the functionality Hooks will provide goes beyond class components possibilities. 

Bonus: Building an App with Flatlogic Platform

Understanding Functional and Class components is an important stepping stone in React development. Crafting Apps by hand requires a thorough understanding of all the intricacies of the library. However, there’s a quicker way for those who aren’t technically adept or lack time to write the whole thing from the ground up. Some people need a unique App with functions not seen elsewhere, but most apps are different combinations of the same parts and features. We used that insight when developing the Flatlogic Platform.

Flatlogic Platform is a constructor-style tool for combining pre-built parts into brand-new applications. It requires a few steps from you. Keep reading to know what those are!

#1: Name the Project

This step is what it sounds like. The only valuable advice we can think of is to pick a name that is easy enough to associate with the project.

#2: Choose stack

Next up, choose the technologies your App’s parts will run on. Those are underlying technologies for back-end, front-end, and database. In this example, we’re picking a combination of React, Node.js, and MySQL. But all other combinations are perfectly compatible, too.

#3: Choose Design

You’ll have several design schemes to choose from. Some are transparent and light, others with a heavier feel. Pick the one you like, this part is purely aesthetical.

#4: Create the schema

The schema is the structure of a database. Names of fields, types of data, the way the App processes said data… Every aspect that defines how the database works is a part of the schema. It might be tricky at first, but you’ll get the hang of it. A thorough review of what your App is supposed to do will be helpful. If you’re short on time or unsure, pick one of the pre-built schemas. One of them is bound to suit your needs.

#5: Review and generate

The heavy decision-making is over. It’s time to check if every choice you’ve made is the way you want it to be and (assuming everything’s fine) hit “Finish”.

The compilation takes a couple of minutes on most devices. Upon completion, the Platform will offer you your very own App. Hit “Deploy”, host it locally in one click or push it to GitHub for further use or adjustment.

Flatlogic Platform helps create simple yet functional and smooth Apps for commercial and administrative purposes, make sure you give it a try! Happy developing and see you in the next articles!

What is Next.js and Top Next.js Templates

What is Next.js
Why use Next.js
What can you build with Next.js and when to use Next.js
Pros and Cons of Next.js
Top Next.js templates

Modern web application development involves rapid testing of hypotheses, building MVPs, and testing them, which requires appropriate tools. Accordingly, now we have a variety of different tools and frameworks for building web applications.

Another requirement that has become widespread in the development of web applications is the speed of work and the speed of loading pages. That creates a perfect opportunity for companies that decided to trust modern technologies, like React.js, or have chosen the way of the Jamstack approach.

In the modern world of web development, what you just can’t find, for example, frameworks for frameworks or the so-called meta frameworks. In this article, we will talk about just such a meta-framework – next js, which is built on without React.

Most of the reason why companies and developers choose next js is that it is a full-stack framework (as in, it handles both the frontend and backend of your application) and offers support for a variety of rendering methods — even mixing and matching those methods as needed.

We will find out what next js is, why to use it, its disadvantages and advantages, and for the first time, we will write about the best templates for next js.

What is Next.js

Next.js is a JavaScript framework that enables you to build superfast and extremely user-friendly static websites, as well as web applications using React. Next.js allows the building of hybrid applications that contain both server-rendered and statically generated pages.

Why use Next.js

Let’s list the main features that make next.js so popular and why many developers consider it the best library right now.

Different render options out-of-the-box

One of the most important, if not the most important, next.js feature is the different types of rendering that you can do in your application.

By default, next js is using Server-Side Rendering (SSR) and at the same time is can be also a great Static Site Generator (SSG).

Next.js provides an out-of-the-box solution for server-side rendering (SSR) of React components. With Next.js, developers can render the JavaScript code on the server and send simple indexable HTML to the user. Before that, this could also be done manually, but it required a lot of work with caching server load, on-demand content, or the architecture of the application itself.

Incremental server-side rendering

Next.js allows you to create or update static pages after the site has been built. Incremental static site regeneration will allow developers and editors to use the static site generation mechanisms applied to individual pages, without having to rebuild the entire site. The use of ISR allows you to maintain the strengths of SSG on a project scale of millions of pages.

Improved Search Engine Optimization

Next.js allows you to build web applications with full functionality and interactivity of SPA without losing the SEO aspect but even adding. With this, developers do not even need to think about how to make an SEO-optimized project, because it will be like this by default.

Enhanced performance

Next.js frees the browser from loading and working with all the Javascript code at once, thus increasing such a metric as a time to first draw (TTFD). It measures the amount of time needed for the user to see the very first content on their screen and should ideally be below 1 second. This factor will improve both User Experience and SEO.

Part of the React ecosystem

Next.js is part of a large React ecosystem, with all its benefits in the form of several best practitioners, community help, useful libraries, and already solved corner cases. Next.js was also developed specifically for React, so it will be easy for you to embed this framework into your existing application.

Great User Experience

Thanks to Next.js you can build a fully customized user experience. Let’s see what it means.

Fully customizable – you can customize the look of your application anyhow you need or want. It also allows you to make changes without any limitations.
Adaptability and responsiveness – sites and applications built on Next.js are responsive out of the box and look good on mobile devices.
Speed – Next.js websites can be super-fast because they are static so visitors will be more than satisfied with the performance.
Data security – in the case of Next.js, the data on the site is not directly linked to the site, so it is more difficult for an attacker to get it.

All of these things mentioned above make the user experience as great as it can be.

Developer Experience

It is worth stopping a little here and noting how much the next values development experience. This thread stretches from the very origins of the framework – ease of development and implementation, clear documentation, examples, easy transition to new versions.

Great work with images

Images take up a significant part of the site not only in terms of page size but also in terms of page weight. Since version 10, next js can automatically compress all images, a little later the ability to compress them with any library you like was added. Also, the <picture /> component automatically adds width and height attributes. However, even optimized images can spoil the metrics if they are on the first screen. Therefore, next js has a built-in placeholder option for images.

Easy to learn for React Developers

If you’ve written any React application at all, you’d find yourself very familiar with Next.js.

Out of the box support for Sass Modules and TypeScript

Next.js has great support for TypeScript out of the box. Recently they also added module-based support for Sass as well. This means that your styles can now be written in Sass, local to your modules, with caching and revalidation – all managed by Next.js internally.

File-system routing

You don’t need to use any third-party libraries to handle and configure routing.

Persistent Caching for Page Bundles

Next.js also supports persistent caches for pages that are not changed.

Internationalized Routing

Next.js has built-in support for internationalized (i18n) routing. It is the feature that automatically sets the language for the user.

Code Splitting

Next.js has Code splitting feature out of the box. It simply splits the code into separate bundles to make the load faster.

What can you build with Next.js and when to use Next.js

With Next.js you can build several apps and websites like:


Admin panels;
MVP (Minimum Viable Product);
Jamstack websites;
Web Portals;
Single web pages;
Static websites;
SaaS products;
eCommerce and retail websites;
Complex and demanding web applications;
Interactive user interfaces;

What projects are most suitable for Next.js? 

When creating a landing page

Next.js is great for creating landing pages and other marketing tasks.

When SEO Matters

When building e-commerce sites, search engine optimization is more important than ever. With server-side rendering, Next js excels in this regard as well.

When creating websites

Server-side rendering of the application removes the need for clients to render on their devices. For users of slower devices, this can result in faster boot times.

Pros and Cons of Next.js


Steep learning curve because of good and short documentation;
Built-in support for TypeScript;
In Next js, the developer can choose which page to render on the server and which to render during the build. This is the most flexible and optimal approach possible in principle;
Big community;
Great for SEO;
Zero Config – next js allows you to focus on the business logic of your application instead of the application logic. And to help you, it provides automatic compilation and bundling; In other words, Next is optimized for production right from the start;
Fast Refresh – fast, live-editing experience;
Built-in CSS support – possibility to import CSS files from a JavaScript file;
Next js Provides Routing – NextJS provides a quick and easy way to create APIs in applications. If your application uses third-party APIs, then you often need your API for proxy requests and token storage. Next.js routing is perfect for this.


Cost of development – since Next.js does not provide many built-in front pages, you have to create your front-end, which will require changes from time to time. It means that you will have to pay a developer to get the job done;
Bad integration with state management libraries – so if you need a state manager in your app, you have to add Redux, MobX, or something else;
The low number of easy to use plugins plug-ins;
Next js – opinionated framework;
There is only one way to work with routes in NextJS, and you cannot customize it for yourself. Next.js is limited to its file-based route, and dynamic routes are only possible when using a NodeJS server.

In this article, we examined what next js is, its advantages and disadvantages, and where it is best used. Next js has a rich history, large community, stable growth, and development. The framework has both obvious advantages in the form of different types of rendering, and disadvantages – it is very opinionated.

We found out that Next js is reasonable to use for building small applications of several pages, or for medium-sized applications, with a relatively simple architecture, which seems to be possible to think through completely before you start writing it. A large project will inevitably face problems and bugs that it is not clear how to fix, and in addition, there is a risk that you will have to constantly rewrite the application so that it works normally because the practices set out in the documentation that you start to use will be changed to some new approach.

And in order to speed up development on Next js, you can refer to the templates that we presented in this collection.
