How to choose the right javascript charting library? Top javascript charting libraries Conclusion About Flatlogic

JavaScript Charting Libraries: Introduction

In today’s world, people are struggling more and more with the problem of scattered attention. So it is becoming more and more important to present information in a structured, interesting, and well-designed way, especially if you have a complex business application. Presenting huge chunks of data in a standard spreadsheet to analyze or to study is as inconvenient as it can get. Creating different charts and JavaScript charting in particular is a big issue that we will consider.

Javascript charts are an essential part of a web application for presenting data. It means JavaScript charting libraries are inevitable. The way the human brain itself is programmed is that it understands visual data much better than anything else. Well visualized data creates much more influence than the data being presented as it is, no matter how well it is explained.

Companies build strategies around the charts, numbers, and tables they’re presented with, and often use them to choose whether to pursue business opportunities. It is very important to choose the right tool to build a workaround.

But how do you choose the tool that will fit your requirements in the javascript technology zoo? How to choose the right graphics for your data? Should it be paid or free? Build your own solution or take a ready-made tool?

We will try to cover all these questions in this guide. First, we will talk about how to choose the right javascript charting library. Then we will define the criteria for evaluating the tools, and finally, compare the most popular javascript charts on the market.

How to choose the right javascript charting library?

When you approach the choice of the chart js library, everything is highly individual and depends on many criteria. Therefore, in this section, we will consider things you should pay attention to while choosing the tools for drawing charts.

There are quite a few javascript charting libraries around now, but which are the best to use? This can depend on many factors like business needs, types of data, the purpose of the chart itself and many more.

A nice interface and copy/paste code are all well and good if we need something generic to our needs. But frankly speaking, most of the time we actually need something tailored to our use case. Even more than that  –  we need a reliable charting library we could build upon.

There are several factors to consider here:

What kind of charts does the company want to build? Pie charts, maps, lines, bars? How large is the dataset? Is the app going to be used for Web, mobile, or both? SVG or Canvas base? Libraries based on SVG are usually better for smaller to medium datasets, as each element is a unique node and exists in the DOM tree. On the other side, Canvas is really fast. What is the browser support for a given library? Check your browser market share to figure this out. Which JavaScript framework do you use? What kind of customization of the look and feel do you need?

Note that in some cases you may not need a data visualization library at all. Sometimes it’s better just to write one from scratch using vanilla JavaScript.

Here is an example of a decision diagram that I have found on the internet. 

Top JavaScript Charting Libraries

In this article, each JavaScript charting library will be compared with some key factors including chart types, commercial or free, and open-source status. These beautiful libraries have been analyzed thoroughly with hands-on experience to maximize the very best comparison.

Highcharts

License: Free for non-commercial, paid for commercial
Price: Free to $7060
Main dependencies: No dependencies
Web-site: https://www.highcharts.com/

HighCharts a modern javascript charting library based on SVG technology. It doesn’t require any plugin. The integration with all of the major web frameworks is very simple.

In all of its simplicity, Highcharts is also very much compatible with old browsers, so you can pick it if you don’t need to represent data using advanced charting styles.

Notable Features:

Optimized for both responsive design and touch devices; Capable of working with Big Data; On-hover tooltips rendering is super-quick; Ability to annotate graphs; Data can be loaded to charts directly from a CSV file.

Highcharts allows you to configure the theme separately from the data. This allows you to have a common theme for your brand to apply across all the charts on your website. 

Highcharts is extensively documented and has most use cases covered. 

HighCharts is used by some major companies across the world, including Facebook, IBM, MasterCard, and StackOverflow. It’s probably the most advanced library out there regarding types of charts available, but of course, comes at a cost for commercial use. If the pricing is not a stumble, Highcharts is an excellent choice.

Chartist-js

License: Open-source
Price: Free
Main dependencies: No dependencies
Web-site: http://gionkunz.github.io/chartist-js/

Chartist is a very modern, SVG based library. Its biggest feature is the SVG animations in the charts produced with this library.

It has a solid technology base and is very easy to implement. Within minutes you can make an incredibly impressive chart that interacts easily with any backend data source. Chartist is really easy to configure, as well as easy to customize with Sass.

This library has only 8 base chart types which can be used to improvise over a few more different types. Each is fully responsive but doesn’t have a great transitional effect as others.

Features:

Filtering by labels; Click on a legend to show and hide data on the chart; Non-numeric Y-Axis, have labels instead; Easy customization with interpolation of line charts.

The Chart.js visualization library is completely open-sourced with the MIT License and available to modify, distribute, and use. Source files are available to ‘fork’ on GitHub too.

Chart.js offers a vast documentation base including precise instructions on installing the library. The library can be quickly installed with Bower, NPM, jsDelivr, and can even be linked up from CDNJS. Besides, you can download the source files directly from the GitHub Repo.

Chartist is a very powerful charting library, but it requires more work on the developer’s end to get things to look right.

The charts and graph types available have a professional look and feel. Creating a chart is just a matter of loading in your information and customizing the layout, axes, notes, and legend.

NVD3

License: Open-source
Price: Free, paid for enterprise
Main dependencies: D3.js
Web-site: http://nvd3.org/

NVD3 is also on the list of the most popular libraries. Built upon D3.js like the others above, it does have a solid technical base.

The performance is relatively good, and it does have basic animations to inject some visual stimulation in an otherwise fairly plain interface. Data can be pumped directly from .json files, meaning NVD3 is very easy to integrate with existing data API solutions.

When compared to other libraries on this list, it looks rather small with many charts not available, but most of the general graph-types are present.

This visualization library is completely open-sourced with the Apache 2.0 License.

Fusion Charts

The watermarked version is free. To get rid of the branding, as well as to use AnyChart for any commercial purpose, it’s necessary to buy a license (starts from $49).

Recharts

License: MIT
Price: Free
Main dependencies: d3.js
Web-site: http://recharts.org/en-US/

 

Recharts provides a set of modular javascript charting components and does a great job by letting you mix those components together to easily build things like a composed line and bar chart.

It is the most popular library to date. It has more than 11k stars on Github, but there is a huge number (600 to date) of open issues as well.

The documentation is quite extensive but lacks details in some parts. You can find a bunch of examples at Recharts website, which could be a good starting point for building your own charts.

What’s a bit troubling is the high number of unsolved issues on GitHub. These issues may not be critical, but creators don’t seem to drop by to answer them too often. So if you get stuck, be prepared to dig deep into the library.

Wrapping Up JavaScript Charting Libraries

With charting being something we all need to implement so often now, it’s no great surprise that there are many open-source charting libraries available for us to choose from.

All of the javascript charting libraries we mentioned above have very good browser compatibility and fallbacks available for people using legacy browsers. The libraries built upon D3 have a solid base, but personally, I find them a little bit underwhelming from an aesthetic aspect.

Javascript chart Libraries like FusionCharts, GoogleCharts, Dygraphs, or one of the D3 derivatives may work best for corporations with large data sets, or small businesses that rely heavily on data analysis. Both commercial offerings, Highcharts, and FusionCharts are mature libraries that can fit most use cases very well. Both of them have varying degrees of support for large datasets (>100k data points) and support a large variety of charts. If there is a specific type of chart you need to render, the choice might narrow down to only one of them.

If you just need something small and quick, Morris.js or Chart.js might work better for you. For graphs and networks, Cytoscape or Sigma.js is probably the way to go.

If you want to stick to a free and open-source library, use Chart.js. It is extremely simple to use for common use cases. If you need a little more control over rendering, then you could look into Chartist.

To select the best JS chart solution for your unique needs, I recommend testing your own data against a couple of the libraries listed above to ensure a perfect fit for your current and future projects.

P.S. We have prepared a table to show the popularity of libraries by downloading them through npm. We see that the most popular are d3, chart.js, and Highcharts.

Honorable Mention: Victory

 

Victory by Formidable Labs caught our attention after the article originally came out. Normally, charts, templates, libraries, and other tools fall into a specific point of the beginner-pro spectrum. Beginner-friendly entries aren’t very customizable and professional tools aren’t too simple. Occasionally, however, there’s a solution that covers more ground on the spectrum, and each of those is a real treat. Victory is one such example.

Victory is customizable in just about every way an average user would ever think of. The default design is simple and concise but you can change it to something more picturesque if that’s what you’re after.

About JavaScript Calendar Plugins

Calendars are an important part of our lives. In today’s world, people mostly use the web or mobile calendars. They can be found everywhere, including various software: booking apps, travel software, project management, admin panels, etc. Our company often integrates JavaScript calendar plugins into admin templates (you can look through our angular themes).

Users may need JS calendars on websites for several reasons. The user may need to pick a date from the calendar to fill up a form or provide a date while delivering any information.

Undoubtedly, this component can be called critical for business applications. Just imagine how much your business can suffer due to a badly tuned and developed calendar. Thus, this component should be given special attention and meticulousness in development.

In this article, we will look at the criteria for a good javascript calendar in web applications. Also, we will show you the best javascript calendar libraries and different frameworks for building your own solutions based on them.

Qualities of good javascript calendar plugins for web applications

We have picked the criteria for good javascript calendar plugins from our previous article on date-pickers. Obviously, we can adapt these to calendar plugins. We divided our evaluation criteria into 4 blocks.

Documentation. It is vital for whatever you’re using to be well-documented in order to learn how to build or reconstruct it. The product with no or lacking documentation does not have a right to exist.

Customization. A great library should come with options that can be updated to add or remove certain functionality. This especially applies to open-source software.

Compatibility. Who wants to visit a site with a datepicker that only works in recent versions of Chrome and Webkit browsers? Many business apps still work in legacy browsers.

User Experience. Ask yourself whether the plugin will be convenient for the needs of your user? Does it fit your product style? The looks and quality of the docs are not that important compared to how the library will actually deal with your task.

Price. And finally please keep a track of your software budget and usage.

Top JavaScript Calendar Plugins

We have included various calendar libraries based on React, Angular, Vue, Bootstrap or jQuery. Some of them are more developed, some are easier to customize. We hope this catalog will help you with your work. Let’s dive into our collection of the best JavaScript calendar plugins!

If you Command (Mac) or Control (PC) click the Fork button, it will open the newly forked Pen in a new tab in your browser. That’s new behavior. Before, it would open the fork in the same tab, no matter how you click. That was unfortunate, as Cassie called out:

Why didn’t it work like this before? Well, that’s what Shaw and I get into in this podcast. It’s a smidge complicated. The root of it is that that Fork button isn’t a hyperlink. It’s a button handled by JavaScript because of the nature of how it works (a fork might have data that only the client knows about: unsaved code changes). But Shaw found a way to make it work anyway, by essentially passing the metaKey information through all the forking process until that moment we had an opportunity to open that new tab.

Notion is an incredible organizational tool. Individuals can get a ton out of it, but I find the most benefit in making it a home base for teams. It can replace so many separate tools (documents, meeting notes, todos, kanbans, calendars, etc) that it really becomes the hub of doing work, and everything stays far more organized than disparate tools ever could.

React 18 is now available on npm!

In our last post, we shared step-by-step instructions for upgrading your app to React 18. In this post, we’ll give an overview of what’s new in React 18, and what it means for the future.

Our latest major version includes out-of-the-box improvements like automatic batching, new APIs like startTransition, and streaming server-side rendering with support for Suspense.

Many of the features in React 18 are built on top of our new concurrent renderer, a behind-the-scenes change that unlocks powerful new capabilities. Concurrent React is opt-in — it’s only enabled when you use a concurrent feature — but we think it will have a big impact on the way people build applications.

We’ve spent years researching and developing support for concurrency in React, and we’ve taken extra care to provide a gradual adoption path for existing users. Last summer, we formed the React 18 Working Group to gather feedback from experts in the community and ensure a smooth upgrade experience for the entire React ecosystem.

In case you missed it, we shared a lot of this vision at React Conf 2021:

In the keynote, we explain how React 18 fits into our mission to make it easy for developers to build great user experiences

Shruti Kapoor demonstrated how to use the new features in React 18

Shaundai Person gave us an overview of streaming server rendering with Suspense

Below is a full overview of what to expect in this release, starting with Concurrent Rendering.

Note for React Native users: React 18 will ship in React Native with the New React Native Architecture. For more information, see the React Conf keynote here.

What is Concurrent React?

The most important addition in React 18 is something we hope you never have to think about: concurrency. We think this is largely true for application developers, though the story may be a bit more complicated for library maintainers.

Concurrency is not a feature, per se. It’s a new behind-the-scenes mechanism that enables React to prepare multiple versions of your UI at the same time. You can think of concurrency as an implementation detail — it’s valuable because of the features that it unlocks. React uses sophisticated techniques in its internal implementation, like priority queues and multiple buffering. But you won’t see those concepts anywhere in our public APIs.

When we design APIs, we try to hide implementation details from developers. As a React developer, you focus on what you want the user experience to look like, and React handles how to deliver that experience. So we don’t expect React developers to know how concurrency works under the hood.

However, Concurrent React is more important than a typical implementation detail — it’s a foundational update to React’s core rendering model. So while it’s not super important to know how concurrency works, it may be worth knowing what it is at a high level.

A key property of Concurrent React is that rendering is interruptible. When you first upgrade to React 18, before adding any concurrent features, updates are rendered the same as in previous versions of React — in a single, uninterrupted, synchronous transaction. With synchronous rendering, once an update starts rendering, nothing can interrupt it until the user can see the result on screen.

In a concurrent render, this is not always the case. React may start rendering an update, pause in the middle, then continue later. It may even abandon an in-progress render altogether. React guarantees that the UI will appear consistent even if a render is interrupted. To do this, it waits to perform DOM mutations until the end, once the entire tree has been evaluated. With this capability, React can prepare new screens in the background without blocking the main thread. This means the UI can respond immediately to user input even if it’s in the middle of a large rendering task, creating a fluid user experience.

Another example is reusable state. Concurrent React can remove sections of the UI from the screen, then add them back later while reusing the previous state. For example, when a user tabs away from a screen and back, React should be able to restore the previous screen in the same state it was in before. In an upcoming minor, we’re planning to add a new component called <Offscreen> that implements this pattern. Similarly, you’ll be able to use Offscreen to prepare new UI in the background so that it’s ready before the user reveals it.

Concurrent rendering is a powerful new tool in React and most of our new features are built to take advantage of it, including Suspense, transitions, and streaming server rendering. But React 18 is just the beginning of what we aim to build on this new foundation.

Gradually Adopting Concurrent Features

Technically, concurrent rendering is a breaking change. Because concurrent rendering is interruptible, components behave slightly differently when it is enabled.

In our testing, we’ve upgraded thousands of components to React 18. What we’ve found is that nearly all existing components “just work” with concurrent rendering, without any changes. However, some of them may require some additional migration effort. Although the changes are usually small, you’ll still have the ability to make them at your own pace. The new rendering behavior in React 18 is only enabled in the parts of your app that use new features.

The overall upgrade strategy is to get your application running on React 18 without breaking existing code. Then you can gradually start adding concurrent features at your own pace. You can use <StrictMode> to help surface concurrency-related bugs during development. Strict Mode doesn’t affect production behavior, but during development it will log extra warnings and double-invoke functions that are expected to be idempotent. It won’t catch everything, but it’s effective at preventing the most common types of mistakes.

After you upgrade to React 18, you’ll be able to start using concurrent features immediately. For example, you can use startTransition to navigate between screens without blocking user input. Or useDeferredValue to throttle expensive re-renders.

However, long term, we expect the main way you’ll add concurrency to your app is by using a concurrent-enabled library or framework. In most cases, you won’t interact with concurrent APIs directly. For example, instead of developers calling startTransition whenever they navigate to a new screen, router libraries will automatically wrap navigations in startTransition.

It may take some time for libraries to upgrade to be concurrent compatible. We’ve provided new APIs to make it easier for libraries to take advantage of concurrent features. In the meantime, please be patient with maintainers as we work to gradually migrate the React ecosystem.

For more info, see our previous post: How to upgrade to React 18.

Suspense in Data Frameworks

In React 18, you can start using Suspense for data fetching in opinionated frameworks like Relay, Next, Hydrogen, or Remix. Ad hoc data fetching with Suspense is technically possible, but still not recommended as a general strategy.

In the future, we may expose additional primitives that could make it easier to access your data with Suspense, perhaps without the use an opinionated framework. However, Suspense works best when it’s deeply integrated into your application’s architecture: your router, your data layer, and your server rendering environment. So even long term, we expect that libraries and frameworks will play a crucial role in the React ecosystem.

As in previous versions of React, you can also use Suspense for code splitting on the client with React.lazy. But our vision for Suspense has always been about much more than loading code — the goal is to extend support for Suspense so that eventually, the same declarative Suspense fallback can handle any asynchronous operation (loading code, data, images, etc).

Server Components is Still in Development

Server Components is an upcoming feature that allows developers to build apps that span the server and client, combining the rich interactivity of client-side apps with the improved performance of traditional server rendering. Server Components is not inherently coupled to Concurrent React, but it’s designed to work best with concurrent features like Suspense and streaming server rendering.

Server Components is still experimental, but we expect to release an initial version in a minor 18.x release. In the meantime, we’re working with frameworks like Next, Hydrogen, and Remix to advance the proposal and get it ready for broad adoption.

What’s New in React 18

New Feature: Automatic Batching

Batching is when React groups multiple state updates into a single re-render for better performance. Without automatic batching, we only batched updates inside React event handlers. Updates inside of promises, setTimeout, native event handlers, or any other event were not batched in React by default. With automatic batching, these updates will be batched automatically:

For more info, see this post for Automatic batching for fewer renders in React 18.

New Feature: Transitions

A transition is a new concept in React to distinguish between urgent and non-urgent updates.

Urgent updates reflect direct interaction, like typing, clicking, pressing, and so on.

Transition updates transition the UI from one view to another.

Urgent updates like typing, clicking, or pressing, need immediate response to match our intuitions about how physical objects behave. Otherwise they feel “wrong”. However, transitions are different because the user doesn’t expect to see every intermediate value on screen.

For example, when you select a filter in a dropdown, you expect the filter button itself to respond immediately when you click. However, the actual results may transition separately. A small delay would be imperceptible and often expected. And if you change the filter again before the results are done rendering, you only care to see the latest results.

Typically, for the best user experience, a single user input should result in both an urgent update and a non-urgent one. You can use startTransition API inside an input event to inform React which updates are urgent and which are “transitions”:

Updates wrapped in startTransition are handled as non-urgent and will be interrupted if more urgent updates like clicks or key presses come in. If a transition gets interrupted by the user (for example, by typing multiple characters in a row), React will throw out the stale rendering work that wasn’t finished and render only the latest update.

useTransition: a hook to start transitions, including a value to track the pending state.

startTransition: a method to start transitions when the hook cannot be used.

Transitions will opt in to concurrent rendering, which allows the update to be interrupted. If the content re-suspends, transitions also tell React to continue showing the current content while rendering the transition content in the background (see the Suspense RFC for more info).

See docs for transitions here.

New Suspense Features

Suspense lets you declaratively specify the loading state for a part of the component tree if it’s not yet ready to be displayed:

Suspense makes the “UI loading state” a first-class declarative concept in the React programming model. This lets us build higher-level features on top of it.

We introduced a limited version of Suspense several years ago. However, the only supported use case was code splitting with React.lazy, and it wasn’t supported at all when rendering on the server.

In React 18, we’ve added support for Suspense on the server and expanded its capabilities using concurrent rendering features.

Suspense in React 18 works best when combined with the transition API. If you suspend during a transition, React will prevent already-visible content from being replaced by a fallback. Instead, React will delay the render until enough data has loaded to prevent a bad loading state.

For more, see the RFC for Suspense in React 18.

New Client and Server Rendering APIs

In this release we took the opportunity to redesign the APIs we expose for rendering on the client and server. These changes allow users to continue using the old APIs in React 17 mode while they upgrade to the new APIs in React 18.

React DOM Client

These new APIs are now exported from react-dom/client:

createRoot: New method to create a root to render or unmount. Use it instead of ReactDOM.render. New features in React 18 don’t work without it.

hydrateRoot: New method to hydrate a server rendered application. Use it instead of ReactDOM.hydrate in conjunction with the new React DOM Server APIs. New features in React 18 don’t work without it.

Both createRoot and hydrateRoot accept a new option called onRecoverableError in case you want to be notified when React recovers from errors during rendering or hydration for logging. By default, React will use reportError, or console.error in the older browsers.

See docs for React DOM Client here.

React DOM Server

These new APIs are now exported from react-dom/server and have full support for streaming Suspense on the server:

renderToPipeableStream: for streaming in Node environments.

renderToReadableStream: for modern edge runtime environments, such as Deno and Cloudflare workers.

The existing renderToString method keeps working but is discouraged.

See docs for React DOM Server here.

New Strict Mode Behaviors

In the future, we’d like to add a feature that allows React to add and remove sections of the UI while preserving state. For example, when a user tabs away from a screen and back, React should be able to immediately show the previous screen. To do this, React would unmount and remount trees using the same component state as before.

This feature will give React apps better performance out-of-the-box, but requires components to be resilient to effects being mounted and destroyed multiple times. Most effects will work without any changes, but some effects assume they are only mounted or destroyed once.

To help surface these issues, React 18 introduces a new development-only check to Strict Mode. This new check will automatically unmount and remount every component, whenever a component mounts for the first time, restoring the previous state on the second mount.

Before this change, React would mount the component and create the effects:

With Strict Mode in React 18, React will simulate unmounting and remounting the component in development mode:

See docs for ensuring resusable state here.

New Hooks

useId

useId is a new hook for generating unique IDs on both the client and server, while avoiding hydration mismatches. It is primarily useful for component libraries integrating with accessibility APIs that require unique IDs. This solves an issue that already exists in React 17 and below, but it’s even more important in React 18 because of how the new streaming server renderer delivers HTML out-of-order. See docs here.

useTransition

useTransition and startTransition let you mark some state updates as not urgent. Other state updates are considered urgent by default. React will allow urgent state updates (for example, updating a text input) to interrupt non-urgent state updates (for example, rendering a list of search results). See docs here

useDeferredValue

useDeferredValue lets you defer re-rendering a non-urgent part of the tree. It is similar to debouncing, but has a few advantages compared to it. There is no fixed time delay, so React will attempt the deferred render right after the first render is reflected on the screen. The deferred render is interruptible and doesn’t block user input. See docs here.

useSyncExternalStore

useSyncExternalStore is a new hook that allows external stores to support concurrent reads by forcing updates to the store to be synchronous. It removes the need for useEffect when implementing subscriptions to external data sources, and is recommended for any library that integrates with state external to React. See docs here.

Note

useSyncExternalStore is intended to be used by libraries, not application code.

useInsertionEffect

useInsertionEffect is a new hook that allows CSS-in-JS libraries to address performance issues of injecting styles in render. Unless you’ve already built a CSS-in-JS library we don’t expect you to ever use this. This hook will run after the DOM is mutated, but before layout effects read the new layout. This solves an issue that already exists in React 17 and below, but is even more important in React 18 because React yields to the browser during concurrent rendering, giving it a chance to recalculate layout. See docs here.

Note

useInsertionEffect is intended to be used by libraries, not application code.

Why React

We have decided to create a list of the top React admin templates for developers that are actual and trending in 2022. Each year, we see that trends are changing, but React technology stays on top of all among JavaScript. We regularly make such listings to highlight the recent React admin dashboard that appeared on the market, for instance, you can check it here, and here.

If you need to build a powerful application and host your full-stack web application using React, Vue, Node.js, you can boost your development process with the Flatlogic platform. Starting with this CMS builder approach, you can create and host any web application reducing the time and expenses on web development.

But why do we push React forward again and again? React dashboards, and basically any admin dashboard built on React is a meaningful share representing a big part of the market.

Just check the recent statistics of React usage, US, UK, Germany and Canada take the leading positions in the world of web development according to the trends of buildwith.

Almighty React is chosen for its engaging and flexible nature. The insights of Stackoverflow and the survey of 2021 also showed that React.js library remains the most wanted and demanded technology easily surpassing jQuery among users.

However the world of JavaScript libraries is inexhaustible, and we urge you to stay tuned and keep abreast of modern web development trends keeping up with the recent tech advances.

How to Choose Which React Template is Better?

Finding an admin template that you love might take a little bit of time, but they’re easy to find on a professional marketplace, just like Flatlogic.

Frankly speaking, by and large most of these React dashboard samples are responsive, Figma ready, well documented, and have a range of UI components inside, so let’s dive into the core criteria by which we define the best admin template, UI kit, starter kit, or whatever it may be named.

Once we have already cited this ultimate list as an example of your checklist while choosing an admin template. Surely, you can make choice by the UI and the visual appearance of admin template, but the dashboard and the starter kits compounds are still the crucial take-away points to set out:

Design quality

I got to talk to Sarah Fossheim this week! One of the impressive things that Sarah does is near photograph-quality recreations of iconic old technology in HTML & CSS. I enjoyed the fact that neither of us quite totally knows what some of these machines even did, but appreciate their incredible aesthetics. Perhaps my favorite part of the conversation was emphasizing that this work, while almost being a relaxing hobby in the vein of knitting, still levels up one’s CSS ability. Sarah got me thinking that it’s not just CSS, but perhaps equally or more importantly HTML ability, the ability to break down sections into components and think about how smaller parts become a whole, just like any other website work.

MySQL: What is it?

MySQL is an open-source relational database management system that allows you to manage relational databases based on Structured Query Language (SQL) queries. It supports multiple platforms such as Windows, Ubuntu, Linux, macOS, etc. It was developed by Swedish company MySQL AB in 1994, which was acquired in 2008 by American tech company Sun Microsystems. Afterwards, in 2010 the American giant Oracle acquired Sun Microsystems, and since then MySQL de-facto belongs to Oracle.

The database is a structured set of data, for example, a straightforward shopping list or places to store massive quantities of information throughout a business network. The relational database is a digital repository that collects data and organizes it according to a relational model, where tables consist of rows and columns and the relationships between data items follow a strict logical structure. MySQL is a simple software toolkit we can use to perform, manage, and execute queries on such a database. 

Why use MySQL?

MySQL is the most popular RDBMS, let’s look at why this is like that:

Easy-to-use. The only thing you should learn before using MySQL is a basic knowledge of SQL (Structured Query Language).

Open-source. Virtually anyone can install, modify, and use MySQL because of its incredible ease of use. The source code uses the GPL, that is, the GNU General Public License, which specifies guidelines for what you can and can’t do with this application.

High Productivity. MySQL is possibly the fastest database language, according to a multitude of standard tests.

Scalability. MySQL supports multi-threading, meaning the ability of systems to easily operate on small and large quantities of data, clusters of machines, etc. 

Security. MySQL is composed of a strong security level of data that protects confidential data from attackers. The interface is also secure because it has a versatile password system and guarantees host-based validation before accessing the database. 

Multiple data types. MySQL contains many data types, like integers, float, double, char, varchar, text, blob, date, time, DateTime, timestamp, etc.

Community. The community is very large, so if you get stuck anywhere then you can get help from the community.

Client-Server Architecture. MySQL is a client-server based architecture and accessible from anywhere through networking, i.e. each machine communicates with the server via an Internet connection. The server handles requests from the client and returns the result to the client machine. Clients can send queries to remote servers using an Internet connection, but the main requirement is keeping the server active at the time.

Who uses MySQL

MySQL is the most popular and useful database system, the largest and most important companies are probably choosing it such as:

Uber
Twitter
Slack
Airbnb
Pinterest
Amazon

Using the Flatlogic Platform you can also generate an application with a MySQL database system.

How to create your app with Flatlogic Platform

Step 1. Choosing the Tech Stack

In this step, you’re setting the name of your application and choosing the stack: Frontend, Backend, and Database.

Step 2. Choosing the Starter Template

In this step, you’re choosing the design of the web app.

Step 3. Schema Editor

In this part 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;
Blog.

Like all databases in MySQL, there are such types of table relationships as relation_one, relation_many. You can enforce the relationships by defining the right foreign key constraints on the columns.

Relation (one) – one-sided relation capable of storing one or another entity, for example, Employee: [{ name: ‘John’}].
Relation (many) – two-sided relation capable of storing any number of other entities, for example, Employee: [{ name: ‘John’ }, { name: ‘Joe’ }].

Afterwards, you can deploy your application and in a few minutes, you will get a fully functional CMS application with a MySQL database system.

Programming languages all have erected-in data types, but these frequently differ from one language to another. This post attempts to list the erected-in data structures available in JavaScript and what properties they have.

In this post, you will learn about the various data types available in JavaScript with the help of examples.

JavaScript provides different data types to hold different types of values. There are two types of data types in JavaScript.

Primitive data type.
Non-primitive (reference) data type.

 

Primitive data type.

The JavaScript language provides 6 primitive data types:

Undefined
Null
Number
String
Boolean
Symbol

Undefined:

A variable that has not been assigned a value has the value undefined.

var language; //variable declared but not defined.
console.log(language); // Output: undefined

Null:

A variable has been defined with a null value. It is like as undefined. It’s store nothing.

You can assign null to a variable to denote that currently, that variable does not have any value but it will have later on. A null means absence of a value.

var language = null; //It holds null value
var lang; // It holds undefined value

console.log(language == lang); // it return true, value is same of language and lang but data type different
console.log(language === lang); // it is return false, value is same of language and lang but data type different

Number:

There is only one number type. There is no specific type for integers. The number is a primitive data type used for positive or negative integer, float, binary, octal, hexadecimal, and exponential values in JavaScript

String:

A string in JavaScript is a sequence of characters. It is textual content. It can be created with the help of single or double-quotes.

var str1 = “Hello, World!”;
var str2 = ‘Hi, Welcome to JavaScript Tutorial’;

Boolean:

It is logical a entity. A variable can have two values true or false.

var isActive = true;
var isDisabled = false;

Symbol:

New in ECMAScript6. A Symbol is a unique and immutable identifier.

var x = Symbol();
var y = Symbol(10);
var z = Symbol(‘Hello’);

 

2. Non-primitive (reference) data type.

Non-primitive data types are called reference types because they refer to objects. The ‘object’ is a non-primitive data type in JavaScript. Arrays and Functions in JavaScript belong to the ‘object’ data type.

Object:

An object in JavaScript contains key-value pairs in its address. When we refer to obj1, we are actually referring to the address in memory which contains the value {a: 5, b: 6}, instead of the value {a: 5, b: 6} directly.

var obj1 = { a: 5, b: 6 };

We can change or mutate the value of obj1.

obj1[a] =7;
console.log(obj1) // will return the value {a: 7, b: 6}

Array:

With the help of an array, we can store more than one element under a single name.

// Call it with no arguments
var a = new Array();

// Call it with single numeric argument
var b = new Array(10);

// Explicitly specify two or
// more array elements
var d = new Array(1, 2, 3, “Hello”);

static string legacy_code(int input)
{
// some magic process
const int magicNumber = 7;

var intermediaryValue = input + magicNumber;

return “The answer is ” + intermediaryValue;
}

When dealing with a project more than a few years old, the issue of legacy code crops up time and time again. In this case, you have a function that’s called from lots of different client applications, so you can’t change it without breaking the client apps.

I’m using the code example above to keep the illustration simple, but you have to imagine that this function “legacy_code(int)”, in reality, could be hundreds of lines long, with lots of quirks and complexities. So you really don’t want to duplicate it.

Now, imagine, that as an output, I want to have just the intermediary value, not the string “The answer is …”. My client could parse the number out of the string, but that’s a horrible extra step to put on the client.

Otherwise you could create “legacy_code_internal()” that returns the int, and legacy_code() calls legacy_code_internal() and adds the string. This is the most common approach, but can end up with a rat’s nest of _internal() functions.

Here’s another approach – you can tell me what you think :

static string legacy_code(int input, Action<int> intermediary = null)
{
// some magic process
const int magicNumber = 7;

var intermediaryValue = input + magicNumber;

if (intermediary != null) intermediary(intermediaryValue);

return “The answer is ” + intermediaryValue;
}

Here, we can pass an optional function into the legacy_code function, that if present, will return the intermediaryValue as an int, without interfering with how the code is called by existing clients.

A new client looking to use the new functionality could call;

int intermediaryValue = 0;
var answer = legacy_code(4, i => intermediaryValue = i);
Console.WriteLine(answer);
Console.WriteLine(intermediaryValue);

This approach could return more than one object, but this could get very messy.

Introduction

In this article, we will take a look at how to create a simple gRPC client with .NET and communicate with a server. This is the final post of the blog series where we talk about building gRPC services.

Motivation

This is the second part of an articles series on gRPC. If you want to jump ahead, please feel free to do so. The links are down below.

Introduction to gRPC
Building a gRPC server with Go
Building a gRPC client with .NET
Building a gRPC client with Go

Building a gRPC client with .NET (You are here)

Please note that this is intended for anyone who’s interested in getting started with gRPC. If you’re not, please feel free to skip this article.

Plan

The plan for this article is as follows.

Scaffold a .NET console project.
Implementing the gRPC client.
Communicating with the server.

In a nutshell, we will be generating the client for the server we built in our previous post.

?  As always, all the code samples documentation can be found at: https://github.com/sahansera/dotnet-grpc

Prerequisites

.NET 6 SDK
Visual Studio Code or IDE of your choice
gRPC compiler

Please note that I’m using some of the commands that are macOS specific. Please follow this link to set it up if you are on a different OS.

To install Protobuf compiler:

Project Structure

We can use .NET’s tooling to generate a sample gRPC project. Run the following command at the root of your workspace. Remember how we used dotnet new grpc command to scaffold the server project? For this one though, it can simply be a console app.

Your project structure should look like this.

You must be wondering if this is a console app how does it know how to generate the client stubs? Well, it doesn’t. You have to add the following packages to the project first.

Once everything’s installed, we can proceed with the rest of the steps.

Generating the client stubs

We will be using the same Protobuf files that we generated in our previous step. If you haven’t seen that already head over to my previous post.

Open up the BookshopClient.csproj file you need to add the following lines:

As you can see we will be reusing our Bookshop.proto file. in this example too. One thing to note here is that we have updated the GrpcServices attribute to be Client.

Implementing the gRPC client

Let’s update the Program.cs file to connect to and get the response from the server.

This is based on the example given on the Microsoft docs site btw. What I really like about the above code is how easy it is to read. So here’s what happens.

We first create a gRPC channel with GrpcChannel.ForAddress to the server by giving its URI and port. A client can reuse the same channel object to communicate with a gRPC server. This is an expensive operation compared to invoking a gRPC method on the server. You can also pass in a GrpcChannelOptions object as the second parameter to define client options. Here’s a list for that.
Then we use the auto-generated method Inventory.InventoryClient by leveraging the channel we created above. One thing to note here is that, if your server has multiple services, you can still use the same channel object for all of those.
We call the GetBookListAsync on our server. By the way, this is a Unary call, we will go through other client-server communication mechanisms in a separate post.
Our GetBookList method gets called on the server and returns the list of books.

Now that we know how the requests work, let’s see this in action.

Communicating with the server

Let’s spin up the server that we built in my previous post first. This will be up and running at port 5000.

For the client-side, we invoke a similar command.

And in the terminal, we will get the following outputs.

Nice! as you can see it’s not that hard to get everything working ? One thing to note is that we left out the details about TLS and different ways to communicate with the server (i.e. Unary, streaming etc.). I will cover such topics in-depth in the future.

Conclusion

In this article, we looked at how to reuse our Protobuf files to create a client to interact with the server we created in the previous post.

I hope this article series cleared up a lot of confusion that you had about gRPC. Please feel free to share your questions, thoughts, or feedback in the comments section below. Until next time ?
