JavaScript is still the world’s most popular programming language. Producing anything on the web requires at least a working knowledge of JavaScript. Given the multiple frameworks and libraries, you’ll need to interact with. And with its development into important new technologies such as blockchain. JavaScript seems set to remain relevant for the foreseeable future.

The popularity of JavaScript goes accompanied by a surplus of tools to make coding in JavaScript easier. In today’s post is a list of the best and popular tools for JavaScript. Below I’ve placed them into categories that define some of the important parts of the development process.

IDEs and Editors

It’s the place where you write your code is important. Some devs some prefer editors and others prefer Integrated Development Environments (IDEs). While editors make for smoother and responsive performance, IDEs are generally used for more complex projects.

As they offer to debug functionality and support for ALM systems which can integrate with platforms for version control and more.

Visual Studio Code

Vs Code

Visual Studio Code is a lightweight but powerful source code editor which runs on your desktop and is available for Windows, macOS and Linux. It includes support for debugging, auto-indentation, Git control, syntax highlighting, code refactoring, and more.

WebStorm

Jetbrains Webstorm

A JavaScript IDE made by JetBrains. WebStorm offers support for intelligent code completion, on-the-fly error detection, powerful navigation. And refactoring for JS, TypeScript, stylesheet languages and the most popular frameworks.

Atom

Atom Code Editor

This text editor written by the developers  at GitHub. It comes with plenty of features out of the box. Such as cross-platform editing, a built-in package manager, smart auto-completion, find and replace, etc. So there’s  plenty of themes to customise its look and feel to suit your needs.

Task Runners & Module Bundlers

These tools have become a significant component in any JavaScript developer’s workflow. They help with tasks such as web page refreshing, minification, unit testing.

And while you will find some build tools will have a learning curve. They can help automate common tasks in programming.

Grunt

Grunt

A JavaScript task runner that automates repetitive tasks like minification, compilation, linting, unit testing, and more. Grunt has a huge ecosystem with over 6,000 plugins.

Gulp

Gulp

Gulp defines and runs time-consuming tasks. But different from Grunt. Gulp defines tasks as JavaScript functions instead of configuration objects.

ParcelJS

Parcel

This module bundler enables multicore compilation. Which makes it blazingly fast. Out of the box, Parcel supports JS, CSS, HTML, and file assets.

Rollup.js

Rollup

Rollup is a module bundler for JavaScript which compiles small pieces of code into something larger. And more complex, such as a library or application. It uses the standardised format for code modules included in the ES6 revision of JavaScript. ES modules let you freely and seamlessly combine the most useful individual functions from your favourite libraries.

WebPack

Webpack

Software that bundles all your JavaScript apps. But as well as all kinds of different assets like images, font and stylesheets. It supports ESM and CommonJS.

Browserify

Browserify

This is a JavaScript tool where you can write Node.js style modules and compile them to use in the browser. It bundles all the required modules in a file called bundle.js

Documentation Software

Software without documentation is any developers nightmare. Software with inadequately written documentation is arguably even worse, documentation explains how the software operates and how it should be used.

But writing documentation is hard. It’s complicated, time-consuming, and boring too. Fortunately there’s are some software documentation tools which ease some of the burdens of writing documentation. Which can make the process faster.

Docco

Docco

Docco is a quick-and-dirty documentation generator. Written in Literate CoffeeScript. It produces an HTML document that displays your comments intermingled with your code. All prose is passed through Markdown, and code is passed through Highlight.js syntax highlighting.

JSDoc

Jsdoc

Markup language used to annotate JS source code files. Which is then used to produce documentation in formats like HTML and RTF.

Swagger

Swagger

Helps across the entire API life-cycle. From design to documentation. It is a set of rules and tools for describing APIs. and it’s language-agnostic and readable both by humans and machines.

YUIDoc

Yuidoc

This is a Node.js app that generates API docs from comments in the source code. Also, it supports a wide range of JS coding styles and its output is API docs formatted as a set of HTML pages.

Testing Frameworks

Software testing is a necessary part of the development process. And you need to figure out whether all your code works under a changing set of circumstances. It’s how you can identify errors, gaps or missing requirements as compared to the actual project requirements.

These testing tools come in handy. Due to the growing complexity of apps makes it increasingly cumbersome to test software manually. These tools run a test script and generate test results automatically.

Jasmine

Jasmine

A behavior-driven development framework for testing JS code. Jasmine does not depend on any other JavaScript frameworks. Nor does it require a DOM to work. It has clean and easy to understand syntax. Which makes it easy to write tests.

Jest

Jest

Jest is a delightful JavaScript Testing Framework with a focus on simplicity. It works with projects using: Babel, TypeScript, Node, React, Angular, Vue and more!

Mocha

Mocha

Mocha is a feature-rich JavaScript test framework running on Node.js and in the browser. Making asynchronous testing simple and fun. It tests run serially, allowing for flexible and accurate reporting. Also while mapping uncaught exceptions to the correct test cases.

Linting Software

Every JavaScript developer should already be using linting software to maintain the quality of their code. As it improves the readability of your code, identifies structural problems. And finds those syntax errors while allowing you to discover problems in your code without having to execute it.

ESLint

Eslinit

ESLint is an open-source plugin for JS and JSX, to be used mainly on the command line and all rules are plugg-able, so devs can create their own linting rules.

Flow

Flow

A JS code checker developed by Facebook, it checks your code for errors through static type annotations but needs only a minimum of such descriptions. Flow will understand the rest.

JSHint

Js Hint

JSHint is a community-driven tool that detects errors and potential problems in JavaScript code. Since JSHint is so flexible, you can easily adjust it in the environment you expect your code to execute. JSHint is open source and. It will always stay this way.

Prettier

Prettier

A fully automatic style guide. Which leaves style debates at the door. So you can focus on more important decisions.

Debuggers

Debugging tools make debugging less time-consuming and difficult. As they help you achieve more accurate results. A debugger tool can become your best friend in frustrating moments.

Chrome Dev Tools

Chrome Devtools

A set of tools built directly into the Google Chrome browser. The Chrome Dev Tools have multiple utilities that help you debug JS code step by step.

JavaScript Debugger

Javascript Debugger

Developed by the Mozilla Developer Network, the JavaScript Debugger can be used to debug in Firefox or even as a stand-alone web-app for debugging code in other browsers or Node.js.

JavaScript Development Tools (JSDT)

Eclipse

This provides plugins that support debugging JavaScript using Rhino and Crossfire. It can debug JavaScript in all major browsers.

Security Analysers

Cybersecurity has become the uppermost priority for companies and countries. As vulnerable software is the common attack for hackers. As a developer, the security of anything you code should be a priority.

Below are some JavaScript security analysers that look into your software’s dependencies and lessen some of the security risks that come with depending on other people’s plugins and frameworks.

Retire.js

Retire.js

Retire.js helps detect if you have versions of dependencies that has known security vulnerabilities. It is a command line scanner. But also has a Grunt plugin, a Chrome/Firefox extension, and a Burp/OWASP Zap plugin.

Acunetix

Acunetix

Acunetix is an application security testing platform that is here to secure your websites apps, and APIs. It uses both black-box and gray-box hacking techniques to help find vulnerabilities.

Snyk

Snyk is a developer-first application security analyser that find and automatically fix vulnerabilities in your code, open-source dependencies, containers, and infrastructure as code.

OSS Index

Oss Index

OSS Index is a catalogue of open-source components and scanning tools to help developers identify vulnerabilities, understand risk. And keep their software safe. It supports multiple ecosystems, such as Alpine, NPM, Bower, Drupal, RubyGems and plenty more.

Package Managers

Having that software that can automatically install, upgrade, configure and remove the packages that is maintained in the repositories. Also, package managers also look at your dependencies and make sure new versions of packages don’t break your code.

NPM

Npm

The default package manager for Node.js. Although it can be used for front-end development too. It’s the largest software registry in the world, with over 1.2 million packages.

Yarn

Yarn Js

The main competitor of npm. Developed by Facebook. Yarn offered some significant advantages over npm when released in 2016. Although npm has since caught up considerably.
