Node.js
Node.js
As an asynchronous event-driven JavaScript runtime, Node.js is designed to build scalable network applications. Upon each connection, the callback is fired, but if there is no work to be done, Node.js will sleep. This is in contrast to today's more common concurrency model, in which OS threads are employed. Thread-based networking is relatively inefficient and very difficult to use. Furthermore, users of Node.js are free from worries of dead-locking the process, since there are no locks. Almost no function in Node.js directly performs I/O, so the process never blocks except when the I/O is performed using synchronous methods of Node.js standard library. Because nothing blocks, scalable systems are very reasonable to develop in Node.js. Node.js is similar in design to, and influenced by, systems like Ruby's Event Machine and Python's Twisted. Node.js takes the event model a bit further. It presents an event loop as a runtime construct instead of as a library. -

Claudia
Claudia
Claudia makes it easy to deploy Node.js projects to AWS Lambda and API Gateway. It automates all the error-prone deployment and configuration tasks and sets everything up the way JavaScript developers expect out of the box. This means that you can get started with Lambda microservices easily, and focus on solving important business problems instead of dealing with AWS deployment workflows. AWS Lambda and API Gateway are incredibly flexible, but they can be tedious to set up, especially for simple scenarios. Running Node.js functions requires you to iron out quite a few quirks, that aren't exactly well documented. Claudia automates all those steps for you. Deploy and update using a single command. Just use standard NPM packages, no need to learn Swagger. Skip all the boilerplate and just focus on your work. Manage multiple versions easily. Get started in minutes, with a very low learning curve. -

Flexible APIs for custom assertions, runners, and reporters mean you can extend QUnit to fit your needs. Getting started with QUnit for Node.js projects is quick and easy. First, install the QUnit package using npm. You can now run the test suite through the QUnit CLI. It is recommended that you run the QUnit command via an npm script, which will find the QUnit command automatically from your local dependencies. Check out the API documentation to learn more about the QUnit APIs for organizing tests and making assertions.QUnit follows the Node.js Long-term Support (LTS) schedule and provides support for current, active LTS, and maintenance LTS releases.Starting Price: Free -

TypeScript
TypeScript
TypeScript adds additional syntax to JavaScript to support a tighter integration with your editor. Catch errors early in your editor. TypeScript code converts to JavaScript, which runs anywhere JavaScript runs: In a browser, on Node.js or Deno and in your apps. TypeScript understands JavaScript and uses type inference to give you great tooling without additional code. TypeScript was used by 78% of the 2020 State of JS respondents, with 93% saying they would use it again. The most common kinds of errors that programmers write can be described as type errors: a certain kind of value was used where a different kind of value was expected. This could be due to simple typos, a failure to understand the API surface of a library, incorrect assumptions about runtime behavior, or other errors.Starting Price: Free -

Navigate to the directory where you wish to create your project and type cordova create <path>. After creating a Cordova project, navigate to the project directory. From the project directory, you need to add a platform for which you want to build your app. Cordova wraps your HTML/JavaScript app into a native container which can access the device functions of several platforms. These functions are exposed via a unified JavaScript API, allowing you to easily write one set of code to target nearly every phone or tablet on the market today and publish to their app stores. -

A seamless JavaScript code coverage library. Blanket.js is a code coverage tool for JavaScript that aims to be easy to install, easy to use, and easy to understand. Blanket.js can be run seamlessly or can be customized for your needs. JavaScript code coverage compliments your existing JavaScript tests by adding code coverage statistics (which lines of your source code are covered by your tests). Parsing the code using Esprima and node-falafel, and instrumenting the file by adding code tracking lines. Connecting to hooks in the test runner to output the coverage details after the tests have been completed. A Grunt plugin has been created to allow you to use Blanket like a "traditional" code coverage tool (creating instrumented copies of physical files, as opposed to live-instrumenting). Runs the QUnit-based Blanket report headlessly using PhantomJS. Results are displayed on the console, and the task will cause Grunt to fail if any of your configured coverage thresholds are not met.Starting Price: Free -

RequireJS
RequireJS
RequireJS is a JavaScript file and module loader. It is optimized for in-browser use, but it can be used in other JavaScript environments, like Rhino and Node. Using a modular script loader like RequireJS will improve the speed and quality of your code. This setup assumes you keep all your JavaScript files in a "scripts" directory in your project. To take full advantage of the optimization tool, it is suggested that you keep all inline script out of the HTML, and only reference require.js with a requirejs call like so to load your script. All of them map to loading some/path/some/module.js. Ideally we could choose the CommonJS syntax, since it is likely to get more common over time, and we want to reuse code.Starting Price: Free -

CoffeeScript
CoffeeScript
Underneath that awkward Java-esque patina, JavaScript has always had a gorgeous heart. CoffeeScript is an attempt to expose the good parts of JavaScript in a simple way. The golden rule of CoffeeScript is: “It’s just JavaScript.” The code compiles one-to-one into the equivalent JS, and there is no interpretation at runtime. You can use any existing JavaScript library seamlessly from CoffeeScript (and vice-versa). The compiled output is readable, pretty printed, and tends to run as fast or faster than the equivalent handwritten JavaScript. Most modern JavaScript features that CoffeeScript supports can run natively in Node 7.6+, meaning that Node can run CoffeeScript’s output without any further processing required. This list may be incomplete, and excludes versions of Node that support newer features behind flags; please refer to node.green for full details. You can run the tests in your browser to see what your browser supports.Starting Price: Free -

Maqetta is an open source project that provides WYSIWYG visual authoring of HTML5 user interfaces. The Maqetta application itself is authored in HTML, and therefore runs in the browser without requiring additional plugins or downloads. Maqetta is available under a commercial-friendly open source license. You can download the source code and install it on your own server, customize the code to fit your needs and/or contribute improvements to the open source project. The HTML pages created by Maqetta typically work across all popular browsers, including IE (caveat: this depends on the JavaScript toolkit you use and coding details). But if you want to run the Maqetta application, you'll need to use a recent release of one of the following browsers, all of which support the HTML5 features that Maqetta requires. The project's code is built using 100% open standards technologies. -

Moment.js
Moment.js
A JavaScript date library for parsing, validating, manipulating, and formatting dates. Moment was designed to work both in the browser and in Node.js. All code should work in both of these environments, and all unit tests are run in both of these environments. Moment.js has been successfully used in millions of projects. As of September 2020, Moment gets over 12 million downloads per week! Moment has evolved somewhat over the years, but it has essentially the same design as it did when it was created in 2011. Moment works well on Internet Explorer 8 and higher. Some libraries are split into modules, plugins, or companion libraries. Some libraries use the ECMAScript Intl API for locales, time zones, or both. Some libraries still provide their own locale and time zone files as Moment and Moment-Timezone do. Because different locales define week of year numbering differently, Moment.js added options to get/set the localized week of the year.Starting Price: Free
