SuperTest
Super-agent driven library for testing node.js HTTP servers
A super-agent driven library for testing node.js HTTP servers using a fluent API. The motivation with this module is to provide a high-level abstraction for testing HTTP, while still allowing you to drop down to the lower-level API provided by superagent. Install SuperTest as an npm module and save it to your package.json file as a development dependency. You may pass an http.Server, or a Function to request(), if the server is not already listening for connections then it is bound to an ephemeral port for you so there is no need to keep track of ports. One thing to note, is that superagent now sends any HTTP error (anything other than a 2XX response code) to the callback as the first argument if you do not add a status code expect (i.e. .expect(302)). Expectations are run in the order of definition. This characteristic can be used to modify the response body or headers before executing an assertion. -

SystemJS
Dynamic ES module loader
SystemJS is a hookable, standards-based module loader. It provides a workflow where code written for production workflows of native ES modules in browsers (like Rollup code-splitting builds), can be transpiled to the System.register module format to work in older browsers that don't support native modules, running almost-native module speeds while supporting top-level await, dynamic import, circular references and live bindings, import.meta.url, module types, import maps, integrity and Content Security Policy with compatibility in older browsers back to IE11. SystemJS allows to write and use modular javacsript code that relies on ECMAScript 6 import and export statements. One good example is moment.js library, which started publishing ECMAScript 6 source code on npm since 2.10.0 release of moment.js. SystemJS requries a transpiler to compile ECMAScript 6 javacsript into a code that could be run in current versions of browsers and node.js. -

TSDX
Zero-config CLI for TypeScript package development
Despite all the recent hype, setting up a new TypeScript (x React) library can be tough. Between Rollup, Jest, tsconfig, Yarn resolutions, TSLint, and getting VSCode to play nicely, there is just a whole lot of stuff to do (and things to screw up). TSDX is a zero-config CLI that helps you develop, test, and publish modern TypeScript packages with ease, so you can focus on your awesome new library and not waste another afternoon on the configuration. With TSDX, you can quickly bootstrap a new TypeScript project in seconds, instead of hours. TSDX will create a folder with the project template in it and install all dependencies. Once that's done, you're ready to rock. TypeScript, Rollup, Jest, ESlint, and all other plumbing are already set up with best practices. Just start editing src/index.ts (or src/index.tsx if you chose one of the React templates) and go. -

Tempus Dominus
A date/time picker widget
Tempus Dominus is the successor to the very popular "eonasdan/bootstrap-datetimepicker". The plugin provide a robust date and time picker designed to integrate into your project. The picker uses the format option to decide what components to show. Set format to LT, LTS or another valid MomentJs format string to display certain components. The picker uses MomentJs to determine the language string. You can use moment-with-locales or you can include whatever local file you need. Start of the week is based on the locale provided. This is defined by moment's locales. If you want to change it, create your own locale file or override. Looking for a template with the datepicker ready to go? Then get check out the templates provided in our website. Bootstrap.js is needed (transition and collapse are required if you're not using the full Bootstrap). -

Todoist
Building Todoist from Scratch Using React
This application (a Todoist clone) was built using create-react-app as a base, and the technologies used were React (Custom Hooks, Context), Firebase & React Testing Library. I'm hoping this gives people a better understanding of React, and I've also included SCSS in this tutorial, but the main focus is to build a real application using React! If you clone this application, click the Pizza icon on the top right, it enables dark mode! -

Toolkit for YNAB
A general purpose YNAB enhancing browser extension for Chrome
Toolkit for YNAB is a browser extension that enhances your experience with the YNAB Web Application. YNAB have released an exciting new web version. Lots of power users of the older versions are asking for options that are easily implemented in a browser extension. Rather than ask the YNAB team to implement these features, let's just do it ourselves! The Toolkit is available for Chrome and Firefox. The extension is built using Browser (Web) Extension APIs which means support for Edge should be imminent as well. Since the extension is built with Web Extensions and that is not supported by Safari, the extension itself is not supported on Safari. When/if Safari decides to support Web Extensions we will do what we can to provide support for their browser. We've decided that it's better to use the latest and greatest than to wait for browsers to support all the nice newer syntax landing in Javascript. -

TopoJSON
An extension of GeoJSON that encodes topology
TopoJSON eliminates redundancy, allowing related geometries to be stored efficiently in the same file. For example, the shared boundary between California and Nevada is represented only once, rather than being duplicated for both states. A single TopoJSON file can contain multiple feature collections without duplication, such as states and counties. Or, a TopoJSON file can efficiently represent both polygons (for fill) and boundaries (for stroke) as two feature collections that share the same arc mesh. See How To Infer Topology for a visual explanation of how TopoJSON works. See Command-Line Cartography for an introduction to TopoJSON and related tools. See TopoJSON Format Specification for the format specification. To further reduce file size, TopoJSON can use quantized delta-encoding for integer coordinates. This is similar to rounding coordinate values (e.g., LilJSON), but with greater efficiency and control over loss of information. -

Twitter-Post-Fetcher
Fetch your twitter posts without using the new Twitter 1.1 API
Allows you to get your tweets displayed on your website using JavaScript, without using new Twitter 1.1 API. Recently I was quite frustrated to find out that the old API on Twitter was depreciated and the overhead in setting up a system to perform OAUTH just to get my already publicly available tweets was too damn high. Even worse I couldn't find any simple solutions for JavaScript. All code examples were server-side. So after much thinking, I invented the following solution. It makes use of the over-bloated widgets Twitter gives us to put on our sites, cuts out all the nonsense (and nonsemantic markup), and returns to you your raw tweet text so you can do with it as you please and style it how you want on your own website - like it should be. Instructions on how to get it working with your tweets are in the code comments, just do what it says! Enjoy! -

TypeScript Koa Starter
TypeScript Koa Starter
Koa with TypeScript's application generator. Creates a new typescript koa application. application is configured to use TypeScript instead of plain JavaScript. Node Js is great for the rapid development of web-projects, but is often neglected because of the lack of type safety. TypeScript solves this issue and (along with its linter file) can even make your code more robust than some other static languages like Java. -

Typed.js
A JavaScript typing animation library
Typed.js is a library that types. Enter in any string, and watch it type at the speed you've set, backspace what it's typed, and begin a new sentence for however many strings you've set. Rather than using the strings array to insert strings, you can place an HTML div on the page and read from it. This allows bots and search engines, as well as users with JavaScript disabled, to see your text on the page. You can pause in the middle of a string for a given amount of time by including an escape character. CSS animations are built upon initialization in JavaScript. But, you can customize them at your will! -
