eslint-plugin-flowtype
Flow type linting rules for ESLint
Flow type linting rules for ESLint. This plugin exports a recommended configuration that enforces Flow type good practices. To enable this configuration use the extends property in your .eslintrc config file. ESLint is designed to be flexible and configurable for your use case. You can turn off every rule and run only with basic syntax validation or mix and match the bundled rules and your custom rules to fit the needs of your project. There are two primary ways to configure ESLint. Use JavaScript comments to embed configuration information directly into a file. Use a JavaScript, JSON, or YAML file to specify configuration information for an entire directory and all of its subdirectories. This can be in the form of a .eslintrc.* file or an eslintConfig field in a package.json file, both of which ESLint will look for and read automatically, or you can specify a configuration file on the command line. -

eslint-plugin-jsx-a11y
Static AST checker for a11y rules on JSX elements
Static AST checker for accessibility rules on JSX elements. This plugin does a static evaluation of the JSX to spot accessibility issues in React apps. Because it only catches errors in static code, use it in combination with axe-core/react to test the accessibility of the rendered DOM. Consider these tools just as one step of a larger a11y testing process and always test your apps with assistive technology. If you installed ESLint globally (using the -g flag in npm, or the global prefix in yarn) then you must also install eslint-plugin-jsx-a11y globally. To enable your custom components to be checked as DOM elements, you can set global settings in your configuration file by mapping each custom component name to a DOM element type. Enforce all elements that require alternative text have meaningful information to relay back to the end user. -

esprint
Fast eslint runner
esprint (pronounced E-S-sprint) speeds up eslint by running the linting engine across multiple threads. esprint sets up a server daemon to cache the lint status of each file in memory. It uses a watcher to determine when files change, to only lint files as necessary. It also has a CI mode where it does not set up a daemon and just lints in parallel. In order to use esprint, first place an .esprintrc file in the root directory your project. This is similar to a .flowconfig if you use flow types. The .esprintrc file describes which paths to lint and which paths to ignore. You can also override the port to start the background server on. esprint will find the root of your project automatically and lint the whole project. In default mode, esprint will start a background server to watch source files and cache lint results in memory. -

git-peek
git repo to local editor instantly
git peek is the fastest way to open a remote git repository in your local text editor. Use it when you want to browse or search other people's code with your own editor. Pass git peek a git repository or a github link, and it will quickly fetch and open it in your local editor. It stores the repository in a temporary directory and deletes it when you close the editor or git peek. If you don't pass git peek input, it will let you search Github repositories and show trending repositories. If you paste a link to a file on GitHub, it will quickly open the file in your local editor. If you pass it a GitHub repository, it fetches a tarball instead of using git and decompresses it while downloading it (streaming). From unscientific benchmarks, this is about 2x faster than cloning. While downloading & decompressing the tarball, it also downloads the specific file linked to (or the README.md) via JSDelivr's CDN. -

glMatrix
Javascript Matrix and Vector library for High Performance WebGL apps
Javascript has evolved into a language capable of handling realtime 3D graphics, via WebGL, and computationally intensive tasks such as physics simulations. These types of applications demand high performance vector and matrix math, which is something that Javascript doesn't provide by default. glMatrix to the rescue! glMatrix is designed to perform vector and matrix operations stupidly fast! By hand-tuning each function for maximum performance and encouraging efficient usage patterns through API conventions, glMatrix will help you get the most out of your browsers Javascript engine. -

glsl-sandbox
Shader editor and gallery
GLSL Sandbox is an in-browser playground for writing and sharing fragment shaders with instant visual feedback. It provides a minimal editor and a fullscreen WebGL viewport so your shader takes center stage, making it perfect for learning, live-coding, and showcasing visual experiments. The environment injects a small set of uniforms—time, resolution, mouse—so you can animate and interact without boilerplate. A public gallery lets creators browse, fork, and remix shaders, turning the site into a collaborative learning hub. Because everything runs client-side, iteration is fast and portable—just load the page and start typing. It has become a staple tool in the creative-coding community, lowering the barrier to entry for shader art and GPU programming. -

history
Manage session history with JavaScript
The history library lets you easily manage session history anywhere JavaScript runs. A history object abstracts away the differences in various environments and provides a minimal API that lets you manage the history stack, navigate, and persist state between sessions. Development of the current stable release, version 5, happens on the master branch. Please keep in mind that this branch may include some work that has not yet been published as part of an official release. However, since master is always stable, you should feel free to build your own working release straight from master at any time. history is developed and maintained by React Training. If you're interested in learning more about what React can do for your company, please get in touch! -

hotel
A simple process manager for developers
hotel is a developer tool that manages local services behind a friendly dashboard and automatically provisions per-project HTTP proxies. Instead of remembering port numbers and launch commands, you register apps once and then start, stop, or auto-start them from a central UI. The tool sets up a lightweight reverse proxy so each service gets a nice local domain, reducing friction when switching between multiple apps and APIs. Cross-platform support and a simple configuration format make it easy to onboard a team to a shared local workflow. Because hotel can run commands to boot services on demand, laptops stay quieter and lighter until you actually need a process. It’s especially handy in polyglot repos where Node, Python, or Go services otherwise require bespoke scripts and ports. -

image-to-ascii
A Node.js module that converts images to ASCII art
image-to-ascii is a Node.js module that converts raster images into character-based terminal artwork. Input can come from a local file, remote URL, or in-memory Buffer. The converter maps pixel brightness to a configurable sequence of ASCII characters. It can preserve the original colors through ANSI foreground or background styles or generate plain monochrome output. Options control width, height, screen fitting, aspect ratio, transparency, reversed brightness, and custom background colors. Developers can receive a final string or work with the underlying pixel matrix through custom processing functions. A companion command-line package and webcam example provide additional ways to use the conversion engine. -

isomorphic-fetch
Isomorphic WHATWG Fetch API, for Node and Browserify
Fetch for node and Browserify. Built on top of GitHub's WHATWG Fetch polyfill. For ease-of-maintenance and backward-compatibility reasons, this library will always be a polyfill. As a "safe" alternative, which does not modify the global, consider fetch-ponyfill. The Fetch API is currently not implemented consistently across browsers. This module will enable you to use fetch in your Node code in a cross-browser compliant fashion. The Fetch API is part of the Web platform API defined by the standards bodies WHATWG and W3C. All open source code released by FT Labs is licenced under the MIT licence. Based on the fine work by jxck. -
