    ESLint-plugin-React

    ESLint-plugin-React

    React specific linting rules for ESLint

    Install ESLint either locally or globally. (Note that locally, per project, is strongly preferred). If you installed ESLint globally, you have to install React plugin globally too. Otherwise, install it locally. Use our preset to get reasonable defaults. If you are using the new JSX transform from React 17, extend react/jsx-runtime in your eslint config to disable the relevant rules. You should also specify settings that will be shared across all the plugin rules. If you do not use a preset you will need to specify individual rules and add extra configuration. This plugin exports a recommended configuration that enforces React good practices. This plugin also exports an all configuration that includes every available rule. This pairs well with the eslint:all rule. These configurations will import eslint-plugin-react and enable JSX in parser options.

    Ember Table

    Ember Table

    An addon to support large data sets

    Ember Table is a power table made for users who need a full-fledged, fully-customizable table component for their apps. It is built to be flexible, scalable, and ergonomic for day-to-day use. Unlike other table components, Ember Table seeks to provide as many common table features as it can without sacrificing flexibility or composability. You can still use standard component idioms to customize, extend, and build on top of Ember Table at every level, ensuring that it never gets in your way or prevents you from doing what you want. You can use the block form of the table to customize its template. The component structure matches that of actual HTML tables, and allows you to customize it at any level. You can use these values to customize cell in many ways.

    Evercookie

    Evercookie

    Produces persistent, respawning "super" cookies in a browser

    Evercookie is a JavaScript research project that demonstrates extremely persistent browser tracking methods. It stores identifying data across multiple browser storage mechanisms so the identifier can be recreated if only some storage locations are cleared. The project was originally useful for showing how difficult it could be for users to fully remove tracking data from older browser environments. It is now most valuable as a privacy and security education tool rather than a recommended modern tracking library. evercookie helps developers, researchers, and privacy advocates understand why browser storage controls, cache clearing, and tracking protections matter. Its main value is exposing the risks of redundant client-side persistence and encouraging better privacy-respecting design.

    Extension Boilerplate

    Extension Boilerplate

    A template for building cross browser extensions for Chrome

    Now that Firefox supports WebExtensions, it has become a lot easier to build browser extensions/addons for multiple browsers without duplicating the codebase. This project serves as a sensible starting point to help you get started. A foundation for creating browser extensions for Chrome, Opera & Firefox. Your changes to CSS, HTML & JS files will be relayed instantly without having to manually reload the extension. This ends up saving a lot of time and improving the developer experience. This comes with a gulp-based workflow that converts modern ES6 JavaScript and SCSS to JS/CSS. Scripts are transpired using Babel and bundled using Browserify. Source maps are available for both JS and SCSS. A .sketch file is included in the resources directory. This has all the icons and promo images that will be needed while uploading the extensions to the app stores.

    Fetch

    A window.fetch JavaScript polyfill

    Fetch is a window.fetch polyfill, a Promise-based mechanism for programmatically making web requests in the browser. It is a viable replacement for most uses of XMLHttpRequest in traditional web applications, since it implements a subset of the standard Fetch specification. It is compatible with most popular browsers, however modern versions of browsers like Chrome, Firefox, Microsoft Edge, and Safari already have native implementations of window.fetch, hence the code from this polyfill will not have any effect on those browsers. It is also important to note that not all Fetch standard options are supported in this polyfill, and it is only meant for web browsers, not for Node.js environments.
