Notifier for GitHub
Get notified about new GitHub notifications
Checks for new GitHub notifications every minute and shows the number of notifications you have and shows desktop notifications as well. Displays your GitHub notifications unread count. It checks the GitHub Notifications API every minute. Supports GitHub Enterprise and an option to only show the unread count for issues you're participating in. Make sure to add a token to the Options page. Both requested permissions are optional, so you can just decline if you don't want them. The first time you click on the extension icon, it will ask you for access to browser tabs. We need this to know if there is already an opened GitHub notifications page and switch to it if so. If you want to receive desktop notifications, you can enable them on the extension options page. You will then be asked for the notification's permission. -

Privacy Badger
Privacy Badger automatically learns to block invisible trackers
Privacy Badger is a browser extension that stops advertisers and other third-party trackers from secretly tracking where you go and what pages you look at on the web. If an advertiser seems to be tracking you across multiple websites without your permission, Privacy Badger automatically blocks that advertiser from loading any more content in your browser. To the advertiser, it’s like you suddenly disappeared. Privacy Badger was born out of our desire to be able to recommend a single extension that would automatically analyze and block any tracker or ad that violated the principle of user consent; which could function well without any settings, knowledge, or configuration by the user; which is produced by an organization that is unambiguously working for its users rather than for advertisers; and which uses algorithmic methods to decide what is and isn’t tracking. -

Tree Style Tab
Tree Style Tab, Show tabs like a tree.
This extension to Firefox provides the ability to work with tabs as "trees". New tabs opened from the current tab are automatically organized as "children" of the current tab. Such "branches" are easily folded (collapsed) by clicking on the arrow shown in the "parent" tab, so you no longer need to suffer from too many visible tabs. If you want, you can restructure the tree via drag and drop. Such a tree of tabs will behave like a visual browsing history for you. For example, if you see a list of search results for a topic, each search result link will open in new child tab. New tabs opened from these "child" tabs will appear as descendants of their originating tabs. You'll easily dig and dig deeply, without losing your browsing trail - if you want to go back to the original search result, you just have to switch to the "root" tab. Moreover, each tree will reflect a group of tabs on a similar topic. -

Autoprefixer
Parse CSS and add vendor prefixes to CSS rules by Can I Use
PostCSS plugin to parse CSS and add vendor prefixes to CSS rules using values from Can I Use. It is recommended by Google and used in Twitter and Alibaba. Write your CSS rules without vendor prefixes (in fact, forget about them entirely). Autoprefixer will use the data based on current browser popularity and property support to apply prefixes for you. You can try the interactive demo of Autoprefixer. Autoprefixer uses Browserslist, so you can specify the browsers you want to target in your project with queries. It can help you get prefixes for: animations, transition, transform, grid, flex, flexbox and others. You can configure which browsers to generate prefixes for in the distribution. The IE grid layout polyfill is enabled, which is not by default in autoprefixer. Autoprefixer can be used to translate modern CSS Grid syntax into IE 10 and IE 11 syntax, but this polyfill will not work in 100% of cases. This is why it is disabled by default. -

FastClick
Easy-to-use library to remove click delays on browsers with touch UIs
FastClick is a simple, easy-to-use library for eliminating the 300ms delay between a physical tap and the firing of a click event on mobile browsers. The aim is to make your application feel less laggy and more responsive while avoiding any interference with your current logic. FastClick is developed by FT Labs, part of the Financial Times. Note: As of late 2015 most mobile browsers - notably Chrome and Safari - no longer have a 300ms touch delay, so fastclick offers no benefit on newer browsers, and risks introducing bugs into your application. Consider carefully whether you really need to use it. The library has been deployed as part of the FT Web App. FastClick doesn't attach any listeners on desktop browsers. -

FlexSlider
An awesome, fully responsive jQuery slider plugin
Simple, semantic markup. Supported in all major browsers, horizontal/vertical slide and fade animations. Multiple slider support, Callback API, and more. Hardware accelerated touch swipe support. Custom navigation options, compatible with the latest version of jQuery. Display your products in a neatly designed, responsive slideshow within WooCommerce. FlexSlider was built to serve up the best responsive jQuery slider around. I had built a few implementations of responsive sliders on different client projects and noticed that there was a glaring hole for plugin support with the concept. I wanted to build a plugin that would serve the newest of beginners, while providing seasoned developers a tool they could use with confidence. What has come forth is this, FlexSlider. I plan to maintain this plugin and provide support to users implementing FlexSlider into their sites. Responsive web design can be tricky, but I hope that FlexSlider serves to uncomplicate the process, just a little bit. -

browserify
browser-side require() the node.js way
Browserify lets you require('modules') in the browser by bundling up all of your dependencies. Browsers don't have the require method defined, but Node.js does. With Browserify you can write code that uses require in the same way that you would use it in Node. Install the uniq module with npm. Now recursively bundle up all the required modules starting at main.js into a single file called bundle.js with the browserify command. Browserify parses the AST for require() calls to traverse the entire dependency graph of your project. Drop a single <script> tag into your html and you're done! browserify is a tool for compiling node-flavored commonjs modules for the browser. You can use browserify to organize your code and use third-party libraries even if you don't use node itself in any other capacity except for bundling and installing packages with npm. -

vuex-persistedstate
Persist and rehydrate your Vuex state between page reloads
Persist and rehydrate your Vuex state between page reloads. New plugin instances can be created in separate files, but must be imported and added to plugins object in the main Vuex file. It is possible to use vuex-persistedstate with Nuxt.js. It must be included as a NuxtJS plugin. Provides an array of any paths to partially persist the state. If no paths are given, the complete state is persisted. If an empty array is given, no state is persisted. Paths must be specified using dot notation. If using modules, include the module name. If it's not ideal to have the state of the Vuex store inside local storage, one can easily implement the functionality to use cookies for that (or any other you can think of). Any object following the Storage protocol (getItem, setItem, removeItem, etc) could be passed. If you need to use Local Storage (or you want to) but want to prevent attackers from easily inspecting the stored data, you can obfuscate it. -

Babel Plugin Root Import
Add the opportunity to import modules by the root path
Babel plugin to add the opportunity to use import and require with root-based paths. Install with your package manager of choice. Add it to your plugins array in your babel config. For recent react-native versions, add it as a plugin in babel.config.js. You can configure this plugin by changing the string plugin name to a two-item array. Note that this array is nested inside the plugins array. By default, the import will be relative to the working directory of the process running babel. Typically this means you'll have import paths like ~/src/foo.js. You can change the prefix of "./" to e.g. "src" or "src/js" with this config option. By default everything is resolved relative to the current working directory. You can change this with the root config option. To use it effectively, you'll need to configure babel with one of the JavaScript config file variants, rather than JSON. -

Bootstrap Modal
Extends the default Bootstrap Modal class
Extends Bootstrap's native modals to provide additional functionality. Introduces a ModalManager class that operates behind the scenes to handle multiple modals by listening on their events. A single ModalManager is created by default on body and can be accessed through the jQuery plugin interface. Bootstrap-Modal can be used as a replacement for Bootstrap's Modal class or as a patch to the library. If you're using the loading spinner functionality you may also need to change the default template to be compatible in js. Since this plugin was created to solve a lot of the issues with BS2, it still uses the BS2 markup syntax. You can bind the height of the modal body to the window. You can use data-tabindex instead of the default tabindex to specify the tabindex within a modal. The shake animation is included in bootstrap-modal but any animation in animate.css is supported, just include the css file in your project. -

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. -

Navigate the country dropdown by typing a country's name, or using up/down keys. Automatically set the input placeholder to an example number for the selected country. Automatically select the user's current country using an IP lookup. Access the country data to create a separate country dropdown for an address form, and then listen for change events to keep the two dropdowns in sync.

JavaScript Cookie
A simple, lightweight JavaScript API for handling browser cookies
A simple, lightweight JavaScript API for handling cookies which works in all browsers and accepts any character. It is heavily tested, has no dependency, supports ES modules and supports AMD/CommonJS. It is RFC 6265 compliant, has an useful Wiki, and enables custom encoding/decoding. More than 800 bytes gzipped! This project is RFC 6265 compliant. All special characters that are not allowed in the cookie-name or cookie-value are encoded with each one's UTF-8 Hex equivalent using percent-encoding. The only character in cookie-name or cookie-value that is allowed and still encoded is the percent % character, it is escaped in order to interpret percent input as literal. Please note that the default encoding/decoding strategy is meant to be interoperable only between cookies that are read/written by js-cookie. To override the default encoding/decoding strategy you need to use a converter. -

React Refresh Webpack Plugin
A Webpack plugin to enable "Fast Refresh"
An EXPERIMENTAL Webpack plugin to enable "Fast Refresh" (also known as Hot Reloading) for React components. This plugin is not 100% stable. We're hoping to land a v1 release soon, please help us by reporting any issues you've encountered! Ensure that you are using at least the minimum supported versions of this plugin's peer dependencies - older versions, unfortunately, do not contain code to orchestrate "Fast Refresh", and thus cannot be made compatible. For most setups, we recommend integrating using babel-loader. It covers the most use cases and is officially supported by the React team. If you haven't done so, set up your development Webpack configuration for Hot Module Replacement (HMR). This plugin integrates with the most common Webpack HMR solutions to surface errors during development, in the form of an error overlay. -
