PostCSS is a tool for transforming styles with JS plugins. These plugins can do a great number of things: transpile future CSS syntax, lint your CSS, support variables and mixins, and so much more.

The API can then be used by plugins to do a lot of useful things. With PostCSS, you can increase code readability by adding vendor prefixes to CSS rules; convert modern CSS so it's understood by more browsers; and avoid errors in your CSS via stylelint, a modern CSS linter. PostCSS currently has over 200 plugins, and is being used by industry leaders worldwide. -

Sorry, but there is no way around it since Mozilla decided to adopt WebExtensions as the only extension type and WebExtensions are extremely limited in what they can do. -

BetterScroll
Inspired by iscroll, supports more features and has better performance
BetterScroll is a plugin which is aimed at solving scrolling circumstances on the mobile side (PC supported already). The core is inspired by the implementation of iscroll (opens new window), so the APIs of BetterScroll are compatible with iscroll on the whole. What's more, BetterScroll also extends some features and optimizes for performance based on iscroll. BetterScroll is implemented with plain JavaScript, which means it's dependency free. BetterScroll provides a class whose first parameter is a plain DOM object when instantiated. Certainly, BetterScroll inside would try to use querySelector to get the DOM object. In BetterScroll 2.X, we split the 1.X-coupled feature into the plugin to achieve on-demand loading and reduce the volume of the package. Therefore, @better-scroll/core only provides the most core scrolling capabilities. If you want to implement the pull-up load, pull-down refresh function, you need to use the corresponding [plugin] (/en-US/plugins). -

Conquer Of Completion
Nodejs extension host for vim & neovim, load extensions like VSCode
Configuration is required to make coc.nvim easier to work with, since it doesn't change your key-mappings or Vim options. This is done as much as possible to avoid conflict with your other plugins. Some Vim plugins could change key mappings. Please use commands like verbose imap <tab> to make sure that your keymap has taken effect. Different plug-ins of VSCode provide many configuration items, most of which are used by the server, but some are used by the client. If you do not use plug-ins, you need to make different adaptations to specific servers in the code. At present, most vim LSP plug-ins only support The configuration used by the server. Some functions require the client to do some specific extensions. For example, the jdt.ls of java requires the client to support the uri starting with jdt. When using the coc-java plug-in, users only need to install the plug-in without manual configuration. -

Mitt
Tiny 200 byte functional event emitter / pubsub
Mitt was made for the browser, but works in any JavaScript runtime. It has no dependencies and supports IE9+. This project uses node and npm. Go check them out if you don't have them locally installed. Then with a module bundler like rollup or webpack, use as you would anything else. The UMD build is also available on unpkg. Set "strict": true in your tsconfig.json to get improved type inference for mitt instance methods. Alternatively, you can use the provided Emitter type. Remove an event handler for the given type. If handler is omitted, all handlers of the given type are removed. Invoke all handlers for the given type. If present, '*' handlers are invoked after type-matched handlers.
