    Bundlesize

    Bundlesize

    Keep your bundle size in check

    Add it to your scripts in package.json. Or you can use it with npx from NPM 5.2+. bundlesize accepts an array of files to check. You can give a different file by using the --config flag. If the names of your build files are not predictable, you can use the glob pattern to specify files. This is common if you append a hash to the name or use a tool like create-react-app/nextjs. It will match multiple files if necessary and create a new row for each file. By default, bundlesize gzips your...

    Engine.IO

    Engine.IO

    Transport-based cross-browser bi-directional communication layer

    In most cases, the connection will be established with WebSocket, providing a low-overhead communication channel between the server and the client. Rest assured! In case the WebSocket connection is not possible, it will fall back to HTTP long-polling. And if the connection is lost, the client will automatically try to reconnect. Scale to multiple servers and send events to all connected clients with ease. Socket.IO is a library that enables real-time, bidirectional and event-based...

    Node.js body parsing middleware

    Node.js body parsing middleware. Parse incoming request bodies in a middleware before your handlers, available under the req.body property. As req.body's shape is based on user-controlled input, all properties and values in this object are untrusted and should be validated before trusting. For example, req.body.foo.toString() may fail in multiple ways, for example the foo property may not be there or may not be a string, and toString may not be a function and instead a string or other user...

    two.js

    A renderer agnostic two-dimensional drawing api for the web

    Two.js is a two-dimensional drawing api geared towards modern web browsers. It is renderer agnostic enabling the same api to draw in multiple contexts: svg, canvas, and webgl. Two.js is deeply inspired by flat motion graphics. As a result, two.js aims to make the creation and animation of flat shapes easier and more concise. At its core two.js relies on a scenegraph. This means that when you draw or create an object (a Two.Path or Two.Group), two actually stores and remembers that. After you...

    Relay

    JavaScript framework for building data-driven React applications

    Relay is data-fetching turned declarative. Components declare their data dependencies, without worrying about how to fetch them. Relay guarantees that the data each component needs is fetched and available. This keeps components decoupled and promotes reuse. With Relay, components and their data dependencies can be quickly modified without modifying other parts of the system. That means you won't accidentally break other components as you refactor or make changes to your app. Relay's...
