    WebExt Redux

    WebExt Redux

    A set of utilities for building Redux applications in Web Extensions

    A set of utilities for building Redux applications in web extensions. This package was originally named react-chrome-redux. webext-redux allows you to build your Web Extension like a Redux-powered webapp. The background page holds the Redux store, while Popovers and Content-Scripts act as UI Components, passing actions and state updates between themselves and the background store. At the end of the day, you have a single source of truth (your Redux store) that describes the entire state of your extension. As described in the introduction, there are two pieces to a basic implementation of this package. The dispatches called from UI component will find their way to the background page no problem. The new state from your background page will make sure to find its way back to the UI components. Implement actions whose logic only happens in the background script (we call them aliases).

    YUI 3 - rollout file builder

    Calculate YUI 3 dependencies and build incremental rollout files

    This package produces a single web page displaying a front end to an ANT based build system. The purpose of the package is to automate the process of calculating dependencies and building YUI 3 incremental rollout files. It leverages YUI3 own loader in order to compute the dependencies, so the result is guaranteed to be the same as you get, using a manually crafted configuration of YUI 3 modules. It works for your own and others' gallery modules and for css files too.

    babel-plugin-macros

    babel-plugin-macros

    Allows you to build simple compile-time libraries

    Currently, each babel plugin in the babel ecosystem requires that you configure it individually. This is fine for things like language features but can be a frustrating overhead for libraries that allow for compile-time code transformation as an optimization. babel-plugin-macros defines a standard interface for libraries that want to use compile-time code transformation without requiring the user to add a babel plugin to their build system (other than babel-plugin-macros, which is ideally already in place). There is cpu usage/time overhead; the client needs to run the code to generate these classes every time the page loads. There is code bundle size overhead; the client needs to receive a CSS parser in order to generate these class names, and shipping this makes the amount of js the client needs to parse larger. Eval-ing out code at compile time that will be baked into the runtime code, for instance, to get a list of directories in the filesystem.

    babel-plugin-react-css-modules

    babel-plugin-react-css-modules

    Transforms styleName to className using compile time CSS module

    babel-plugin-react-css-modules is a Babel plugin that enhances the use of CSS Modules in React applications by allowing developers to write cleaner and more intuitive styling code. It automatically maps CSS class names to scoped identifiers, eliminating the need to manually import and reference style objects. The plugin improves developer experience by enabling the use of standard className syntax while still benefiting from the encapsulation provided by CSS Modules. It also supports advanced features such as conditional class names and multiple class assignments. The tool integrates seamlessly into modern React build pipelines, making it compatible with existing workflows. It helps maintain consistent and collision-free styling across large applications. Overall, babel-plugin-react-css-modules simplifies the process of managing scoped styles in React projects.

    clsx

    clsx

    A tiny utility for constructing `className` strings conditionally

    clsx is a tiny JavaScript utility (roughly a few hundred bytes) for constructing className strings conditionally, commonly used in React and other component frameworks. It is intended as a faster and smaller drop-in replacement for the popular classnames package, but with a minimalistic API and implementation. The function accepts any number of arguments in a variety of forms: strings, numbers, arrays, and objects where truthy values indicate which classes to include. It then returns a deduplicated, space-separated class string that can be applied directly to HTML or JSX className attributes. The library is distributed in multiple formats (ESM, CommonJS, and UMD) so it works well in bundlers, Node environments, and direct tags. Because it has zero dependencies and a stable API, it is widely used in both small projects and large production codebases where bundle size is a concern.

    express-session

    express-session

    Simple session middleware for Express

    This is a Node.js module available through the npm registry. Installation is done using the npm install command provided in the instructions. Create a session middleware with the given options. Session data is not saved in the cookie itself, just the session ID. Session data is stored server-side. Since version 1.5.0, the cookie-parser middleware no longer needs to be used for this module to work. This module now directly reads and writes cookies on req/res. Using cookie-parser may result in issues if the secret is not the same between this module and cookie-parser. The default server-side session storage, MemoryStore, is purposely not designed for a production environment. It will leak memory under most conditions, does not scale past a single process, and is meant for debugging and developing.

    mui

    mui

    High-performance framework closest to native APP experience

    The gap between performance and experience has always been the primary reason for mobile app developers to abandon HTML5. The browser’s natural page-cutting white screen, the unbearable turning animation, the jittering of floating elements, and the inability to pull down to refresh smoothly, all of which frustrate HTML5 developers, especially when they get a low-end Android machine to run, and the phone falls. On the other hand, the browser default control styles are few and ugly, making a beautiful control is very troublesome, and there are some simple UI frameworks but low performance. The mui framework effectively solves these problems. This is a framework that can facilitate the development of high-performance apps, and it is also the framework that is closest to the effect of native apps.
