Vite is a build tool that aims to provide a faster and leaner development experience for modern web projects. It consists of two major parts:

A dev server that provides rich feature enhancements over native ES modules, for example extremely fast Hot Module Replacement (HMR).

A build command that bundles your code with Rollup, pre-configured to output highly optimized static assets for production.

Nx is a smart and extensible build framework to help you architect, test, and build at any scale — integrating seamlessly with modern technologies and frameworks while providing a distributed graph-based task execution, computation caching, smart rebuilds of affected projects, powerful code generators, editor support, GitHub apps, and more.

Hotwire is an alternative approach to building modern web applications without using much JavaScript by sending HTML instead of JSON over the wire. This makes for fast first-load pages, keeps template rendering on the server, and allows for a simpler, more productive development experience in any programming language, without sacrificing any of the speed or responsiveness associated with a traditional single-page application.

Yjs is a CRDT implementation that exposes its internal data structure as shared types. Shared types are common data types like Map or Array with superpowers: changes are automatically distributed to other peers and merged without merge conflicts.

Yjs is network agnostic (p2p!), supports many existing rich text editors, offline editing, version snapshots, undo/redo and shared cursors. It scales well with an unlimited number of users and is well suited for even large documents.

Ink provides the same component-based UI building experience that React offers in the browser, but for command-line apps. It uses Yoga to build Flexbox layouts in the terminal, so most CSS-like props are available in Ink as well. If you are already familiar with React, you already know Ink.

Snowpack is a better build tool for modern web apps. Snowpack leverages ESM imports in your application to remove all unnecessary bundling work from your dev workflow. The end result is a build tool that starts up instantly and wastes no time rebuilding on every change. See changes reflected in the browser instantly.

Deno is a simple, modern and secure runtime for JavaScript and TypeScript that uses V8 and is built in Rust.

JavaScript Libraries for adding offline support to web apps.

Prettier is an opinionated code formatter. It enforces a consistent style by parsing your code and re-printing it with its own rules that take the maximum line length into account, wrapping code when necessary.
