Turn any datasource into an internal app in minutes. Appsmith lets you drag-and-drop UI components to build pages, connect to any API, database or GraphQL source and write logic with JavaScript objects.

Expo is a framework and a platform for universal React applications. It is a set of tools and services built around React Native and native platforms that help you develop, build, deploy, and quickly iterate on iOS, Android, and web apps from the same JavaScript/TypeScript codebase.

Mermaid is a Javascript based diagramming and charting tool that uses Markdown-inspired text definitions and a renderer to create and modify complex diagrams. The main purpose of Mermaid is to help documentation catch up with development.

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.

Quicktype generates types and helper code for reading JSON in C#, Swift, JavaScript, Flow, Python, TypeScript, Go, Rust, Objective-C, Kotlin, C++ and more. Customize online with advanced options, or download a command-line tool.

Tina is an open-source site editing toolkit for React-based sites like Next.js & Gatsby to build content management directly into your website.

A React-powered node editor and runtime engine. Build apps that are resilient to changing requirements by modeling your business logic as a JSON graph. Flume provides a sleek UI for creating and editing these graphs.

Tauri is a framework for building tiny, blazing fast binaries for all major desktop platforms. Developers can integrate any front-end framework that compiles to HTML, JS and CSS for building their user interface. The backend of the application is a rust-sourced binary with an API that the front-end can interact with.

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.

Svelte is a radical new approach to building user interfaces. Whereas traditional frameworks like React and Vue do the bulk of their work in the browser, Svelte shifts that work into a compile step that happens when you build your app.

Instead of using techniques like virtual DOM diffing, Svelte writes code that surgically updates the DOM when the state of your app changes.

Easy control over your dark mode in a web environment

meSpeak.js (modulary enhanced speak.js) is a 100% client-side JavaScript text-to-speech library

Gatsby is a modern framework for blazing fast websites, made with React and GraphQL.
