BetaSu/just-react

freeCodeCamp is a free, self-paced curriculum for learning to code, published as open source at freeCodeCamp/freeCodeCamp. It's a 501(c)(3) nonprofit funded by donor support, structured around six certifications in its Full-Stack Developer Curriculum, each gated by required projects instead of open-book quizzes. The repository also carries beta language certifications for developers, interview-prep resources, and the code that runs the live freecodecamp.org platform.

Next.js is a React framework from Vercel for building full-stack web applications, with file-based routing, server rendering, and static generation built in. Instead of wiring a router, bundler, and rendering strategy onto plain React yourself, you get those decisions made for you and pick a rendering mode per route.

Ant Design is an open-source React UI library and design language maintained at ant-design/ant-design on GitHub. Its README describes pre-built TypeScript components, a CSS-in-JS theme-customization system, and locale support spanning dozens of languages, aimed at enterprise-class web apps. The project is released under the MIT license.

Storybook is a frontend workshop maintained at storybookjs/storybook. It renders UI components and pages in isolation from your main application. Core renderers include React, Angular, Vue 3, Web Components, HTML, Ember, Svelte, and Preact, plus React Native and community support for Qwik and SolidJS. It's released under the MIT license.
