A predictable state container for JavaScript apps that manages global application state with a single store and pure reducers.

A full-stack React framework focused on web standards with nested routes, progressive enhancement, and server-side forms.

A CSS preprocessor syntax (Sassy CSS) that adds variables, nesting, mixins, and functions to standard CSS.

A technique where web pages are rendered on the server and sent as complete HTML to the browser, improving SEO and initial load time.

A type of web worker that acts as a proxy between the browser and network, enabling offline support and push notifications.
