Catalyst

Catalyst is a React framework for building performant web apps and universal apps for Android and iOS. It provides server-side rendering, route-level data fetching, app shell primitives, styling conventions, and native WebView packaging tools.

Quick Start

Create a new Catalyst app with:

npx create-catalyst-app@latest

Then start the generated app:

cd <your-app>
npm run start

The development server starts at http://localhost:3005.

  • examples/catalyst-core-test: standalone fixture app used to test catalyst-core

Install dependencies and create local docs config before running build/test commands:

npm run setup
