Rule Cascade
LearnUse it in your language

Install

Install Rule Cascade in your language: the libraries from the source, the command and the WebAssembly module from the signed downloads.

Pick your language once in the switcher below; every lesson of this track remembers it. Each tab has the same four parts: what to do, the code, the command that runs it, and the output that command printed when this site was built. The libraries install from a checkout of the source; the command and the WebAssembly module are signed downloads.

What to do. Install @rules-cascade/core from a checkout of the source. The browser entry point and the React hook need no other dependency.

The code.

The library is not published to a package registry yet. Until it is, use the signed rcas command or rcas.wasm over the engine protocol: download and verify them, then follow the Command tab.

Run it.

Run it
npm ci && npm run build      # at the repository root, once
npm run dev -w rule-cascade-example-frontend-react

The output.

The example form opens at the address Vite prints. You can also run the TypeScript engine in this page's playground:
