Quickstart

Two walkthroughs from an empty directory to a railroad diagram rendered in the browser. Both use @choo-choo/vanilla plus Vite as a zero-config dev server.

Prerequisites

• Node.js ≥ 20.
• pnpm (≥ 10). npm and yarn work too — swap the commands accordingly.

First Steps

• Hello world: Build a minimal diagram by hand.
• Grammar example: Parse an EBNF source and render a rule from it.
