Examples

Three worked projects. Each is a complete project: file layout, source, build commands, deploy notes.

• Frontend — todo list with reactive DOM updates. Vite + vanilla DOM. Output is static.
• Backend — WebSocket server with per-connection signals and an SSE stats endpoint. Node 18+.
• Edge — HTTP handler with per-request signal scope and a Durable Object rate limiter. Cloudflare Workers.

Common setup

All three projects use the same setup:

# Install the @para/* packages your code uses, e.g.:
npm install @para/signals @para/parallel @para/pipeline

…plus a one-line bundler alias mapping para:* to @para/* (see the install guide for the per-bundler snippets), and parabun build to transpile .pts files.

Build targets

Project	parabun build target	Bundler
