Watch Process

The dev server watches your files and rebuilds on changes.

What's Watched

• web/pages/** — Route components
• web/layouts/** — Layout components
• web/styles/ — CSS files
• Configuration files

How It Works

bun run dev

Starts multiple watchers:

1. Router watcher — Detects page/layout changes
2. Style watcher — Rebuilds CSS
3. Client watcher — Rebuilds client bundle
4. Server watcher — Restarts server on changes

Hot Reload

When you save a file:

1. Dev process detects change
2. Regenerates affected files
3. Browser hot-reloads if possible
4. Falls back to full reload if needed

Manual Regeneration

Force regenerate routes:

bun run generate
