`node --watch` Is the Built-In Restart Loop You Should Try Before Adding Another Dev Dependency
A practical guide to Node's built-in watch mode for restarting local apps on file changes without immediately reaching for another process watcher package.
Why this flag matters: many teams add another dev dependency for auto-restart before checking whether Node can already do enough out of the box.
Modern Node has built-in watch mode. If your local workflow mostly needs automatic restart on file changes, node --watch is often worth trying before you default to another tool.
The simplest form
node --watch server.jsThat tells Node to restart when watched files change. For simple apps, scripts, or internal tools, this can be enough without adding extra packages immediately.
Why this is useful
The point is not that every watcher ecosystem tool is bad. The point is that sometimes the built-in thing is already good enough for:
- prototypes
- internal APIs
- local scripts
- simple services
That can reduce dependency clutter and keep the dev loop easier to reason about.
Final recommendation
If all you need is restart-on-change for a basic Node app, try node --watch first. It may not replace every ecosystem tool, but it often replaces more of them than people expect.
