package.json Scripts Reference

Summary

Search all npm lifecycle hooks and script events with execution order and usage examples.

How it works

1. Type a keyword in the search box to filter hooks by name, trigger, or description.
2. Click a category badge to show only hooks in that group (install, publish, test, etc.).
3. Click any row to expand it and see the full description, trigger conditions, and a usage example.
4. Use the "Copy" button to copy the script name or the example snippet to your clipboard.
5. The execution order diagram at the top shows the full lifecycle sequence at a glance.

Use cases

• Find the right lifecycle hook to run build steps before publishing to npm.
• Understand which scripts run automatically vs. which must be called explicitly.
