Preflight Checks

Run comprehensive quality checks before committing or pushing code.

Usage

/demos-preflight

Prerequisites

• Node.js >= 22.18.0 (engines in package.json)
• pnpm (see packageManager in package.json)

Steps

1. Run all checks

• Execute pnpm run preflight which runs:
  • format:check – Verify all files are formatted
  • lint – Check for lint errors (ESLint)
  • spellcheck – Check spelling in code and docs
  • knip – Find unused exports and dependencies
  • docs:links – Verify Markdown links (every .md / .mdx in the repo, including README.md, docs/, .claude/)
  • build – Confirm the production build succeeds (CI and Cloudflare Pages depend on this)

2. Report results

• If all checks pass: Confirm code is ready for commit
• If any check fails: Report specific failures with file locations

3. Suggest fixes

• For formatting issues: Suggest pnpm run format
• For lint errors: Suggest pnpm run lint:fix
• For spelling: Add words to cspell.json or fix typos
• For dead links: Fix URLs or run pnpm run docs:links to see failures
• For unused exports: Remove unused code or add to knip ignore
• For build failures: Check for missing imports, plugin errors, or broken asset references
