.gitignore Generator

Generate a comprehensive .gitignore file covering multi-language projects.

Instructions

When triggered, create a .gitignore file in the project root with the template below. If the project clearly uses only specific languages, you may omit irrelevant sections — but when in doubt, keep everything.

Template

Write the following content to .gitignore:

After Creating

Tell the user:

• Which sections are included
• That .env.example / .env.template are intentionally not ignored (safe to commit as templates)
• Suggest they review the lock file section (yarn.lock, package-lock.json, pnpm-lock.yaml) — typically one should be committed, not ignored
