About .gitignore
Produce a correct .gitignore for your stack in one click — dependencies, builds, secrets, OS junk.
Pick the primary stack and optionally a second for monorepos. The generator merges curated rule sets — dependency folders, build output, environment files with secrets, logs, coverage, and OS droppings — deduplicated and sectioned.
The .env rule matters most: secrets committed once live forever in history. Everything runs in your browser.
Where it is used
New repos, stack migrations, polyglot monorepos, and teaching what must never be committed.

- Primary Stack — enter the value.

Frequently Asked Questions
- Already committed node_modules?
- Add the rule, then run git rm -r --cached node_modules and commit. The rule only stops future tracking.
- One gitignore per repo or per folder?
- One at root covers everything below. Nested files only for genuinely different rules (e.g. docs/ allowing built HTML).
- Should .env.example be ignored?
- No — commit the example (keys without values) so teammates know what to configure. Ignore only real .env files.
