How to use gitignore File Builder

What it does

Generate robust .gitignore configuration templates for standard frameworks and projects. It runs entirely in your browser — your input never leaves your device.

Options

Every setting this tool exposes, straight from the code that validates it.

Worked example

Run these settings on the tool page:

• templates: ["node","nextjs"]

You get:

# Generated .gitignore

# === Node.js / npm ===
# logs
logs
*.log
npm-debug.log*
yarn-debug.log*
yarn-error.log*

# dependency directories
node_modules/
jspm_packages/

# IDE files
.eslintcache
.stylelintcache
.prettier-cache

# === Next.js / React ===
# next.js build
.next/
out/
build/

# production
.env.production
.env.local
.env.development.local

# debug
.pnp
.pnp.js

Troubleshooting

• It is slow on very large input. Everything runs in your browser, so speed depends on your device. Very large inputs are best split up, or run through the API where the work happens on our servers.

Automating it

The same logic is available as a REST endpoint, so you can run it from a script, a CI job or your own app.

Bash
curl "https://api.toolsxpo.com/v1/gitignore-builder" \
  -H "Authorization: Bearer $TOOLSXPO_KEY"

It costs 1 credit per successful call. See the full endpoint reference, or try it in the playground.
