.gitignore Generatorについて

The .gitignore Generator creates customised .gitignore files by combining pre-built templates for over 30 popular languages, frameworks, IDEs, and operating systems. A .gitignore file tells Git which files and directories to exclude from version control — things like compiled binaries, dependency folders (node_modules, vendor), IDE configuration files, OS metadata (.DS_Store, Thumbs.db), build outputs (dist, build, target), log files, and environment files containing secrets. Committing these files bloats your repository, causes merge conflicts, leaks sensitive configuration, and makes your codebase harder to work with. With this tool you select any combination of templates — for example, Node.js + React + VS Code + macOS — and they are merged into a single, deduplicated .gitignore. You can also add custom rules for project-specific paths and download or copy the result instantly.

.gitignore Generatorの使い方

Browse the template grid and click on each technology relevant to your project — selected templates are highlighted in blue.
Use the category filter buttons (Languages, Frameworks, IDEs, OS) or the search box to find specific templates quickly.
Combine as many templates as you need — for example, Node.js + Next.js + VS Code + macOS covers a typical full-stack web project.
Review the generated .gitignore output that appears below the grid and verify the patterns look correct.
Add project-specific custom patterns in the "Add custom rules" text area at the bottom.
Click Copy or Download to get your .gitignore file and place it in the root of your Git repository.

よくある質問

Should I commit my .gitignore file to the repository?

Yes — always commit .gitignore to your repository. This ensures all contributors on the project (and all CI/CD environments) use the same ignore rules. Without committing it, each developer would need to configure their own ignores locally.

What is the difference between .gitignore and .gitignore_global?

A .gitignore file in a repository applies only to that project. A global .gitignore (~/.gitignore_global) applies to all Git repositories on your machine. IDE files, OS files (.DS_Store), and other personal tooling are better placed in the global file so they do not appear in project-specific .gitignore.

Can I untrack a file that is already committed to Git?

Yes. First add the pattern to .gitignore, then run: git rm --cached <file> to remove it from the index without deleting it locally. Then commit this change. The file will no longer be tracked but still exists on disk.

Why is node_modules/ not ignored by default in some frameworks?

Some framework templates do not include node_modules/ because they assume you are using Yarn PnP or package manager workspaces that handle this differently. Always verify your generated .gitignore includes node_modules/ for standard npm/yarn/pnpm projects.

How do I ignore files globally without affecting the project .gitignore?

Set a global gitignore file with: git config --global core.excludesfile ~/.gitignore_global. Add your personal IDE files, OS files, and local tool configurations there. This keeps project .gitignore files clean and free of personal tooling patterns.
