What is a .gitignore file?

A .gitignore file tells Git which files and directories to exclude from version control. Entries specify patterns — like node_modules/, *.log, or .env — and Git ignores matching files when staging changes. This prevents dependency folders, build artifacts, and sensitive files from being committed.

Should I commit my .gitignore file?

Yes. The .gitignore file should be committed to the repository so all team members and CI/CD systems use the same exclusion rules. It is a project configuration file, not a local preference.

What is the difference between .gitignore and .gitignore_global?

.gitignore in a repository applies to that project only. .gitignore_global (or ~/.config/git/ignore) is a personal global gitignore that applies to all your repositories. Use the global file for personal IDE or OS-specific files (.DS_Store, Thumbs.db, .idea/), so they do not pollute team .gitignore files.

How do I ignore a file that is already tracked by Git?

Adding a file to .gitignore does not untrack it if Git is already tracking it. Run git rm --cached filename to stop tracking it without deleting the local file, then commit the change.

Why is node_modules in .gitignore?

node_modules contains all installed npm packages and can be hundreds of megabytes with thousands of files. It should never be committed because it can be fully reconstructed by running npm install using the committed package.json and package-lock.json.

What is Gitignore Generator?

The .gitignore Generator on AiTechWorlds creates comprehensive, ready-to-use .gitignore files for any combination of languages, frameworks, editors, and operating systems. A correct .gitignore is essential for every project — it prevents node_modules, build artifacts, environment files, IDE settings, and OS metadata from being accidentally committed to your repository. Creating one from scratch or combining multiple templates manually is tedious. This tool aggregates gitignore templates from the authoritative github/gitignore repository and lets you select as many templates as you need — Node.js + React + VS Code + macOS, for example — and merges them into a single, organized .gitignore file ready to copy into your project root. All generation runs in your browser with no server call. AiTechWorlds built this for developers who want the right .gitignore without searching GitHub or Stack Overflow.
