.gitignore Best Practices

Start early: Create your .gitignore before the first commit. It is much harder to remove tracked files later than to ignore them from the start.
Use negation carefully: Prefix a pattern with ! to re-include a previously ignored file. Example: ignore *.log but keep !important.log.
Global gitignore: For personal IDE and OS files (.DS_Store, .idea/), use a global gitignore (git config --global core.excludesFile) instead of polluting project configs.
Directory trailing slash: Add a trailing / to ignore entire directories (e.g. node_modules/). Without it, Git may match files with that name too.
Check with git status: After updating .gitignore, run git status to verify the right files are excluded. Use git check-ignore -v <file> to debug rules.
Untrack already-committed files: Adding a file to .gitignore does not untrack it. Run git rm --cached <file> first, then commit.

FAQ

What is a .gitignore file and why do I need one?

A .gitignore file tells Git which files and directories to exclude from version control. Without one, you risk committing build artifacts, dependency folders (like node_modules), secret files (.env), OS junk files (.DS_Store), and IDE configurations. This bloats your repository, leaks sensitive data, and causes merge conflicts. Every project should have a .gitignore from day one.

Can I combine multiple .gitignore templates?

Yes. Most real projects use more than one language or tool, so combining templates is standard practice. This generator lets you select multiple templates and automatically merges and deduplicates the patterns into a single .gitignore file organized by section.

Where should I place my .gitignore file?

Place .gitignore in the root of your Git repository. Patterns in the root .gitignore apply to the entire repo. You can also place additional .gitignore files in subdirectories to apply rules only within that directory tree. Git processes them from the root down.

Why are my files still tracked after adding them to .gitignore?

A .gitignore only prevents untracked files from being added. If a file was already committed, adding it to .gitignore will not remove it. You must first run "git rm --cached <file>" to untrack it, then commit the change. After that, the .gitignore rule will apply going forward.

Is my data sent to a server when using this tool?

No. This generator runs entirely in your browser using JavaScript. No data is uploaded, logged, or stored anywhere. Your selections and custom rules never leave your machine.
