.gitignore Generator

A .gitignore file tells Git which files or directories to ignore in a project. This prevents large dependencies or sensitive secrets from being pushed to the remote repository.

Folders like node_modules contain thousands of third-party files that can be easily re-installed using package managers. Storing them in Git makes the repository unnecessarily large.

No, .gitignore only prevents untracked files from being added. If a file is already being tracked by Git, you must manually remove it using git rm --cached.
