Git Ignore Generator

What this tool does

The Git Ignore Generator builds a `.gitignore` file by combining templates for the stacks and tools you choose. It helps you exclude build artifacts, editor files, and OS metadata from your repository so only source code and essential configuration get committed.

When to use this tool

Use it when starting a new project, adding a new framework, or cleaning up an existing repo that is tracking generated files. It is also handy before sharing a repo with teammates so you can align on what should be ignored. For a full environment cleanup, pair this with Env File Linter to keep secrets and configuration organized.

How it works

The tool fetches official ignore templates for the selected stacks, merges them, and outputs a single `.gitignore` file in your browser. You can also add custom template names to cover niche tools. The output can be copied or downloaded and placed at the root of your repository.

Example use case

You are bootstrapping a React app on macOS with VS Code and Docker. Select React, Node, macOS, VS Code, and Docker, then generate the file. Add the output to your repo before the first commit to avoid tracking `node_modules`, build output, and editor settings.

Use cases

• Bootstrap a new repository with a clean .gitignore file.
• Add a new framework to an existing ignore list.
• Standardize ignore rules across multiple team repos.

Notes & limitations

Templates provide a strong baseline, but every project is different. Review the output to ensure you are not ignoring important configuration or migration files. This tool does not scan your repo; it only generates a file based on the selections you choose. Keep your `.gitignore` updated as your stack evolves.

If your build system creates artifacts in custom folders, add those paths manually after generating the file. It is also common to maintain a global ignore file for editor or OS noise, which keeps project-level `.gitignore` files smaller and easier to review.
