Local composition
Template selection and final file generation stay in the browser until you choose to copy or download the result.
Stack-aware output
Mix language, framework, editor, and OS presets when a repository spans multiple stacks or contributor environments.
Secrets still need review
Preset templates cover common `.env`, cache, and build folders, but you should still audit project-specific secret paths before committing.
Export .gitignore
Generation must finish before export is enabled.

.gitignore Patterns: Keeping Your Repository Clean
Key Takeaways
- .gitignore files specify which files and directories Git should exclude from version control.
- Common ignores include: node_modules/, .env files, build outputs, OS files (.DS_Store), and IDE configs.
- Patterns support wildcards (*), directory matching (/), and negation (!) for flexible file exclusion.
A .gitignore file tells Git which files to intentionally leave untracked. Without proper ignore rules, repositories quickly fill with build artifacts, dependency folders, environment secrets, and OS-generated files that bloat history and potentially leak sensitive information. Each programming ecosystem has well-established .gitignore conventions.

Common Use Cases
New Project Setup
Generate a tailored .gitignore when initializing a new repository for your tech stack.
Security
Prevent sensitive files (.env, credentials, API keys) from being committed to version control.
Repository Hygiene
Exclude build outputs, cache directories, and temporary files to keep the repo lean.
Cross-Platform Teams
Ignore OS-specific files (.DS_Store, Thumbs.db) that vary across team members' machines.
Practical Tips
Use gitignore.io (toptal.com/developers/gitignore) to generate templates for your specific tech stack.
Add .gitignore rules before making your first commit — removing already-tracked files requires extra steps.
Use a global .gitignore (~/.gitignore_global) for personal IDE and OS files to keep project .gitignore clean.
Test your patterns with 'git check-ignore -v filename' to verify which rule is matching each file.
