Gitignore Generator

Generate a .gitignore file with rules for popular languages, frameworks, and tools.

Features

Choose common project stacks
Combine rules from multiple technologies
Copy or download the generated file

How to use it

Select the technologies used by your project.
Review the generated ignore rules.
Copy or download the result as a .gitignore file.

Example and use cases

Create a .gitignore for a Next.js project to keep build output and local environment files out of Git.

Useful when starting a repository or adding ignore rules for a new language, framework, or development tool.

.gitignore

What is a .gitignore file?

A .gitignore file tells Git which files and directories should not be tracked in a repository. It is commonly used to exclude dependencies, build output, logs, operating-system files, IDE settings, caches and local environment configuration.

For example, a Node.js application normally should not commit the node_modules/ directory because dependencies can be installed from package.json and package-lock.json.

node_modules/
.env
dist/
*.log

Why use .gitignore?

Protect secrets

Keep local environment files and other sensitive configuration out of Git.

Reduce repository size

Avoid committing dependencies, build artifacts and generated files.

Cleaner repositories

Keep temporary files, logs and editor-specific files out of source control.

Better collaboration

Prevent machine-specific files from appearing as unnecessary Git changes.

Common .gitignore Rules

Pattern	Purpose
`node_modules/`	Node.js dependencies
`.env`	Local environment variables
`dist/`	Generated production builds
`.next/`	Next.js generated files
`*.log`	Log files
`coverage/`	Test coverage output
`.DS_Store`	macOS metadata
`Thumbs.db`	Windows thumbnail cache

How to use the generated .gitignore

1. Generate the file by selecting the technologies used by your project.
2. Download .gitignore or copy the generated content.
3. Place it in your project root, normally beside your package.json or main source directory.
4. Check Git status to verify that unwanted files are no longer shown as untracked.

git status
git add .
git commit -m "Initial commit"

Should .env be added to .gitignore?

In most application projects, local .env files containing secrets or environment-specific values should not be committed to a public repository. Instead, provide a safe example file such as .env.example containing only the names of required variables.

Keep private

.env
.env.local

Safe template

.env.example
MONGO_URI=
JWT_SECRET=
API_KEY=

Gitignore for MERN Projects

MERN applications commonly contain both frontend and backend generated files. A practical .gitignore can exclude Node dependencies, environment variables, build directories, logs and framework-specific output.

node_modules/
.env
.env.local
dist/
build/
.next/
coverage/
*.log

Important Git Security Tip

A .gitignore file prevents untracked files from being added normally, but it does not remove a secret that has already been committed to Git history. If a secret was exposed, revoke or rotate it immediately and clean the repository history when necessary.

Frequently Asked Questions

What is a .gitignore generator?+

A .gitignore generator creates Git ignore rules based on your programming language, framework, operating system and development tools.

Should node_modules be committed?+

Normally no. Node.js dependencies should generally be excluded with node_modules/ and restored using the project's package manager.

Should .env be in .gitignore?+

Yes, when it contains local secrets, credentials or environment-specific configuration. Use .env.example for safe configuration documentation.

Can I use multiple technologies?+

Yes. Select multiple technologies and this generator combines their rules into one .gitignore file while removing duplicate entries.

Can I add custom Git ignore rules?+

Yes. Enter one custom pattern per line in the Custom Ignore Rules field.

Does .gitignore remove files already tracked by Git?+

No. Gitignore mainly affects untracked files. A file that is already tracked may need to be removed from the Git index separately.

Where should .gitignore be placed?+

For most projects, place .gitignore in the repository root directory.

Frequently asked questions

Does a .gitignore remove files already tracked by Git?

No. It prevents matching untracked files from being added; files already tracked must be removed from the index separately.
