How to Create a .gitignore File
Learn the step-by-step process of creating a .gitignore file to prevent sensitive data and build artifacts from being committed.
What is a .gitignore file?
A .gitignore file tells Git which files and directories to ignore in a repository. This keeps your repository clean by excluding dependencies, build artifacts, environment variables, and IDE configurations.
Step 1: Create the file
In the root directory of your project, create a file named exactly .gitignore. Ensure it has a leading dot and no file extension.
Step 2: Add ignore rules
Add paths and patterns you want to ignore. For example, node_modules/ will ignore the node_modules directory, and *.log will ignore all log files.
Step 3: Commit the file
You must commit the .gitignore file to your repository so the ignore rules apply to all collaborators working on the project.
