Anything related to Git in your newly created repository will be stored into this .git directory, all except the .gitignore file.

In this file you can list any file or folder you don’t want to commit to Git.

Its content depends on the kind of project, in a JavaScript project it’s common to have this list in .gitignore:

# build output
dist/

# dependencies
node_modules/

# logs
npm-debug.log*
yarn-debug.log*
yarn-error.log*
pnpm-debug.log*

# environment variables
.env
.env.production

# macOS-specific files
.DS_Store
