.gitignore nodejs

.gitignore file for Node.js:

# Dependency directories
node_modules/

# Optional npm cache directory
.npm

# OS generated files
.DS_Store
Thumbs.db

Explanation: - node_modules/: Ignore the entire node_modules directory, which contains all of the dependencies for the Node.js project. - .npm: Ignore the npm cache directory, which is optional but commonly ignored. - .DS_Store and Thumbs.db: These are operating system generated files on macOS and Windows respectively, which should be ignored in version control.
