- It simplifies the process of integrating external code into your projects, reducing the need to write everything from scratch.
- Developers can publish their packages to the NPM registry, making them accessible to others.
Command-Line Interface (CLI):
- NPM is primarily used through its command-line interface, allowing developers to execute various commands for package management.
- Common CLI commands include installing packages, updating packages, removing packages, and managing project dependencies.
- One of NPM’s key functions is managing project dependencies. When you define project dependencies in a “package.json” file, NPM can automatically install and update these dependencies and their transitive dependencies.
- This simplifies the process of managing complex dependency trees.
- NPM enforces version control for packages. Developers can specify version ranges or specific versions of packages in their project’s “package.json” file.
- This helps ensure that projects use compatible package versions and can be easily reproducible.
- NPM allows developers to define and run custom scripts in the “package.json” file. These scripts can automate various development tasks, such as building, testing, and deploying applications.
- NPM includes security features to identify and address known vulnerabilities in packages. Developers can use the “npm audit” command to check for security issues in their dependencies.
- While the public NPM registry is widely used, organizations can set up their private NPM registries to store and share proprietary packages and code internally.
