NPM

What is NPM?

NPM, short for Node Package Manager, is the default package manager for Node.js. Its allows developers to:

• Install Packages: Quickly add external libraries to the project.
• Manage Dependencies: Keep track of versions and updates.
• Share Code: Publish your own modules for the community.

Understanding package.json

At the core of any Node.js project is the package.json file. This file acts as the project’s manifest, containing:

• Metadata: Information about your project such as name, version, and description.
• Dependencies: Lists of packages your project requires to run.
• Scripts: Custom commands to automate tasks like testing, building, or running your app.
• Versioning: Manage semantic versioning for reliable package updates.

Having a well-maintained package.json is essential for consistency, collaboration, and deployment.
