Frequently Asked Questions

package.json is a JSON file that sits at the root of a Node.js project. It holds metadata about the project, such as name, version, dependencies, scripts, and more. It's the heart of any npm package or Node.js application.

You can create one manually by running npm init in your terminal, which asks questions. Alternatively, use this online generator to build and customize the JSON interactively, then copy the output to your project.

The two mandatory fields are name and version. The name must be lowercase, URL-safe, and unique if published to npm. The version must follow Semantic Versioning (e.g., 1.0.0). All other fields are optional but recommended.

Semantic Versioning (SemVer) is a versioning scheme with three numbers: MAJOR.MINOR.PATCH. Increment MAJOR for breaking changes, MINOR for new features (backward-compatible), and PATCH for bug fixes. Example: 2.1.3.

Yes! Under the "Scripts" section you can add any key-value pair. Common scripts include "start", "build", "test", and "lint". They can be executed with npm run <script-name>.

Dependencies are packages required for the application to run in production. DevDependencies are only needed during development (e.g., testing frameworks, build tools). Use npm install --save-dev for dev dependencies.
