How do I manage dependencies in a Node.js project with JavaScript?

Asked on Sep 09, 2025

Answer

In a Node.js project, dependencies are managed using the "package.json" file and the Node Package Manager (NPM). This file lists all the dependencies your project requires.

<!-- BEGIN COPY / PASTE -->
        {
          "name": "my-node-project",
          "version": "1.0.0",
          "description": "A simple Node.js project",
          "main": "index.js",
          "scripts": {
            "start": "node index.js"
          },
          "dependencies": {
            "express": "^4.17.1"
          },
          "devDependencies": {
            "nodemon": "^2.0.7"
          }
        }
        <!-- END COPY / PASTE -->

Additional Comment:

The "dependencies" section lists packages required for your application to run.
The "devDependencies" section lists packages needed only during development.
Use the command "npm install" to install all listed dependencies.
Use "npm install package-name" to add a new dependency and automatically update "package.json".
Use "npm install package-name --save-dev" to add a package to "devDependencies".
