📫 Business - jawadrana2015@gmail.com The package.json file in Node.js is a metadata file that contains information about a Node.js project. It's a JSON (JavaScript Object Notation) file that provides essential details such as the project's name, version, dependencies, scripts, author information, and more. Here are the key elements typically found in a package.json file: name: This specifies the name of your Node.js project. It should be unique within the npm registry. version: This indicates the version of your project. It follows the semantic versioning (SemVer) format (e.g., 1.0.0, 1.2.3). description: This is a brief description of your project, providing an overview of its purpose or functionality. main: This specifies the entry point for your Node.js application. By default, it's typically set to index.js or app.js. scripts: This section defines custom scripts that can be executed using npm. Common scripts include start for starting the application, test for running tests, and custom scripts for tasks like building or deploying the project. dependencies: This lists the dependencies required for your project to run. Dependencies are external packages (libraries, frameworks, etc.) that your project relies on. When you run npm install, npm installs these dependencies. devDependencies: Similar to dependencies, devDependencies are packages required for development purposes, such as testing frameworks, build tools, etc. They are not needed for the production version of your application. author: This specifies the author(s) of the project, typically in the format of name and email. license: This indicates the license under which your project is distributed. Common licenses include MIT, Apache, GPL, etc. You can create a package.json file manually by defining these fields, or you can use npm init to interactively generate a package.json file based on your input. The package.json file is crucial for managing dependencies, defining project settings, and automating tasks using npm scripts. #nodejs #javascript #coding #node #backend #nodejstutorial #nodejsdevelopment #tutorial #tutorials #programming #nodeprogramming 0:00 Get Defaults 1:05 Set Defaults 3:19 Delete Defaults
