The first step will be to create and understand the package.json file. In this tutorial, you will manage packages with npm.

The file will keep track of this information automatically while you may change the file directly to update your project’s metadata, you will seldom need to interact with it directly to manage modules.

Scripts that can be run to automate tasks within the projectĪs you create more complex Node.js projects, managing your metadata and dependencies with the package.json file will provide you with more predictable builds, since all external dependencies are kept the same.

All the metadata for a project, such as the author, the license, etc.

All the modules needed for a project and their installed versions.

npm tracks the modules installed in a project with the package.json file, which resides in a project’s directory and contains: It is also commonly used to install a wide range of CLI tools and run project scripts. The Node.js Package Manager (npm) is the default and most popular package manager in the Node.js ecosystem, and is primarily used to install and manage external modules in a Node.js project. A collection of one or more modules is commonly referred to as a package, and these packages are themselves organized by package managers.

Node.js organizes this complexity using modules, which are any single JavaScript files containing functions or objects that can be used by other programs or modules. But as interest grows, larger applications are built, and managing the complexity of the codebase and its dependencies becomes more difficult. Introductionīecause of such features as its speedy Input/Output (I/O) performance and its basis in the well-known JavaScript language, Node.js has quickly become a popular runtime environment for back-end web development.
