In this series, you will go through exercises to learn the basics of how to code in Node.js, gaining powerful tools for back-end and full stack development in the process.
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. In this tutorial, you will manage packages with npm, first keeping track of modules with the package.json file, and then using the npm CLI tool to list your package dependencies, update your packages, uninstall your packages, and perform an audit to find security flaws in your packages.
Testing is an integral part of software development. With the right test setup, this process can be automated, saving a lot of time. In this article, you’ll write tests for a Node.js TODO list module. You will set up and use the Mocha test framework to structure a series of integration tests. Then you’ll use the Node.js assert module to create the tests themselves. Finally, you will try out testing with asynchronous code, and use hooks to prepare your test fixtures and environments.
In this article, you will use a debugger to debug some sample Node.js applications. You will first debug code using the built-in Node.js debugger tool, setting up watchers and breakpoints so you can find the root cause of a bug. You will then use Google Chrome DevTools as a Graphical User Interface (GUI) alternative to the command line Node.js debugger.
