Built on Chrome’s V8 JavaScript engine, Node.js is a runtime environment that enables JavaScript to run outside the browser. This course will help you learn the fundamentals of Node.js to build portable applications.

You’ll learn about the components and build patterns of Node.js. You’ll also explore the API to learn how to create modules and write code to unique data files. Moreover, you’ll delve into the features and practices of JavaScript and build a REST API using the Express framework from scratch. This will set up authentication tokens with Passport.js and JSON web tokens, and finally build a live trivia game with Socket.IO.

By the end of this course, you’ll be equipped with the extensive knowledge to build rich and comprehensive Node.js applications running on the server with JavaScript.

# Key takeaways

Let’s take a moment to reflect on what we’ve learned in this section:

- Express is minimalistic and provides a lightweight abstraction over the Node.js HTTP modules. It also provides convenience methods for creating routing, views, and middleware.

- Node Package Manager (npm) is the world’s largest JavaScript software registry. It also refers to the command-line interface (CLI) tool for downloading and managing Node.js packages.

- Middleware functions are functions that alter the request (`req`) and response (`res`) objects in the application’s request-response cycle, which is New HTTP Request $\rightarrow$  Middleware Functions $\rightarrow$  Route Handlers.

- REST is a popular architectural convention for structuring and naming APIs using a standardized protocol, such as the HTTP standard. A RESTful API based on the HTTP standard leverages five main HTTP methods (`GET`, `PUT`, `POST`, `PATCH`, and `DELETE`) to retrieve and manipulate data. Each method corresponds to a CRUD operation. A RESTful API can support various data formats, such as XML and JSON.

- The `express.Router` class can be used to create modular route handlers, with each `router` instance being responsible for handling routing for a specific resource, `recipes`, in the backend.
