This API is build on NODE JS.

Download Node.js

We need to set up a Node.js server. For this purpose, download and install it if you haven't already. you can download it from its's official website, Node.js.

If you don't know what is Node.js here is short description,

2. Open it in your preferred code editor.
3. Run the following commands in the project terminal to create package.JSON file:

npm init -yes

Adding Script

Please update the scripts inside package.JSON file with the following:

"script": {
"start": "node index.js"
}

Install Express Package

Run the following command in your project terminal to install Express in the project.

OR

npm i express

Creating a Route

Create an index.js file. Here we will write a book route

Please use the index.js file, I'm providing for you in this repository.

Code Explanation

1. First, we have imported Express into our file.
2. We created an Express app by calling express().
3. We created a route /book and attached a function to it. When the user makes a GET request to the route, the function will execute.
4. Lastly, we run the Express app on a Port. in this case, it is 5005.

Run the API

Run the following command in your project terminal to run the app.

npm start

Test the API

You can use RapidAPI Client, a VS Code Extension to make a GET request to the API at endpoint: localhost:5005/book
