Creating REST API | Simplified

What is an API? An API is an Application Programming Interface that lets you connect two computers, where one computer or application requests the data from the server.

What is a REST API? A REST API or RESTful API is an application programming interface that conforms to the constraints of REST architectural style and allows for interaction with RESTful web services.

Steps:

1. Install Node.js on your machine, using the following link https://nodejs.org/en/

2. create an empty directory and initialize your project by running the following command

   mkdir your-folder-name cd your-folder-name npm init -y

3. The next step is to create an empty JavaScript file and install Express.

   npm install express

4. Initialize the app and start the local server at port 3000.

   Run node index.js to start the server.

5. Now the server is running successfully at port 3000, Next we create an endpoint.

   The get method allows us to create HTTP GET requests.

     It accepts two params:
   
        - The first is path/route.
   
        - The second is a callback function that handles the request to the specified route.
   

6. Suppose we want to display all the users whenever the client requests the "/users" endpoint.

   We have the send method, to return the data from the server to the client

   We will send an array of objects with name and id fields.

7. Run node index.js again and go to the path specified in the code to check the APIs in action! 👍
