Writing a REST API with JavaScript

In this tutorial, we'll be learning how to write a REST API using JavaScript. A REST API (also known as Representational State Transfer or RESTful API) is an interface that allows a web client to access and manipulate data stored on a web server. REST APIs are becoming increasingly popular as they allow for easy access to data without the need for any custom scripting or code. We'll be using the fetch() API to make our requests.

The first step is to create an endpoint that will handle our requests. For this tutorial, we'll be using the following endpoint:

https://example.com/api/v1/data

We'll also need to create a function that will handle the requests we make to our endpoint. This function will be responsible for sending the request, parsing the response, and returning the data we need. Here's an example of a basic request handler:

const requestHandler = async (endpoint) => {
  const response = await fetch(endpoint);
  const body = await response.json();
  return body;
};

Now that we have a request handler, we can use it to make requests to our REST API. To do this, we'll need to call the requestHandler() function and pass in the endpoint we want to use. Here's an example of how to make a GET request:

const endpoint = 'https://example.com/api/v1/data';
const data = requestHandler(endpoint);

The data variable will now contain the response from our API. We can then use this data to do whatever we need to do with it. For example, we can display it in a web page or use it to create an interactive application.

In this tutorial, we've seen how to write a REST API using JavaScript. We've created an endpoint and created a request handler to make requests to it. We've also seen how to use the response data to do whatever we need to do with it. Hopefully this tutorial has given you a good understanding of how to create a REST API with JavaScript.
