Understanding of RESTful APIs and the Process of API call

RESTful APIs are a set of standards used to design web services that can be accessed over the HTTP protocol. They provide a uniform way to communicate and interact with different software applications and systems. RESTful APIs use HTTP requests (GET, POST, PUT, DELETE) to interact with the server resources and control their behavior.

My understanding and experience with RESTful APIs include:

  • Designing and implementing RESTful APIs using frameworks like Express.js and Flask.
  • Building client-side applications that consume RESTful APIs using libraries like Axios and Fetch.
  • Working with authentication mechanisms like JWT and OAuth to secure RESTful APIs.

The process of making an API call, handling response data, and displaying it on a webpage involves the following steps:

  1. Instantiating an XMLHttpRequest object or using a library like Axios or Fetch to create an HTTP request.
  2. Sending the HTTP request to the server using the appropriate HTTP method (GET, POST, PUT, DELETE).
  3. Handling the response data by parsing it into a usable format like JSON or XML.
  4. Displaying the response data on a webpage using HTML and CSS.

Here is an example code snippet to retrieve data from a RESTful API using Axios library:

axios.get('https://example.com/api/data')  .then(function (response) {
// handle success console.log(response.data);
}
) .catch(function (error) {
// handle error console.log(error);
}
) .finally(function () {
// always executed }
);

In this code snippet, we are sending a GET request to the server and handling the response data in the success and error callbacks. We can then display the response data on a webpage using HTML and CSS.
