Axios Get Headers

Posted on  by admin

As a developer, you will be required to work with APIs, whether internal or third party. They are needed to bring different applications and services together to build a well-defined application.

Conclusion

Communicating with APIs effectively is an essential factor in your application’s performance, scalability, and reliability. Over the years, Axios has become the most common and popular HTTP client, and with over 90k stars on GitHub, it has one of the largest developer communities behind it. In this article, we will learn how to make GET requests in Axios.

  • I will demonstrate how you can use Axios GET to make requests to public APIs like The Rick and Morty API and Final Space API, and how you can make concurrent GET requests and handle errors.

What is the Axios GET method?

Node.js and npm installed on your local dev machine. Any code editor of your choice. Axios is a Promise-based HTTP client for the browser and Node.

Error handling in Axios

Let’s break down this definition to understand what Axios does. First, HTTP stands for Hypertext Transfer Protocol.

It is a client-server protocol for fetching resources such as HTML documents. “Client” is the user-agent that acts on behalf of the user, and initiates the requests for resources.

Web browsers such as Google Chrome are a popular example of a client. A Promise-based client returns promises. Axios is isomorphic, which means it can run in the browser and Node.js with the same code.

When used on the server side, it uses Node’s native http module, whereas, on the client side, it uses XMLHttpRequests.

On the client side, Axios also supports protection against XSRF. An HTTP GET request is used to request a specified resource from a server.

These requests do not contain any payload with them, i.e., the request doesn’t have any content. Axios GET is the method to make HTTP GET requests using the Axios library.

In this section, we will create the sample app that uses Axios to fetch data using the GET request.

How to make Axios GET requests with query parameters

To begin, run the following command in the terminal:. The command npm init -y creates a package.json similar to the one below in your project’s folder:. The last command, npm install axios, installs the axios package as a dependency in your project. There will be a new package-lock.json file and a node_modules folder in the project folder.

The package.json file will also update and will look similar to this:. You can also install axios using yarn or bower, like so:.

Next, create a file named index.js where you will write the code to fetch resources using the GET requests. Run the following command in the project’s root to create the index.js file:. Run the following command in your project’s root directory to install nodemon as a dev dependency.

Nodemon is an excellent local development tool that automatically restarts the Node application whenever it detects a file change in the directory:. Modify "scripts" in your package.json, like this:. Your package.json should look like this:.

Run the following command to start your Node application:.

You’ll see the following message in your terminal once it has started:. Update the index.js file to include the following code:.
