Axios Get Request

Posted on  by admin

When you’re building a web application, there may come a time when you want to perform a HTTP request to access an external resource.

For instance, suppose you are making a blog. You may want to call an API to retrieve a list of comments to show on each blog post. Axios is a popular JavaScript library you can use to make web requests.

How to make GET requests using Axios

In this guide, we’ll explain how to use axios to make a GET request. We’ll walk through a few examples to showcase how axios works and how you can use it in your code. Axios is a promise-based library that makes it easy to make web requests.

You may be wondering: why should I use axios over one of the many other web request libraries out there?

It’s true that there are other libraries like fetch that you can use to make GET requests, but axios has a number of advantages these libraries don’t have.

How to make Axios GET requests with an API key

Axios supports older browsers, which will allow you to create a more accessible user experience.

Axios also comes with built-in CSRF protection to prevent vulnerabilities.

It also works in Node.js, which makes it great if you’re developing both front-end or back-end web applications.

The options Parameter

Before you make a GET request using axios, you’ll have to install the library.

  • You can do so using the following command:.
  • This command will install axios and save it to your local package.json file.
  • Now you’re ready to start using the axios library.
  • Getting started with axios is simple.
  • To make a web request, all you need to do is specify the URL from which you want to request data and the method you want to use.

Suppose you want to retrieve a list of random facts about cats from thecat-factsAPI.

We could do so using this code:.

This code returns a promise which represents a request that hasn’t been completed yet. In order to retrieve data from this HTTP request, you would use an async/await function like so:.

GET request using axios with async/await

The server responded with a list of cat facts. When we call this function, an HTTP GET request is made to the cat-facts API.

We use an async/await function so our program does not continue until the web request has been completed.

This is because axios returns a promise first. It returns the data from the request it makes after that request has been completed.

What is the Axios GET method?

The axios library comes with a few shorthand commands you can use to make web requests: . axios.delete() . axios.patch() . axios.options() . In this tutorial, we’re going to focus on the axios.get() and methods, which use the same basic syntax as all the other shorthand methods.

In our last example, we used axios to make a GET request.

But, there is a simpler way to make a GET request with axios: using axios.get() .

How to install Axios in a Node.js project

Suppose you want to retrieve a list of cat facts, then count how many have been returned. You could do so using the following code:.

The code generated this response: 225 cat facts were returned.

Let’s break down our code. We have first declared an async function called getCatFacts() in which we make a web request.

How to make Axios GET requests with query parameters

We then use axios.get() to retrieve a list of cat facts from the cat-facts API; “” holds the response objects and request body from our request.

  • Finally, we use the .length attribute to calculate how many cat facts have been returned from our request.
  • We then add this number into the string “cat facts were returned”.
  • When you’re making a GET request, you may need to send a custom header to the web resource to which you are making the request.
  • Suppose you are retrieving data from an API that requires authentication.
  • You may need to specify an authentication header.

To specify a header with an axios request, you can use the following code:.

Installing axios from npm

This code would send the header “header-name” with the value “header-value” to the URL we have specified.

Many APIs allow you to send parameters in a GET request.

For instance, an API may allow you to limit how many responses are returned using a limit parameter.

Specifying a parameter to send with a web request is easy using axios. You can either include the parameter as a query string, or use the params property.

Here’s an example of axios making a web request using query strings to specify a parameter:.

GET request using axios with error handling

Alternatively, you could specify a params property in the axios options using this code:.

Both of these examples send a parameter with the name “date” and the value “2020-05-15” to the specified URL. The syntax for making a POST request is the same as making a GET request.

GET request using axios with set HTTP headers

The difference is you should use the method instead of axios.get() .

Suppose you want to make a post request to an API.

You could do so using this code:. You’re able to specify headers and parameters in the same way as you would to make a GET request.

How to make HEAD requests with Axios

Let’s say you want to send the header “Name” with the value “James” with your POST request.

You could do so using this code: . The axios library is used to make web requests in JavaScript. It can be used on both the front-end using JavaScript or on the back-end using a platform like Node.js.

Unlike other web request libraries, axios has built-in CSRF protection, supports older browsers and uses a promise structure.

Simple GET request using axios

It’s perfect for making web requests. Now you’re ready to start making GET and POST requests using axios like a professional web developer.

One of the most typical things a developer does is make an HTTP call to an API.

An API request can be sent in a variety of ways. We can use a command-line tool like cURL, the browser's native Fetch API, or a package like Axios to accomplish this.

Sending HTTP requests to your API with Axios is a fantastic tool.

Axios is supported by all major browsers. The package can be used for your backend server, loaded via a CDN, or required in your frontend application.

How to Make a Request Using Axios

Axios is a promise-based HTTP client for Node.js and the browser.

Sending asynchronous HTTP queries to REST endpoints and performing CRUD operations is simple using Axios POST request and GET request.

It can be used directly in JavaScript or in conjunction with a library like Vue or React.

When designing dynamic web applications, sending HTTP multiple requests from the Javascript side is almost a requirement.

Axios makes this work easier by offering a user-friendly abstraction over Javascript XMLHttpRequest interface with a variety of functions and configuration options.

If you are using JavaScript, it provides, XMLHttpRequest, a built-in interface for handling HTTP requests.

Customizing Serialization

Sending multiple requests with this interface, on the other hand, is a bit of a pain and necessitates writing a lot of code.

The $.ajax function should be recognizable to anyone who has used JQuery.

It provides a more straightforward and user-friendly abstraction over the XMLHttpRequest interface, allowing us to send HTTP requests with fewer lines of code.

Developers needed a native Javascript way to create HTTP requests as frameworks like JQuery become obsolete in recent years.

Fetch API and Axios are the two most common native Javascript alternatives for sending multiple requests right now. However, Axios GitHub has an advantage over Fetch API because of some of the unique features it offers developers.

Sending Parameters Using axios

We've included a handful of them below. Support for multiple request and response interception.

Efficient Error handling. Client-side support for XSRF (cross-site request forgery) protection.

Response timeout.

Being able to cancel requests. Support for older browsers (Internet Explorer 11).

Automated JSON data translation. Support for upload progress. Developers are increasingly choosing Axios GitHub over Fetch API to send HTTP requests due to its powerful features.

There are several ways to incorporate Axios into your project.


You can use npm:.

Or add to your web page using CDN:.

Sending HTTP requests with Axios is as simple as giving an object to the axios() function that contains all of the configuration options and data.

This Axios tutorial will be very helpful for beginners. Let's look at the configuration options in more detail:.

How to make concurrent requests with Axios

method: The HTTP method through which the request should be sent in.

url: The server's URL to which the request must be sent to.

Error handling in Axios

data: The data specified with this option is sent in the body of the HTTP request in Axios POST requests, PUT, and PATCH.

To learn more about configuration options available with Axios request functions, refer to the official documentation.

In Axios, these are the fundamental methods for making multiple requests.

When we send an HTTP request to a remote server, we get a response with specific information from that server API.

Axios may be used to retrieve this response.
