What is Axios
Axios is a popular JavaScript library used for making HTTP requests from a web browser or Node.js.
Whether you're building a web app or a server-side application, Axios makes it easy to work with APIs and other HTTP servers.
In this blog, we'll show you how to get started with Axios, from installation to making basic GET and POST requests and handling errors, using async/await syntax.
Setting Up Axios
To start using Axios, you'll need to install it in your project. You can do this using NPM or a CDN.
Here's an example of how to install Axios using NPM:
Once you've installed Axios, you can include it in your HTML or JavaScript code.
Here's an example of how to include Axios in Your Code:
Basic GET Request
Let's make a simple GET request to retrieve data from an API using async/await syntax.
Here's an example of how to make a GET request with Axios using async/await:
We're using the async/await keywords to create an asynchronous function and await for the response from the API before logging the data to the console.
Basic POST Request
Now, let's make a simple POST request to send data.
Here's an example of how to make a POST request with Axios using async/await:
The data we're sending is an object with two properties: firstName and lastName.
If the request is successful, the response data will be logged to the console.
Handing Errors
HTTP requests can sometimes fail, for various reasons such as network errors or server-side errors.
It's important to handle these errors gracefully in your code.
Fortunately, Axios provides several options for handling errors and exceptions.
Here's an example of how to handle a 404 error using async/await
In this example, we're using the if statement to check if the HTTP response status is 404, which indicates that the requested data was not found.
If the status is 404, we're logging a custom error message to the console.
If the status is anything else, we're logging the original error message to the console.
Conclusion
Axios is a powerful JavaScript library that makes it easy to work with HTTP requests in your web apps or Node.js projects.
Whether you need to make a simple GET request or a more complex POST request, Axios provides an intuitive and flexible API that you can use with async/await syntax to create robust and reliable applications.
With this introduction to Axios and async/await, you're well on your way to becoming a skilled JavaScript developer.
