Axios is Mastering JS' offically recommended HTTP client. We occasionally use superagent, but we almost never use the fetch() function.
Choosing the Right HTTP Call Mechanism
The reason is that Axios drastically reduces the amount of boilerplate you need for your average API request. Here's some reasons why:. The syntax for most basic Axios requests is the same in both Node.js and the browser.
Since Node.js does nothave a built-in fetch() function, you need to use a polyfill like node-fetch. And there are several known differences between node-fetch and browser fetch(). One of the most annoying issues with fetch() is that it does not throw an error when the server responds with an HTTP error status, like 404 or 500.
However, fetch()does throw an error if it can't reach the server, so you always need two distinct error handlingpaths with fetch().
The situation is even worse with async/await: every fetch() needs an extra then() to bubble up errors.
Where to make AJAX Requests: componentWillMount vs componentDidMount?
Axios error handling is much easier: just use catch(). Most modern APIs use JSON or form encoding for request bodies.
Axios handles JSON and form encoding automatically, as well as automatically serializing query strings. With all these limitations, the unfortunate reality is that everybody who uses fetch() writes their own wrapper around fetch().
It is extremely difficult to build an app using fetch() directly. Axios lets you go further by providing some framework-like features.
You can use interceptors and instances tocreate your own API wrappers using Axios.
- For example, here's how you can build a Trello API client usinginstances and interceptors:. So Axios not only eliminates a lot of the boilerplate and rough edges of fetch(), and also makes it easier tobuild specific wrappers for different APIs.
- Modified2 years, 8 months ago. I've been a jQuery user since forever. But now I'm building my first API that uses JWT for authentication.
- This said, most tutorials I find online to consume this API with authentication headers use Axios to make these requests. I am already using jQuery on the project, so, I would love to make simple jQuery ajax calls, but I'm not sure if there's any hard drawbacks to using it.
- This would be my jQuery code:. Send the Request. After reading the Axios features, the last one is: Client side support for protecting against XSRF .

Does jQuery ajax not support that? Would I have to do anything extra to make this protection? Is there anything else that makes it worth using another library like Axios instead of jQuery?

I have found (in the past) that Axios is more trouble than it's worth. Simple procedures, like performing A GET request to request a resource listing, altering an item in the listing with a POST/PUT/DELETE request, and then re-requesting the listing (to synchronise the view) causes cached data to be served, meaning the view does not change.
This is just one example. Edit: I'm curently working on a Vue.js project, and I remembered a few more reasons why I stuck with jquery over axios:.
It's worth noting that if you use bootstrap or something similar, you already have jquery included, so why include a second library?
And finally, I use a simple script which converts any standard html form to an ajax submission form simply by adding a couple of classes, and a bootstrap-alert to display errors.
It's intended for use with laravel, and (optionally) Vue.js. It's really handy because it handles styling of the form components to tell the user what is happening. For debugging server side errors you can just remove the "ajax-submit" class from the form and it will revert to standard form submission.
The anciliary operations in the script are most simply implemented using jQuery.
I have put it in a gist here. Hopefully someone will find it useful. I would actually be very interested to see how difficult it is to create an equivalent script using Axios, and excluding jQuery.
Further Edit: I just had to remove Axios from yet another project. It is a PWA app and Axios does not have an option to use the fetch API which is required for use with service workers. I created a gist to replace Axios with fetch here. Maybe it will be of some use to someone. I do not see any explicit support for that in the jQuery $.ajax documentation. That being said, it is something you could do with the beforeSend setting.
Calling APIs using the Fetch API
In the beforeSend you would modify the jqHXR to include your XSRF information. @charlietfl mentioned you can also do this in global ajaxSend() so it is applied to all instances of $.ajax(). This is what axios is doing:.
If you are already using jQuery in your project, and you can handle the XSRF yourself, then use $.ajax().
"Is there anything else that makes it worth using another library like Axios instead of jQuery?" I would say most definitely.
How to Fetch Data from HTTP Servers in React?
A library dedicated to handling http decouples the process from your application framework or presentation library. 22 gold badges1515 silver badges3939 bronze badges. 3939 bronze badges. Throughout this AjAX with React tutorial we will cover different ways to do AJAX in React (Axios, jQuery and the Fetch API).
We'll see by example how to use the browser Fetch API to send an HTTP request (GET and POST) to Reddit and from where you can make AJAX calls in a React component i.e componentDidMount() vs componentWillMount() vs the ES6 class constructor.
We'll learn, with a simple example, how to make AJAX requests or API calls (GET, POST, PUT and DELETE) to fetch, create, update and delete data using React via different mechanisms such as the Axios library, XMLHttpRequest or the modern browser's fetch API.
React is a view library, for building user interfaces or UIs, not a complete framework like, for example, Angular or AngularJS. In MVC architectures, React represents the View part. So if you have used a client side framework before, you will notice the lack of many abstractions such as services to make HTTP calls (equivalent to $http in AngularJS).
So — If you are asking what's the React equivalent for sending AJAX calls? You shouldn't consider this as a weakness of the library because React isn't supposed to handle all the tasks usually handled by frameworks.
The whole purpose of React is to render stateless components (dump components with no data) and statefull components using data from props and state (that's usually fetched from an API server). So how to fetch data from a remote HTTP server?
or how to make API calls? You have a plethora of options, at your disposal, from external libraries to standard browser APIs. All you have to do is to choose the right solution for your needs.
If you like to work with cutting-edge standards, you can use the browser' fetch API. You can also use jQuery, but it's not recommended to include the whole library just for the sake of making API calls.
You can use XMLHttpRequest interface. Let's now see a practical example, using the browser's fetch API.
We'll create a simple React app that sends API calls to the Reddit server to fetch some subreddit posts. So go ahead and create a new React project. I'm using and recommending create-react-app because it saves you from the hassle of configuring WebPack and lets you quickly generate a starter project to build your app.
Passing Data via props
It also provides a global fetch() method that provides an easy, logical way to fetch resources asynchronously across the network. Now let's fetch some data from Reddit. In src/App.js update the code to reflect these changes:.
Using Redux State Manager
Right in the fetchFirst() method, we are sending a GET request to fetch data from'https://www.reddit.com/r/' + url + '.json' using the following code:. The API is simple, the only required argument is the resource's URI.
In our example it's a JSON file but can be any type of resource like an image or other types. Without extra parameters fetch(url) sends a GET HTTP request by default. You can also call the other HTTP methods such as POST, PUT or DELETE by explicitly specifying the method name in the second argument.
