As long as whatever you're using to fetch data returns a Promise, you can use it in the useQuery hook.

So when fetching data, you can use native fetch, axios, ky, or whatever else!

[00:00] Open the function which executes the HTTP request. In our case, the use query hook is using the fetch API. However, use query requires any API or any library that is capable of returning a promise which resolves once the data is being received. Let's [00:19] install an alternative. Let's type npm install, and we'll install Axios and Kai as just two example libraries, which are going to be replacements for fetch. Let's start with Kai. Replace fetch with Kai. Now we need to import [00:39] the Kai object from Kai package And let's type kai dot get just to make the HTTP method explicit. And now let's open the browser dev tools and head over to the network tab. And after refreshing the page, we will see that the same request, employees page [00:59] 1, has been requested and the data correctly displays. So there is no difference in how React Query works with whatever the API is. So let's also try Axios over here. So const response equals and now we're going to use [01:19] Axios, and we need to import Axios from the Axios package. And we're going to execute again a get request. We'll use what the URL was. And here, we're going to slightly change what is going to be the types over here. [01:39] So this works the same way as the assertion, however, the API is slightly different because we're explicitly passing what is going to be the generic type over here. So what we're going to return is the response dot data. So the response dot data [02:00] is basically the type that we have put over here. And after I move the await to the first line, this one is not needed. So after saving the file and refreshing the page, we can see that now Axius is loading the data. So whatever the API is, as [02:20] long as returns a promise including the response, this query is going to work correctly.
