A React hook plugin for Axios. Lightweight, cancelable and less change.
npm i axios @axios-use/react
import { useResource } from "@axios-use/react";
function Profile({ userId }) {
const [{ data, error, isLoading }] = useResource((id) => ({ url: `/user/${id}` }), [userId]);
if (error) return <div>failed to load</div>;
if (isLoading) return <div>loading...</div>;
return <div>hello {data.name}!</div>;
}
import { useRequest, useResource } from "@axios-use/react";
import axios from "axios";
import { RequestProvider } from "@axios-use/react";
// custom Axios instance. https://github.com/axios/axios#creating-an-instance
const axiosInstance = axios.create({
baseURL: "https://example.com/",
});
ReactDOM.render(
// custom instance
<RequestProvider instance={axiosInstance}>
<App />
</RequestProvider>,
document.getElementById("root"),
);

// js
const [{ data, error, isLoading }, fetch, refresh] = useResource((id) => ({
url: `/user/${id}`,
method: "GET",
}));
// tsx
const [reqState, fetch, refresh] = useResource((id: string) =>
// response.data: Result. AxiosResponse<Result>
request<Result>({
url: `/user/${id}`,
method: "GET",
}),
);
interface ReqState {
// Result
data?: Payload<TRequest>;
// axios response
response?: AxiosResponse;
// normalized error
error?: RequestError<Payload<TRequest>>;
isLoading: boolean;
cancel: Canceler;
}
// `options.filter` will not be called
type Fetch = (...args: Parameters<TRequest>) => Canceler;
// 1. Same as `fetch`. But no parameters required. Inherit `useResource` parameters
// 2. Will call `options.filter`
type Refresh = () => Canceler | undefined;
The request can also be triggered passing its arguments as dependencies to the useResource hook.
const [userId, setUserId] = useState();
const [reqState] = useResource(
(id) => ({
url: `/user/${id}`,
method: "GET",
}),
[userId],
);
// no parameters
const [reqState] = useResource(
() => ({
url: "/users/",
method: "GET",
}),
[],
);
// conditional
const [reqState, request] = useResource(
(id) => ({
url: `/user/${id}`,
method: "GET",
}),
[userId],
{
filter: (id) => id !== "12345",
},
);
request("12345"); // custom request is still useful
// options: onCompleted, onError
const [reqState] = useResource(
() => ({
url: "/users/",
method: "GET",
}),
[],
{
onCompleted: (data, response) => console.info(data, response),
onError: (err) => console.info(err),
},
);

The request
function allows you to define the response type coming from it. It also helps with creating a good pattern on defining your API calls and the expected results. It's just an identity function that accepts the request config and returns it. Both useRequest
and useResource
extract the expected and annotated type definition and resolve it on the response.data
field.
const api = {
getUsers: () => {
return request<Users>({
url: "/users",
method: "GET",
});
},
getUserInfo: (userId: string) => {
return request<UserInfo>({
url: `/users/${userId}`,
method: "GET",
});
},
};
You can also use these request
functions directly in axios
.
const usersRes = await axios(api.getUsers());
const userRes = await axios(api.getUserInfo("ID001"));
custom response type. (if you change the response's return value. like axios.interceptors.response)
import { request, _request } from "@axios-use/react";
const [reqState] = useResource(() => request<DataType>({ url: `/users` }), []);
// AxiosResponse<DataType>
reqState.response;
// DataType
reqState.data;
// custom response type
const [reqState] = useResource(() => _request<MyWrapper<DataType>>({ url: `/users` }), []);
// MyWrapper<DataType>
reqState.response;
// MyWrapper<DataType>["data"]. maybe `undefined` type.
reqState.data;
The createRequestError
normalizes the error response. This function is used internally as well. The isCancel
flag is returned, so you don't have to call axios.isCancel later on the promise catch block.
interface RequestError<T> {
data?: T;
message: string;
code?: string | number;
isCancel: boolean;
original: AxiosError<T>;
}
