This hook can be used to perform queries to an endpoint. Allows easy management of operations and query status.
It requires an Axios client. This library already provides the generateApiClient function which returns a client with a variable base url and an interceptor to send an authentication header. You may also create an axios client by your own.
Install the library with npm install @vai-js-software/use-query.
At the upper level of the application you should also insert the ApiProvider component which requires an apiClient prop. It should be an Axios client which you can create by your own or use generateApiClient to generate one.
Here is an example:
import { generateApiClient, ApiProvider } from "@vai-js-software/use-query";
...
const apiClient = generateApiClient({
baseUrl: "https://my.api.com/api/v1",
authorizationHeader: "Authorization",
authorizationPrefix: "Bearer "
})
...
root.render(
<React.StrictMode>
<ApiProvider apiClient={apiClient}>
<App />
</ApiProvider>
</React.StrictMode >
);This function returns an Axios client with the possibility to set a baseUrl, and an authorization header. It gets the authorization token from localStorage or sessionStorage with the key token.
| Parameter | Type | Default | Description |
|---|---|---|---|
| baseUrl | string | Axios base url | |
| timeout | number | 5000 | Default timeout (milliseconds) |
| authorizationHeader | string | "Authorization" | Authorization header name |
| authorizationPrefix | string | "Bearer " | The authorization header prefix, for example Authorization: Bearer your_token_from_localstorage
|
| localStorageKey | string | "token" | Local storage key that contains the authentication token |
This is what generateApiClient generates, you can use it as a base to create your own api client.
const apiClient = axios.create({
baseURL: baseUrl,
timeout: 5000,
headers: {
"Content-Type": "application/json",
Accept: "application/json",
},
});
apiClient.interceptors.request.use(
function (config) {
config.headers = config.headers || {};
const token =
localStorage.getItem("token") || sessionStorage.getItem("token");
if (token) {
config.headers[authorizationHeader] = `${authorizationPrefix}${token}`;
}
config.headers["Content-Type"] = "application/json";
config.headers["Accept"] = "application/json";
return config;
},
function (error) {
return Promise.reject(error);
}
);
apiClient.interceptors.response.use(
function (response) {
return response;
},
function (error) {
return Promise.reject(error);
}
);This function returns an Axios client with the possibility to set a baseUrl, and an authorization header. It gets the authorization token from localStorage or sessionStorage with the key token.
| Parameter | Type | Default | Description |
|---|---|---|---|
| baseUrl | string | Axios base url | |
| timeout | number | 5000 | Default timeout (milliseconds) |
| authorizationHeader | string | "Authorization" | Authorization header name |
| authorizationPrefix | string | "Bearer " | The authorization header prefix, for example Authorization: Bearer your_token_from_localstorage
|
| accessTokenLocalStorageKey | string | "accessToken" | Local storage key that contains the access token |
| refreshTokenLocalStorageKey | string | "refreshToken" | Local storage key that contains the refresh token |
| refreshTokenFunction | function | An asyncronous function that receives the old access token and refresh token and returns [newAccessToken, newRefreshToken] |
This hook performs only one query, if you have to perform multiple queries in parallel you can call multiple times useQuery or use useMultipleQueries as described below.
| Parameter | Type | Default | Description |
|---|---|---|---|
| url | string | Endpoint url | |
| method | string | 'GET' | Request method (GET, POST...) |
| executeImmediately | boolean | false | Sets whether the call should be executed when the component is created or wait for the call to executeQuery()
|
| onSuccess | (response) => void |
() => { } |
Function executed after a successful query |
| onUnauthorized | (error) => void |
undefined | Function executed after an unsuccessful query if the response code is 401 (optional, see onError). The default function is the one defined in the ApiProvider if it is not specified in useQuery. To disable the default one and not use an onUnauthorized set onUnauthorized=null
|
| onError | (error) => void |
() => { } |
Function executed after an unsuccessful query. If onUnauthorized is not defined, it also handles 401 status code |
| clientOptions | object | {} |
Extra Axios options, ex. {timeout: 1000}
|
| Parameter | Type | Description |
|---|---|---|
| isLoading | boolean |
true while the query is being executed, false otherwise, even if it has not yet started |
| isError | boolean |
true while the query finished unsuccessfully, false otherwise |
| isSuccess | boolean |
true while the query finished successfully, false otherwise |
| response | any | The query response if it finished successfully, undefined otherwise |
| error | any | The generated error if the query finished unsuccessfully, undefined otherwise. If it got a response, it can be accessed via error.response
|
| executeQuery | (data?: {}) => void |
Trigger the query with optional body as parameter |
This hooks allows to perform multiple queries in parallel with a syntax similar to that of useQuery.
| Parameter | Type | Default | Description |
|---|---|---|---|
| queries | object | Object where the key is the name of the query. The content variables are described below. | |
| -- url | string | Endpoint url | |
| -- method | string | 'GET' | Request method (GET, POST...) |
| -- data | object | { } | Request body |
| -- onSuccess | (response) => void |
Function executed after a successful query | |
| -- onUnauthorized | (error) => void |
Function executed after an unsuccessful query if the response code is 401 (optional, see onError). The default function is the one defined in the ApiProvider if it is not specified in useMultipleQueries. To disable the default one and not use an onUnauthorized set onUnauthorized=null
|
|
| -- onError | (error) => void |
Function executed after an unsuccessful query. If onUnauthorized is not defined, it also handles 401 status code |
|
| executeImmediately | boolean | false | Sets whether the call should be executed when the component is created or wait for the call to executeQueries()
|
| onEnd | (response) => void |
() => { } |
Function executed after after all the queries finished |
| clientOptions | object | {} |
Extra Axios options, ex. {timeout: 1000}
|
| Parameter | Type | Description |
|---|---|---|
| executeQueries | (data?: {}) => void |
Start the queries with optional body as parameter. data should be an object where the key is the name of the query and the value is the actual query data |
| errors | object | Object containing all the received errors. The key is the name of the query, the value is the error |
| responses | object | Object containing all the received successful responses. The key is the name of the query, the value is the response |
| statuses | object | Object containing the status of each query. The key is the name of the query, the value is the status |
| isLoading | boolean |
true if any calls are in progress, false otherwise, even if it has not yet started |
| queries | object | Contains all the information of each query. The key is the name of the query, the value is an object with the following queries: status, error, response
