Sending Http requests

Umi provides a simple HttpInterface that can be used to send HTTP requests. This allows any Umi plugin or third-party library to rely on whichever Http client the end-user chooses to use instead of ending up with multiple Http clients in the same project.

The HttpInterface only defines a single method send which accepts a generic HttpRequest<T> and returns a generic HttpResponse<U> such that T and U are the request and response body types respectively.

Umi defines various Http-related types such as HttpHeaders and HttpMethod that are used by the HttpRequest and HttpResponse types. In order to improve the developer experience around sending requests, Umi ships with a little request builder that can be used to create HttpRequest instances. You may want to check the API references of the HttpRequestBuilder type to learn more about it but here are some examples:

// GET JSON request.
await umi.http.send(request().get('https://example.com/users/1').asJson());

// POST Form request.
const data = { name: 'John Doe', email: 'john.doe@example.com' };
await umi.http.send(request().post('https://example.com/users').asForm().withData(data));

// PUT request with bearer token.
await umi.http.send(request().put('https://example.com/users/1').withToken('my-token'));

// GET request with abort signal
await umi.http.send(request().get('https://example.com/users').withAbortSignal(mySignal));
