Custom Client

You can create your own adapter based on your preferences or requirements. You can use the bindings to achieve it. They will let you to easily connect into the library logic flow, so this way you will make your custom adapter without handling the internals on the library. We propose to use the getAdapterBindings util so you skip the sensitive and highly advanced part of connecting into hyper fetch flow.

Example

const customHttpAdapter = async () => {
  const {
    fullUrl,
    method,
    headers,
    payload,
    config,
    getAbortController,
    getRequestStartTimestamp,
    getResponseStartTimestamp,
    createAbortListener,
    onBeforeRequest,
    onRequestStart,
    onRequestProgress,
    onRequestEnd,
    onResponseStart,
    onResponseProgress,
    onResponseEnd,
    onSuccess,
    onAbortError,
    onTimeoutError,
    onUnexpectedError,
    onError,
  } = await getAdapterBindings(request, requestId);

  // ... any custom adapter logic, you can see axios implementation bellow
  axios({
    method,
    url: fullUrl,
    data: payload,
    headers,
    timeout: config.timeout,
  });
};

Setup

Connect any adapter to communicate with the server and handle it as you want, the only thing that has to match is the interface of the output.

const customHttpAdapter: AdapterType = (request: RequestInstance) => Promise.resolve([null, null, 0]);

const client = new Client({ url }).setAdapter(customHttpAdapter);

Typescript

You can pass custom options to your adapter from global setup and while request initialization. To make sure we pass correct configuration through this places we can specify the type for them. It is passed to the client instance.

type MyCustomAdapterOptions = {
  timeout?: number;
};

const client = new Client<Error, MyCustomAdapterOptions>({ url }).setAdapter(customHttpAdapter);
