Custom Fetcher

This plugins generates a basic fetcher for you, but this might not useful in the real world. You can provide your own fetcher function which handles your use-cases.

You can configure this using the customFetcher config. It should be a string pointing to the file with custom fetcher. The file must export a function named fetcher and an interface FetcherOptions with the following signature:

export interface FetcherOptions<TQueryParams = never, TBody = never>
  extends Omit<RequestInit, 'body'> {
  url: string;
  queryParams?: TQueryParams extends never ? undefined : TQueryParams;
  body?: TBody extends never ? undefined : TBody;
}

export function fetcher<TResponse = unknown, TQueryParams = never, TBody = never>(
  options: FetcherOptions<TQueryParams, TBody>,
): Promise<TResponse> {
  // your code here
}

You can add additional properties to FetcherOptions as per your requirements, as these additional properties will be passed through from the hook to the fetcher.
