A tiny (< 1 kb) abstraction over building complex wrappers over the fetch API.

Installation

npm i http-with-fetch

Usage

import { CredentialsManager, createApiClient } from "http-with-fetch";

class DefaultCredentialsManager implements CredentialsManager {
  async attach(init: RequestInit, url: string) {
    init.credentials = "include";
    return init;
  }
  async isValid(_: Request, res: Response) {
    if (res.status === 401) {
      return false;
    }
    return true;
  }
}

const visitor = {
  async ok(response: Response) {
    return response.json();
  },
  async fail(request: Request, response: Response) {
    let error = await response.json();
    if (process.env.NODE_ENV !== "production") {
      console.error("API Call Failed: ", error, request);
    }
    throw new Error(error);
  },
};

const credentials = new DefaultCredentialsManager();

const client = createApiClient({ credentials, visitor }, false);

const list = client.get("/resource", { limit: 10 });
