export { wrapFetch } from 'https://deno.land/x/fetch_goody@v2.0.0/mod.ts';

// this simple
const wrappedfetch = wrapFetch();

// you can also pass your own wrapped fetch function, allowing for wrapping fetch multiple times
const wrappedfetch = wrapFetch({ fetchFn: yourFetch });

const resp1 = await wrappedfetch("url",{
  form: {
    'foo': 'bar'
  }
}); // sets method to POST by default and converts object to FormData.

// or 

const resp2 = await wrappedfetch("url",{
  body: {
    'foo': 'bar'
  }
}); // is sent as json and corresponding header is set
// also if method is not defined for this, it will be set as POST

// other features:

// adding query string

const resp3 = await wrappedfetch("url",{
  qs: {
    'foo': 'bar'
  }
}); // results to url being sent to be "url?foo=bar"

// adding a response validator where you can throw errors

  validator(response: Response, init: ExtendedRequestInit) {
    if (response.status > 200) {
      throw new Error('yada');
    }
  }
