Get response headers about wretch HOT 4 CLOSED

Hi and thanks for the awesome lib!

Hi @mvasin, thanks!

Is there a way to get response headers when using wretch? I wasn't able to find anything in the docs.

Yes, you can get the headers them by using .res() to retrieve the raw fetch response object.

// see it in action here: https://runkit.com/embed/ydiucqoe45xu

wretch('...').get().res(res => {
    // 'res' is the raw response (see https://developer.mozilla.org/en-US/docs/Web/API/Response)
    // 'res.headers' contains the Headers (https://developer.mozilla.org/en-US/docs/Web/API/Headers)
    console.log(Array.from(res.headers.entries()))
    return res.text()
}).then(console.log)

from wretch.

If you need both headers and the json data, here's how I did it:

.res(response => {
	// do something with response.headers
	return res.json(); // or res.text() if you need text
})
.then(json => {...})

from wretch.

I had the same question myself and just wanted to att that this works response.headers.get('location')

from wretch.

What is the best way to pass headers further alongside with json data to resolve in then block ?

const successHandler = response => {
    console.log({response})
    if (response.status === 201) {
      let authToken = response.data["auth-token"];
      let { client } = response.data;
      let sessionCookie = response.headers["set-cookie"][0];

      onSuccess(authToken, sessionCookie, client);
    } else {
      errorHandler();
    }
  };

from wretch.
