Response.redirect is not a function

[stelescuraul]

I`d like to be able to test the redirect functionality locally (as dummy test at least), but the Response.redirect function is not defined.

Do you have any plans on supporting it ?

const handler = async function(request) {
  return Response.redirect('some_url', 200);
};

addEventListener('fetch', async function(event) {
  event.respondWith(handler(event.request));
});

Thanks for the bug report. Give me a day or two to think about this. Intuitively, this should be supported. However, I just expose Request / Response as it’s provided by node-fetch, who has explicitly mentioned that it isn’t supported. Would you mind opening the ticket in that repo / post back with why they aren’t supporting it? If for whatever reason, node-fetch won’t support it, then I’ll accept a pr for the same

node-fetch doesn't have it supported but isomorphic-fetch does.
I just copy pasted the shim from isomorphic-fetch into my project:

const redirectStatuses = [301, 302, 303, 307, 308];

if (!Response.redirect) {
  Response.redirect = function(url, status= 302) {
    if (redirectStatuses.indexOf(status) === -1) {
      throw new RangeError(`Invalid status code: ${status}`);
    }

    return new Response(null, { status: status, headers: { location: url } });
  }
}

I think an upstream PR would be more appropriate.
