Spectrum: Hyperion build failing

[mattgaunt]

I had the repository working nicely on my iMac 10~ days ago, it worked great and I had no issues, setup docs are 👌!

I've just cloned the latest version onto my laptop this morning and I've hit a few roadblocks. Building hyperion seems to be falling over, it's telling me I haven't ran yarn run dev:web before running yarn run dev:hyperion, it seems that static/js/bundle.js is not being created. If I switch it to production it matches with main.js fine and boots up.

Once I'm past that issue, it's falling over whilst rendering when I request a page.

Error: 
fetch is not found globally and no fetcher passed, to fix pass a fetch for
your environment like https://www.npmjs.com/package/unfetch.

For example:
import fetch from 'unfetch';
import { createHttpLink } from 'apollo-link-http';

const link = createHttpLink({ uri: '/graphql', fetch: fetch });

Any ideas?

Update
After digging around, it seems the latter issue is introduced via this PR #3009 that was merged a couple of days ago

From the isomorphic-fetch docs:

This adds fetch as a global so that its API is consistent between client and server.

So that error makes sense.

It’s not explicit in its purpose by just requiring it there. Adding it back should resolve, and a comment too :-)

I also reproduced, should we revert https://github.com/withspectrum/spectrum/pull/3009 and add explicit comment?
i'm so sorry:bow:

Yeah, that'd be great @ryota-murakami—and no worries, it's totally my bad for not adding said comment in the first place!

@mxstbr i created Revert PR. https://github.com/withspectrum/spectrum/pull/3033
it's ready for review.
if you have improvements in isomorphic-fetch's comment, could you edit it directly?
