fix: use temporary node-fetch fork

[oliveriosousa]

• Change node-fetch dependency to the fork with fix´s

This change is needed to run the examples in the web sandboxes (like codesandbox and stackblitz) because ipfs depends on js-ipfs-utils and this one depends on node-fetch.

When testing the examples using the stackblitz it throws an error:

Unable to resolve package (node-fetch npm:@achingbrain/node-fetch@^2.6.4) Please try installing a different version or range.

This resolution is being address in the js-ipfs-utils (see: ipfs/js-ipfs-utils#136)

@achingbrain could you please have a look ?

I think this module should depend on node-fetch and not an unmaintained fork of that module.

Unable to resolve package (node-fetch npm:@achingbrain/node-fetch@^2.6.4) Please try installing a different version or range.

The latest version of the fork is 2.6.7 - have you tried using that?

Alternatively, it looks like the problem you are trying to solve is that stackblitz/codesandbox don't support the "npm:module@version" syntax for dependency versions, you could link to the tarball directly? E.g:

  "node-fetch": "https://registry.npmjs.org/@achingbrain/node-fetch/-/node-fetch-2.6.7.tgz"

TBH I don't know if stackblitz/codesandbox support that format either but this repo feels like the wrong place to fix this problem.

Longer term we'll probably swap out node-fetch for the undici fetch command as it seems a little more 'official' and presents the same API (e.g. WHATWG streams), assuming it doesn't have any other problems.

It requires node 16 though, so it'll have to wait until node 16 becomes LTS, which is six weeks or so away.

Hi @achingbrain @hugomrdias,

Thanks for the suggestion, I've already updated the package.json targeting the tgz as suggested.

I ran the commands:

• npm run prepare : no issues
• npm run test: all green 👍

This PR is optional, just adds types to the project.

This module now uses undici and not node-fetch as its fetch fallback as it supports WHATGW streams.
