RGH handles only one API Token

Currently if you use RGH on a different domain and GitHub, as soon as you provide a token, the other site no longer works (as expected).

features.js:79 RefinedGitHubAPIError: The token seems to be incorrect or expired. Update it in the options.
    at call (chrome-extension://mnoacfgkaplmhhcgdnekddifjfcllloj/content.js:2481:11)
    at <anonymous>

We need to add the option to specify what URL the token is for and only use it for that domain. This becomes more important if #1713 is merged.

An alternative solution would be to extend webext-options-sync to have per-domain storage and we’d have automatic per-domain tabs (created by Refined GitHub) in the options.

This is actually kind of possible since webext-options-sync lets you change the storage key (currently stored as options in chrome.storage.sync), we just need to ensure that:

• supported domains are automatically added to the options page
• the form updates correctly when the domain tab is changed (perhaps by cloning the form and replacing it)
• that migrations, defaults and any listeners work correctly and don’t just pile up when switching domain.

https://github.com/sindresorhus/refined-github/pull/2111 contains code useful to generate those tabs (i.e. “what additional domains do we have permission to?”)

The further we go, the more I think this extension needs to be installed once per domain:

1. works with any number of Enterprise installations
2. it can be updated when GHE updates, rather than trying to keep RGH working with all versions: https://github.com/sindresorhus/refined-github/issues?q=label%3Aenterprise+label%3Abug

Given that GHE gets features later than regular GitHub, I expect most new features to cause errors so it’s always best to wait.

Rather than adding a field, I’d rather see documentation explaining how to:

• clone and build the extension locally, on a 1 month delay (e.g. HEAD@{ISO date 1 month ago})
• change the URLs in manifest.json so it applies to your GHE URLs instead of github.com
• merge in new changes from origin when the user wants to

Even better would be a cli tool that does this automatically, for any extension, like:

npx web-ext-custom-domain sindresorhus/refined-github github.com:github.mycompany.com --delay 30d

# roughly equivalent to
git clone https://github.com/"$1".git .
git checkout HEAD@"$delay"
npm install
npm run build
sed s/"$from_domain"/"$to_domain" distribution/manifest.json
dot-json distribution/manifest.json name "$name ($to_domain)"
