Support serving from a subpath (ie /pagerbeauty)

[tomwilkie]

Is your feature request related to a problem? Please describe.

I'd like to run pagerbeauty and serve is form a subpath (ie /pagerbeauty). We have a single https endpoint for tools, with an nginx forwarding various subpaths to those. This allows us to do access control centrally.

Describe the solution you'd like

An env var PAGERBEAUTY_HTTP_PATH=/pagerbeauty

Describe alternatives you've considered

I've tried having the nginx do all the rewrites in front of pagerbeauty, and got quite far - the redirect, the embedded scripts and styles etc. But the AJAX fetch of schedules.json is too much for a nginx rewrite.

Hey @tomwilkie. Thank you for your feedback. I thought AJAX fetches would work with relative paths; at least that's how I intended it to work. Might be a bug. I'll follow up on this later.

Thanks @sergiitk! Looks like they're using absolute URLs:

pagerbeauty/src/assets/javascripts/ui-pagerbeauty.jsx

Line 32 in e217a79

endpoint: '/v1/schedules.json',
