CircleCI is a useful service for previewing document builds. However,
by default their artifact server behaves differently from a standard
static pages server, in that it does not render foo/bar from
foo/bar/index.html.
This CloudFlare Worker proxy fixes that, by fetching missing foo/bar
pages from foo/bar/index.html. It also tries foo/bar.html, just in
case (e.g., this is useful for static page builds in older versions of
the mystmd document engine, which did not yet provide index.html
pages).
Build artifacts are served at a URL of the form:
You can use the CircleCI Artifacts Redirector Action to automatically provide that link in the status of your GH preview build.
If you replace output.circle-artifacts.com with
circle.scientific-python.dev, the requests will go through this
proxy (see worker.js), and will render pages correctly, as described above.
TODO: Update circleci-artifact-redirector-action to accept a different base domain.
