Resolves #538.
Changeset is based on #521 (please review/merge #521 first).
Before this PR the app showed a generic error message when the backend was unreachable.
After this PR the app displays an error message with more informative reason, e.g. "No connection to backend: Gateway Timeout.".
At first I tried implementing this behaviour via the recommended
react-router-dom'serrorElementproperty (as described in the docs). However, this did not work for reasons not yet known. I will try it again with a future release, as this is a more appropriate error handling mechanism and also enables better separation of data and views, which would be nice to have.How to test
Checkout the
masterbranch and start the app (withnpm start) without starting the regtest environment - verify that you see a generic error message. Switch to this branch (git checkout error-page) and verify that you see a more informative message.📸 Before/After
