Description
As a person using the @dwyl app to be more personally effective, I do not want to stumble at the first hurdle trying to authenticate. I don't expect to see unfriendly/unrecoverable error messages, rather I expect to be able to recover from errors without drama.
At present our get_token/1 function is only following the "happy path":
https://github.com/dwyl/elixir-auth-google/blob/687fba552db8b5de2d353d42f77e2f04d9d428f9/lib/elixir_auth_google.ex#L18-L29
The callback function is parse_body_response/1 which does not handle the {:error, err}
This is fine during MVP because as early "dogfooding" users we are tolerant of the failure/errors. But as soon as we ship and show the MVP to (friendly) alpha test users, we need to have this done.
Todo:
- Research and document the various failure conditions and HTTP status codes
- Add failure
casestatement to handle all the error conditions. - Update the
templateto ensure that error conditions are displayed in a friendly way. - Update instructions in
README.md> How? section to inform people about error scenarios. - Re-publish the hex.pm package with the error handling.
We do not need to handle the failures before we ship our MVP, let's come back to this when it's needed.
