@SimonLab thanks for merging the update PR #7 ✅
Annoyingly, the deploy doesn't work because the buildpack is incorrect (my fault):

-----> Checking Erlang and Elixir versions
       Will use the following versions:
       * Stack heroku-18
       * Erlang 24.0
       * Elixir v1.12.3 
       Sorry, Erlang '24.0' isn't supported yet or isn't formatted correctly. For a list of supported versions, please see https://github.com/HashNuke/heroku-buildpack-elixir#version-support
 !     Push rejected, failed to compile Elixir app.
 !     Push failed

Just checked https://github.com/HashNuke/heroku-buildpack-elixir-otp-builds/blob/master/otp-versions
and it appears the latest available version is 23.3.2:

There is a PR to add OTP 24: HashNuke/heroku-buildpack-elixir-otp-builds#166 but it's sitting waiting ... ⏳

I can take a look at this in the evening. Need to do some "work work" now. ⏳

Todo

• Downgrade OTP version to 23.3.2
• Create PR
• Confirm successful deployment to Heroku

This should only take 2 mins but the lowest label we have is T25m ... see: dwyl/labels#99

We are getting a build error because WebPack uses arrow functions:

We don't need webpack in this project so I'm removing it.

With the release of elixir_auth_github at 1.5.0 and Phoenix 1.6 we need to update this demo to confirm everything still works as expected.

Todo

• Update Elixir to 1.12.3
• Update to Phoenix 1.6
  • Deletes package.json and unnecessary node.js dependencies! 🎉
• Update underlying dependency elixir_auth_github to 1.5.0 📦

Here's one we made earlier: dwyl/elixir-auth-github-demo#18

The demo app is currently working on heroku using "old" version: https://elixir-auth-google-demo.herokuapp.com/

I added a new branch to the demo

Annoyingly, while I'm trying to to update the dependency on auth_plug in auth: dwyl/auth#83 (comment)
I'm seeing this error:

no match of right hand side value: {:error, %HTTPoison.Error{id: nil, reason: {:options, {:sslv3, {:versions, [:"tlsv1.2", :"tlsv1.1", :tlsv1, :sslv3]}}}}}

I just confirmed that it's also an issue in this project/repo (elixir-auth-google-demo),
so I'm fixing it here first as this is a much simpler demo app.

As noted in the auth issue, I think updating the version of plug_cowboy should do the trick:

Heroku has kindly deleted our old demo app - that was consuming 0.0001 hours per month and basically cost them nothing ...
https://elixir-auth-google-demo.herokuapp.com/

So ...

Todo

• Deploy this app to Fly.io

The reason I'm opening this now is to help debug: dwyl/elixir-auth-google#83 💭
Which in turn will help ensure that our auth is working correctly. 👌

Related to: dwyl/learn-heroku#52

At present this demo app uses:

Should we upgrade it to 1.7 RC2?

Instructions to update would be similar to: dwyl/phoenix-chat-example#149
.then we could also update the setup instructions as suggested by @ndrean in dwyl/elixir-auth-google#73 (comment) 💭
