I haven't yet came across readily available resources for large-scale application architecture for Elixir apps. I found Programming Phoenix to be a good start for that though. And there's ~30 years of knowledge in the Erlang land :)

For web apps, I found the abstractions that Elixir/Phoenix provides to be really helpful. Indeed, the list below is somewhat ORM focused.

In the small, Ecto.Schema, Ecto.Query, Ecto.Changeset, and Phoenix.View allow me to build highly composable and side-effect free modules. I can have many schemas, changesets and queries all interacting with the same underlying DB table(s) if I want to. Most of the side-effects (through Ecto.Repo for DBs) are usually in the Phoenix.Controller (or other Plugs).

Installing a Gem on Heroku from a Private GitHub Repo

Sometimes you want to use a gem on Heroku that is in a private repository on GitHub.

Using git over http you can authenticate to GitHub using basic authentication. However, we don't want to embed usernames and passwords in Gemfiles. Instead, we can use authentication tokens.

This method does not add your OAuth token to Gemfile.lock. It uses bundle config to store your credentials, and allows you to configure Heroku to use environment variables when deploying.

  1. Generate an OAuth token from GitHub
