To start your Phoenix server (assumes you have a local PostgreSQL server):

• Install dependencies with mix deps.get
• Create and migrate your database with mix ecto.setup
• Start Phoenix endpoint with mix phx.server

This will start a dev configuration server by default.

To start using Docker:

• Run docker-compose up --build
• Get a CLI into the web image
• Run /app/bin/server remote to get a REPL
• Execute MessengerBot.Release.migrate in the REPL to run migrations

This will start a prod configuration server by default.

Now you can visit localhost:4000 from your browser. In this example, this will return an error page. The app only exposes the two webhook endpoints required (GET/POST http://localhost:4000/webhook).

If you have a local PostgreSQL server, you can simply run all the tests by running:

$ mix test

You can also run specific tests, like so:

# Runs all tests in review_test.exs
$ mix test test/messenger_bot/review_test.exs

# Runs a specific test in review_test.exs
$ mix test test/messenger_bot/review_test.exs:30

Couple of options that work out of the box:

• Deploying on Heroku
• Deploying on Gigalixir
• Deploying on Render (unofficial guide)
