Scorer

This is Scorer, it's an API that returns a list of up to 2 users with points lower than a randomly selected amount.

The points of the users are refreshed every minute and the timestamp received in the response is the timestamp of the last request to the API.

Requirements

To start your application you'll need to have:

• Elixir 1.5 or greater installed.
• Postgres instance with the listening port set to 5432.
• The user scorer_user with password UltraPass#23 and permission to create and manage database.
• You may also choose to swap out the database access credentials in '/config/dev.exs'.

Startup

To start the Phoenix API server:

• Install dependencies with mix deps.get
• Create and migrate your database with mix ecto.setup
• Ensure PORT 4000 is free on your machine or update the PORT number in '/config/dev.exs' to your prefered PORT.
• Start Phoenix endpoint with mix phx.server

Now you can visit localhost:4000 from your browser (change 4000 to the appropriate PORT if you updated your config file with a different port).

You can expect to receive a response as below in your first request after the server is started:

{
 "timestamp":null,
 "users": [
    {"id":78,"points":12}
 ]
}

You can expect to receive a response as below in following requests:

{
 "timestamp":"2020-11-25 04:54:37",
 "users": [
    {"id":78,"points":12},
    {"id":53,"points":97}
 ]
}

This application is not set up to run in production.
