Cadet is the web application powering Source Academy.

Developer Setup

System Requirements

  1. Elixir 1.8
  2. Erlang/OTP 21
  3. PostgreSQL (>= 9.6)

Setting Up Local Development Environment

  1. Setup the development secrets (replace the values appropriately)
$ cp config/secrets.exs.example config/secrets.exs
$ vim config/secrets.exs
  • A valid luminus_api_key, luminus_client_id, luminus_client_secret and luminus_redirect_url are required for the application to properly authenticate with LumiNUS.
  • A valid cs1101s_repository, cs1101s_rsa_key is required for the application to run with the --updater flag. Otherwise, the default values will suffice.
  • A valid instance_id, key_id and key_secret are required to use ChatKit's services. Otherwise, the placeholder values can be left as they are.
  1. Install Elixir dependencies
$ mix deps.get
  1. Initialise development database
$ mix ecto.setup
  1. Run the server in your local machine
$ mix phx.server
  1. You may now make API calls to the server locally via localhost:4000. The API documentation can also be accessed at http://localhost:4000/swagger.

Obtaining access_token in dev environment

You can obtain access_token JWT of a user with a given role by simply running:

$ mix cadet.token <role>

For more information, run

$ mix help cadet.token

Handling CORS Preflight Request

We recommend setting up nginx to handle preflight checks using the following config file.

If you do this, do remember to point cadet-frontend to port 4001 instead of 4000

Chatkit

The chat functionality replacing the previous comment field found in assignments is built on top of Chatkit. Its documentation can be found here.

If you are using Chatkit, obtain your instance ID, key ID and secret key from your account, and set them in. Instructions to that are found here.

Internet connection is required for usage.

Style Guide

We follow this style guide: https://github.com/lexmag/elixir-style-guide and https://github.com/christopheradams/elixir_style_guide

Where there is a conflict between the two, the first one (lexmag) shall be the one followed.
