Coursemology

Coursemology is an open source gamified learning platform that enables educators to increase student engagement and make learning fun.

Setting up Coursemology

System Requirements

1. Ruby (= 3.3.5)
2. Ruby on Rails (= 7.2.3.1)
3. PostgreSQL (= 16) with PGVector extension
4. ImageMagick or GraphicsMagick (For MiniMagick - if PDF processing doesn't work for the import of scribing questions, download Ghostscript)
5. Node.js (v22 LTS)
6. Yarn
7. Docker (installed and running)
8. Redis

Getting Started

We use Git submodules. Run the following command to initialize them before proceeding:

$ git submodule update --init --recursive

Coursemology consists of three main components:

1. Keycloak authentication provider
2. Ruby on Rails application server
3. React frontend client

Set up and run each component sequentially by following the linked documentation pages. As you proceed, open a new terminal window for each component after the previous component has been fully set up and started running.

Once each component has been set up and is running on their own terminals, you can access the app by visiting http://localhost:8080, and log in using the default user email and password:

email: test@example.org password: Coursemology!

Running using HTTPS locally

These commands should be run from the repository root directory, unless otherwise noted.

lvh.me is a public domain that resolves to 127.0.0.1. It is used instead of localhost because browsers enforce stricter security policies on localhost that can break the OAuth redirect flow over HTTPS.

1. Generate a self-signed certificate and key for lvh.me:

   openssl req -x509 -newkey rsa:4096 -sha256 -days 365 -nodes \
     -keyout config/credentials/server.key \
     -out config/credentials/server.crt \
     -subj "/CN=lvh.me" \
     -addext "subjectAltName=DNS:lvh.me,DNS:*.lvh.me"

   Puma and the webpack dev server both use these files automatically on startup.

2. Update the Keycloak redirect URIs to use HTTPS:

   bundle exec rake "keycloak:push_redirect_uris[https://lvh.me:8080]"

3. Start the app server with the public hostname:

   RAILS_HOSTNAME=lvh.me:8080 RAILS_ENV=development bundle exec puma

4. Start the client in HTTPS mode (from the client/ directory):

   yarn build:development-https

Access the app at https://lvh.me:8080. Your browser will show a certificate warning for the self-signed cert — ignore it or add a security exception.

Reverting to HTTP

1. Remove the certificate files so Puma falls back to HTTP:

   rm config/credentials/server.crt config/credentials/server.key

2. Restore the Keycloak redirect URIs:

   bundle exec rake "keycloak:push_redirect_uris"

3. Restart both the app server and client using the standard commands.
