mat.chalmers.it

Your fast track to restaurants that are nearby from Chalmers Campus Johanneberg and Campus Lindholmen!

mat.chalmers.it gives IT students the ability to review restaurants and voice their opinion to let other people know about where you can get the best food.

Development

The easiest way to get started is via docker!

docker-compose up --build

docker-compose.yml sets up the following dependencies:

• Frontend and backend with hot reloading support.
• Postgres database for the backend.
• Redis instance for caching and saving of user sessions.
• The frontend, backend, a database, and a Redis instance for Gamma.

Adding or updating dependencies

Docker can be unforgiving when trying to update dependencies.

• Start with updating your dependencies in one of the package.json, either the one for the frontend or the one for the backend.
• Go into the frontend folder, and run yarn install, or go into backend and run npm install for the backend.
• Go back to the root folder, and run docker-compose rm. This will remove your volumes and any previously saved data.
• Run docker-compose build --force-rm --no-cache mat-frontend mat-backend.

After that, you can just run docker-compose up to get started again.

Form validation

If you have to change form validation, do not forget to update it both in the frontend and the backend. In the frontend it's in frontend/src/validation, and in the backend it's in backend/src/controllers/validation. Note that text and error messages are not necessary for the backend validation.

Deployment

What's needed to run mat in production is:

• Frontend
• Backend
• PostgreSQL database
• Redis
• Reverse proxy (to run the frontend and backend from the same port)

Database migration

Right now there's no migration script installed on mat.chalmers.it. You'll have to do it manually. Just don't forget to make a backup before starting. In the future, there should be SQL files for migration in /database/migration.

Environment variables

The frontend has as of right now the gamma URL hardcoded to https://gamma.chalmers.it.

Environment variables for the backend:

• DB_HOST, DB_PORT, DB_USER, DB_DATABASE, DB_PASSWORD: Connecting to a PostgreSQL database.
• REDIS_HOST, REDIS_PORT: Connecting to a Redis instance.
• MAT_COOKIE_NAME, MAT_COOKIE_SECRET, MAT_COOKIE_AGE, MAT_COOKIE_DOMAIN: Cookie settings. See session.js for default settings.
• MAT_PORT: Port that the backend will run on. Default is 8080.

Gamma properties

mat.chalmers.it is designed with usage with Gamma. Note that the defaults are matched with the values in docker-compose.yml for ease to start developing locally.

• GAMMA_AUTHORITY: The name of the gamma authority. Default is admin.
• GAMMA_API_KEY: API key from Gamma. Default is key.
• GAMMA_CLIENT_ID, GAMMA_CLIENT_SECRET: Id and secret of the client from Gamma. Default is id/secret.
• GAMMA_BASE_URL: URL to gamma. Should be https://gamma.chalmers.it is production, otherwise, the default is used which points to the docker image.
• GAMMA_ME_URI: Default /users/me.
• GAMMA_TOKEN_URI: Default /oauth/token.
• GAMMA_USERS_URI: Default: /users/minified/.
• GAMMA_AUTHORIZATION_URL: Should be the full URL, probably: https://mat.chalmers.it/api/oauth/authorize. Default: http://localhost:8081/api/oauth/authorize.
• GAMMA_REDIRECT_URL: Should as well be the full URL, probably: https://gamma.chalmers.it/api/auth/account/callback. Default http://localhost:3001/auth/account/callback.
