Raspi-pool is a swimming pool manager service to control devices (lights, water & heating pump, ...). It's also using sensors to get some data (e.g. temperate of the water).

1. Clone and enter the repo.

   git clone [email protected]:rv2e/raspi-pool.git
   cd raspi-pool

2. Install dependencies.

   nvm use
   yarn install

3. Run the backend.

   1. Create You Env The backend needs some credentials to work. They are directly taken from the .env file that you have to create. Feel free to copy the .env-sample file which contains a basic setup.

   2. Create Postgres Database You can use the db:create command to directly create the database:

      yarn db:create

   3. Apply The Migrations Before starting the application, your database needs the latest migrations. You can run this command:

      yarn db:migration:run

   4. Start The App You can use the start command or the start:dev (with hot reload) to run the application:

      yarn start[:dev]

      Now the server should listen to the port 3000.

4. Load the Jest tests in watch mode.

   Use the test command to run the tests in watch mode.

   yarn test:watch

   Notes:

   • The tests use another dotenv configuration. You can take a look at this file .env.test. Make sure to also create a database for the e2e tests.

5. Other useful commands.

   • Run the linter: yarn lint
   • Build the app: yarn build
   • Generate migrations: yarn db:migration:generate -n <migration_name>
   • Seed the database: yarn db:seed

Once docker and postgres are installed correctly, the image can be built then ran:

  nohup docker build -t raspi-pool . &

  nohup docker run --rm --device /dev/mem --device /dev/gpiomem -p 3000:3000  --privileged -t raspi-pool &
