Juno Onboarding Ticket

[UZ9]

This is a dummy ticket intended to help new developers of Juno get more accustomed to its codebase structure.

You will be creating a new counter module in the db-service, and in the process learning the docker setup, prisma migrations, protobuf integration, and our end-to-end testing.

Requirements & Criteria

• Follow the README instructions to set up the Juno repository and successfully run the api-gateway e2e tests
• Create a new prisma model Counter with a string identifier (id) and int value. For all of your methods implemented below, an ID parameter will be specified.
• Create a new counter.proto with the following calls available: incrementCounter, decrementCounter, resetCounter, getCounter. These should all have their respective requests (e.g. IncrementCounterRequest)
• Create a new "counter" module in db-service under the modules folder. For reference, take a look at the NestJS documentation on modules and how other existing modules are handled.
• Create the following methods within the module: incrementCounter, decrementCounter, resetCounter, getCounter. Each should perform their respective name on the single counter you defined in prisma, using your defined proto definitions.
• Create a new "counter" module in api-gateway to allow your counter to be accessible via the API gateway. The module is responsible for calling the respective methods on the db-service.

Testing

• Create a new counter.e2e-spec.ts within db-service with at least 1 test for each method. For reference, take a look at other e2e-spec files within the same folder.
• Create a new counter.e2e-spec.ts within api-gateway with at least 1 test for each method (api-gateway implementation, not db-service). For reference, take a look at other e2e-spec files within the same folder.
