The Kisi Backend Code Challenge

This repository can be used as a starting point for the Kisi Backend Code Challenge. Feel free to replace this README.md with your own when you submit your solution.

This repository contains:

• A bare-bones Rails 6 API app with a Gemfile that contains the neccessary libraries for the project.
• A configured adapter (lib/active_job/queue_adapters/pubsub_adapter.rb) to enqueue jobs. Use as a starting point for your own code.
• A rake task (lib/tasks/worker.rake) to launch the worker process. Use as a starting point for your own code.
• A class (lib/pubsub.rb) that wraps the GCP Pub/Sub client. Use as as a starting point for your own code.
• A Dockerfile and a docker-compose.yml configured to spin up necessary services (web server, worker, pub/sub emulator).

The reason we provide a Docker-setup is so that you don't have to set up a real GCP project, and can instead use the emulator. If you prefer not to use Docker, you can ignore the following text.

To start all services, make sure you have Docker installed and run:

$ docker compose up

If you prefer to start each service individually, run:

$ docker compose up web
$ docker compose up worker
$ docker compose up pubsub

To rebuild an image, run:

$ docker compose build web

To restart the worker, i.e. after a code change:

$ docker compose restart worker

To start a console:

$ docker compose run --rm worker bin/rails console

If you want to debug using pry and breakpoints, you might want to start a service manually instead:

$ docker compose run --rm worker bash
# bin/rails worker:run

If you run docker with a VM (e.g. Docker Desktop for Mac) we recommend you allocate at least 2GB Memory
