Scala Days 2025 Workshop - Real World ZIO

This is the code that we wrote during the Scala Days 2025 workshop, Real World ZIO.

The workshop walks you through the experience of writing a full-stack web application with the ZIO stack: a review-board for companies, in the style of Glassdoor.

The application is built with

• ZIO for effects, tests, config, logging and others
• Tapir for HTTP definitions, with ZIO HTTP as the server
• Quill for data storage
• Stripe for checkout
• Laminar on the frontend, integrated with ZIO

How to run

• have a docker database ready - this means, for dev purposes, docker compose up in the root folder
• in another terminal sbt, then project server, then ~compile to compile the server incrementally as you develop
• in the same terminal runMain com.rockthejvm.reviewboard.Application to start the server
• in another terminal sbt, project app and ~fastOptJS to compile the frontend
• in another terminal (that's 4 in total), go to the app/ directory, run npm install
• still in terminal 4, run npm run start to start serving the page
• go to http://localhost:1234 to see the page
