Very Simple Example using ZIO + Quill

ZIO-Quill Getting Started

This is a very simple starter codebase using ZIO-Quill with some helpful scripts to automatically setup a postgres database. For a slighly more complete example try: quill-examples-zymposium.

• The code in src/main/scala/example/simple shows a really simple of example of how to use the quill-jdbc-zio context.
• The code in src/main/scala/example/module shows how to use the quill-jdbc-zio context using a module 2.0 pattern.

Instructions

1. Download and install docker.
2. Clone this repo: git clone 'https://github.com/deusaquilus/zio-quill-gettingstarted.git'
3. Run the start script: ./start.sh to start the postgres docker image.
4. Compile and run the examples: sbt 'runMain example.simple.Main' (or sbt 'runMain example.module.Main')

   > sbt 'runMain example.simple.Main'
