Scala3 Scale By The Bay workshop

Welcome!

We'll be coding a simple HTTP API using Scala 3. Your task is to follow along and ask questions :)

Here's what you'll need to do beforehand:

1. clone this repository: git clone https://github.com/softwaremill/scala3-rental-seed.git
2. install sbt
3. in the scala3-rental-seed directory, run the sbt console using sbt. This should bring up the prompt:

sbt:scala3-rental-seed>

4. type compile. This should download the necessary dependencies and compile the HelloWorld source code. You should see a green [success] message shortly.
5. type run. This will run the sole main method defined in src/scala/rental/HelloWorld.scala, and should output:

[info] running rental.helloWorld
Hello, world!
[success] Total time: 1 s, completed Oct 22, 2021, 12:16:56 PM

6. although you can edit the source code in any text editor, it's more convenient to use an IDE. You can use IntelliJ IDEA with the Scala plugin, which has decent support for Scala3, although there are some rough edges. Or, if you are a VS Code user, try Metals.
7. try importing the project and running our Hello, world! example from the IDE. Note to IntelliJ users: you'll most probably need to change the default way of importing, so that it is done through sbt. To configure, after opening the project, go to the sbt tab on the right, click on the wrench on the far right ("Build Tool Settings"), choose "sbt settings", and tick the two checkboxes next to "sbt shell - use for project reload" and "build". Finally, reload (again on the sbt tab) and you're good to go.
