Welcome to ZIO

ZIO is a zero-dependency Scala library for asynchronous and concurrent programming.

Powered by highly-scalable, non-blocking fibers that never waste or leak resources, ZIO lets you build scalable, resilient, and reactive applications that meet the needs of your business.

• High-performance. Build scalable applications with minimal runtime overhead.
• Type-safe. Use the full power of the Scala compiler to catch bugs at compile time.
• Concurrent. Easily build concurrent apps without deadlocks, race conditions, or complexity.
• Asynchronous. Write sequential code that looks the same whether it's asynchronous or synchronous.
• Resource-safe. Build apps that never leak resources (including threads!), even when they fail.
• Testable. Inject test services into your app for fast, deterministic, and type-safe testing.
• Resilient. Build apps that never lose errors, and which respond to failure locally and flexibly.
• Functional. Rapidly compose solutions to complex problems from simple building blocks.

zio-project-seed.g8's Issues

Package names are not being properly filled

I was updating zio-shield to be uniform with the remaining projects in zio ecosystem and I noticed that sbt-build-info requires a package path and not the project name so:

.settings(buildInfoSettings("zio.shield")) instead of .settings(buildInfoSettings("zio-shield"))

There is a rule to make this in a "package" format but when prompted for a name and we put zio-arrow or zio-shield this is not populated as we expect.

Perhaps change the template to already fill in zio and just expect project name like arrow ?

Examples where this is a problem:

Build.sbt: .settings(buildInfoSettings("$name;format="lower,package"$"))
HelloWorld.scala: package $name;format="lower,package"$

Add Dotty Support

It would be great if Dotty was included in supported versions for new projects out of the box.

Add multi-project support

Many projects in the ZIO community are multi-project and it is non-trivial for those who are unfamiliar with sbt to modify the project according to their multi-project needs. Let's help them out with a multi-project seed.

Upgrade to ZIO 2.0

ZIO 2.0 is at Milestone 4, with an RC expected in the next few weeks.
https://github.com/zio/zio/releases/tag/v2.0.0-M4

The API is nearly stable at this point, so any early migration work against this version should pay off towards the official 2.0 release.

The progress is being tracked here:
zio/zio#5470

The Stream Encoding work in progress is the only area where the API might still change before the RC.

We are actively working on a ScalaFix rule that will cover the bulk of the simple API changes:
https://github.com/zio/zio/blob/series/2.x/scalafix/rules/src/main/scala/fix/Zio2Upgrade.scala
We highly recommend starting with that, and then working through any remaining compilation errors :)

To assist with the rest of the migration, we have created this guide:
https://zio.dev/howto/migrate/zio-2.x-migration-guide/

If you would like assistance with the migration from myself or other ZIO contributors, please let us know!

Add Cross-Platform Support

Currently it looks like this template does not support ScalaJS. I think we want to provide cross-platform and cross-version support across ZIO projects wherever possible. Having this as part of the template would be one less thing contributors have to worry about and would minimize effort for adding it later and risks that it will not be done in the optimal way.

So I updated the silencer plugin version and:

Then I updated the kind-projector plugin:

And the semanticdb-scalac version seems to be derived from scalafix plugin, so I updated that as well:

sbt:root> +compile

But zio 1.0.7 isn't published against scala, 3.0.0 but against an older RC version, so I updated zio version as well:

sbt:root> ;reload;+compile
[info] welcome to sbt 1.5.5 (Ubuntu Java 11.0.11)
…
[success] Total time: 14 s, completed 19 Jul 2021, 13:37:52

[info] set current project to root (in build file:/home/hochgi/dev/zio-sandbox/)
sbt:root> 

and finally build is working properly.
Will open a PR with these changes.
