By ZIO News • Issue #27 • View online
It’s been a while, but we are back with the latest issue of the ZIO newsletter! 😎 🙌
This edition celebrates fantastic news about the release of Caliban 1.0. Big congratulations to Pierre Ricadat & contributors! 🥳
This issue is also full of Zymposium videos (a weekly meetup organized every Friday by Adam Fraser & Kit Langton), where you can learn from live coding featuring ZIO.👏
DevInsideYou has launched a new series on ZIO, which aims to show the development of a TODO application using ZIO. Meanwhile, James Ward and Bruce Eckel have teamed up to write a new book on ZIO, which promises to motivate as well as explain how to build modern applications with Scala 3 and ZIO.
Finally, Functional Scala 2021 is coming up in December, the first post-pandemic Scala event, hosted in the beautiful city of London, at the stunning Royal Geographical Society. In past editions of the conference, 50% of the talks were dedicated to ZIO. Grab your tickets with 15% off for the next 2 weeks only. 🙌

In addition to various other improvements, this release introduces smart assertions for ZIO Test. Smart assertions allow you to make assertions about expected behavior using ordinary Scala expressions that return Boolean values instead of specialized assertion operators.

Blog Articles
Several years ago, I was developing an application that dealt with money. It handled loans, deposits, monthly payments, and reports. Unlike other apps, where eventual consistency and stale data may not be an issue, here one slip could lead to financial ruin for the company.

In the previous article, we looked at the basics of ZIO. In this part we’re going to extend on that example and add the following: ZStream integration: we’re going to create our own stream that polls an external service, and we’re going to use the reactive-stream integration to query a Mongo database.

ZIO has a lot of rich mathematical structure, without you ever needing to know. But as a user of this open source library, this structure means you have a more predictable experience, with fewer edge cases.

I explain more about this on Reddit:

@kitlangton and @adamfraser have been doing an amazing job with Zymposiums. Yet again here we have another meetup, a little less formal but equally enriching.

This time showing how good architecture and best practices look like with ZIO.

Had a perfectly splendid chat this morning with @BruceEckel, @_JamesWard and Bill! 💕

You can take part in the splendidness yourself with this handy url.

Improved Caliban docs a little bit. I decided to emphasize on the great interoperability. Didn't realize there was that many!

HTTP server libs:
- Http4s
- Akka HTTP
- Play
- Finch
- ZIO HTTP

JSON libs:
- Circe
- Play JSON
- ZIO JSON

(it doesn't fit in a single tweet 😂)

I am starting this repo as a small contribution from my end to FP community so that everyone can learn.

Repo is for everyone who want to learn/interested in #ZIO, ZIO-Http, #AKKA Typed, #AKKAStreams & HTTP, Cats & Cats-Effects, and #Scala .

Prime number platform. A micro service platform implemented using @finagle for streaming between client/server and @grpcio for communication between services.
All platform implemented using pure functional @zioscala effect system.

ZIO-test aspects are awesome! 😍

Thanks to the efforts of @kitlangton and @adamfraser, ZIO Test now supports smart assertions.

A single `assertTrue` with ordinary Scala code (no matchers / assertions) gives you rich error messages! ♥️🙏 https://t.co/l4m95THzv5

Added these little badges to all ZIO repositories so people can easily see which projects are usable right away vs which ones are WIP. https://t.co/wrCHEYZmBA

Happy to announce the release of Caliban 1.0.0 🎉

After almost 2 years of developement and the help from 73 contributors, Caliban is mature enough to graduate from 0.x to 1.x.

Also in this release: laminar integration, schema stitching, etc.
