How to Test Effects in ZIO | An Introduction to ZIO Test

Reading Time: 4 minutes In this blog, we’ll understand how to test ZIO effects using the ZIO Test library. Also, we’ll learn about some of the common assertions and a nice feature of ZIO Test which is test aspects. What is ZIO Test? ZIO Test is a testing library that makes it easy to test effectual programs. It treats effects as first class values and leverages the full power Continue Reading

Exceptions and Futures in Zio

Reading Time: 3 minutes ZIO is an open-source library that delivers a better “Future” for asynchronous and concurrent programming in Scala. Similarly, we can’t retry a Future in the event of failure, like we can for ZIO, because a Future isn’t a blueprint for doing something—it’s an executing computation. So if a Future fails, there is nothing else to do. We can only retrieve the failure. The central “type Continue Reading

What are Zio Effect Constructors?

Reading Time: 3 minutes In this blog post, we will discuss about ZIO effect constructors and how we can use them. Then we’ll take a look at Effect constructors for pure computations and side-effecting computations. Zio Effect Constructors A functional effect is a template for a concurrent workflow. The template which is mostly descriptive in nature, used to test for any side effects. Such as database interaction, logging, data Continue Reading

Experimenting with recursion and ZIO

Reading Time: 4 minutes If you’re already comfortable with recursion, you can skip the first part introducing tail-recursion and go directly to the ZIO section. Introduction: recursion and functional programming Recursion is one of the main techniques used in functional programming to replace an iterative loop. One of the most common examples is the Fibonacci computation or factorial computation. For this experiment, we will focus on an even simpler Continue Reading

Want to learn about Standard ZIO Services?

Reading Time: 3 minutes In this blog, we’ll talk about Standard ZIO Services and why it’s useful for us as programmers and how we can use them.Services provide well-defined interfaces that can be implemented differently in testing environments and production environments. Build-in services When we use the services we don’t need to provide their corresponding environment explicitly. ZIO provides built-in live version of ZIO services to our effects, so Continue Reading

Sequential Composition in Scala Zio

Reading Time: 3 minutes Overview In this blog we will discuss how the concurrent workflows can be simplified and can be executed in a sequential manner using flatmap and other sequential composition.The flatmap method of ZIO effect represents sequential composition where output of first effect act as input for the second. Further in this blog we will discuss some more operators that can define further workflow. You need to Continue Reading

How to Compose Layers in Zio

Reading Time: 5 minutes Introduction According to ZIO documentation, we know ZIO is a library for asynchronous and concurrent programming that promotes pure functional programming. The core of the ZIO library provides a powerful effect type ZIO inspired by Haskell’s IO monad. The value of this type doesn’t do anything itself. It is just a description of something that should be done.ZIO runtime system is responsible for actually doing what is Continue Reading

Composing and Chaining Effects together in ZIO

Reading Time: 3 minutes Introduction to ZIO ZIO is a library for asynchronous and concurrent programming that is based on pure functional programming. It combined with Scala help us to develop applications that are purely functional, asynchronous, type-safe, resilient, and testable. At the core of ZIO is ZIO data type which is defined as: ZIO is lazy! The difference between ZIO and procedural programming is quite straightforward. In the Continue Reading

How to handle Exceptions in Zio | Practical Implementation

Reading Time: 3 minutes In the previous blog ZIO Effects: How to Handle Errors? we have learned about How ZIO provides various means to handle and respond to failures. In addition to this blog, we will see all the ways to handle the exceptions with its Implementation. Either If the effect fails, the result is in the form of Left If the effect succeeds, the result is in the form Continue Reading

ZIO: The Most Important Data Type Of ZIO Library

Reading Time: 3 minutes Overview In this blog, we’ll understand about the most important data type of ZIO library i.e. ZIO and the type aliases available for it which are very useful when it comes to representing some common use cases. What is ZIO library used for? ZIO is a zero dependency Scala library that provides many features for developing concurrent, parallel, asynchronous and resources safe applications in a Continue Reading
