Overview

Monix is a high-performance Scala / Scala.js library for composing asynchronous, event-based programs.

It started as a proper implementation of ReactiveX, with stronger functional programming influences and designed from the ground up for back-pressure and made to interact cleanly with Scala's standard library, compatible out-of-the-box with the Reactive Streams protocol. It then expanded to include abstractions for suspending side effects and for resource handling, and is one of the parents and implementors of Cats Effect.

A Typelevel project, Monix proudly exemplifies pure, typeful, functional programming in Scala, while being pragmatic, and making no compromise on performance.

Highlights:

  • exposes the kick-ass Observable, Iterant, Task, IO[E, A], and Coeval data types, along with all the support they need
  • modular, split into multiple sub-projects, only use what you need
  • designed for true asynchronicity, running on both the JVM and Scala.js
  • excellent test coverage, code quality, and API documentation as a primary project policy

Usage

Library dependency (sbt)

For the stable release (compatible with Cats, and Cats-Effect 2.x):

libraryDependencies += "io.monix" %% "monix" % "3.4.1"

Sub-projects

Monix 3.x is modular by design. See the sub-modules graph:

Sub-modules graph

You can pick and choose:

  • monix-execution exposes the low-level execution environment, or more precisely Scheduler, Cancelable, Atomic, Local, CancelableFuture and Future based abstractions from monix-catnap.
  • monix-catnap exposes pure abstractions built on top of the Cats-Effect type classes; depends on monix-execution, Cats 1.x and Cats-Effect
  • monix-eval exposes Task, Coeval; depends on monix-execution
  • monix-reactive exposes Observable for modeling reactive, push-based streams with back-pressure; depends on monix-eval
  • monix-tail exposes Iterant streams for purely functional pull based streaming; depends on monix-eval and makes heavy use of Cats-Effect
  • monix provides all of the above
