What is EasyReact

EasyReact is an easy-to-use reactive programming framework.

Why use EasyReact

Are you confused by the functors, applicatives, and monads in RxSwift and ReactiveCocoa? It doesn’t matter, the concepts are so complicated that not many developers actually use them in normal projects. Is there an easy-to-use way to use reactive programming? EasyReact is born for this reason.

Features

Note: The “Node” listed below refer to EZRNode, a unified representation of various values (all object types) in EasyReact.

Xcode 8.0 +

How to run the example project

git clone this repo，excute pod install in Example/, then open EasyReact.xcworkspace.

Installation

CocoaPods

Add the following content in Podfile

pod 'EasyReact'

Then execute pod install

How to use (For a more detailed example, please see the test specs in the example project Tests/)

Unit Test

EasyReact contains a complete unit test with the relevant code in the Example/Tests folder. You can open the sample project and execute the Test command to run these unit tests.

Time-consuming Benchmarking with EasyReact and ReactiveCocoa Common APIs

Environment

Build Platform: macOS Mojave 10.14

IDE: Xcode 10.0(10A255)

Device: iPhone XS Max 256G iOS 12.0(16A366)

Cases

Single stage operations, such as listener, map, filter, flattenMap, etc.
Multicast operations, such as combine, zip, merge, etc.
syncWith operations

The scale of the test is based on 10 operating objects and 1000 triggers. For example, the listener method has 10 listeners and repeats the action of sending the value 1000 times. The unit of time is ns.

Result data

Repeat the above experiment 10 times to get the data as follows:

name	listener	map	filter	flattenMap	combine	zip	merge	syncWith
