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.

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.

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, ReactiveCocoa, RxSwift Common APIs
Environment
Mac OS 10.12.6, CPU: 2.9GHz, Core i5 Xcode 9, iOS11, iPhone 8 Plus simulator
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 | | ------------- | -------- | --------- | -------- | ---------- | --------- | --------- | -------- | --------- | | EZRNode | 4775053 | 57487844 | 13851412 | 11966681 | 18972713 | 134567221 | 36076535 | 18388601 | | ReactiveCocoa | 6273485 | 102644235 | 66771529 | 80881225 | 496207382 | 327464977 | 29010632 | 100022454 | | RAC:EZRNode | 131.38% | 178.55% | 482.06% | 675.89% | 2615.37% | 243.35% | 80.41% | 543.94% |
Summary
ReactiveCocoa's average time consuming is 618.87% times more than EasyReact.
EasyReact will compare benchmark with RxSwift when the Swift version open source recently.
