# multiplatform

Hi
Would like to share with you an open source project we’ve been working on since last year involving kotlin Multiplatform

TL;DR
Would love to get a feedback and maybe help from community with this multiplatform-libraries structure, or even merge into something bigger


At AirAsia we have an 11 years old super app , we do bookings for flights, hotels, taxi, activities, entertaining, chat …etc and so many other features,
And we were desperate for a shared logic approach to cutdown on development time, also we wanted a native approach (we already integrated react native to some parts of the app) .

We could not start from scratch with KMM project and wanted to support web and involve our backend services as well (shared models),
So we looked into multiplatform-libraries , after breaking down our modules we figured we might reach up to 40 libraries,
So we needed a scalable structure that we can maintain, also we needed a project starter !

so we ended up building kmp.telereso.io

it provides the following

• Project starter
• Each project outputs 2 libs
◦ Models - data classes (pojos) that can be shared with backend
◦ Lib - business logic
• 6 platform support , Android , iOS , Browser , backed (JVM,NodeJS) and ReactNative support ! (Currently Working on flutter )
• Core lib that supports
◦ Task (Multithread) - handle some of limitations on some platforms
◦ CommonFlow - flow wrapper for android , iOS and JS
◦ Logging
• Annotations
◦ Json Converters
◦ Builder
◦ ListWrapper (solve nested generic type introp in iOS), also List support for JS (generate array equivalent )
◦ ReactNative - auto generate a react native module by bridging into the android and iOS libs ("ReactNative interpolator")
• Gradle Plugin
There are more features can check at kmp.telereso.io and docs
We've finished 6 sdks so far some of them rolled out to prod, we will continue building both core and kmp-annotations to smooth sdk building and speed up development time

The React Native codegen is interesting. I’ve been thinking about building something like that

I generally don’t recommend using React Native, but for better or worse, there’s a lot of RN projects out there. Integrating native code into React Native can be painful. This makes it a bit easier

Yes especially iOS, need to maintain 2 files and one of them is in objective-c
so was a good use case for ksp to solve 🙌

Super cool!

Any thoughts on adding a method like “@SerializeParameters” that serializes all method parameters and the return type?

We end up doing this in a few places for JS because JS callers often have objects like { foo: bar } instead of class instances

[Ahmed na]

@ankushg this is what @ReactNativeExport does , it serialize none primitive types at native side then deserlize them at JS side (for a manager class)

so i think the logic is there but the output is a react native bridge,
if you like describe your use case here (what was the manual logic needed and how it was used)
i'll see if we can provide a new annotation !

[ankushg]

Interesting, didn’t realize that!

I’ll write up our use case and submit it, but it does look like a lot of the existing RN work is similar to what I’d be looking for
