Implementing Matter in new environments example

[Orzech99]

Overview

Hello! I am currently working on integrating the core Matter.js functionality into a React Native application. From my understanding, there are several platform-specific parts that need to be implemented on my own. These are:

• BigInt/UInt8Array
• Network
• Crypto
• Storage
• Time
• BLE
• Wi-Fi/Thread Commissioning

Questions

1. Is my understanding correct that I need to implement these functionalities to get Matter.js working in a React Native environment?
2. Could you provide guidance or examples on where and how to implement these interfaces?

Additional Context

I have successfully used matter-node.js in a Node.js environment and am now transitioning to React Native. Any advice or pointers to relevant documentation would be greatly appreciated.

Future Contribution

After managing to get this to work, I plan to share my solution with the community. My side goal is to make the Matter protocol and Matter.js more accessible to a wider range of developers, especially those working with React Native.

Thank you for your help!

@Orzech99 Did you saw https://github.com/project-chip/matter.js/tree/main/packages/matter.js-react-native ?! We currently already work on react native and should be near to done ... The PR #988 is the current next/last step for next testing round.

So if you are familiar with react native please have a look at the package and code (there also your questions should be answered) also on the PR and provide Feedback if you see anything strange or broken.

With this last PR we "should" be fine because anything should be integrated ... reality tests will then show where ewe really stand. If you like to join these experiments and support in finalization you're welcome :-)

I hope you did not do too much work already, but if then maybe a good idea to compare :-)

I did see that, I pulled the latest update and built it on my own, now using it as a file package dependency so in case something 'goes wrong' I can look at the build package and trace back without searching in node_modules.

In my package.json:

"matter.js-react-native": "file:./packages/matter.js-react-native",

Is there any update on this? @Orzech99 Did you figure this out?

@joey01245 so … not everything that needs to be implemented for matter.js-react-native is implemented yet, we (@Apollon77 and me) did a couple more steps forward to make matter.js work on RN and got further but I decided to learn swift and kotlin to make native apps because matter sdk exists for both and my project has a strict timeline. If you are down to push this forward join the matter.js discord and contact @Apollon77 maybe you could make the final changes and get it to work on RN. My time is limited but I’m always happy to help - if you get somewhere and need help message me on discord as well. Apollon77 can connect us through discord.

In fact I am no mobile developer, so i fact if someone shares logs and errors I can solve issues and kill road blocks, but I'm currently not able do this myself. So if someone wants to use the package we have and continue the testing I am happy to support.
