Any update?

[AdamGerthel]

I'm curious about this as well. Mixpanel and RN AppsFlyer are my current blockers for moving to the new arch.

Hey there! @zihejia 👋🏻
Would it be possible to get some update on that topic?

• Is it being worked on internally?
• Are you waiting for external contributors?

The new arch is here, and close to being enabled by default and if Mixpanel becomes a blocker to update it might push away users.

+1 on Mixpanel starting to be a major blocker for us, not allowing is to move to the new arch.

@zihejia @jaredmixpanel - hi there! I work on expo and closely with the react-native team at meta on assisting in the roll out of the new architecture for react-native. we're moving towards enabling the new architecture by default in react-native later this year, and so we're proactively reaching out for maintainers of popular libraries to get the ball rolling in some third party libraries (more info).

here's a guide with more info on how you can proceed: "Enable the New Architecture for Libraries"

if you need any assistance, let us know! just a heads up that i've heard that at least one customer is considering moving away from mixpanel due to this blocking their migration to the new architecture, so it may be worth addressing sooner than later.

open new architecture cannot open ， please update

For those having trouble with this, we found a workaround using JS-only mode:

Follow instructions for Expo/Web set up: https://docs.mixpanel.com/docs/tracking-methods/sdks/react-native#expo-and-web-support

Then disable auto-linking the dependency with the react-native.config.js file:

module.exports = {
  dependencies: {
    'mixpanel-react-native': {
      platforms: {
        android: null,
        ios: null,
      },
    },
  },
};

This appears to keep the library running only on the JS layer without the need for the native side that is causing the app to crash. So far, this has given us the functionality that we need, but YMMV.

Update here: The folks at Meta have just merged this React Native PR to add support for com.facebook.react.bridge.Dynamic to the New Architecture: facebook/react-native#45944

Once that is released this issue should be resolved.

[cortinico]

We're planning to ship this hotfix to 0.75.x and 0.74.x

You can follow the status of those 2 picks here:

• [0.75] Add support for handling com.facebook.react.bridge.Dynamic as parameter for TurboModules reactwg/react-native-releases#439
• [0.74] Add support for handling com.facebook.react.bridge.Dynamic as parameter for TurboModules reactwg/react-native-releases#440

[PierreCapo]

Hello @jaredmixpanel is the support of com.facebook.react.bridge.Dynamic starting from 0.75 is enough or are you waiting to also get it merged into 0.74?

[jaredmixpanel]

@PierreCapo No changes are required on the Mixpanel side, this library should work with 0.75 now. I'll just keep this issue open until the 0.74 support is merged.

[PierreCapo]

Oh awesome, thanks Jared 🔥

[jaredmixpanel]

Closing this issue as reactwg/react-native-releases#440 is now also closed/merged

[Serdnad]

reactnative.directory is still showing this library as not supporting the New Architecture, is that just incorrect?

If it is, might be worth getting corrected, given that directory is what the official expo-doctor uses to report library support.

[jaredmixpanel]

@Serdnad Thanks for the heads up, I've opened a PR here: react-native-community/directory#1336

[niteshbalusu11]

@jaredmixpanel I know this issue is closed. I am still seeing this error:

 "mixpanel-react-native": "3.0.8",
  "react-native": "0.74.5",
   "expo": "^51.0.39",

Update: updating to react-native 0.74.6 fixed the issue.
