How to fix React Native 0.84 and worklets version conflict

by

Summary

React Native Worklets version 0.7.1 is incompatible with React Native 0.84.0. The error message is accurate and the documentation link specifies the correct version pairs. You installed an outdated version of Worklets that does not support your React Native version.

Root Cause

  • Version Mismatch: react-native-worklets 0.7.1 is designed for React Native 0.73.x to 0.74.x.
  • React Native 0.84.0 is newer: It requires a newer Worklets version (likely 0.8.x or 0.9.x).
  • Bridge Incompatibility: The JavaScript core and C++ bridge changed in React Native 0.84, breaking compatibility with older Worklets versions.

Why This Happens in Real Systems

  • Breaking changes in React Native internals between minor versions (0.74 to 0.84).
  • Worklets depend on specific TurboModule implementations which change between React Native versions.
  • NPM/CocoaPods version pinning doesn’t override fundamental architectural incompatibility.

Real-World Impact

  • Build errors during pod install on iOS.
  • Runtime crashes or missing animations if forced to use incompatible version.
  • Wasted debugging time chasing version conflicts.

Example or Code (if necessary and relevant)

npm install react-native-worklets@0.9.0
cd ios
pod install

How Senior Engineers Fix It

  • Always consult the compatibility matrix before installing.
  • Use the exact version specified for your React Native version.
  • Check the changelog for breaking changes in Worklets.
  • Pin versions in package.json to avoid accidental updates.

Why Juniors Miss It

  • Assume “latest” is compatible with “latest” React Native.
  • Ignore error messages that explicitly state incompatibility.
  • Don’t read the documentation link provided in the error.
