I am working on expo SDK Version: 36, and on all platforms (ios/android/web)

When installing react-navigation for the first time as described in the documentation and running jest –watch while doing it, and the following warning appeared:

    console.warn node_modules/react-native/Libraries/YellowBox/YellowBox.js:71
      Animated: `useNativeDriver` is not supported because the native animated module is missing. Falling back to JS-based animation. To resolve this, add `RCTAnimation` module to this app, or remove `useNativeDriver`. More info: https://github.com/facebook/react-native/issues/11094#issuecomment-263240420

It also happen in the browser console:

bundle.js:18272 Animated: `useNativeDriver` is not supported because the native animated module is missing. Falling back to JS-based animation. To resolve this, add `RCTAnimation` module to this app, or remove `useNativeDriver`. More info: https://github.com/facebook/react-native/issues/11094#issuecomment-263240420

The last one offers a solution, but it says to open Xcode, while I am on Linux Debian 10. I do not have Xcode. I can use a Macbook and do the step but I am wondering:

  • Should I care when working on Linux?
  • Should I care when working on Macbook (if it happens)?
  • Should I care for the health of my app while testing? Under which circumstances?

  1. You can safely ignore this warning. useNativeDriver is only important when running the code on device.

  2. To disable this warning add either of the following to your test file.

    jest.mock('react-native/Libraries/Animated/NativeAnimatedHelper');
    

    or

    jest.mock('NativeAnimatedHelp');
    

    In your package.json file

    "jest": {
        "setupFiles": [
          "./mock.js"
        ],
    

    In mock.js

    jest.mock('react-native/Libraries/Animated/NativeAnimatedHelper');
    jest.mock('NativeAnimatedHelp');

  3. Nothing above wasn’t working for me, but eventually I’ve found solution here:

    1. create jest-setup.js file (in my case in src/tests directory):

    src/tests/jest-setup.js:

    import 'react-native-gesture-handler/jestSetup';
    
    jest.mock('react-native/Libraries/Animated/src/NativeAnimatedHelper');
    
    jest.mock('react-native-reanimated', () => {
      const Reanimated = require('react-native-reanimated/mock');
    
      // The mock for `call` immediately calls the callback which is incorrect
      // So we override it with a no-op
      Reanimated.default.call = () => {};
    
      return Reanimated;
    });
    
    
    1. Install necessary packages (in my case react-native-reanimated only, but maybe your code will ask you something else):
    npm install --save-dev react-native-reanimated
    
    1. Add one row to jest config in package.json:
      "jest": {
        "setupFiles": [
          "<rootDir>/src/tests/jest-setup.js"
        ]
      },
    

    If your jest-setup.js file located in other directory – change location accordingly.

    After these simple steps, the annoying warning has gone. Thanks Spencer Carli and his article by link above.
