Crashes in Release mode on 0.56.0

[Amnesthesia]

I'm having some insanely strange bug, that I think is related to http://babeljs.io/docs/en/babel-plugin-transform-class-constructor-call being removed in @babel 7

I've spent all day trying to debug this, and it comes down to the icons. As soon as I remove all calls to <Icon ... />, the app works again.

This is with:
Xcode: 9.4
OS: MacOS High Sierra

This happens on Android too, so this is most likely a problem with transpiling one way or another.
Icons are linked properly, and debug mode works fine. This is with all babel dependencies forced to 7.0.beta47. It crashes with the following message:

2018-07-31 01:55:28.772888+0200 App[645:152282] { [TypeError: TypeError: TypeError: TypeError: undefined is not an object (evaluating '_getPrototypeOf2.default')

Same here, TypeError · TypeError: undefined is not an object (evaluating 'e.default') This error is located at: in r in Styled(r) in RCTView
My stacktrace pinpoints it at node_modules/react-native-vector-icons/lib/create-icon-set.js:21:70

[Amnesthesia]

@jrnk You've got a much more precise stack trace than I, have you found a workaround?

Wondering if it could be that https://github.com/oblador/react-native-vector-icons/blob/master/lib/create-icon-set.js#L40 this const is uppercase and babel (incorrectly) assumes this should be a class? I've had this problem with other non-class uppercase stuff since @babel 7, having to do stuff like:

import { Platform as platform } from "react-native";

This is preventing me from release at the moment :(

[jrnk]

@Amnesthesia not yet. Will post here if I do of course.
I'm also pretty confident it's a babel 7 transpiling issue; Not yet sure which one though :)

[Amnesthesia]

@jrnk I find it strange that this hasn't been caught (or reported) already, since 0.56 has been out for a month already What does your .babelrc look like?

[jrnk]

{
  "presets": ["react-native"],
  "plugins": [
    ["@babel/plugin-proposal-decorators", { "legacy": true }],
    [
      "@babel/plugin-transform-runtime",
      {
        "helpers": true,
        "polyfill": false,
        "regenerator": false
      }
    ]
  ]
}

[Amnesthesia]

Damn. Pretty much the same as mine, except I have flow as well.

[jrnk]

@Amnesthesia found the culprit.
See facebook/react-native#20150
Changing the app initialization to a require(workaround 2 in the OP) statement solved the release builds for now.

[Amnesthesia]

@jrnk I'm already doing that — so that must be something else :(

[jrnk]

@Amnesthesia mm :( did you also remove @babel/plugin-transform-runtime ?

[Amnesthesia]

@jrnk No! I didn't!! Oh my god please be that. I'm gonna give it a shot

[Amnesthesia]

Holy shit! It works! Thank you @jrnk!

If anybody else runs into this, this is what I've done:

1. Updated .babelrc to this:

{
  "env": {
    "development": {
      "presets": ["react-native", "@babel/preset-flow"],
      "plugins": [
        ["@babel/plugin-proposal-decorators", { "legacy": true }],
        "graphql-tag",
        "@babel/plugin-proposal-object-rest-spread",
        [
          "@babel/plugin-transform-runtime",
          {
            "helpers": true,
            "polyfill": false,
            "regenerator": false
          }
        ]
      ]
    },
    "production": {
      "presets": ["react-native", "@babel/preset-flow"],
      "plugins": [
        ["@babel/plugin-proposal-decorators", { "legacy": true }],
        "graphql-tag",
        "transform-remove-console"
      ]
    }
  }
}

2. package.json has this:

"resolutions": {
    "@babel/core": "7.0.0-beta.47",
    "@babel/runtime": "7.0.0-beta.47",
    "@babel/code-frame": "7.0.0-beta.47",
    "@babel/traverse": "7.0.0-beta.47",
    "@babel/types": "7.0.0-beta.47",
    "@babel/helper-module-imports": "7.0.0-beta.47",
    "@babel/register": "7.0.0-beta.47",
    "babel-core": "^7.0.0-bridge.0",
    "metro": "^0.38.2",
    "metro-babel-register": "^0.38.2",
    "metro-core": "^0.38.2",
    "metro-memory-fs": "^0.38.2",
    "babel-preset-react-native": "^5.0.2"
  },

3. index.js

import { AppRegistry } from 'react-native';
import applyDecoratedDescriptor from '@babel/runtime/helpers/es6/applyDecoratedDescriptor';
import initializerDefineProperty from '@babel/runtime/helpers/es6/initializerDefineProperty';
Object.assign(babelHelpers, {
  applyDecoratedDescriptor,
  initializerDefineProperty,
});

AppRegistry.registerComponent(
  'Coinalyze',
  () => require('./App/Containers/App').default,
);

OMG 🙀 @Amnesthesia @jrnk ❤️❤️❤️

I am trying to build for release for a RN 0.56 project with mobx decorators for two days now and your solution just worked!!!
Thanks a lot! 🤗

[fahidmohammad]

@rborn im trying to do the same since couple of days, and the release build is crashing.
This problem only occurs when using mobx-react.

I have also raised an issue in mobx-react repo.
Possible for you to share some info on the fix as im still getting below crash:

[tid:com.facebook.react.ExceptionsManagerQueue] Unhandled JS Exception: babelHelpers.applyDecoratedDescriptor is not a function.

[rborn]

@fahidmohammad you need to have .babelrc split in dev/production like here #801 (comment)

Alsop keep @babel/* vesions to 7.0.0-beta.47

[fahidmohammad]

@rborn After updating the @babel/* version to 7.0.0-beta.47 and the .babelrc file all working fine now.

thank you so much for the help.

[ungaro]

Hi @rborn, thanks, it works now, but i've another problem. How do i do this with Higher Order Components?

Here is my new code:

import './shim'
import './ReactotronConfig'
import { AppRegistry } from 'react-native';
import applyDecoratedDescriptor from '@babel/runtime/helpers/es6/applyDecoratedDescriptor';
import initializerDefineProperty from '@babel/runtime/helpers/es6/initializerDefineProperty';
Object.assign(babelHelpers, {
  applyDecoratedDescriptor,
  initializerDefineProperty,
});

// RN 0.56 Release version crashes
// Workaround: RN 0.56 Release version crashes
// Sources:
//      https://github.com/facebook/react-native/issues/19827
//      https://github.com/facebook/react-native/issues/20150
AppRegistry.registerComponent(
  'AppName',
  () => require('./index_app').default,
);

import './shim'

import React from 'react'
import { AppRegistry } from 'react-native';
import Provider from './src/mobx'
import Amplify, { Auth} from 'aws-amplify'
import config from './src/aws-exports'
import { ApolloProvider } from 'react-apollo'
import App from './App';

import ApolloClient from "apollo-boost";

const client = new ApolloClient({
  request: async operation => {
   operation.setContext({
     headers: {
       referrer: "https://abc.com"
     }
   });
 },
 uri: "https://xyz-east-2.amazonaws.com/dev/graphql/"
});

export default class AppHome extends React.Component {
  constructor(props) {
    super(props);
    Amplify.configure(config)
  }
render() {
  return (
  <Provider>
    <ApolloProvider client={client}>
      <App />
    </ApolloProvider>
  </Provider>
  )
}
}

With this setup, i'm unable to access mobx stores, is there a way to use this and still access mobx stores with Higher Order Components?

My previous index.js was like this and could access all the mobx stores set in './src/mobx'

import './shim'

import React from 'react'
import { AppRegistry } from 'react-native';
import App from './App';
import Provider from './src/mobx'
import Amplify, { Auth} from 'aws-amplify'
import config from './src/aws-exports'
import { ApolloProvider } from 'react-apollo'

import ApolloClient from "apollo-boost";

const client = new ApolloClient({
   request: async operation => {
    operation.setContext({
      headers: {
       referrer: "https://abc.com"
      }
    });
  },
 uri: "https://xyz-east-2.amazonaws.com/dev/graphql/"
});


Amplify.configure(config)

const AppWithData = () => (
  <Provider>
    <ApolloProvider client={client}>
      <App />
    </ApolloProvider>
  </Provider>
)

console.ignoredYellowBox = ['Warning', 'Remote']
AppRegistry.registerComponent('AppName', () => AppWithData);

@fahidmohammad where and how do you set your mobx stores?

Thanks,
Alp

[rborn]

@ungaro donno :(

[fahidmohammad]

@ungaro im using createStackNavigator below i have mentioned the implementation.

router.js

import { createStackNavigator } from 'react-navigation';

import ComponentA from './containers/ComponentA';
import ComponentB from './containers/ComponentB';

const stackNavigatorConfig = {
  initialRouteName: 'ComponentA',
  navigationOptions: {
    gesturesEnabled: false
  },
  // For disabling Animation
  transitionConfig: () => ({
    transitionSpec: {
      duration: 0,
      timing: Animated.timing,
      easing: Easing.step0
    }
  })
};

export default createStackNavigator({
  ComponentA: {
    screen: ComponentA,
  },
  ComponentB: {
    screen: ComponentB,
  }
}, stackNavigatorConfig);

/stores/index.js

import StoreItemA from './StoreItemA';

export default {
  StoreItemA: new StoreItemA()
};

/store/StoreItemA.js

import { observable } from 'mobx';

export default class StoreItemA {
  @observable query;
}

index.js

import React, { Component } from 'react';
import {
  AppRegistry,
} from 'react-native';
import { Provider } from 'mobx-react';
import {name as appName} from '../app.json';

import Stack from './router';

import stores from './stores';

export default class MobXApp extends Component {
  render() {
    return (
      <Provider {...stores}>
        <Stack />
      </Provider>
    );
  }
}

AppRegistry.registerComponent(appName, () => MobXApp);

But now i have another issue with MobX over React Navigation. The state management does not work properly with the above approach. Still digging a better approach.

If anyone can suggest a better implementation modal, will be highly appreciated.

@ungaro Can you show your .babelrc and package.json? The decision what was provided here #801 (comment) is not working for me - I'm using mobx too.
