在android的react-native release build中禁用minification和uglify

Question

I have properly working in development environment react-native application. I wanted to test it's performance and released a build, which crashes after the launch.

01-09 20:16:13.644 23215 23251 E ReactNativeJS: Object type 't' not found in schema.

01-09 20:16:13.648 23215 23251 E ReactNativeJS: Module AppRegistry is not a registered callable module (calling runApplication)

I couldn't determine the cause of crashing because of minification and uglify of the sources. Could you, please, help me with disabling it, because I already spent plenty of hours on it.

react-native version: 0.49.5

Answer 1

You can accomplish this with the use of the CLI tool, Haul

Haul bundle --minify false should do the trick, if not, Haul provides other commands as well.

Answer 2

putting --minify=false in extraPackagerArgs in android/app/build.gradle should do the job.

project.ext.react = [
    entryFile: "index.js",
    extraPackagerArgs: [ '--minify=false' ],
];

Answer 3

I think you should first test your app by unchecking dev mode on your in app developer menu.

i had the same problem and it took me some time to figure out.

i disabled the dev mode so it generates the JS bundle same like release bundle and i found the problem and fixed it.

If anyone got to here this might help:

node_modules/.bin/haul bundle --dev=false --config=node_modules/react-native-bundle-visualizer/src/webpack.haul.js

you can know more doing:
