Missing "babylon" and other dependencies? #24

slhck · 2020-01-27T10:49:14Z

I am using this in a RN 0.61.5 project, and I've installed the project with:

npm install react-native-obfuscating-transformer --save-dev

When running npx react-native start, I get this error:

Loading dependency graph...Failed to construct transformer:  Error: Cannot find module 'babylon'

After running npm i babylon --save-dev, I get:

My transformer.js is:

const obfuscatingTransformer = require("react-native-obfuscating-transformer");

module.exports = obfuscatingTransformer({
  /* options */
});

And my Metro Config:

module.exports = {
  transformer: {
    babelTransformerPath: require.resolve("./transformer"),
    getTransformOptions: async () => ({
      transform: {
        experimentalImportSupport: false,
        inlineRequires: false,
      },
    }),
  },
};

I see that Babylon is part of the dependencies: https://github.com/javascript-obfuscator/react-native-obfuscating-transformer/blob/master/package.json#L14 – but then again, there seem to be duplicates?

The text was updated successfully, but these errors were encountered:

Same issue here, same exact setup. Will continue digging and report back if I find anything.

EDIT: Try changing metro.config.js to the following:

module.exports = {
  transformer: {
    getTransformModulePath: () => {
      return require.resolve('./transformer');
    },
    getTransformOptions: async () => ({
      transform: {
        experimentalImportSupport: false,
        inlineRequires: false,
      },
    }),
  },
};

@slhck @Raymond-Cox any solution to this?

mrcarjul · 2020-02-08T00:12:35Z

add babylon and babel-traverse as dev dependencies.

razorabhu1995 · 2020-02-09T06:51:23Z

@mrcarjul After adding the dependencies, the above error is solved!!

But i get this:

Any solution to this?

Raymond-Cox · 2020-02-09T13:36:45Z

@slhck @Raymond-Cox any solution to this?

What happened when you changed metro.config.js file to what I suggested?

mrcarjul · 2020-02-10T22:04:49Z

@razorabhu1995

module.exports = obfuscatingTransformer({
/* add this to your transformer.js file i think it will fix it */
upstreamTransformer: require('metro-react-native-babel-transformer'),

byteab · 2020-02-13T06:42:06Z

@Raymond-Cox with your solution error is gone but nothing happened to source code it's not encrypted.

byteab · 2020-02-13T06:55:29Z

I think the contributors of this library must have a re iterate over how metro bundler work in react native >= 0.60

+1

@razorabhu1995 Did you manage to resolve this issue? I too am getting the error Error: Cannot find module 'metro/src/reactNativeTransformer'

dooleyb1 · 2020-03-23T15:51:18Z

@razorabhu1995 so the fix for this has actually already been merged into master, however it has not been deployed to npm. I manually implemented the changes within node_modules - see #15.

yarn add babylon -dev
