Would you have a look into this and merge?

[robertpaul01]

require("metro/src/reactNativeTransformer") is needed.

Also, the documentation should be updated to

module.exports = ({
  transformer: {
    babelTransformerPath: require.resolve("./transformer")
  },
});

[jes-carr]

Yes babelTransformerPath: require.resolve("./transformer") is in line 48 https://github.com/javascript-obfuscator/react-native-obfuscating-transformer/pull/7/files#diff-f48aafff6e296a5dab713b5ffbce17f5R48

I just commited the updated documentation

[marsinearth]

transformer: {

missed a colon

[marsinearth]

I used this pull request with yarn add javascript-obfuscator/react-native-obfuscating-transformer#7/head but keep getting cannot find module 'react-native-obfuscating-transformer' when react-native run-ios

[xkrsz]

@marsinearth it doesn't work, because you have to compile typescript first. Checkout to this branch, run yarn, tsc, and you should be good to go.

[sytler]

@krszwsk so the upstream transformer is broken here?

[xkrsz]

@sytler No, you just have to compile TS first in order to use the package from the repository directly.

[sytler]

@krszwsk have you tried this transformer on 0.57.7+? (metro@0.48.5)

[xkrsz]

@sytler yup, I ran it on 0.57.8

[sytler]

@krszwsk which version of javascript-obfuscator are u using? try to run yarn why javascript-obfuscator

[sytler]

Im using this config and somehow it is not working (it works in older project, with RN 0.55.4 (metro 0.30.2))

rn-cli.config.js

const { getDefaultConfig } = require("metro-config");

module.exports = (async () => {
  const {
    resolver: { sourceExts }
  } = await getDefaultConfig();
  return {
    transformer: {
      babelTransformerPath: require.resolve('./transformer'),
    },
    resolver: {
      sourceExts: [...sourceExts]
    }
  };
})();

transformer.js

const obfuscatingTransformer = require('react-native-obfuscating-transformer');
const typescriptTransformer = require('react-native-typescript-transformer');

module.exports = obfuscatingTransformer({
  upstreamTransformer: typescriptTransformer,
  obfuscatorOptions: {
    compact: true,
    // controlFlowFlattening: true,
    // controlFlowFlatteningThreshold: 0.75,
    // deadCodeInjection: true,
    // deadCodeInjectionThreshold: 0.4,
    debugProtection: false,
    disableConsoleOutput: true,
    identifierNamesGenerator: "hexadecimal",
    log: true,
    reservedStrings: ['import', 'require', 'class declaration', 'export'],
    rotateStringArray: true,
    seed: 1,
    selfDefending: false,
    sourceMap: true,
    sourceMapMode: "separate",
    stringArray: true,
    stringArrayEncoding: 'base64',
    stringArrayThreshold: 0.8,
    transformObjectKeys: false,
    unicodeEscapeSequence: true,
  },
  trace: true,
  emitObfuscatedFiles: false,
  enableInDevelopment: true,
});
