Obfuscate selected source files when building for React Native.

yarn add react-native-obfuscating-transformer --dev 

or

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

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

const obfuscatingTransformer = require("react-native-obfuscating-transformer") module.exports = obfuscatingTransformer({ /* options */ })

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

const obfuscatingTransformer = require("react-native-obfuscating-transformer") module.exports = obfuscatingTransformer({ /* options */ })

Options are:

Defines what the first pass of code transformation is. If you don't use a custom transformer already, you don't need to set this option.

TypeScript example:

 const obfuscatingTransformer = require('react-native-obfuscating-transformer') + const typescriptTransformer = require('react-native-typescript-transformer') module.exports = obfuscatingTransformer({ + upstreamTransformer: typescriptTransformer })

Returns true for any files that should be obfuscated and false for any files which should not be obfuscated.

By default, it obfuscates all files in src/**/*

Warning — Not all options are guaranteed to produce working code. In particular, stringArray definitely breaks builds.

See the javascript-obfuscator docs for more info about what each option does.

Iff true, prints a list of files being obfuscated

Iff true, emits the obfuscated versions of files alongside their originals, for comparison.

Iff true, enables obfuscation in development mode.
