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.
