hi! can you clarify the question? what precisely are you trying to accomplish?

I want to introduce a Metro plugin that hooks into the bundle process and protects the output bundle.

oh i see. yeah you can configure it in the same way as you could with any react-native app, just add this to app.json to point to the config:

{
  “expo”: {
    “packagerOpts”: {
      “config”: “metro.config.js”
    }
  }
}

Thank you for your reply.
However, the following error occurred.

Bundle output path not found.

Metro Bundler process exited with code 4294967295

The contents of metro.config.js are here.

// metro.config.js
const pjsdMetroPlugin = require('@preemptive/pjsd-metro-plugin')(
    // --PJSD configuration
    {
      configurationFile: './pjsd.config.json', // Path to the configuration file if any or you could put your configuration directly here
      quietMode: false, // Display protection logs
      protectUserModulesOnly: false /* Other PJSD options e.g. booleanLiterals, stringLiterals etc. could also be provided here */, // If false the whole bundle will be protected, otherwise only the "first-party" application code
    }, // --Metro configuration
    {
      resolver: {
        /* resolver Metro options */
      },
      transformer: {
        getTransformOptions: async () => ({
          transform: {
            experimentalImportSupport: false,
            inlineRequires: false,
          },
        }),
      },
      serializer: {
        /* serializer Metro options */
      },
      server: {
        /* server Metro options */
      } /* general Metro options */,
    },
  );
  
  module.exports = pjsdMetroPlugin;
