Examples

Bundle with sourcemap

The sourcemapOutput option allows you to specify the path of the source map relative to app folder:

    "bundle-ios": {
      "executor": "@nx/react-native:bundle",
      "options": {
        "entryFile": "src/main.tsx",
        "platform": "ios",
        "bundleOutput": "dist/apps/mobile/ios/main.jsbundle",
        "sourcemapOutput": "../../dist/apps/mobile/ios/main.map",
      }
    },
    "bundle-android": {
      "executor": "@nx/react-native:bundle",
      "options": {
        "entryFile": "src/main.tsx",
        "platform": "android",
        "bundleOutput": "dist/apps/mobile/android/main.jsbundle",
        "sourcemapOutput": "../../dist/apps/mobile/android/main.map",
      }
    }

Create a dev/release bundle

The dev option determines whether to create a dev or release bundle. The default value is true, by setting it as false, warnings are disabled and the bundle is minified.

    "bundle-ios": {
      "executor": "@nx/react-native:bundle",
      "options": {
        "entryFile": "src/main.tsx",
        "platform": "ios",
        "bundleOutput": "dist/apps/mobile/ios/main.jsbundle",
        "dev": false
      }
    },
    "bundle-android": {
      "executor": "@nx/react-native:bundle",
      "options": {
        "entryFile": "src/main.tsx",
        "platform": "android",
        "bundleOutput": "dist/apps/mobile/android/main.jsbundle",
        "dev": false
      }
    }

Create a minified bundle

The minify option allows you to create a minified bundle:

    "bundle-ios": {
      "executor": "@nx/react-native:bundle",
      "options": {
        "entryFile": "src/main.tsx",
        "platform": "ios",
        "bundleOutput": "dist/apps/mobile/ios/main.jsbundle",
        "minify": true
      }
    },
    "bundle-android": {
      "executor": "@nx/react-native:bundle",
      "options": {
        "entryFile": "src/main.tsx",
        "platform": "android",
        "bundleOutput": "dist/apps/mobile/android/main.jsbundle",
        "minify": true
      }
    }
