React Native CLI vs Expo in 2026: The Final Verdict

The Evolution

Feature Showdown

The Game Changer: CNG

Continuous Native Generation (CNG) is the philosophy that you should never have to manually edit your `android` or `ios` folders. Instead, you generate them on demand.

# The old way (CLI)
# You maintain android/ and ios/ folders forever.
# Upgrades are manual hell.

# The new way (Expo CNG)
npx expo prebuild

# This command generates android/ and ios/ folders from scratch
# based on your app.json config. You can delete them anytime!

With Prebuild, Expo generates the native projects for you based on your `app.json` and config plugins. This means your project stays clean, JavaScript-focused, and upgradeable.

How to use Native Modules with CNG?

In the past, you needed to eject to link native libraries. Now, you use Config Plugins.

{
  "expo": {
    "name": "MyApp",
    "plugins": [
      [
        "expo-camera",
        {
          "cameraPermission": "Allow $(PRODUCT_NAME) to access your camera"
        }
      ],
      "expo-localization"
    ]
  }
}

EAS: Superpowers for React Native

Is React Native CLI Dead?

Not dead, but specialized. The "Bare Workflow" (CLI) is still the foundation of Expo, but you rarely need to interact with it directly.

When to consider CLI:

• Brownfield Apps:

  If you are integrating React Native into a massive existing native iOS/Android app, CLI integration might be more straightforward (though Expo works here too).

• Platform Development:

  If you are building a fork of React Native itself or working on the core architecture.
