Does Re.Pack Work with Expo (expo-cli) and EAS Build?

[woals4815]

Hi team,

I’m currently evaluating Re.Pack as an alternative bundler for a React Native project and I’d like to clarify its compatibility with the Expo ecosystem.

Specifically, I’m trying to understand:

1. Can Re.Pack run inside an Expo (expo-cli) project?

Since Expo uses Metro by default, I’m wondering whether Re.Pack can be integrated at the project level without ejecting or modifying the native build pipeline.

If integration is not supported, I’d like to confirm if the main blockers are related to the managed workflow, Metro Dev Server assumptions, or Expo's custom build environment.

2. Is Re.Pack compatible with EAS Build?

If I build the app using EAS Build, is it technically possible to replace Metro with Re.Pack during the native build process?

Does EAS provide any hooks or configuration surfaces that allow overriding the bundler?

Are there known limitations or recommended workarounds?

Context

I’m considering Re.Pack mainly for:

Faster builds (Webpack/Rspack)

Improved code splitting capabilities

Better long-term flexibility for a large-scale application

Before investing more time, I’d appreciate guidance on whether Expo’s current toolchain supports (or plans to support) this level of bundler customization.

Thanks in advance for any clarification!
