Overview

This skill is an Expo Mobile Architect that helps teams build cross-platform React Native apps with Expo. It covers Expo Router, EAS Build/Submit, development builds, native module integration, and production deployment. The focus is on fast iteration with Expo Go and reliable production workflows using EAS.

How this skill works

The skill inspects project setup, routing configuration, EAS build profiles, and native integration points to recommend concrete actions. It analyzes configuration and common failure modes to produce step-by-step fixes, build recipes, and validation checks. It also recommends when to use managed vs. bare workflows and how to maintain native capability access while preserving developer velocity.

When to use it

Starting a new cross-platform React Native app and choosing Expo vs bare React Native
Configuring Expo Router or migrating existing navigation to Expo Router
Setting up EAS Build/EAS Submit for CI and app store deployment
Adding or debugging native modules and development builds
Optimizing builds and runtime performance for iOS and Android

Best practices

Use Expo Go for rapid iteration; switch to development builds when native APIs or custom modules are needed
Define clear EAS build profiles for development, staging, and production to ensure repeatable builds
Keep native dependencies minimal; prefer community-managed Expo modules when possible
Validate app configuration and entitlements before submitting to app stores to avoid rejections
Automate EAS Build and Submit in CI and store credentials management

Example use cases

Migrate a React Native app to Expo Router with file-based routing and deep link support
Create EAS build profiles to produce reproducible dev/staging/prod artifacts and integrate with CI
Integrate a native analytics SDK using development builds and EAS config plugins
Diagnose failed EAS builds by examining native config and recommending fixes to provisioning or module installation
Optimize app startup and bundle size by auditing assets and lazy-loading heavy modules

FAQ

Use Expo Go for pure JS iteration. Switch to development builds when you need custom native modules, custom native code, or to reproduce production native behavior locally.

Can I keep using Expo and still add native modules?

Yes. Use config plugins and development builds or opt into the bare workflow for full native control. Prefer config plugins to maintain managed workflow benefits.

How do I make EAS builds reproducible across environments?

Pin SDK and dependency versions, define explicit EAS build profiles, store credentials securely, and include eas.json in version control. Use CI to run builds with the same environment.

What commonly causes EAS build failures?

Misconfigured provisioning/profile, incompatible native dependencies, missing config plugins, and mismatched SDK/gradle/Pod versions. Validate configs and dependency compatibility before builds.
