Build Commands

# Development build (custom dev client)
bunx eas build --profile development --platform ios
bunx eas build --profile development --platform android

# Preview (internal distribution)
bunx eas build --profile preview --platform all

# Production
bunx eas build --profile production --platform all

# Local build (no EAS servers)
bunx eas build --profile development --platform ios --local

OTA Updates

# Publish update to a channel
bunx eas update --channel preview --message "Fix login crash"
bunx eas update --channel production --message "v1.2.3 release"

# Check update status
bunx eas update:list

app.json update config:

{
  "expo": {
    "updates": {
      "url": "https://u.expo.dev/YOUR-PROJECT-ID",
      "enabled": true,
      "fallbackToCacheTimeout": 0,
      "checkAutomatically": "ON_LOAD"
    },
    "runtimeVersion": { "policy": "appVersion" }
  }
}

Handle updates in root _layout.tsx:

import * as Updates from 'expo-updates'
import { useEffect } from 'react'

export default function RootLayout() {
  // OTA update check is an SDK imperative call, not server data fetching --
  // React Query doesn't apply here. This is the only acceptable useEffect+async pattern.
  useEffect(() => {
    async function checkUpdate() {
      if (__DEV__) return
      const update = await Updates.checkForUpdateAsync()
      if (update.isAvailable) {
        await Updates.fetchUpdateAsync()
        await Updates.reloadAsync()
      }
    }
    checkUpdate()
  }, [])
  // ...
}

Submit to Stores

# After a production build
bunx eas submit --platform ios --latest
bunx eas submit --platform android --latest

# Submit specific build
bunx eas submit --platform ios --id BUILD_ID

EAS Secrets

# Set secrets (never commit these)
bunx eas secret:create --scope project --name API_SECRET_KEY --value "..."
bunx eas secret:create --scope project --name SENTRY_DSN --value "..."

# List secrets
bunx eas secret:list

Access in build via eas.json env:

{ "build": { "production": { "env": { "SENTRY_DSN": "$SENTRY_DSN" } } } }

GitHub Actions CI

.github/workflows/eas-build.yml:

name: EAS Build
on:
  push:
    branches: [main]

jobs:
  build:
    runs-on: ubuntu-latest
    concurrency:
      group: ${{ github.workflow }}-${{ github.ref }}
      cancel-in-progress: false
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with: { node-version: 22 }
      - uses: oven-sh/setup-bun@v2
      - run: bun install --frozen-lockfile
      - uses: expo/expo-github-action@v8
        with:
          eas-version: latest
          token: ${{ secrets.EXPO_TOKEN }}
      - run: bunx eas build --profile production --platform all --non-interactive

.github/workflows/eas-update.yml:

name: EAS Update
on:
  push:
    branches: [main]

jobs:
  update:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: oven-sh/setup-bun@v2
      - run: bun install --frozen-lockfile
      - uses: expo/expo-github-action@v8
        with: { eas-version: latest, token: '${{ secrets.EXPO_TOKEN }}' }
      - run: bunx eas update --channel production --message "${{ github.event.head_commit.message }}" --non-interactive

Rules

eas.json must have development, preview, and production profiles
Never hardcode API URLs in eas.json -- use EAS secrets or env vars
Never commit service-account.json or Apple credentials -- use EAS secrets
concurrency.cancel-in-progress: false in CI -- never cancel in-flight builds
runtimeVersion policy must be consistent across OTA updates and builds
Always test OTA update compatibility before shipping to production
