react-native-deployment
OTA updates with CodePush, EAS Build, and release configurations. Use when configuring OTA updates, EAS Build, or managing release configs for React Native.
What this skill does
# React Native Deployment ## **Priority: P2 (MAINTENANCE)** ## Workflow: Ship Production Release with EAS Build 1. Configure `eas.json` with development, preview, and production profiles 2. Set environment variables in `.env.production` 3. Run `eas build --platform all --profile production` 4. Verify build artifact on EAS dashboard 5. Submit to stores: `eas submit --platform ios` / `eas submit --platform android` 6. For JS-only hotfixes, publish OTA: `eas update --branch production` ## Over-the-Air (OTA) Updates ### CodePush (Microsoft) - **JS-Only Updates**: Update JS bundle without app store review. - **Staging/Production**: Use separate deployments. - **Install**: `npm install react-native-code-push` - **Limitations**: Cannot update native code (Obj-C, Java, Swift, Kotlin). ### Expo Updates - **Expo Projects**: Built-in OTA updates via channels (dev, staging, prod). - **Install**: `expo install expo-updates` ## Build Configurations ### Expo (EAS Build) See [deployment reference](references/codepush-setup.md) for EAS build profile configuration and CLI commands. ### React Native CLI - **Android**: Use `productFlavors` in `build.gradle` (dev, staging, prod). - **iOS**: Use Xcode schemes. - **Fastlane**: Automate builds and uploads (`fastlane ios release`). ## Environment Management - **react-native-config**: `.env` files for API URLs, keys. - **Separate Configs**: `.env.dev`, `.env.staging`, `.env.production`. ## Anti-Patterns - **No OTA for Native Changes**: Requires store release. - **No Secrets in Code**: Use `.env` & CI secrets. - **No Manual Builds**: Automate with CI/CD. ## References See [references/codepush-setup.md](references/codepush-setup.md) for CodePush config, EAS profiles, and Fastlane automation.

generating-lwc-components
IncludedLightning Web Components with PICKLES methodology and 165-point scoring. Use this skill when the user creates or edits LWC components, builds wire service patterns, or writes Jest tests for LWC. TRIGGER when: user creates/edits LWC components, touches lwc/**/*.js, .html, .css, .js-meta.xml files, or asks about wire service, SLDS, or Jest LWC tests. DO NOT TRIGGER when: Apex classes (use generating-apex), Aura components, or Visualforce.
tanstack-query
IncludedManage server state in React with TanStack Query v5. Set up queries with useQuery, mutations with useMutation, configure QueryClient caching strategies, implement optimistic updates, and handle infinite scroll with useInfiniteQuery. Use when: setting up data fetching in React projects, migrating from v4 to v5, or fixing object syntax required errors, query callbacks removed issues, cacheTime renamed to gcTime, isPending vs isLoading confusion, keepPreviousData removed problems.
document-processor-api
IncludedProcess documents with Nutrient DWS. Use when the user wants to generate PDFs from HTML or URLs, convert Office/images/PDFs, assemble or split packets, OCR scans, extract text/tables/key-value pairs, redact PII, watermark, sign, fill forms, optimize PDFs, or produce compliance outputs like PDF/A or PDF/UA. Triggers include convert to PDF, merge these PDFs, OCR this scan, extract tables, redact PII, sign this PDF, make this PDF/A, or linearize for web delivery.

tanstack-query
IncludedManage server state in React with TanStack Query v5. Covers useMutationState, simplified optimistic updates, throwOnError, network mode (offline/PWA), and infiniteQueryOptions. Use when setting up data fetching, fixing v4→v5 migration errors (object syntax, gcTime, isPending, keepPreviousData), or debugging SSR/hydration issues with streaming server components.
accelint-nextjs-best-practices
IncludedNext.js performance optimization and best practices. Use when writing Next.js code (App Router or Pages Router); implementing Server Components, Server Actions, or API routes; optimizing RSC serialization, data fetching, or server-side rendering; reviewing Next.js code for performance issues; fixing authentication in Server Actions; or implementing Suspense boundaries, parallel data fetching, or request deduplication.
