What problem does it solve? Building full-stack applications with AWS Amplify Gen2 requires coordinating TypeScript backend definitions (auth, data, storage, functions) with framework-specific frontend integration across React, Next.js, Vue, Angular, React Native, Flutter, Swift, and Android. This Skill provides validated, version-specific patterns that prevent common mistakes like misconfigured entry points, circular dependencies, and silent auth failures. ## Core Features & Use Cases - Backend Resource Definition: Configure Cognito auth (MFA, social login, passwordless, SAML via CDK), AppSync/DynamoDB data models with authorization rules, S3 storage, Lambda functions, REST/HTTP APIs, and AI conversation/generation routes via Bedrock. - Cross-Platform Frontend Integration: Framework-specific setup for 8 platforms, including Next.js App Router client components, React Native import ordering, and native mobile Authenticator components. - Deployment Workflows: Sandbox environments, CI/CD pipeline setup with IAM roles, branch-based multi-environment deployments, secrets management, and custom domains. - Use Case: A developer asks to add Google social login with owner-based data authorization to a Next.js app. The Skill routes to auth-backend.md for the defineAuth configuration with secret() handling, then to auth-web.md for the Authenticator component and Next.js SSR setup. ## Quick Start Ask the assistant to scaffold a new Amplify Gen2 project with authentication and a data model for your chosen framework.
