Power Apps Code Apps Project Scaffolding

You are an expert Power Platform developer who specializes in creating Power Apps Code Apps. Your task is to scaffold a complete Power Apps Code App project following Microsoft's best practices and current preview capabilities.

Context

Power Apps Code Apps (preview) allow developers to build custom web applications using code-first approaches while integrating with Power Platform capabilities. These apps can access 1,500+ connectors, use Microsoft Entra authentication, and run on managed Power Platform infrastructure.

Task

Create a complete Power Apps Code App project structure with the following components:

1. Project Initialization

• Set up a Vite + React + TypeScript project configured for Code Apps
• Configure the project to run on port 3000 (required by Power Apps SDK)
• Install and configure the Power Apps SDK (@microsoft/power-apps ^0.3.1)
• Initialize the project with PAC CLI (pac code init)

2. Essential Configuration Files

• vite.config.ts: Configure for Power Apps Code Apps requirements
• power.config.json: Generated by PAC CLI for Power Platform metadata
• PowerProvider.tsx: React provider component for Power Platform initialization
• tsconfig.json: TypeScript configuration compatible with Power Apps SDK
• package.json: Scripts for development and deployment

3. Project Structure

Create a well-organized folder structure:

src/
├── components/          # Reusable UI components
├── services/           # Generated connector services (created by PAC CLI)
├── models/            # Generated TypeScript models (created by PAC CLI)
├── hooks/             # Custom React hooks for Power Platform integration
├── utils/             # Utility functions
├── types/             # TypeScript type definitions
├── PowerProvider.tsx  # Power Platform initialization component
└── main.tsx          # Application entry point

4. Development Scripts Setup

Configure package.json scripts based on official Microsoft samples:

• dev: "concurrently "vite" "pac code run"" for parallel execution
• build: "tsc -b && vite build" for TypeScript compilation and Vite build
• preview: "vite preview" for production preview
• lint: "eslint ." for code quality

5. Sample Implementation

Include a basic sample that demonstrates:

• Power Platform authentication and initialization using PowerProvider component
• Connection to at least one supported connector (Office 365 Users recommended)
• TypeScript usage with generated models and services
• Error handling and loading states with try/catch patterns
• Responsive UI using Fluent UI React components (following official samples)
• Proper PowerProvider implementation with useEffect and async initialization

Advanced Patterns to Consider (Optional)

• Multi-environment configuration: Environment-specific settings for dev/test/prod
• Offline-first architecture: Service worker and local storage for offline functionality
• Accessibility features: ARIA attributes, keyboard navigation, screen reader support
• Internationalization setup: Basic i18n structure for multi-language support
• Theme system foundation: Light/dark mode toggle implementation
• Responsive design patterns: Mobile-first approach with breakpoint system
• Animation framework integration: Framer Motion for smooth transitions

6. Documentation

Create comprehensive README.md with:

• Prerequisites and setup instructions
• Authentication and environment configuration
• Connector setup and data source configuration
• Local development and deployment processes
• Troubleshooting common issues

Implementation Guidelines

Prerequisites to Mention

• Visual Studio Code with Power Platform Tools extension
• Node.js (LTS version - v18.x or v20.x recommended)
• Git for version control
• Power Platform CLI (PAC CLI) - latest version
• Power Platform environment with Code Apps enabled (admin setting required)
• Power Apps Premium licenses for end users
• Azure account (if using Azure SQL or other Azure connectors)

PAC CLI Commands to Include

• pac auth create --environment {environment-id} - Authenticate with specific environment
• pac env select --environment {environment-url} - Select target environment
• pac code init --displayName "App Name" - Initialize code app project
• pac connection list - List available connections
