Comprehensive Testing: Develop thorough tests and stories for all components and features.

Key Libraries and Tools

Blockchain Integration

Wagmi: React hooks and wallet integration for Ethereum.
Viem: TypeScript interface for Ethereum, preferred over Ethers.js.
HAQQ Network: Specific integrations for the HAQQ blockchain.
EVM Compatibility: Ensure compatibility with the Ethereum Virtual Machine.

Core Technologies

React: For building user interfaces.
TypeScript: For static typing and type safety.
Nx: For monorepo management and build orchestration.
TanStack Query: For efficient data fetching and state management.
Tailwind CSS: For utility-first styling.

Blockchain Development Standards

Transaction Handling: Implement proper transaction lifecycle management and confirmations.
Wallet Integration: Support multiple wallet providers and handle connection states.
Gas Management: Implement proper gas estimation and fee handling.
Network States: Handle network switching and connection states.
Smart Contract Interaction: Use typed contract interfaces and proper ABI handling.

Security Considerations

Input Validation: Validate all user inputs, especially for transaction amounts and addresses.

Coding Standards

TypeScript Strict Mode: Enable and enforce strict type checking.
Functional Programming: Emphasize functional programming paradigms; avoid class-based components.
Named Exports: Use named exports for all components.
Component Design: Keep components small, focused, and reusable.
Composition Over Inheritance: Favor composition patterns over inheritance.
Error Handling: Implement robust error handling mechanisms.
Descriptive Naming: Use clear and descriptive names for variables and functions.
Documentation: Write comments and documentation in English.

File Structure Conventions

Directory Naming: Use lowercase with dashes (e.g.,
```
components/auth-wizard
```
).
Test Placement: Place test files adjacent to their implementation files.
Story Placement: Keep Storybook stories alongside their respective components.
Nx Workspace Structure: Follow Nx's recommended workspace organization.

Component Guidelines

Function Declarations: Define components using function declarations.
Props Interfaces: Name props interfaces as
```
[ComponentName]Props
```
.
Static Content: Place static content at the end of files.
Separation of Concerns: Separate presentation logic from business logic.
Styling: Use Tailwind CSS for all styling needs.
Accessibility: Ensure components are accessible and adhere to WCAG guidelines.

Testing Conventions

Unit Tests: Write unit tests for all business logic.
Integration Tests: Develop integration tests for complex workflows.
E2E Tests: Include E2E tests for critical workflows (especially wallet and blockchain interactions).
Mocking: Apply appropriate mocking strategies where necessary.
AAA Pattern: Follow the Arrange-Act-Assert pattern in tests.

State Management

Local State: Use React hooks for managing local component state.
Error Boundaries: Implement error boundaries to catch and handle errors gracefully.
Loading States: Handle loading states appropriately to enhance user experience.
Data Fetching: Follow best practices for data fetching and caching.
Transaction State: Manage transaction lifecycle states effectively.
Blockchain State: Handle chain and network state changes.
Wallet State: Manage wallet connection and account states.
Cache Management: Implement proper caching for blockchain data.

Performance Considerations

Code Splitting: Implement code splitting to optimize load times.
Memoization: Use
```
React.memo()
```
and
```
useMemo()
```
to prevent unnecessary re-renders.
Bundle Optimization: Optimize bundle size to improve performance.
Lazy Loading: Apply lazy loading for non-critical components and assets.

Error Handling

Error Boundaries: Use error boundaries to catch UI errors.
Typed Errors: Implement typed error handling for better type safety.
User Feedback: Provide user-friendly error messages.
Logging: Log errors appropriately for monitoring and debugging.
Transaction Errors: Handle blockchain transaction failures gracefully.
Network Errors: Manage network connection and RPC errors.
Wallet Errors: Handle wallet connection and signing errors.
Contract Errors: Process smart contract interaction errors.

Accessibility

WCAG Compliance: Ensure all components meet WCAG accessibility standards.
ARIA Attributes: Implement proper ARIA attributes for assistive technologies.
Keyboard Navigation: Ensure full keyboard navigability.
Screen Reader Testing: Test components with screen readers to verify accessibility.

Prioritization in Code Generation

When generating code, prioritize the following aspects in order:

Type Safety
Readability
Maintainability
Performance
Security

Project Structure

Location: All files are located inside the
```
libs/
```
and
```
apps/
```
directories, following Nx conventions.

Development Environment

Network Configuration: Set up proper RPC endpoints and chain configurations.
Local Development: Configure local development environment with proper network settings.
Testing Environment: Set up proper test networks and mock providers.
CI/CD: Configure proper build and deployment pipelines for blockchain applications.

Documentation Requirements

Transaction Flows: Document complex transaction flows and state changes.
Contract Interactions: Document smart contract interaction patterns.
Error Codes: Maintain documentation for blockchain-specific error codes.
Network Specifics: Document network-specific features and requirements.
