Veza Frontend

React + TypeScript frontend application for the Veza audio collaboration platform.

Quick Start

Prerequisites

• Node.js 18+ and npm
• Backend API running (see veza-backend-api/README.md)

Installation

npm install

Development

npm run dev

The application will be available at http://localhost:5173.

Building

npm run build

Setup Steps

1. Environment Variables

Copy .env.example to .env and configure:

# API Configuration
VITE_API_URL=http://localhost:8080/api/v1
VITE_WS_URL=ws://localhost:8081
VITE_STREAM_URL=http://localhost:8082

# Optional: Enable MSW mocks for development
VITE_USE_MSW=0

See .env.example for all available environment variables.

2. Type Generation

TypeScript types are generated from the OpenAPI specification. To regenerate types:

npm run generate:types

This script:

• Reads veza-backend-api/openapi.yaml
• Generates TypeScript types to src/types/generated/
• Creates barrel exports for easy importing

Note: Types are automatically generated in CI/CD before type checking.

3. Validation

Validate types and schemas:

# Type checking
npm run validate:types

# Schema validation
npm run validate:schemas

# Both
npm run validate:all

Available Scripts

Development

• npm run dev - Start development server
• npm run dev:lab - Start with lab environment (real database)
• npm run dev:mocks - Start with MSW mocks enabled

Building

• npm run build - Build for production
• npm run preview - Preview production build

Testing

• npm test - Run unit tests (Vitest)
• npm run test:ui - Run tests with UI
• npm run test:e2e - Run E2E tests (Playwright)

Code Quality

• npm run lint - Run ESLint
• npm run lint:fix - Fix ESLint issues
• npm run typecheck - Type check without emitting files
• npm run fmt - Format code with Prettier

Type Generation & Validation

• npm run generate:types - Generate TypeScript types from OpenAPI spec
• npm run validate:schemas - Validate Zod schemas
• npm run validate:types - Type check
• npm run validate:all - Run all validations

Design System

The application uses the Kodo design system:

• Colors: Kodo color palette (see src/styles/COLOR_USAGE.md)
• Components: Design system components in src/components/ui/
• Typography: Type scale system (see src/styles/TYPOGRAPHY_GUIDE.md)
• Spacing: Spacing scale system (see src/styles/SPACING_GUIDE.md)

See src/components/COMPONENT_USAGE.md for component usage guidelines.

ESLint Rules

The project enforces:

• Typography: Use type scale classes (text-xs, text-sm, etc.) instead of arbitrary sizes
• Spacing: Use spacing scale (gap-0 through gap-24) instead of arbitrary values
• Colors: Use Kodo design system colors instead of Tailwind defaults
• Components: Use design system Button component instead of native <button>

See eslint.config.js for full rule configuration.

Contributing

1. Follow the existing code style
2. Run npm run validate:all before committing
3. Ensure all tests pass: npm test
4. Type generation runs automatically in CI/CD

Troubleshooting

Type Generation Fails

Ensure veza-backend-api/openapi.yaml exists and is valid:

cd ../../veza-backend-api
swag init  # Generate OpenAPI spec

Build Errors

1. Clear node_modules and reinstall:

   rm -rf node_modules package-lock.json
   npm install
   

2. Clear Vite cache:

   rm -rf node_modules/.vite
   

Type Errors

Run type generation and validation:

npm run generate:types
npm run validate:types
