# Dynamic Skill

> Fullstack development with bkend.ai BaaS platform

## Overview

The Dynamic skill enables fullstack web application development using bkend.ai as the Backend-as-a-Service platform. No server management required.

## When to Use

- Web applications with user accounts
- SaaS products
- MVPs with backend requirements
- Apps needing authentication
- Data-driven applications

## bkend.ai Features

- **Authentication**: Email, OAuth (Google, GitHub), Magic Links
- **Database**: MongoDB Atlas (REST API)
- **Storage**: S3 Presigned URL file uploads
- **Real-time**: WebSocket subscriptions (planned)
- **API**: REST API (`https://api-client.bkend.ai`)
- **MCP**: 28 tools + 4 resources (`https://api.bkend.ai/mcp`)

## Key Phases (Dynamic Level)

| Phase | Required | Description |
|-------|----------|-------------|
| 1. Schema | ✅ | Define data models |
| 2. Convention | ✅ | Set coding rules |
| 3. Mockup | ✅ | Design UI/UX |
| 4. API | ✅ | Design API endpoints |
| 5. Design System | 🔶 Optional | Component library |
| 6. UI Integration | ✅ | Connect frontend to API |
| 7. SEO/Security | 🔶 Optional | Auth hardening |
| 8. Review | 🔶 Optional | Code review |
| 9. Deployment | ✅ | Deploy to production |

## Getting Started

```bash
# Initialize Dynamic project
/dynamic init

# Start the pipeline
/development-pipeline start
```

## Authentication Example

```typescript
// lib/bkend/client.ts - REST API Direct Call Pattern
const BKEND_API_URL = process.env.NEXT_PUBLIC_BKEND_API_URL || 'https://api-client.bkend.ai';

async function bkendFetch(path: string, options: RequestInit = {}) {
  const response = await fetch(`${BKEND_API_URL}${path}`, {
    ...options,
    headers: {
      'Content-Type': 'application/json',
      'X-Project-Id': process.env.NEXT_PUBLIC_BKEND_PROJECT_ID!,
      'X-Environment': process.env.NEXT_PUBLIC_BKEND_ENVIRONMENT || 'dev',
      ...options.headers,
    },
  });
  if (!response.ok) throw new Error(`bkend API error: ${response.status}`);
  return response.json();
}

// Login
const { accessToken, refreshToken, user } = await bkendFetch('/auth/email/signin', {
  method: 'POST',
  body: JSON.stringify({ email, password }),
});
```
