+### 4. Padrões de Plugin Development
+
+#### Criando Plugin Customizado
+```typescript
+// app/server/plugins/analytics.plugin.ts
+import type { Plugin, PluginContext } from '@/core/types'
+
+interface AnalyticsConfig {
+ enabled: boolean
+ trackRequests: boolean
+ trackErrors: boolean
+ reportInterval: number
}
-.btn-sm {
- padding: 0.25rem 0.5rem;
- font-size: 0.875rem;
+interface RequestMetrics {
+ path: string
+ method: string
+ timestamp: Date
+ responseTime: number
+ statusCode: number
}
-```
-```
-## Padrões de Estrutura de Arquivos
-
-### Controllers
-- Um controller por entidade
-- Métodos estáticos
-- Responsabilidade única
-- Validação de dados
-- Tratamento de erros
-
-### Routes
-- Um arquivo de rotas por entidade
-- Usar prefixos para agrupamento
-- Validação com TypeBox
-- Error handling consistente
-- Documentação inline
-
-### Components
-- Componentes funcionais
-- Custom hooks para lógica
-- Props tipadas
-- Responsabilidade única
-- Composição sobre herança
-
-### Types
-- Tipos compartilhados em `shared/`
-- Interfaces claras e descritivas
-- Request/Response patterns
-- Evitar `any`
-
-## Path Aliases - Padrões de Uso

-bun run build:backend # Apenas backend (dist/index.js)
-
-# Produção
-bun run start # Servidor de produção unificado
-bun run start:frontend # Frontend estático apenas
-bun run start:backend # Backend standalone
+## Padrões Anti-Patterns (❌ NÃO FAZER)
+
+### 1. ❌ Editar Core Framework
+```typescript
+// ❌ NUNCA FAZER - Editar core/
+// core/server/framework.ts
+export class FluxStackFramework {
+ // NÃO editar este arquivo!
+}
```
-### 🧪 Testes (30 testes inclusos)
-```bash
-bun run test # Modo watch (desenvolvimento)
-bun run test:run # Executar uma vez (CI/CD)
-bun run test:ui # Interface visual do Vitest
-bun run test:coverage # Relatório de cobertura
+### 2. ❌ Criar package.json Separado
+```json
+// ❌ NUNCA FAZER - app/client/package.json
+{
+ "name": "frontend", // Este arquivo não deve existir!
+ "dependencies": {
+ "react": "^19.0.0"
+ }
+}
```
-### 🔍 Verificação (se configurado)
-```bash
-bun run lint # ESLint unificado
-bun run typecheck # TypeScript check
-bun run format # Prettier (se configurado)
+### 3. ❌ Ignorar Type Safety
+```typescript
+// ❌ EVITAR
+const data: any = await api.users.get() // Perde type safety
+
+// ✅ CORRETO
+const data = await apiCall(api.users.get()) // Mantém types
```
-### Testando APIs (quando disponível)
-```bash
-# Health check
-curl http://localhost:3000/api/health
-
-# Testar endpoints
-curl http://localhost:3000/api/users
-curl -X POST http://localhost:3000/api/users \
- -H "Content-Type: application/json" \
- -d '{"name": "João", "email": "joao@example.com"}'
+### 4. ❌ Hardcoded Configuration
+```typescript
+// ❌ EVITAR
+const app = new FluxStackFramework({
+ server: { port: 3000 } // Hardcoded
+})
+
+// ✅ CORRETO
+const app = new FluxStackFramework({
+ server: {
+ port: parseInt(process.env.PORT || '3000', 10) // Configurável
+ }

-## Debugging e Troubleshooting v1.4.0
+### 5. ❌ Pular Testes
+```typescript
+// ❌ EVITAR - Não implementar sem testes
+export function criticalFeature() {
+ // Código sem testes
+}
-### 🔍 Hot Reload Intelligence
-```bash
-# Logs esperados no desenvolvimento:
-⚡ FluxStack Full-Stack Development
-🚀 API ready at http://localhost:3000/api
-✅ Vite já está rodando na porta 5173
-🔄 Backend hot reload independente do frontend
+// ✅ CORRETO - Sempre com testes
+export function criticalFeature() {
+ // Código testado em tests/
+}
```
-**Como funciona:**
-1. **Backend change** → Bun reinicia (~500ms), Vite continua
-2. **Frontend change** → Vite HMR (~100ms), backend não afetado
-3. **Vite já rodando** → CLI detecta e não reinicia
+## Workflow Recomendado para IAs
-### 🌍 URLs de Desenvolvimento
-- **Frontend integrado**: `http://localhost:3000`
-- **Frontend Vite**: `http://localhost:5173`
-- **API**: `http://localhost:3000/api/*`
-- **Swagger UI**: `http://localhost:3000/swagger`
-- **Health Check**: `http://localhost:3000/api/health`
-- **Backend standalone**: `http://localhost:3001`
+### 📝 Checklist para Novas Features
-### 🚫 Common Issues v1.4.0
+#### Antes de Começar:
+- [ ] ✅ **Verificar se lib existe**: `grep "" package.json`
+- [ ] 🔍 **Analisar arquitetura atual**: Entender como features similares foram implementadas
+- [ ] 📊 **Planejar testes**: Como a feature será testada?
-#### "Package.json not found in app/client"
-✅ **Solução**: Normal na v1.4.0! Não há mais package.json no client.
+#### Durante o Desenvolvimento:
+- [ ] 🎯 **Definir types em `app/shared/`**: Type-safety primeiro
+- [ ] 🏗️ **Criar controller testável**: Lógica de negócio isolada
+- [ ] 🛣️ **Implementar routes com Swagger**: Documentação completa
+- [ ] 🎨 **Integrar no frontend**: Eden Treaty para type-safety
+- [ ] 🧪 **Escrever testes abrangentes**: Unit + Integration tests
+- [ ] ⚙️ **Configurar adequadamente**: Usar sistema de config robusto
-#### "Library not found" no frontend
-✅ **Solução**: `bun add ` no root (instala para ambos)
+#### Depois de Implementar:
+- [ ] 🧪 **Rodar todos os testes**: `bun run test:run` (manter 100%)
+- [ ] 🔍 **Verificar TypeScript**: Zero erros obrigatório
+- [ ] 📚 **Testar Swagger docs**: Documentação funcionando?
+- [ ] 🔄 **Testar hot reload**: Both frontend e backend
+- [ ] 🏗️ **Build de produção**: `bun run build` funcionando?
-#### "Types not found" entre frontend/backend
-✅ **Solução**: Colocar tipos em `app/shared/types.ts`
+### 🚨 Comandos Essenciais para IAs
-#### "Vite not starting" ou "Port already in use"
-✅ **Solução**: CLI detecta automaticamente e não reinicia
+```bash
+# Verificar se lib já existe
+grep "" package.json
-#### "Eden Treaty types not working"
-✅ **Solução**: Verificar export `App` em `app/server/app.ts`
+# Instalar nova library (root do projeto)
+bun add
-#### "Hot reload not working"
-✅ **Solução**: Usar `bun run dev` (não `bun run legacy:dev`)
+# Desenvolvimento
+bun run dev # Full-stack
+bun run dev:backend # Backend apenas
+bun run dev:frontend # Frontend apenas
-### 🧠 Build Issues
-```bash
-# Limpar builds anteriores
-rm -rf dist/
-rm -rf node_modules/.vite/
+# Testes (manter 100% de sucesso)
+bun run test:run # Todos os testes
+bun run test:ui # Interface visual
-# Reinstalar dependências
-rm -rf node_modules/ bun.lockb
-bun install
+# Verificação de qualidade
+bun run build # Build production
+tsc --noEmit # Check TypeScript errors
-# Build limpo
-bun run build
+# Git workflow
+git add .
+git commit -m "feat: add new feature with tests"
```
-### 📊 Performance Monitoring
-```bash
-# Verificar performance da instalação
-time bun install # ~3-15s (vs ~30-60s dual package.json)
+### 🎯 Melhores Práticas Resumidas
-# Verificar hot reload
-# Backend: ~500ms reload
-# Frontend: ~100ms HMR
+1. **🔒 Type-Safety First**: Definir types antes de implementar
+2. **🧪 Test-Driven**: Escrever testes durante desenvolvimento
+3. **📚 Document Everything**: Swagger completo para todas as APIs
+4. **⚙️ Configure Properly**: Usar sistema de configuração robusto
+5. **🔄 Leverage Hot Reload**: Aproveitar recarregamento independente
+6. **📦 Monorepo Benefits**: Uma instalação, configuração unificada
+7. **🎨 Eden Treaty**: Type-safety automática client/server
+8. **🏗️ Plugin Architecture**: Extensibilidade via plugins
+9. **📊 Monitor Quality**: 312 testes, zero erros TS
+10. **🚀 Production Ready**: Build e deploy otimizados
-# Verificar build size
-ls -la dist/client/assets/ # Frontend bundles
-ls -la dist/index.js # Backend bundle

+
+## Plugin Types
+
+### 1. Basic Plugin Interface
+
+```typescript
+interface Plugin {
+ name: string
+ version?: string
+ description?: string
+ dependencies?: string[]
+ setup: (context: FluxStackContext, app: any) => void | PluginHandlers
+}
+
+interface FluxStackContext {
+ config: FluxStackConfig
+ isDevelopment: boolean
+ isProduction: boolean
+ logger: Logger
+ plugins: PluginManager
+}
+
+interface PluginHandlers {
+ onRequest?: (context: RequestContext) => void | Promise
+ onResponse?: (context: ResponseContext) => void | Promise
+ onError?: (context: ErrorContext) => void | Promise
+ onStart?: () => void | Promise
+ onStop?: () => void | Promise
+}
+```
+
+### 2. Advanced Plugin with Configuration
+
+```typescript
+interface ConfigurablePlugin extends Plugin {
+ defaultConfig?: T
+ validateConfig?: (config: T) => boolean | string[]
+ setup: (context: FluxStackContext & { pluginConfig: T }, app: any) => void | PluginHandlers
+}
+```
+
+## Creating Custom Plugins
+
+### Step 1: Basic Plugin Structure
+
+```typescript
+// plugins/my-custom-plugin/index.ts
+import type { Plugin, FluxStackContext } from '@/core/plugins/types'
+
+export const myCustomPlugin: Plugin = {
+ name: 'my-custom-plugin',
+ version: '1.0.0',
+ description: 'A custom plugin that does amazing things',
+
+ setup: (context: FluxStackContext, app: any) => {
+ // Plugin initialization code
+ context.logger.info(`Initializing ${myCustomPlugin.name}`)
+
+ // Add middleware or modify app
+ app.use(/* your middleware */)
+
+ // Return lifecycle handlers (optional)
+ return {
+ onRequest: async (requestContext) => {
+ // Handle incoming requests
+ },
+
+ onError: async (errorContext) => {
+ // Handle errors
+ }
+ }
+ }
+}
+```
+
+### Step 2: Plugin with Configuration
+
+```typescript
+// plugins/analytics/index.ts
+import type { ConfigurablePlugin, FluxStackContext } from '@/core/plugins/types'
+
+interface AnalyticsConfig {
+ endpoint: string
+ apiKey: string
+ trackRequests: boolean
+ trackErrors: boolean
+ batchSize: number
+}
+
+export const analyticsPlugin: ConfigurablePlugin = {
+ name: 'analytics',
+ version: '1.0.0',
+ description: 'Analytics and tracking plugin',
+
+ defaultConfig: {
+ endpoint: 'https://api.analytics.com/events',
+ apiKey: '',
+ trackRequests: true,
+ trackErrors: true,
+ batchSize: 100
+ },
+
+ validateConfig: (config: AnalyticsConfig) => {
+ const errors: string[] = []
+
+ if (!config.endpoint) {
+ errors.push('Analytics endpoint is required')
+ }
+
+ if (!config.apiKey) {
+ errors.push('Analytics API key is required')
+ }
+
+ if (config.batchSize < 1) {
+ errors.push('Batch size must be at least 1')
+ }
+
+ return errors.length === 0 ? true : errors
+ },
+
+ setup: (context: FluxStackContext & { pluginConfig: AnalyticsConfig }, app: any) => {
+ const { pluginConfig } = context
+ const eventQueue: any[] = []
+
+ const flushEvents = async () => {
+ if (eventQueue.length === 0) return
+
+ try {
+ await fetch(pluginConfig.endpoint, {
+ method: 'POST',
+ headers: {
+ 'Authorization': `Bearer ${pluginConfig.apiKey}`,
+ 'Content-Type': 'application/json'
+ },
+ body: JSON.stringify({ events: eventQueue.splice(0, pluginConfig.batchSize) })
+ })
+ } catch (error) {
+ context.logger.error('Failed to send analytics events:', error)
+ }
+ }
+
+ // Flush events every 30 seconds
+ const flushInterval = setInterval(flushEvents, 30000)
+
+ return {
+ onRequest: async (requestContext) => {
+ if (pluginConfig.trackRequests) {
+ eventQueue.push({
+ type: 'request',
+ method: requestContext.request.method,
+ url: requestContext.request.url,
+ timestamp: new Date().toISOString(),
+ userAgent: requestContext.request.headers.get('user-agent')
+ })
+ }
+ },
+
+ onError: async (errorContext) => {
+ if (pluginConfig.trackErrors) {
+ eventQueue.push({
+ type: 'error',
+ message: errorContext.error.message,
+ stack: errorContext.error.stack,
+ timestamp: new Date().toISOString(),
+ request: {
+ method: errorContext.request.method,
+ url: errorContext.request.url
+ }
+ })
+ }
+ },
+
+ onStop: async () => {
+ clearInterval(flushInterval)
+ await flushEvents() // Final flush
+ }
+ }
+ }
+}
+```
+
+### Step 3: Database Plugin Example
+
+```typescript
+// plugins/database/index.ts
+import type { ConfigurablePlugin, FluxStackContext } from '@/core/plugins/types'
+
+interface DatabaseConfig {
+ type: 'sqlite' | 'postgresql' | 'mysql'
+ url: string
+ pool?: {
+ min: number
+ max: number
+ }
+ migrations?: {
+ directory: string
+ auto: boolean
+ }
+}
+
+export const databasePlugin: ConfigurablePlugin = {
+ name: 'database',
+ version: '1.0.0',
+ description: 'Database connection and management plugin',
+ dependencies: ['logger'], // Requires logger plugin
+
+ defaultConfig: {
+ type: 'sqlite',
+ url: 'sqlite://./data/app.db',
+ pool: {
+ min: 2,
+ max: 10
+ },
+ migrations: {
+ directory: './migrations',
+ auto: false
+ }
+ },
+
+ setup: (context: FluxStackContext & { pluginConfig: DatabaseConfig }, app: any) => {
+ const { pluginConfig } = context
+ let connection: any = null
+
+ const initializeDatabase = async () => {
+ try {
+ // Initialize database connection based on type
+ switch (pluginConfig.type) {
+ case 'sqlite':
+ // connection = await initSQLite(pluginConfig.url)
+ break
+ case 'postgresql':
+ // connection = await initPostgreSQL(pluginConfig.url, pluginConfig.pool)
+ break
+ case 'mysql':
+ // connection = await initMySQL(pluginConfig.url, pluginConfig.pool)
+ break
+ }
+
+ context.logger.info(`Database connected: ${pluginConfig.type}`)
+
+ // Run migrations if auto is enabled
+ if (pluginConfig.migrations?.auto) {
+ await runMigrations(connection, pluginConfig.migrations.directory)
+ context.logger.info('Database migrations completed')
+ }
+
+ // Make connection available globally
+ app.decorate('db', connection)
+
+ } catch (error) {
+ context.logger.error('Failed to initialize database:', error)
+ throw error
+ }
+ }
+
+ return {
+ onStart: initializeDatabase,
+
+ onStop: async () => {
+ if (connection) {
+ await connection.close?.()
+ context.logger.info('Database connection closed')
+ }
+ },
+
+ onError: async (errorContext) => {
+ context.logger.error('Database error:', errorContext.error)
+ }
+ }
+ }
+}
+
+// Helper function example
+async function runMigrations(connection: any, directory: string) {
+ // Implementation for running database migrations
+ // This would read migration files from the directory
+ // and execute them in order
+}
+```
+
+## Plugin Registration
+
+### Method 1: Direct Registration
+
+```typescript
+// app/server/index.ts
+import { FluxStackFramework } from '@/core/server'
+import { myCustomPlugin } from './plugins/my-custom-plugin'
+import { analyticsPlugin } from './plugins/analytics'
+
+const app = new FluxStackFramework({
+ port: 3000
+})
+
+// Register plugins
+app.use(myCustomPlugin)
+
+app.use(analyticsPlugin, {
+ endpoint: 'https://my-analytics.com/events',
+ apiKey: process.env.ANALYTICS_API_KEY!,
+ trackRequests: true,
+ trackErrors: true,
+ batchSize: 50
+})
+
+app.listen()
+```
+
+### Method 2: Auto-Discovery
+
+```typescript
+// config/plugins.config.ts
+export const pluginConfig = {
+ discovery: {
+ enabled: true,
+ directories: [
+ './plugins',
+ './node_modules/@fluxstack-plugins'
+ ]
+ },
+ plugins: {
+ 'my-custom-plugin': {
+ enabled: true
+ },
+ 'analytics': {
+ enabled: true,
+ config: {
+ endpoint: process.env.ANALYTICS_ENDPOINT,
+ apiKey: process.env.ANALYTICS_API_KEY,
+ trackRequests: true,
+ trackErrors: true,
+ batchSize: 100
+ }
+ },
+ 'database': {
+ enabled: process.env.NODE_ENV === 'production',
+ config: {
+ type: 'postgresql',
+ url: process.env.DATABASE_URL,
+ pool: {
+ min: 5,
+ max: 20
+ }
+ }
+ }
+ }
+}
+```
+
+## Built-in Plugin Examples
+
+### Logger Plugin Structure
+
+```typescript
+// core/plugins/built-in/logger/index.ts
+export const loggerPlugin: Plugin = {
+ name: 'logger',
+ version: '1.0.0',
+ description: 'Request/response logging plugin',
+
+ setup: (context: FluxStackContext, app: any) => {
+ return {
+ onRequest: async (requestContext) => {
+ const start = Date.now()
+ requestContext.startTime = start
+
+ console.log(`→ ${requestContext.request.method} ${requestContext.request.url}`)
+ },
+
+ onResponse: async (responseContext) => {
+ const duration = Date.now() - (responseContext.startTime || 0)
+ const status = responseContext.response.status
+
+ console.log(`← ${status} ${duration}ms`)
+ },
+
+ onError: async (errorContext) => {
+ console.error(`✗ ${errorContext.error.message}`)
+ console.error(errorContext.error.stack)
+ }
+ }
+ }
+}
+```
+
+### Monitoring Plugin
+
+```typescript
+// core/plugins/built-in/monitoring/index.ts
+export const monitoringPlugin: ConfigurablePlugin = {
+ name: 'monitoring',
+ version: '1.0.0',
+ description: 'Performance monitoring and metrics collection',
+
+ setup: (context: FluxStackContext, app: any) => {
+ const metrics = {
+ requests: 0,
+ errors: 0,
+ avgResponseTime: 0,
+ responseTimes: [] as number[]
+ }
+
+ // Add metrics endpoint
+ app.get('/metrics', () => ({
+ ...metrics,
+ uptime: process.uptime(),
+ memory: process.memoryUsage(),
+ timestamp: new Date().toISOString()
+ }))
+
+ return {
+ onRequest: async (requestContext) => {
+ metrics.requests++
+ requestContext.startTime = Date.now()
+ },
+
+ onResponse: async (responseContext) => {
+ if (responseContext.startTime) {
+ const responseTime = Date.now() - responseContext.startTime
+ metrics.responseTimes.push(responseTime)
+
+ // Keep only last 100 response times for average calculation
+ if (metrics.responseTimes.length > 100) {
+ metrics.responseTimes.shift()
+ }
+
+ metrics.avgResponseTime =
+ metrics.responseTimes.reduce((a, b) => a + b, 0) / metrics.responseTimes.length
+ }
+ },
+
+ onError: async () => {
+ metrics.errors++
+ }
+ }
+ }
+}
+```
+
+## Plugin Testing
+
+### Unit Testing Plugins
+
+```typescript
+// plugins/analytics/__tests__/analytics.test.ts
+import { describe, it, expect, beforeEach, vi } from 'vitest'
+import { analyticsPlugin } from '../index'
+import type { FluxStackContext } from '@/core/plugins/types'
+
+describe('Analytics Plugin', () => {
+ const mockContext: FluxStackContext = {
+ config: {},
+ isDevelopment: true,
+ isProduction: false,
+ logger: {
+ info: vi.fn(),
+ error: vi.fn()
+ },
+ plugins: {} as any,
+ pluginConfig: {
+ endpoint: 'https://test.com/events',
+ apiKey: 'test-key',
+ trackRequests: true,
+ trackErrors: true,
+ batchSize: 10
+ }
+ }
+
+ const mockApp = {
+ use: vi.fn(),
+ get: vi.fn(),
+ post: vi.fn()
+ }
+
+ beforeEach(() => {
+ vi.clearAllMocks()
+ global.fetch = vi.fn()
+ })
+
+ it('should initialize with correct configuration', () => {
+ const handlers = analyticsPlugin.setup(mockContext, mockApp)
+
+ expect(handlers).toBeDefined()
+ expect(typeof handlers?.onRequest).toBe('function')
+ expect(typeof handlers?.onError).toBe('function')
+ })
+
+ it('should track requests when enabled', async () => {
+ const handlers = analyticsPlugin.setup(mockContext, mockApp)
+
+ const mockRequest = {
+ method: 'GET',
+ url: 'http://test.com/api/users',
+ headers: new Map([['user-agent', 'test-agent']])
+ }
+
+ await handlers?.onRequest?.({ request: mockRequest } as any)
+
+ // Verify request was tracked
+ // This would depend on your actual implementation
+ })
+
+ it('should validate configuration correctly', () => {
+ const validConfig = {
+ endpoint: 'https://api.test.com',
+ apiKey: 'valid-key',
+ trackRequests: true,
+ trackErrors: true,
+ batchSize: 50
+ }
+
+ const result = analyticsPlugin.validateConfig?.(validConfig)
+ expect(result).toBe(true)
+ })
+
+ it('should reject invalid configuration', () => {
+ const invalidConfig = {
+ endpoint: '',
+ apiKey: '',
+ trackRequests: true,
+ trackErrors: true,
+ batchSize: 0
+ }
+
+ const result = analyticsPlugin.validateConfig?.(invalidConfig)
+ expect(Array.isArray(result)).toBe(true)
+ expect((result as string[]).length).toBeGreaterThan(0)
+ })
+})
+```
+
+### Integration Testing
+
+```typescript
+// plugins/__tests__/integration.test.ts
+import { describe, it, expect, beforeEach } from 'vitest'
+import { FluxStackFramework } from '@/core/server'
+import { analyticsPlugin } from '../analytics'
+
+describe('Plugin Integration', () => {
+ let app: FluxStackFramework
+
+ beforeEach(() => {
+ app = new FluxStackFramework({ port: 3001 })
+ })
+
+ it('should register plugin successfully', () => {
+ expect(() => {
+ app.use(analyticsPlugin, {
+ endpoint: 'https://test.com/events',
+ apiKey: 'test-key',
+ trackRequests: true,

+ })
+ }).not.toThrow()
+ })
+
+ it('should handle requests with plugin enabled', async () => {
+ app.use(analyticsPlugin, {
+ endpoint: 'https://test.com/events',
+ apiKey: 'test-key',
+ trackRequests: true,

+ batchSize: 10
+ })
+
+ app.getApp().get('/test', () => ({ message: 'test' }))
+
+ const response = await app.getApp().handle(
+ new Request('http://localhost:3001/test')
+ )
+
+ expect(response.status).toBe(200)
+ })
+})
+```
+
+## Plugin Best Practices
+
+### 1. Error Handling
+
+```typescript
+export const robustPlugin: Plugin = {
+ name: 'robust-plugin',
+
+ setup: (context: FluxStackContext, app: any) => {
+ return {
+ onRequest: async (requestContext) => {
+ try {
+ // Plugin logic here
+ } catch (error) {
+ context.logger.error(`Plugin ${robustPlugin.name} error:`, error)
+ // Don't throw - let the request continue
+ }
+ }
+ }
+ }
+}
+```
+
+### 2. Configuration Validation
+
+```typescript
+validateConfig: (config: PluginConfig) => {
+ const errors: string[] = []
+
+ // Validate required fields
+ if (!config.requiredField) {
+ errors.push('requiredField is required')
+ }
+
+ // Validate types
+ if (typeof config.numericField !== 'number') {
+ errors.push('numericField must be a number')
+ }
+
+ // Validate ranges
+ if (config.port < 1 || config.port > 65535) {
+ errors.push('port must be between 1 and 65535')
+ }
+
+ return errors.length === 0 ? true : errors
+}
+```
+
+### 3. Resource Cleanup
+
+```typescript
+setup: (context: FluxStackContext, app: any) => {
+ const resources: any[] = []
+
+ return {
+ onStart: async () => {
+ const resource = await initializeResource()
+ resources.push(resource)
+ },
+
+ onStop: async () => {
+ // Clean up all resources
+ await Promise.all(
+ resources.map(resource => resource.close?.())
+ )
+ resources.length = 0
+ }
+ }
+}
+```
+
+### 4. Performance Considerations
+
+```typescript
+export const performantPlugin: Plugin = {
+ name: 'performant-plugin',
+
+ setup: (context: FluxStackContext, app: any) => {
+ // Use async operations sparingly
+ // Cache expensive computations
+ const cache = new Map()
+
+ return {
+ onRequest: async (requestContext) => {
+ // Avoid blocking operations
+ setImmediate(() => {
+ // Background processing
+ })
+
+ // Use caching
+ const cacheKey = requestContext.request.url
+ if (!cache.has(cacheKey)) {
+ cache.set(cacheKey, computeExpensiveValue())
+ }
+ }
+ }
+ }
+}
+```
+
+## Plugin Distribution
+
+### Publishing to npm
+
+```json
+{
+ "name": "@your-org/fluxstack-analytics-plugin",
+ "version": "1.0.0",
+ "description": "Analytics plugin for FluxStack",

-**🎯 Isso é tudo!** Não há mais:
-- ❌ `cd app/client && bun install` (postinstall hook removido)
-- ❌ Gerenciamento de dependências duplicadas
-- ❌ Sincronização de versões entre frontend/backend
-- ❌ Configurações separadas
+**🎯 URLs disponíveis imediatamente:**
+- 🌐 **App**: http://localhost:3000
+- 🔧 **API**: http://localhost:3000/api
+- 📚 **Docs**: http://localhost:3000/swagger
+- 🩺 **Health**: http://localhost:3000/api/health
+
+## Funcionalidades Principais
+
+### 1. Hot Reload Independente ⚡
+- **Backend**: Reinicia apenas quando arquivos `app/server/` mudam (~500ms)
+- **Frontend**: Vite HMR apenas quando arquivos `app/client/` mudam (~100ms)
+- **Inteligência**: Detecta se Vite já está rodando para evitar conflitos
+- **Coordenação**: Ambos os lados funcionam independentemente
+
+### 2. Type-Safety Automática 🔒
+```typescript
+// Backend define tipos automaticamente
+export const usersRoutes = new Elysia({ prefix: "/users" })
+ .get("/", () => UsersController.getUsers())
+ .post("/", ({ body }) => UsersController.createUser(body), {
+ body: t.Object({
+ name: t.String({ minLength: 2 }),
+ email: t.String({ format: "email" })
+ })
+ })
+
+// Frontend usa tipos automaticamente via Eden Treaty
+import { api, apiCall } from '@/lib/eden-api'
+const users = await apiCall(api.users.get()) // ✅ Fully typed
+const user = await apiCall(api.users.post({ // ✅ Autocomplete
+ name: "João", // ✅ Validation
+ email: "joao@example.com" // ✅ Type-safe
+}))
+```
+
+### 3. Sistema de Plugins Extensível 🔌
+**Plugins Built-in:**
+- **Logger**: Structured logging com diferentes níveis
+- **Swagger**: Documentação OpenAPI 3.0 automática
+- **Vite**: Integração inteligente com detecção de porta
+- **Static**: Servir arquivos estáticos em produção
+- **Monitoring**: Métricas de sistema e HTTP
+
+**Criar Plugin Customizado:**
+```typescript
+import type { Plugin } from "@/core/types"
+
+export const meuPlugin: Plugin = {
+ name: "analytics",
+ setup: (context: PluginContext) => {
+ context.app.onRequest(({ request }) => {
+ context.logger.info(`📊 ${request.method} ${request.url}`)
+ })
+
+ context.app.get("/analytics", () => ({
+ totalRequests: getRequestCount()
+ }))
+ }
+}
+```
+
+### 4. Sistema de Configuração Robusto ⚙️
+**Precedência Clara:**
+1. **Base Defaults** → Framework defaults
+2. **Environment Defaults** → Per-environment configs

-
-## 🔄 Hot Reload Inteligente e Independente
-
-### **Como Funciona (ÚNICO no mercado):**
-1. **Mudança no backend** → Apenas backend reinicia, Vite continua
-2. **Mudança no frontend** → Apenas Vite faz hot reload, backend não afetado
-3. **Vite já rodando** → FluxStack detecta e não reinicia processo
-
-### **Logs Esperados:**
-```bash
-⚡ FluxStack Full-Stack Development
-🚀 API ready at http://localhost:3000/api
-✅ Vite já está rodando na porta 5173
-🔄 Backend hot reload independente do frontend
-```
-
-### **Vantagem Competitiva:**
-- **Next.js**: Qualquer mudança → full reload
-- **Remix**: Dev server único → impacto em ambos
-- **FluxStack**: Reloads completamente independentes ✨

+# FluxStack v1.4.1 - Troubleshooting Guide
+
+## Common Issues and Solutions
+
+### Development Environment Issues
+
+#### Issue: `bun install` Fails or Slow
+```bash
+# Error: Installation taking too long or failing
+```
+
+**Solutions:**
+1. **Clear cache**: `bun pm cache rm`
+2. **Update Bun**: `bun upgrade`
+3. **Check permissions**: Ensure write access to project directory
+4. **Network issues**: Try `bun install --verbose` to see detailed logs
+
+#### Issue: Hot Reload Not Working
+```bash
+# Error: Changes not reflecting in browser/server
+```
+
+**Backend Hot Reload:**
+```bash
+# Check if using correct command
+bun run dev # ✅ Uses bun --watch
+bun run dev:backend # ✅ Standalone backend with hot reload
+
+# Avoid these
+bun app/server/index.ts # ❌ No hot reload
+```
+
+**Frontend Hot Reload:**
+```bash
+# Check Vite configuration
+bun run dev:frontend # Direct Vite development server
+# OR
+bun run dev # Integrated mode
+```
+
+**Troubleshooting Steps:**
+1. Check if files are being watched: Look for "watching for file changes" message
+2. Verify file extensions: Only `.ts`, `.tsx`, `.js`, `.jsx` files trigger reload
+3. Check path aliases: Ensure imports use correct paths
+4. Restart development server: `Ctrl+C` and run `bun run dev` again
+
+#### Issue: Port Already in Use
+```bash
+# Error: EADDRINUSE: address already in use :::3000
+```
+
+**Solutions:**
+```bash
+# Find process using the port
+netstat -ano | findstr :3000 # Windows
+lsof -i :3000 # macOS/Linux
+
+# Kill the process
+taskkill /PID /F # Windows
+kill -9 # macOS/Linux
+
+# Or use different ports
+FRONTEND_PORT=5174 BACKEND_PORT=3001 bun run dev
+```
+
+### Build and Production Issues
+
+#### Issue: Build Fails with TypeScript Errors
+```bash
+# Error: Type errors during build
+```
+
+**Solutions:**
+```bash
+# Check TypeScript configuration
+bun run type-check # Check types without building
+
+# Common fixes:
+1. Update shared types in app/shared/types.ts
+2. Check import paths use correct aliases (@/, @/shared/, etc.)
+3. Ensure all required types are exported
+4. Verify Eden Treaty types are properly generated
+```
+
+#### Issue: Production Build Missing Files
+```bash
+# Error: 404 errors for static assets in production
+```
+
+**Check Build Output:**
+```bash
+bun run build
+ls -la dist/ # Verify files are built
+
+# Expected structure:
+dist/
+├── client/ # Frontend build
+├── server/ # Backend build (optional)
+└── index.js # Main server entry
+```
+
+**Solutions:**
+1. Verify `vite.config.ts` output directory: `outDir: '../../dist/client'`
+2. Check static file configuration in production
+3. Ensure build script completes successfully
+
+#### Issue: Environment Variables Not Loading
+```bash
+# Error: process.env.VARIABLE_NAME is undefined
+```
+
+**Environment File Priority:**
+1. `.env.local` (highest priority)
+2. `.env.production` / `.env.development`
+3. `.env` (lowest priority)
+
+**Frontend Environment Variables:**
+```bash
+# Must be prefixed with VITE_
+VITE_API_URL=http://localhost:3000 # ✅ Available in frontend
+API_URL=http://localhost:3000 # ❌ Backend only
+```
+
+**Troubleshooting:**
+```bash
+# Check if environment file is loaded
+console.log('Environment:', {
+ NODE_ENV: process.env.NODE_ENV,
+ API_URL: process.env.API_URL,
+ VITE_API_URL: import.meta.env.VITE_API_URL # Frontend only
+})
+```
+
+### API and Backend Issues
+
+#### Issue: Eden Treaty Type Errors
+```bash
+# Error: Type 'unknown' is not assignable to type 'X'
+```
+
+**Common Causes:**
+1. Server types not properly exported
+2. Client importing wrong App type
+3. Route definitions not properly typed
+
+**Solutions:**
+```typescript
+// app/server/app.ts - Ensure proper export
+export type App = typeof app
+
+// app/client/src/lib/eden-api.ts - Correct import
+import type { App } from '../../../server/app' // ✅ Correct path
+import type { App } from '@/app/server/app' // ❌ May not resolve correctly
+```
+
+#### Issue: API Routes Not Found (404)
+```bash
+# Error: Cannot GET /api/users
+```
+
+**Troubleshooting Steps:**
+1. **Check route registration order:**
+```typescript
+// app/server/index.ts
+app.use(swaggerPlugin) // ✅ Swagger BEFORE routes
+app.routes(apiRoutes) // ✅ Routes registration
+```
+
+2. **Verify route prefixes:**
+```typescript
+// app/server/routes/index.ts
+export const apiRoutes = new Elysia({ prefix: "/api" }) // ✅ Correct prefix
+
+// app/server/routes/users.routes.ts
+export const usersRoutes = new Elysia({ prefix: "/users" }) // ✅ Will be /api/users
+```
+
+3. **Check server is running:**
+```bash
+curl http://localhost:3000/api/health # Should return status
+```
+
+#### Issue: CORS Errors in Development
+```bash
+# Error: Access to fetch at 'http://localhost:3000/api/users' from origin 'http://localhost:5173' has been blocked by CORS
+```
+
+**Solution:**
+Check Vite proxy configuration in `vite.config.ts`:
+```typescript
+export default defineConfig({
+ server: {
+ port: 5173,
+ proxy: {
+ '/api': {
+ target: 'http://localhost:3000',
+ changeOrigin: true,
+ secure: false,
+ }
+ }
+ }
+})
+```
+
+### Database and State Issues
+
+#### Issue: In-Memory Data Resets Unexpectedly
+```bash
+# Issue: Users/data disappearing during development
+```
+
+**Cause:** Hot reload resets in-memory data structures.
+
+**Solutions:**
+```typescript
+// app/server/controllers/users.controller.ts
+export class UsersController {
+ // Add persistence during development
+ static resetForTesting() {
+ users.splice(0, users.length)
+ // Add default data
+ users.push(
+ { id: 1, name: "João", email: "joao@example.com", createdAt: new Date() },
+ { id: 2, name: "Maria", email: "maria@example.com", createdAt: new Date() }
+ )
+ }
+}
+```
+
+**For Production:**
+1. Implement proper database integration
+2. Use persistent storage (SQLite, PostgreSQL, etc.)
+3. Add data migration scripts
+
+### Frontend Issues
+
+#### Issue: React Component Not Updating
+```bash
+# Issue: State changes not reflecting in UI
+```
+
+**Common Causes:**
+1. **Missing dependencies in useEffect:**
+```typescript
+// ❌ Missing dependency
+useEffect(() => {
+ loadUsers()
+}, []) // Should include dependencies
+
+// ✅ Correct dependencies
+useEffect(() => {
+ loadUsers()
+}, [loadUsers])
+```
+
+2. **State mutation instead of replacement:**
+```typescript
+// ❌ Direct mutation
+users.push(newUser)
+setUsers(users)
+
+// ✅ Create new array
+setUsers(prev => [...prev, newUser])
+```
+
+#### Issue: Import Path Errors
+```bash
+# Error: Module not found: Can't resolve '@/components/UserList'
+```
+
+**Path Alias Issues:**
+```typescript
+// ✅ Correct usage
+import { UserList } from '@/components/UserList' // Frontend component
+import type { User } from '@/shared/types' // Shared types
+import { api } from '@/lib/eden-api' // Frontend lib
+
+// ❌ Common mistakes
+import { User } from '@/app/shared/types' // Too specific
+import { UserList } from '../../components/UserList' // Relative path
+```
+
+### Testing Issues
+
+#### Issue: Tests Failing After Changes
+```bash
+# Error: Tests failing due to data isolation issues
+```
+
+**Solution - Add Test Data Reset:**
+```typescript
+// In your test files
+import { describe, it, expect, beforeEach } from 'vitest'
+import { UsersController } from '@/app/server/controllers/users.controller'
+
+describe('Users API', () => {
+ beforeEach(() => {
+ UsersController.resetForTesting() // ✅ Reset data between tests
+ })
+
+ it('should create user successfully', async () => {
+ const result = await UsersController.createUser({
+ name: 'Test User',
+ email: 'test@example.com'
+ })
+
+ expect(result.success).toBe(true)
+ })
+})
+```
+
+#### Issue: Vitest Configuration Errors
+```bash
+# Error: Test imports not resolving
+```
+
+**Check Vitest Config:**
+```typescript
+// vitest.config.ts
+import { defineConfig } from 'vitest/config'
+import react from '@vitejs/plugin-react'
+import { resolve } from 'path'
+
+export default defineConfig({
+ plugins: [react()],
+ test: {
+ globals: true,
+ environment: 'jsdom',
+ setupFiles: ['./tests/setup.ts']
+ },
+ resolve: {
+ alias: {
+ '@': resolve(__dirname, './app/client/src'),
+ '@/shared': resolve(__dirname, './app/shared'),
+ '@/core': resolve(__dirname, './core'),
+ // Add all your path aliases here
+ }
+ }
+})
+```
+
+### Performance Issues
+
+#### Issue: Slow Startup Times
+```bash
+# Issue: Development server taking too long to start
+```
+
+**Diagnostic Steps:**
+```bash
+# Measure startup time
+time bun run dev
+
+# Check for large dependencies
+bun pm ls --all | grep -E '\d+MB'
+
+# Profile the application
+bun --inspect app/server/index.ts
+```
+
+**Solutions:**
+1. **Remove unused dependencies**
+2. **Optimize imports** (avoid barrel exports)
+3. **Use dynamic imports** for large modules
+4. **Check for circular dependencies**
+
+#### Issue: High Memory Usage
+```bash
+# Issue: Memory usage growing over time
+```
+
+**Monitoring:**
+```typescript
+// Add memory monitoring
+app.get('/debug/memory', () => ({
+ memory: process.memoryUsage(),
+ uptime: process.uptime()
+}))
+```
+
+**Common Causes:**
+1. **Memory leaks in event listeners**
+2. **Uncleared timeouts/intervals**
+3. **Growing in-memory collections**
+4. **Circular references**
+
+### Debugging Tools and Techniques
+
+#### Debug Mode Configuration
+
+```typescript
+// app/server/index.ts
+if (process.env.NODE_ENV === 'development') {
+ // Enable debug routes
+ app.get('/debug/routes', () => app.routes)
+ app.get('/debug/config', () => app.getContext())
+ app.get('/debug/memory', () => process.memoryUsage())
+}
+```
+
+#### Logging Best Practices
+
+```typescript
+// Enhanced logging during development
+const logger = {
+ info: (message: string, data?: any) => {
+ if (process.env.NODE_ENV === 'development') {
+ console.log(`[INFO] ${message}`, data ? JSON.stringify(data, null, 2) : '')
+ }
+ },
+ error: (message: string, error?: any) => {
+ console.error(`[ERROR] ${message}`, error)
+ }
+}
+
+// Use in controllers
+export class UsersController {
+ static async createUser(userData: CreateUserRequest): Promise {
+ logger.info('Creating user', { userData })
+
+ try {
+ const result = await this.performCreate(userData)
+ logger.info('User created successfully', { user: result.user })
+ return result
+ } catch (error) {
+ logger.error('Failed to create user', error)
+ throw error
+ }
+ }
+}
+```
+
+#### Network Debugging
+
+```bash
+# Test API endpoints directly
+curl -X GET http://localhost:3000/api/health
+curl -X GET http://localhost:3000/api/users
+curl -X POST http://localhost:3000/api/users \
+ -H "Content-Type: application/json" \
+ -d '{"name":"Test","email":"test@example.com"}'
+
+# Check network requests in browser DevTools
+# Monitor Network tab for API calls
+# Check Console for errors
+```
+
+### Health Checks and Monitoring
+
+#### Application Health Check
+
+```typescript
+// app/server/routes/index.ts
+.get("/health", () => {
+ const health = {
+ status: "ok",
+ timestamp: new Date().toISOString(),
+ uptime: `${Math.floor(process.uptime())}s`,
+ version: "1.4.1",
+ environment: process.env.NODE_ENV || "development",
+ memory: process.memoryUsage(),
+ // Add more diagnostic info as needed
+ }
+
+ return health
+})
+```
+
+#### System Diagnostics
+
+```bash
+# Create diagnostic script
+# scripts/diagnose.ts
+console.log('FluxStack Diagnostics')
+console.log('==================')
+console.log('Node Version:', process.version)
+console.log('Bun Version:', process.env.BUN_VERSION)
+console.log('OS:', process.platform)
+console.log('Memory:', process.memoryUsage())
+console.log('Environment:', process.env.NODE_ENV)
+
+# Run diagnostics
+bun scripts/diagnose.ts
+```
+
+## Emergency Recovery Procedures
+
+### Complete Reset
+
+```bash
+# Nuclear option - complete reset
+rm -rf node_modules
+rm -f bun.lockb
+bun install
+
+# Reset development environment
+rm -rf dist/
+bun run build
+
+# Clear all caches
+bun pm cache rm
+```
+
+### Backup and Restore
+
+```bash
+# Backup current state
+cp -r app/ backup/app-$(date +%Y%m%d)/
+cp package.json backup/package-$(date +%Y%m%d).json
+
+# Restore from backup
+cp -r backup/app-20240101/ app/
+cp backup/package-20240101.json package.json
+bun install
+```
+
+### Configuration Verification
+
+```typescript
+// scripts/verify-config.ts
+import { resolve } from 'path'
+
+const configs = [
+ 'package.json',
+ 'vite.config.ts',
+ 'vitest.config.ts',
+ 'tsconfig.json'
+]
+
+console.log('Configuration Verification:')
+configs.forEach(config => {
+ const path = resolve(config)
+ try {
+ require(path)
+ console.log(`✅ ${config} - Valid`)
+ } catch (error) {
+ console.log(`❌ ${config} - Error:`, error.message)
+ }
+})
+```

+# FluxStack Monitoring Plugin
+
+The monitoring plugin provides comprehensive performance monitoring, metrics collection, and system monitoring for FluxStack applications.
+
+## Features
+
+- **HTTP Metrics**: Request/response timing, status codes, request/response sizes
+- **System Metrics**: Memory usage, CPU usage, event loop lag, load average
+- **Custom Metrics**: Counters, gauges, and histograms
+- **Multiple Exporters**: Console, Prometheus, JSON, and file exporters
+- **Alert System**: Configurable thresholds and alerts
+- **Metrics Endpoint**: Built-in `/metrics` endpoint for Prometheus scraping
+
+## Configuration
+
+```typescript
+// fluxstack.config.ts
+export default {
+ plugins: {
+ config: {
+ monitoring: {
+ enabled: true,
+ httpMetrics: true,
+ systemMetrics: true,
+ customMetrics: true,
+ collectInterval: 5000, // 5 seconds
+ retentionPeriod: 300000, // 5 minutes
+
+ exporters: [
+ {
+ type: "prometheus",
+ endpoint: "/metrics",
+ enabled: true,
+ format: "text"
+ },
+ {
+ type: "console",
+ interval: 30000,
+ enabled: false
+ },
+ {
+ type: "file",
+ filePath: "./logs/metrics.json",
+ interval: 60000,
+ enabled: true,
+ format: "json"
+ }
+ ],
+
+ thresholds: {
+ responseTime: 1000, // ms
+ errorRate: 0.05, // 5%
+ memoryUsage: 0.8, // 80%
+ cpuUsage: 0.8 // 80%
+ },
+
+ alerts: [
+ {
+ metric: "http_request_duration_ms",
+ operator: ">",
+ value: 2000,
+ severity: "warning",
+ message: "High response time detected"
+ },
+ {
+ metric: "process_memory_rss_bytes",
+ operator: ">",
+ value: 1000000000, // 1GB
+ severity: "error",
+ message: "High memory usage"
+ }
+ ]
+ }
+ }
+ }
+}
+```
+
+## Metrics Collected
+
+### HTTP Metrics
+- `http_requests_total` - Total number of HTTP requests
+- `http_responses_total` - Total number of HTTP responses
+- `http_errors_total` - Total number of HTTP errors
+- `http_request_duration_seconds` - HTTP request duration histogram
+- `http_request_size_bytes` - HTTP request size histogram
+- `http_response_size_bytes` - HTTP response size histogram
+
+### System Metrics
+- `process_memory_rss_bytes` - Process resident set size
+- `process_memory_heap_used_bytes` - Process heap used
+- `process_memory_heap_total_bytes` - Process heap total
+- `process_memory_external_bytes` - Process external memory
+- `process_cpu_user_seconds_total` - Process CPU user time
+- `process_cpu_system_seconds_total` - Process CPU system time
+- `process_uptime_seconds` - Process uptime
+- `nodejs_eventloop_lag_seconds` - Node.js event loop lag
+- `system_memory_total_bytes` - System total memory
+- `system_memory_free_bytes` - System free memory
+- `system_load_average_1m` - System load average (1 minute)
+
+## Exporters
+
+### Prometheus Exporter
+Exports metrics in Prometheus format. Can be configured to:
+- Serve metrics at `/metrics` endpoint (default)
+- Push metrics to Prometheus pushgateway
+
+### Console Exporter
+Logs metrics to console at specified intervals.
+
+### JSON Exporter
+Exports metrics in JSON format to:
+- HTTP endpoint (POST request)
+- Console logs
+
+### File Exporter
+Writes metrics to file in JSON or Prometheus format.
+
+## Usage
+
+The monitoring plugin is automatically loaded and configured through the FluxStack plugin system. Once enabled, it will:
+
+1. Start collecting system metrics at the configured interval
+2. Record HTTP request/response metrics automatically
+3. Export metrics according to the configured exporters
+4. Monitor alert thresholds and log warnings/errors
+
+## Accessing Metrics
+
+### Prometheus Endpoint
+Visit `http://localhost:3000/metrics` (or your configured endpoint) to see Prometheus-formatted metrics.
+
+### Programmatic Access
+```typescript
+import { MetricsCollector } from 'fluxstack/core/utils/monitoring'
+
+const collector = new MetricsCollector()
+
+// Create custom metrics
+const myCounter = collector.createCounter('my_custom_counter', 'My custom counter')
+myCounter.inc(1)
+
+const myGauge = collector.createGauge('my_custom_gauge', 'My custom gauge')
+myGauge.set(42)
+
+const myHistogram = collector.createHistogram('my_custom_histogram', 'My custom histogram')
+myHistogram.observe(1.5)
+
+// Get system metrics
+const systemMetrics = collector.getSystemMetrics()
+console.log('Memory usage:', systemMetrics.memoryUsage)
+
+// Export metrics
+const prometheusData = collector.exportPrometheus()
+console.log(prometheusData)
+```
+
+## Alert Configuration
+
+Alerts can be configured to monitor specific metrics and trigger notifications when thresholds are exceeded:
+
+```typescript
+alerts: [
+ {
+ metric: "http_request_duration_ms",
+ operator: ">",
+ value: 2000,
+ severity: "warning",
+ message: "High response time detected"
+ },
+ {
+ metric: "process_memory_rss_bytes",
+ operator: ">",
+ value: 1000000000, // 1GB
+ severity: "error",
+ message: "High memory usage"
+ }
+]
+```
+
+Supported operators: `>`, `<`, `>=`, `<=`, `==`, `!=`
+Supported severities: `info`, `warning`, `error`, `critical`
+
+## Requirements Satisfied
+
+This monitoring plugin satisfies the following requirements:
+
+- **7.1**: Collects basic metrics (response time, memory usage, etc.)
+- **7.2**: Provides detailed performance logging with timing
+- **7.3**: Identifies performance problems through thresholds and alerts
+- **7.4**: Includes basic metrics dashboard via `/metrics` endpoint
+- **7.5**: Supports integration with external monitoring systems (Prometheus, etc.)
