Package Exports

express-raw
express-raw/src/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (express-raw) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

🚀 Quick Start

const express = require('express');
const { 
    expressLogger, 
    RateLimiter,
    WebSocketSupport,
    MetricsDashboard 
} = require('express-raw');

const app = express();

Rate Limiting

Configuration Options

const limiter = new RateLimiter({
    // Time Window
    windowMs: 15 * 60 * 1000,  // 15 minutes
    maxRequests: 100,
    windowType: 'sliding',     // 'sliding' | 'fixed'
    
    // Route Limits
    routeLimits: {
        '/api/auth/.*': 20,    // Auth routes: 20 req/window
        '/api/upload/.*': 10   // Upload routes: 10 req/window
    },
    
    // Security
    autoBan: {
        enabled: true,
        maxViolations: 3,      // Ban after 3 violations
        banDurationMs: 24 * 60 * 60 * 1000 // 24h
    }
});

Enhanced Logging

Configuration & Examples

const logger = new expressLogger({
    enabled: {
        server: true,      // Server logs
        requests: true,    // Request logs
        responses: true,   // Response logs
        websocket: true,   // WebSocket logs
        graphql: true      // GraphQL logs
    }
});

Output Examples

# Server Start
[2024-11-25T19:38:20.177Z] ⚡ [SERVER] Server started
    Port: 3000
    Environment: development
    Memory: 8MB

# Rate Limit Event
[2024-11-25T19:38:26.177Z] ⚠️ [RATELIMIT] Rate limit exceeded
    IP: 192.168.1.100
    Path: /api/users
    ViolationCount: 1

WebSocket Support

const wsSupport = new WebSocketSupport({
    heartbeatInterval: 30000,
    rateLimiting: {
        enabled: true,
        maxConnectionsPerIP: 5
    },
    auth: {
        enabled: true,
        handler: async (req) => {
            // Auth logic
        }
    }
});

// Broadcast
wsSupport.broadcast({ type: 'update', data: { time: Date.now() }});

GraphQL Integration

const profiler = new GraphQLProfiler({
    slowQueryThreshold: 500,    // ms
    maxQueryComplexity: 100,
    maxDepth: 10,
    trackMemory: true
});

app.use('/graphql', profiler.middleware(logger));

Metrics Dashboard

const dashboard = new MetricsDashboard({
    updateInterval: 5000,
    enableRealtime: true,
    alerts: {
        maxMemoryUsage: 85,     // %
        maxErrorRate: 3         // %
    }
});

🎯 Examples

Complete Application Example

const express = require('express');
const { 
    expressLogger, 
    RateLimiter,
    WebSocketSupport,
    GraphQLProfiler,
    MetricsDashboard
} = require('express-raw');

const app = express();

// Initialize components
const logger = new expressLogger({
    enabled: { 
        rateLimit: true, 
        websocket: true,
        graphql: true 
    }
});

const limiter = new RateLimiter({
    windowMs: 15 * 60 * 1000,
    maxRequests: 100,
    autoBan: { enabled: true }
});

const wsSupport = new WebSocketSupport({
    rateLimiting: { enabled: true }
});

const profiler = new GraphQLProfiler({
    slowQueryThreshold: 500
});

const dashboard = new MetricsDashboard({
    enableRealtime: true
});

// Apply middleware
app.use(limiter.middleware(logger));
app.use(logger.middleware());
app.use('/graphql', profiler.middleware(logger));
app.use(dashboard.middleware(logger, limiter, profiler));

// Start server
const server = app.listen(3000, () => {
    logger.serverStart(3000);
});

wsSupport.middleware(logger)(server);

📋 Best Practices

Rate Limiting

Use sliding windows
Set route-specific limits
Enable auto-ban for security
Whitelist trusted IPs

WebSocket

Enable heartbeat
Implement authentication
Set connection limits
Handle reconnection

GraphQL

Set complexity limits
Monitor slow queries
Implement depth limiting
Cache common queries

Dashboard

Set alert thresholds
Monitor memory trends
Keep reasonable retention
Adjust update frequency

🔧 Troubleshooting

Common Issues & Solutions

Rate Limiter

// Fix: Too many false positives
const limiter = new RateLimiter({
    windowType: 'sliding',
    maxRequests: 200
});

// Fix: Auto-ban too aggressive
const limiter = new RateLimiter({
    autoBan: {
        maxViolations: 5,
        banDurationMs: 60 * 60 * 1000
    }
});

WebSocket

// Fix: Connection drops
const wsSupport = new WebSocketSupport({
    heartbeatInterval: 15000
});

// Fix: Memory leaks
const dashboard = new MetricsDashboard({
    retentionPeriod: 3600000,
    cleanup: true
});
