Advanced Middleware Patterns

Master complex middleware architectures with μλην's distributed processing and observability features.

Middleware Composition

μλην's middleware system allows for advanced composition using declarative rules and conditional execution.

λλ middleware:create auth
λλ middleware:create logging
λλ middleware:compose --if=auth --then=logging

Create modular middleware components and compose them using logic gates.

Distributed Middleware

Leverage μλην's distributed middleware capabilities for load balancing and fault tolerance.

const distributedPipeline = mlhn.Middleware.distribute({
  workers: 5,
  strategy: 'least_connections',
  fallback: () => {
    return http.STATUS(503).json({ error: 'Service Unavailable' })
  }
})

app.use('/api', distributedPipeline)

Automatically scales middleware execution with built-in load balancing.

Observability Patterns

Monitor middleware performance with real-time metrics and distributed tracing.

λλ middleware:visualize --format=dot --output=flow.dot
λλ dashboard:open observability

Generate execution flow diagrams and launch built-in telemetry dashboards.

Policy-based Middleware

Implement dynamic policies using μλην's declarative language:

{ "execute": "rate_limiter", "when": { "request.header.client": "gold" } }

Circuit Breaker

Automatic failure detection for middleware chains:

λλ middleware:protect --threshold=5 --window=1m
