Web Service Example

HTTP web service with automatic service discovery and registration.

What It Does

This example creates an HTTP service that:

• Serves RESTful API endpoints
• Registers with service discovery
• Provides health checks
• Uses standard Go HTTP handlers

Run It

go run main.go

Test It

# Get service info
curl http://localhost:9090/

# List all users
curl http://localhost:9090/users

# Get specific user
curl http://localhost:9090/users/1

# Health check
curl http://localhost:9090/health

Key Features

• Standard HTTP: Use familiar http.Handler interface
• Service Discovery: Automatically registers with registry
• Health Checks: Built-in health endpoint
• JSON APIs: Easy REST API development

When to Use

Use web.Service when:

• Building REST APIs
• Serving web UIs
• Working with HTTP-specific features
• Migrating existing HTTP services

Use regular micro.Service when:

• Building RPC services
• Need bidirectional streaming
• Want automatic load balancing
• Prefer structured RPC over HTTP
