HTTP Server Template

A complete REST API server demonstrating:

• http_server() - Create and configure a server
• route() - Register endpoint handlers
• context() - Access request/response data
• JSON APIs - Serve structured data
• Error handling - Try/catch for robustness
• Query parameters - Parse and use request data

Running

duso http-server.du

Then in another terminal:

# Home page
curl http://localhost:8080/

# JSON greeting
curl "http://localhost:8080/api/hello?name=Alice"

# Echo endpoint
curl -X POST http://localhost:8080/api/echo \
  -H "Content-Type: application/json" \
  -d '{"message": "Hello, Duso!"}'

Structure

• http-server.du - Server setup and route registration

  • home.du - HTML home page
  • hello.du - JSON greeting with query params
