Echo Go Web

Echo is a lightweight, high-performance web framework written in Go. It provides routing, middleware, request/response binding, validation, and middleware chains. Echo is built on Go's standard net/http but abstracts away boilerplate. A typical Echo service: define routes (GET /users/:id), handlers (fetch user from database, return JSON), middleware (logging, authentication), then server.ListenAndServe(). Developers can build REST APIs, microservices, or full web servers.
