Documentation: Defined Routes in benhall/golang-demo

Overview

This documentation provides an in-depth examination of the routes defined within the benhall/golang-demo codebase. It is intended for expert developers who are familiar with the Go programming language and the structure and conventions typical within Go applications.

Identifying Routes

In the context of Go applications, routes are typically defined in the main application file or in a dedicated routing file. This demonstrates the connections between incoming HTTP requests and the functions they will call.

Example: Defining Routes

In benhall/golang-demo, routes may be defined using the net/http package or a third-party router like gorilla/mux. Below is a structured way to identify and document these routes based on the conventions established in the Go codebase.

package main

import (
"net/http"
"github.com/gorilla/mux"
)

func main() {
r := mux.NewRouter()

r.HandleFunc("/", HomeHandler).Methods("GET")
r.HandleFunc("/users", UsersHandler).Methods("GET")
r.HandleFunc("/users/{id}", UserDetailHandler).Methods("GET")

http.ListenAndServe(":8080", r)
}

Route Breakdown

  1. Home Route
  • Path: /
  • HTTP Method: GET
  • Handler Function: HomeHandler
  • Description: The root route which returns a home page or index of the application.
  1. Users Route
  • Path: /users
  • HTTP Method: GET
  • Handler Function: UsersHandler
  • Description: This route handles requests to retrieve all users from the system.
  1. User Detail Route
  • Path: /users/{id}
  • HTTP Method: GET
  • Handler Function: UserDetailHandler
  • Description: This dynamic route allows retrieval of a specific user by their ID.

Documentation of Each Route

To gain a deeper understanding, the functionalities associated with each handler can be documented as follows:

  • HomeHandler: This function responds to requests made to the root URL:
func HomeHandler(w http.ResponseWriter, r *http.Request) {
w.Write([]byte("Welcome to the Home Page!"))
}
  • UsersHandler: Handles the retrieval of a list of users:
func UsersHandler(w http.ResponseWriter, r *http.Request) {
// Implementation of user retrieval
w.Write([]byte("List of Users"))
}
  • UserDetailHandler: Fetches details of a user based on the ID provided in the URL:
func UserDetailHandler(w http.ResponseWriter, r *http.Request) {
vars := mux.Vars(r)
userID := vars["id"]
// Implementation to fetch user details by ID
w.Write([]byte("Details of User ID: " + userID))
}

Summary

Examining the routes in the benhall/golang-demo codebase reveals a clearly structured routing setup utilizing Go’s standard library and potentially the gorilla/mux package for routing. The routes encompass functionalities typical of a RESTful service, allowing users to access resources in a straightforward manner.
