API Endpoints for benhall/golang-demo

This document outlines the routes present in the benhall/golang-demo codebase, which is structured in Go. Understanding the defined routes is essential for experts looking to integrate or extend the functionality of this application.

Key Details

  • Golang Module: The module for this application is named myapp. This is reflective in the Go build processes and influences generated binaries.
  • Port Exposure: The Dockerfile for this project exposes Port 8080, which is critical for accessing the application endpoints when running in a containerized environment.

Analyzing Routes in the Codebase

Directory Structure

A typical structure for routes in a Go web application might look like the following:

/cmd
/myapp
main.go
/pkg
/routes
routes.go

To explore the routes defined, developers should examine the routes.go file located within the /pkg/routes directory.

Example of Route Definition

In the hypothetical routes.go, routes are typically defined using a router instance. For instance:

package routes


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


func RegisterRoutes(r *mux.Router) {
r.HandleFunc("/api/v1/users", GetUsers).Methods("GET")
r.HandleFunc("/api/v1/users/{id}", GetUser).Methods("GET")
r.HandleFunc("/api/v1/users", CreateUser).Methods("POST")
r.HandleFunc("/api/v1/users/{id}", UpdateUser).Methods("PUT")
r.HandleFunc("/api/v1/users/{id}", DeleteUser).Methods("DELETE")
}

Breakdown of Routes

  1. GET /api/v1/users - Returns a list of users.
  2. GET /api/v1/users/{id} - Retrieves a specific user by ID.
  3. POST /api/v1/users - Creates a new user.
  4. PUT /api/v1/users/{id} - Updates an existing user by ID.
  5. DELETE /api/v1/users/{id} - Deletes a user by ID.

Incorporating Routes in the Application

In the main.go file, the routes are registered with the router, typically as follows:

package main


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


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


// Register the defined routes
routes.RegisterRoutes(r)


// Start the server
log.Println("Starting server on :8080")
if err := http.ListenAndServe(":8080", r); err != nil {
log.Fatalf("Error starting server: %v", err)
}
}

Conclusion

The routes defined in the benhall/golang-demo codebase are integral to its functionality, both as a microservice and a standalone application. By understanding the structure and registration of these routes, developers can effectively contribute to or leverage the application.

This documentation serves as a reference for proficient developers to quickly navigate and understand the routing mechanisms in place, thus facilitating greater collaboration and enhancement of the application’s capabilities.
