This project demonstrates a basic web server in Go that uses handlers, renders templates, and serves HTML pages. The project structure includes a main entry point, handler functions, and a template rendering utility.

This is the entry point of the application. It sets up the HTTP server and routes.
package main
import (
"fmt"
"log"
"main/pkg/handlers"
"net/http"
)
const portNumber = ":8000"
func main() {
http.HandleFunc("/", handlers.Home)
http.HandleFunc("/about", handlers.About)
fmt.Println(fmt.Sprintf("Starting server on port %s", portNumber))
if err := http.ListenAndServe(portNumber, nil); err != nil {
log.Fatal(err)
}
}This file contains the template rendering logic. It parses and executes HTML templates.
package render
import (
"fmt"
"html/template"
"net/http"
)
func RenderTemplate(w http.ResponseWriter, tmpl string) {
parsedTemplate, _ := template.ParseFiles("./templates/" + tmpl)
err := parsedTemplate.Execute(w, nil)
if err != nil {
fmt.Println("Error Parsing template: ", err)
return
}
}This file contains the handler functions for different routes.
package handlers
import (
"main/pkg/render"
"net/http"
)
func Home(w http.ResponseWriter, r *http.Request) {
render.RenderTemplate(w, "home.page.tmpl")
}
func About(w http.ResponseWriter, r *http.Request) {
render.RenderTemplate(w, "about.page.tmpl")
}This is the HTML template for the home page.

</html>- Ensure you have Go installed on your machine.
- Clone the repository or copy the project structure to your local machine.
- Navigate to the project directory.
- Run the application using the following command:
go run main.go- Open your web browser and navigate to
http://localhost:8000to see the home page. - Navigate to
http://localhost:8000/aboutto see the about page.
This project provides a simple experience for me of how to set up a basic web server in Go with handlers, template rendering, and HTML templates. You can expand this project by adding more routes, templates, and functionality as needed.
