To create a backend, you can follow the example provided in the Cloudflare documentation. According to the documentation, you can create a simple Golang backend that returns a hard-coded list of widgets. Here's an example code snippet in Golang that defines a backend container:

package main

import (
	"encoding/json"
	"log"
	"net/http"
)

func handler(w http.ResponseWriter, r *http.Request) {
	widgets := []map[string]interface{}{
		{"id": 1, "name": "Widget A"},
		{"id": 2, "name": "Sprocket B"},
		{"id": 3, "name": "Gear C"},
	}
	w.Header().Set("Content-Type", "application/json")
	w.Header().Set("Access-Control-Allow-Origin", "*")
	json.NewEncoder(w).Encode(widgets)
}

func main() {
	http.HandleFunc("/api/widgets", handler)
	log.Fatal(http.ListenAndServe(":8080", nil))
}

This code defines a handler function that returns a JSON response with a list of widgets. The main function sets up an HTTP server that listens on port 8080 and handles requests to the /api/widgets endpoint.

You can also use other frameworks and languages to create a backend, such as HonoX, which is a meta-framework for creating full-stack websites and Web APIs. To use HonoX, you can run the hono-create command and follow the setup process.
