How to Build a Blog Engine in Go

You build a Go blog engine by initializing a module, creating an HTTP handler to serve posts, and running the server.

1. Initialize the module and create the main file. go mod init blog && touch main.go

2. Add the HTTP handler code to main.go to serve a static "Hello" page. `cat > main.go << 'EOF' package main

import ( "fmt" "net/http" )

func main() { http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) { fmt.Fprintf(w, "Hello, Blog!") }) http.ListenAndServe(":8080", nil) } EOF`

3. Run the server to start your blog engine. go run main.go

Building a blog engine in Go starts by setting up a basic web server that responds to browser requests. It creates a project folder, writes a small program that listens for traffic on port 8080, and starts it up. Think of it like setting up a digital storefront where your code is the shopkeeper greeting visitors.
