How to Use go

Use the //go:embed directive to embed files directly into your Go binary at compile time. Place the directive immediately before a variable declaration to bind the file path to that variable.

package main

import "embed"

//go:embed data.txt
var content string

func main() {
    // content now holds the file data
}

This approach compiles the file content into the executable, eliminating the need for external file dependencies at runtime.

go:embed lets you pack files like images or config data directly inside your program's executable file. Instead of your app needing to find these files on a disk when it runs, they are already built-in. It is like putting a letter inside an envelope before mailing it, so the recipient gets everything in one package.
