How to Use go

Use the //go:embed directive to embed files directly into your binary at compile time. Place the directive above a variable declaration, specifying the file path pattern relative to the source file.

package main

import "embed"

//go:embed templates/*.html
var TemplateFS embed.FS

func main() {
    // TemplateFS now contains all .html files in the templates directory
}

This creates a read-only filesystem (embed.FS) that you can use with html/template or io/fs to read files without needing external assets.

go:embed lets you pack your template files directly inside your program's executable file. Instead of your program looking for files on the computer's hard drive, it reads them from its own memory. It's like putting a book inside a box so you never have to worry about losing the book.
