In Go 1.16 version, using package "embed" we can easily embed files in Go programs.

The embed file content variable should be of type string, []byte, or FS only.

package main

import _"embed"


func main() {
	//go:embed "hello.txt"
	var s string
	print(s)
}

And running the program using beta version of Go 1.16.

go1.16beta1 run embed-file.go

//OUTPUT
Hello, Gophers!

Reading file content in bytes format.

//go:embed "hello.txt"
var b []byte
print(string(b))

To read the file contents in embed.FS format use the below code snippet.

//go:embed hello.txt
var f embed.FS
data, _ := f.ReadFile("hello.txt")
print(string(data))
