Learning Go by Making a Game: Embedded Assets

One of the more delightful features of Go that I’ve discovered is the embed package which is a combination of compiler directive and standard library. With the embed package, project resources are bundled into the binary and assigned to the annotated struct field. For example from their docs:

import _ "embed"

//go:embed hello.txt
var s string

print(s)

To embed all files with the package, you can use a glob expression on an embed.FS:

//go:embed *
var assetsFS embed.FS

data, _ := assetsFS.ReadFile("hello.txt")

Really useful for loading internal game assets!
