Often you just need to reference files with paths. Use filepath.Join for cross-platform import "path/filepath" path := filepath.Join("data", "users", "profile.json") Get executable directory (to find linked assets) exePath, _ := os.Executable() dir := filepath.Dir(exePath) configPath := filepath.Join(dir, "configs", "app.yaml") Go module-aware paths (for testdata) // In a test: paths are relative to test file data, _ := os.ReadFile("testdata/input.txt") 5. Go generate – Link code generation to files Use //go:generate to run tools that transform external files into Go code. go file links
This is the most common "file link" in modern Go—it links external files into your executable at compile time. Basic usage package main import _ "embed" func main() data, _ := staticFiles
//go:embed logo.png var logoBytes []byte func main() data
