Embedding Files in Gin

I read this quick article on that mentioned embedding static files in a Go binary. Indeed, Go did recently add this feature for static file embed. I think this is a super cool feature for a language to have. Your server, all your go code, all assets, and an entire frontend web app, all bundled up into one static binary! I love it.

However, there were a few issues with the original example snippet given in that article.

  • It can only serve files in the first level of the directory
  • It doesn’t work directly with Gin
  • If you do take this approach in Gin directly, you have collisions with the /*filepath and your API routes

Eventually, after much digging, I found this issue on the library for Gin’s static middleware that helped me resolve my issue: gin-contrib/static#19.

In the end, my server entrypoint looks something like this:

func main() {
	fmt.Println("Starting Server")
	router := gin.Default()
	router.Use(static.Serve("/", EmbedFolder(embeddedFiles, "client/build")))
	router.Group("/api").GET("/hello", getHello)
