How to use statigz with gin?

Copied from #12 for better visibility.

Gin's standard StaticFS is not suitable, because it operates on file system level and misses enough control to directly substitute compressed assets. However you can mount statigz as regular http.Handler.

package main

import (
	"embed"
	"io/fs"
	"log"
	"net/http"

	"github.com/gin-gonic/gin"
	"github.com/vearutop/statigz"
)

// Declare your embedded assets.

//go:embed assets/*
var st embed.FS

func main() {
	s, err := fs.Sub(st, "assets")
	if err != nil {
		log.Fatal(err)
	}

	router := gin.Default()
	
	ss := http.StripPrefix("/static", statigz.FileServer(s.(fs.ReadDirFS)))

	router.GET("/static/*w", func(c *gin.Context) {
		ss.ServeHTTP(c.Writer, c.Request)
	})

	if err := router.Run(":8080"); err != nil {
		log.Fatal(err)
	}
}

Or, if your embedding path matches http path, even simpler.

package main

import (
	"embed"
	"log"

	"github.com/gin-gonic/gin"
	"github.com/vearutop/statigz"
)

// Declare your embedded assets.

//go:embed static/*
var st embed.FS

func main() {
	router := gin.Default()
	ss := statigz.FileServer(st)

	router.GET("/static/*w", func(c *gin.Context) {
		ss.ServeHTTP(c.Writer, c.Request)
	})

	if err := router.Run(":8080"); err != nil {
		log.Fatal(err)
	}
}
