GoCore Lite

Create a main.go

package main

import (
	"mime"
	"os"
	"os/signal"
	"path"
	"time"

	"github.com/DanielRenne/GoCore/core/app"

	"github.com/DanielRenne/GoCore/core/ginServer"
	"github.com/gin-gonic/gin"
)

func addSecureHeaders(c *gin.Context) {
	c.Writer.Header().Set("Strict-Transport-Security", "max-age=63072000; includeSubDomains; preload")
	c.Writer.Header().Set("X-Content-Type-Options", "nosniff")
	c.Writer.Header().Set("X-Frame-Options", "SAMEORIGIN")
	serve_SSL_only := os.Getenv("SERVE_SSL_ONLY")
	if serve_SSL_only == "true" {
		c.Writer.Header().Set("Content-Security-Policy", "default-src https: 'unsafe-eval' 'unsafe-inline'; font-src 'self' data: https:; img-src 'self' blob: data: https:;media-src 'self' blob: data: https:; object-src 'self' blob: data: https; connect-src 'self' wss: https:")
	}
	c.Writer.Header().Set("X-XSS-Protection", "1")
}

func main() {
	port := os.Getenv("PORT")
	app.InitializeLite(false, []string{})

	ginServer.Router.NoRoute(func(c *gin.Context) {
		addSecureHeaders(c)
		c.JSON(404, gin.H{"code": "PAGE_NOT_FOUND", "message": "Page not found"})
	})

	ginServer.Router.GET("/", func(c *gin.Context) {
		addSecureHeaders(c)
		var data []byte
		data = append(data, []byte("log.Println('Hello GoCore Lite');")...)
		// Possibly read assets like an index.html template through the use of an awesome project https://github.com/go-bindata/go-bindata which compiles all assets into your go binary.
		// data, err := assets.Asset("web/dist/index.html")
		// if err != nil {
		// 	ginServer.RenderHTML("Error: "+err.Error(), c)
		// 	return

		ext := path.Ext(c.Request.URL.String())

		c.Writer.Header().Set("Content-Type", mime.TypeByExtension(ext))
		c.Writer.Header().Set("Content-Length", extensions.IntToString(len(data)))

		ginServer.RespondJSFile(data, time.Now(), c)

	})

	if port == "" {
		go app.RunLite(80)
		c := make(chan os.Signal, 1)
		signal.Notify(c, os.Interrupt, os.Kill)
		<-c
	} else {
		app.RunLite(extensions.StringToInt(port))
	}
}

Then run go build main.go && ./main
