Basic Router engine usage with gin

After calling app.InitializeLite() or app.Initialize() (basically your first line of code in your main) you can access the gin.Engine object through ginServer.Router export and use it to add your own routes.

Example:

package main

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

	"github.com/DanielRenne/GoCore/core/app"
	"github.com/DanielRenne/GoCore/core/extensions"
	"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))
	}
}
