Single Page App File Service

Often Single Page Apps (SPA) that keep history use the URl path to track the location in the application. When people refresh a page or use a bookmark in the browser this leads to paths like https://example.com/login that should serve the index.html page but instead result in 404 errors.

This middleware allows for a list of different paths that can be remapped to index.html or other files. Files that are legitimately missing will still be returned as 404 errors - but items in the list will remapped to a specified file (usually index.html).

example

package main

import (
	"os"

	"github.com/gin-gonic/gin"
	spa "github.com/pschlump/gin-spa"
)

func main() {
	r := gin.Default()
	pathsToRemap = map[string]string{
		"/login": "/index.html",
		"/logout": "/index.html",
	}
	r.Use(spa.StaticServeMiddleware("/", "./build", pathsToRemap, os.Stderr)) // your build of React or other SPA
	r.Run()
}
