Idea for SPA server instead of NGINX - Dorel IO

dorel-io-static-server.go

/**
 * Idea for SPA server instead of NGINX - Dorel IO
 *
 * You can run this locally: `$ go run dorel-io-static-server.go`
 * The concept is that the Wordpress API is asked if the page exsists, if yes, it sends the correct meta data and status code.
 * If you try: localhost:8080/foobar you will get a 404
 * If yountry: localhost:8080/about-us (or another exsisting page) you will get a 200 with the correct metadata
 *
 * Bower compontents is always skipped and shown.
 *
 * Writtin this in Go because it will scale for production
