Reload the page without reloading the page (uses Fetch API and ES6)

reload.js

fetch(window.location.href).then(res =>
	res.text().then(text => {
		let domParser = new DOMParser()
		let newDoc = domParser.parseFromString(text, res.headers.get('Content-Type').split(';')[0])
		let newNode = document.importNode(newDoc.documentElement, true)
		document.replaceChild(newNode, document.documentElement)
	})
)
