How to implement iframe without refreshing after route switching

You would have to define deactivate and activate lifecycle methods for keep-alive to work.
But the problem is, Vue detach this component from DOM and when that happens the iframe loses its state. So the solution would be to probably attach the iframe to somewhere else in the DOM and apply display:none when deactivate() is called. And then attach it back on activate()
