Angular2页面渲染

Question

How is the page in the Angular2 is rendered? Does it render all the DOM elements that might be used at the page, for example pop-up, dialog? Or does it render after the element is being invoked?

Answer 1

For angular 2 when you spin up a server it loads all the html templates lazily. The index.html page is the entry point and by default the app-root directive is loaded first. If you have say another component featureA and featureB that are triggered by clicking a button or some other UI element those aren't loaded until you actually click on it.
