Exactly how AMP functions. Each optimizations that is following have always been the reason why AMP web web pages are so quick these may actually load immediately

You can find seven grounds as a whole: however when that is always a lot to browse, just view that the explainer video clip:

Execute each AMP JavaScript asynchronously

JavaScript are mighty, it could change pretty much every facet of the web web page, however it also can block DOM construction as well as wait web web web page making (find out interactivity that is also adding JavaScript). To help keep JavaScript at delaying web page making, AMP permits exclusive asynchronous JavaScript.

AMP elements might posses JavaScript beneath the bonnet, then again they’re completely built to be sure that they do not trigger show degradation.

Even though customized JS is actually permitted as part of amp-script, as well as third-party JS was granted as part of iframes, this can not block making. For instance, if third-party JS makes use of that the super-bad-for-performance document. Write API, it generally does not block making that the page that is main.

Measured each means statically

Outside resources such as for example photos, advertisements otherwise iframes need state his or her shape inside HTML in order that AMP might find out every element’s measured as well as position prior to means is installed. AMP plenty each design of web web page minus looking forward to a resources in order to down load.

AMP uncouples document design at site design. Just one HTTP demand is necessary to design your doc that is entire+fonts). As AMP was fine tuned to avoid high priced design recalculations as well as designs within the internet browser, here won’t get all re-layout after means load.

Do not let expansion mechanisms block making

AMP does not enable expansion mechanisms block web web page making. AMP aids extensions concerning such things as lightboxes, instagram embeds, twitter posts, and so forth. Those requests do not block page layout and rendering while these require additional HTTP requests.
