Now AMP Runs Scripts ⇥ blog.amp.dev

Google’s AMP Project has announced that the platform will now run arbitrary site-defined scripts in a special <amp-script> tag, albeit with some caveats: scripts are limited to 150 KB each, and redrawing after the page has loaded isn’t possible without a precipitating user action. It says that this is to preserve the speed of an AMP page, and I believe this argument — generally, the less bytes a page transfers, the faster it is. This follows the project’s recent announcement of sending markup to client browsers instead of unpacking pages with a required 100 KB JavaScript file.

The AMP team has not yet confirmed a date at which it expects to entirely replicate HTML in its proprietary language, but all signs point to Google continuing to use its influence to coax publishers into running a second version of their websites entirely tailored for the company’s needs.
