webpage-rendering

Before displaying the items from a collection, meteor seems to do some processing that leaves the client window without updates. You can see this live if you surf to http://madewith.meteor.com on a reasonable machine. My 2.6GHz 4GB RAM laptop takes about 5 seconds to render the items in the list, during which there is no indication of progress and a new user in a hurry could reasonably believe the page has finished loading. Is there a way to incrementally display items from a collection, such that the server pushes to the client the first items of data on the wire, and the browser renders them

My question is about Chrome DevTools, specifically I have question about Timeline tab. So as I've read numerous times, my browser has to have 60fps speed rendering my pixels. Sometimes though it has some heavy JS executing and preventing 60fps happening. Also if I have some CSS and JS which cause recalculating and repainting of the DOM tree(part or full tree) it may also take more than ~16ms for one frame. Here is the picture of such a long frame from our app: Ok, here I can clearly see, that two requests take so much time(192ms + 14ms), that browser can't paint 60fps and it doesn't get even

I have set up a script to create webshots of our app. It runs perfectly and all is fine Until I encounter an image with a broken url : "<img src='http://testserver.our.intranet/fetch/image/373e8fd2339696e2feeb680b765d626e' />" I have managed to break the script after 6 seconds using the below, Before it was just looping forever. But, is it possible to ignore the network request ( AKA take the image out of DOM ) and then proceed to create the thumb without the image, (or with an injected image missing image !) var page = require('webpage').create(), system = require('system'), address, output,

I am using the new page renderer from TYPO3 8 on controller level to add extension specific css and js files via an initializeAction: public function initializeAction() { $extPath = ExtensionManagementUtility::siteRelPath( $this->request->getControllerExtensionKey() ); $extJs = $extPath . 'Resources/Public/Js/ext_booking_manager.min.js'; $extCss = $extPath . 'Resources/Public/Css/ext_booking_manager.css'; /** @var PageRenderer $pageRenderer */ $pageRenderer = $this->objectManager->get(PageRenderer::class); $pageRenderer->addCssFile($extCss); $pageRenderer->addJsFooterFile( $extJs, 'text
