A New Rendering Engine For Chromium – Hello Blink!

chromiumchrome_normal.pngBlink? Well, it’s a new rendering engine for Chromium with a big mission statement: “To improve the open web through technical innovation and good citizenship” 

Why is Chrome spawning a new browser engine?

There are two main reasons:

  • The main reason is that Chromium uses a different multi-process architecture than other WebKit-based browsers. So, over the years, supporting multiple architectures has led to increasing complexity for both the WebKit and Chromium communities, slowing down the collective pace of innovation.

  • In addition, this gives an opportunity to do open-ended investigations into other performance improvement strategies. We want web applications to be as fast as possible. So for example, we want to make as many of the browser’s duties run in parallel (think iframes!), so we can keep the main thread free for your application code. We’ve already made significant progress here, for example by reducing the impact JavaScript and layout has on page scrolling, and making it so an increasing number of CSS animations can run at 60fps even while JavaScript is doing some heavy-lifting.

If you wish to understand better this new story I would recommend you to read Alex Russell excellent post on it: http://infrequently.org/2013/04/probably-wrong/ and for the ones the like (even more) details: The Developer FAQ contain more.

HTML5 And Google App Script

App scriptIn our GDL-IL today, I’ve talked about a fun project I did in the past. It’s a single web page application that let you manage an event. We covered some of the basic components we used in order to built this site and then we jumped into the app script code and showed how to work with the online IDE that let you write, run and debug your server side code. The site gives you basic functions like: Continue reading

Chrome Extension For Enterprise Internal Usage

Chrome ExtensionsAt the beginning of the year, I’ve worked with a big organization that wanted to avoid the automatic suggestions Chrome is making in the omnibox (=the top field in Chrome, where you type searches and see the url).

Their main requirement was the need to allow employees to type a word and get the internal site that they are use to see. For example, the user will type ‘sale’ and Chrome will redirect them to the internal portal of sales. If you won’t modify Chrome it will run a google search on ‘sale’ and the results will be something like:

The good news is that with this little extension you will be able to control the redirect of the users to the right internal location. Let’s jump into code.

This is the code of our manifest file that describe the extension


{
"name": "Omnibox customization example",
"description" : "To use, type 'get' plus a search term into the Omnibox.",
"version": "1.1",
"background": {
"scripts": ["background.js"]
},
"omnibox": { "keyword" : "get" },
"manifest_version": 2
}

Important to notice is that we setting the keyword ‘get’ in order to activate this extension. You can choose something shorter if you like. Another aspect is the “manifest_version”: 2 which making sure we are compatible with the latest spec.

This is the code of our background page


// each time the user updates the text in the omnibox this event
// is fired and we will use it to suggest search terms for
// our internal users.
chrome.omnibox.onInputChanged.addListener(
function(text, suggest) {
suggest([
{content: "CRM" , description: " fetch the internal CRM"},
{content: "ERP" , description: " fetch the internal ERP"},
{content: "sales", description: " fetch the lastest sales report"}
]);
});
// This event is fired with the user accepts the input in the omnibox.
chrome.omnibox.onInputEntered.addListener(
function(text) {
if (text.indexOf("/") < 1) {
text += "/";
}
if (text.indexOf("http") < 0) {
text = "http://our-internal-portal/&quot; + text;
}
alert('We are taking you to: "' + text + '"');
navigate(text);
});
function navigate(url) {
chrome.tabs.getSelected(null, function(tab) {
chrome.tabs.update(tab.id, {url: url});
});
}

Here we will listen to the events of omnibox.onInputChanged and omnibox.onInputEntered in order to execute our logic.

Another point you might want to consider is to go to:

chrome://settings/ -> Advanced ->  and then to disable these options:

  • Use a web service to help resolve navigation errors
  • Use a prediction service to help complete searches and URLs typed in the address bar
  • Predict network actions to improve page load performance

It doesn’t matter if you are working in a startup of few people or a big organization with 2.2M employees (e.g. Walmart). In both cases, you probably have internal network and  internal systems that your users will love to access with few keywords like: CRM, ERP, Sale, Marketing, QA etc’.

Happy coding & Happy Passover.

Mobile Web Apps

mobile devicesLast week I had the pleasure to give this talk in Multi Screen-X event we had in Campus TLV. Mobile web apps are built using web technologies: HTML5, Javascript and CSS. The main advantage is that you write your application once (e.g. one source code) and deploy it on every platform: Android, Chromebook, Chromebox, Chrome and ya… even iPhone and iPad. Why it’s important today?
Well… as we know, the web is a huge platform and the one common application in any platform is the browser. One look at this set of devices (which is just the tip of the  iceberg) will tell the story:

On mobile devices the browsers’ current state, in terms of HTML5 support is (even) better then on desktops. You can see it per API in CanIUse.com or mobilehtml5.org Continue reading

Web Components Talk At HTML5-IL Meetup

Chrome love HTML5Last week I had the pleasure to take part in the first HTML5-IL meetup. If you are a front-end developer that live in Israel you should try and come to this group events. Lots of great developers, designers and others that share the same passion for the web. Great stuff. Unfortunately  I didn’t have more then 30min for this new, hot, complicated topic. So I hope to have more time to cover some of the aspects during the next meetup. From the four main aspects we touched only on the first two: Continue reading
