Thoughts on Blink
Keep in mind that there are many different players in the Webkit space. As with any massive open source project each player is somewhat limited in what they may do to the code before they have a negative effect on someone else.
Basically Google is saying that the cost of supporting all the code is outweighing the benefits. They are betting that they can innovate quicker on their own code base.
In the announcment they even highlight
For example, we anticipate that we’ll be able to remove 7 build systems and delete more than 7,000 files—comprising more than 4.5 million lines
Haters gonna hate?
At the time there were howls of lament on Hacker News and across Twitter from people who were convinced that this was the end of the web as we knew it.
Webkit had become the new IE and innovation would now grind to a halt. We might as well get out our fucking blink tags and table based layouts.
I never believed that argument FWIW. IE6 was always about lowest common denominator. No matter what great features came to us from the Gods at the W3C we couldn't use them without some god awful polyfill hack.
Webkit on the other hand seems to be a form of highest common denominator. All
the browsers that are part of the ecosystem get a standard and common set of
functionality out of the box. They then build their own custom stuff on top of
it which is hidden behind a vendor prefix like
No more prefixes :-[
One part that really stood out to me as a negative was the vendor prefixes section on the Blink page.
They mention that they'll no longer support experimental features with vendor
prefixes. Instead they'll have the unprefixed feature hidden behind a flag which
can be turned on in
I think this totally sucks. Let's be completely honest. We've all been building sites with vendor prefixes for years. We've been using drop shadows and rounded corners with vendor prefixes long before they were 'officially' supported.
We were well aware that our rounded corners would gracefully degrade to non-rounded corners for users running older browsers but it was something that we were willing to live with to get the benefit of pushing the vendor prefixed code out to the millions of users running modern browsers.
With this new decision to hide all experimental features behind a flag we're removing the developer's power to build an app with any api that they choose.
Opera, Apple, and the rest
You've gotta wonder what the people at Opera are thinking right now. After going all in on Webkit only two months ago they find out today that Google is coming out with something even better.
I'm unclear on exactly how much code Google contributes to Webkit on the regular but this could potentially slow down the pace of innovation in the Webkit code base considerably.
Of course it could have the opposite effect as well. Just as Google is able to remove 4.5 million lines perhaps a similar amount can be removed on the Webkit side which would have huge benefit for size is no virtue in software.
But no matter what's to be gained from removing Google specific code from the codebase it won't come close to balancing what'll be lost by having no more Google contributions to the codebase. There's no other way to spin this—it's a bad thing for the Webkit community and codebase.
Of course Apple is heavily invested in Webkit and will presumably keep supporting it and improving it.
It's amazing that the Google team were able to keep their mouths shut at the time when everyone was talking so much crap about the Webkit monoculture. Here they were about to fork the entire project and they had to keep hush hush.
My personal opinion is that this is a good thing. I often think of codebases as living breathing organisms which grow and evolve over time. You can clearly draw lineages in codebases which live many years and go through multiple refactorings.
In this case this is like some type of evolutionary split. From here on out Blink is a completely new organism. Both it and Webkit will begin to evolve down their own paths. In a couple of years it will be interesting to compare them both to see where exactly they've grown apart and in what ways.
As jQuery creator John Resig said on twitter earlier:
Moz + Samsung are working on Servo, Google forked WebKit, and Opera is switching to Chromium -- we're entering a new age of browserdom!
