File this under "better late than never". Before the year closes out, I wanted to post my 2015 DrupalCon Barcelona keynote video and slides. I archive all my DrupalCon keynotes on my site so anyone who is interested in taking a trip to memory lane or studying the evolution of Drupal, can check out all my previous DrupalCon keynotes.
My DrupalCon Barcelona keynote is focused on having a realistic, open and honest conversation about the state of Drupal. In it, I broke down my thoughts on Drupal's market position, development process, and "decoupled Drupal". You can watch the recording of my keynote or download a copy of my slides (PDF, 27 MB).
As user experiences evolve from static pages to application-like experiences, end users' expectations of websites have become increasingly demanding. The Facebook newsfeed, the Gmail inbox, and the Twitter live stream are all compelling examples that form a baseline for the application-like experiences users now take for granted.
Many of Drupal's administrative interfaces and Drupal sites could benefit from a similarly seamless, instantaneous user experience. Drupal's user interfaces for content modeling (Field UI), layout management (Panels), and block management would benefit from no page refreshes, instant previews, and interface previews. These traits could also enrich the experience of site visitors; Drupal's commenting functionality could similarly gain from these characteristics and resemble an experience more like the commenting experience found in Facebook.
As Drupal's project lead, I ask myself: how can our community feel enabled and encouraged to start building rich user experiences?
In recent years, the emergence of decoupled architectures with client-side frameworks and libraries have helped our industry build these experiences. Does that mean we have to decouple Drupal's front-facing site experience (for site visitors or end users) and/or the administration experience (for content editors and site builders)? If so, should Drupal decouple the administration layer differently from the front-facing site experience? By extension, should a client-side framework guide this change?
Here is my current thinking: in the short term, Drupal should work toward a next-generation user experience under progressive decoupling for both the administration layer and the end user experience. At the same time, we should enable fully decoupled end-user and administrative experiences to be built on Drupal too. In my view, the best way to achieve this is to formally standardize on a full-featured MV* framework (e.g. Angular, Ember, Backbone, and Knockout) or a component-based view library (e.g. React, Vue, and Riot). In this blog post, I want to kick off the discussion and walk you through my current position in some more detail.
Should we decouple Drupal itself?
There is no doubt that Drupal's administration layer is very application-like and would benefit from an experience that is more interactive. For the end-user experience, a decoupled implementation is not always the best option. Some sites may not need or want the application-like interactivity that a client-side framework would provide, since not every site needs interaction. For instance, news sites or blogs do not need much interactivity, custom applications need a great deal, while e-commerce sites lie somewhere in the middle. It's not clear-cut, so let's look at our options in more detail.
|Approach||User experience||Developer experience||Ease of implementation|
No immediate feedback
Theme layer preserved
Modules in mostly PHP
Ad-hoc client-side code
No server-side change

How should Drupal decouple its user experience?
Drupal's administration layer (content editor and site builder experience) is effectively an application. Fully decoupling may be the appropriate call to achieve the best possible user experience for creating, managing and presenting content. However, rewriting the administration layer from the ground up is a monumental task, especially since its modules provide powerful interfaces that allow site builders to build robust, complex sites without a line of code.
The same expectations for application-like interactivity often hold for the end-user experience: users expect shopping carts, comments, notifications, and searches to be updated instantaneously, without having to wait for a page to load.
For both the administration layer and the end-user experience, I believe the Drupal front end should not be fully decoupled out of the box. We should advance from our traditional paradigm and default to progressive decoupling. It allows us to achieve the user experience we want without significant downsides, since not every use case would benefit from fully decoupling. Through progressive decoupling, Drupal could potentially reach the ideals of the assembled web more quickly by preserving a tight link between Drupal modules and their front-end components.
Nonetheless, we should empower people building fully decoupled sites and applications. Depending on the use case, Drupal 8 is a good match for decoupled applications but we should improve and extend Drupal's REST API, enhance contributed modules such as Services, and shore up new features such as GraphQL (demo video) so more functionality can be decoupled. Front-end developers can then use any framework of their choice — whether it is Angular, Ember, React, or something else — to build a fully decoupled administrative application.
Should Drupal standardize on a single framework?
All things considered, I do believe Drupal should standardize on a single client-side framework, but it should only make such an explicit recommendation for progressively decoupled Drupal, not fully decoupled architectures. It would result in a more seamless user experience, better compatibility across interactive components in modules, maximum code reuse, a more consistent front-end developer experience, more maintainable code, and better performance as we don't have to load multiple frameworks.
Despite the potential benefits, there are also good reasons not to embrace a single client-side framework. New front-end frameworks are being created at what feels like an unsustainable pace; every nine months there is a new kid on the block. It's hard for a project as large as Drupal to embrace a single technology when there is no guarantee of its longevity.
For instance, Backbone, with its underlying library Underscore, currently powers interactions in the toolbar and in-place editing in Drupal 8. Though Drupal could expand the scope of Backbone in core and encourage front-end developers to build with it, it means buying even further into a framework that is quite old among its peers.
To deal with the fast-evolving nature of the front-end landscape, we need to be thoughtful about which framework we choose, to reassess our choice from time to time, and to make sure we can migrate fairly easily if we so decide.
What client-side framework should Drupal standardize on?
Assuming we agree that embracing a single client-side framework makes sense for Drupal, there are actually three additional questions: what framework to standardize on, how to do it, and when to decide.
I'm the first to admit I'm not the best person to answer the first question. As I'm not a front-end developer, I'm looking at you, the Drupal community, to help answer this question. I'd hope that the chosen framework aligns well with both our architecture (modular, flexible) and community (collaborative, community-driven).
The second question — how to standardize on a framework — I can help answer. On the one extreme, Drupal could be opinionated and ship a client-side framework with Drupal core, meaning that every installation of Drupal ships with the chosen framework. This would be much like the adoptions of jQuery and Backbone.js. On the other end of the spectrum, Drupal could recommend a specific framework but not ship with it. Finally, somewhere in between, Drupal could provide a default standard framework in core but make it easy to replace with it a framework of a developer's choice, though the likelihood of this is quite small. This is akin to Drupal core shipping with a template engine (i.e. PHPTemplate) that could be (but was rarely) replaced with another. Ultimately, I think we get the best result if Drupal ships with a specific framework—much like the adoption of jQuery in Drupal 5.
The last question, when to standardize on a framework, is important too. I would recommend we experiment with possible directions as soon as possible in order to decide on a final vision sooner rather than later.
I believe that, for now, it makes more sense to progressively decouple Drupal sites and their administration layer by first building our pages with Drupal. Once the page is loaded, we can let a unified client-side framework take over as much of the page as needed to foster a next-generation user experience without reinventing the wheel or alienating developers.
That is not all! We will need module developers to bring rich interactions to their user interfaces with the help of the framework we choose. We will need designers to guide module developers in building a graceful user interface. We will need front-end developers to demonstrate how they want to develop the user experiences that will define Drupal for years to come. We will need users to test and validate all of our work. It will be tough going, but together, we can ensure Drupal stays ahead of the curve well into the future.
One thing that is exciting to me, is how much we appear to have gotten right in Drupal 8. The other day, for example, I stumbled upon a recent article from the LinkedIn engineering team describing how they completely changed how their homepage is built. Their primary engineering objective was to deliver the fastest page load time possible, and one of the crucial ingredients to achieve that was Facebook's BigPipe.
When a very high-profile, very high-traffic, highly personalized site like LinkedIn uses the same technique as Drupal 8, that solidifies my belief in Drupal 8.
LinkedIn supports both server-side and client-side rendering. While Drupal 8 does server-side rendering, we're still missing explicit support for client-side rendering. The advantage of client-side rendering versus server-side rendering is debatable. I've touched upon it in my blog post on progressive decoupling, but I'll address the topic of client-side rendering in a future blog post.
However, there is also something LinkedIn could learn from Drupal! Every component of a LinkedIn page that should be delivered via BigPipe needs to write BigPipe-specific code which is prone to errors and requires all engineers to be familiar with BigPipe. Drupal 8 on the other hand has a level of abstraction that allows BigPipe to work without the need for BigPipe-specific code. Thanks to Drupal's higher-level API, Drupal module developers don't have to understand BigPipe: Drupal 8 knows what page components are poorly cacheable or not cacheable at all, and what page components are renderable in isolation, and uses that information to automatically optimize the delivery of page components using BigPipe.
It is exciting to see Drupal support the advanced techniques that were previously only within reach of the top 50 most visited sites of the world! Drupal's BigPipe support will benefit websites small and large.
Building Drupal 8 with all of you has been a wild ride. I thought it would be fun to take a little end-of-week look back at some of our community's biggest milestones through Twitter. If you can think of others important Tweets, please share them in the comments, and I'll update the post.
Feeling nostalgic? See every single version of Drupal running!

We just released Drupal 8.0.0! Today really marks the beginning of a new era for Drupal. Over the course of almost five years, we've brought the work of more than 3,000 contributors together to make something that is more flexible, more innovative, more easy to use, and more scalable.
Drupal 8 has been a big transformation for our community. This particular reboot has taken one-third of Drupal's lifespan to complete. In the process we've learned that reinvention doesn't come easily or quickly. There are huge market forces happening around us, and we can't exactly look away. Mobile is moving our society to near-universal, global internet access. Most companies have begun to transform themselves digitally, leaving established business models and old business processes in the dust. Digital experience builders are turning to platforms that give them greater flexibility, better usability, better integrations, and faster innovation. The pace of change in the digital world has become dizzying. If we were to ignore these market forces, Drupal would be caught flat-footed and quickly become irrelevant.
But we didn't. I'm proud to see that we've responded to these market forces with Drupal 8, and delivered a robust, solid product that can be used to build next-generation websites, web applications and digital experiences. We've implemented a more modern development framework, reimagined the usability and authoring experience, and made technical improvements that will help us build for the multilingual, mobile and highly personalized experiences of the future. From how we model content and get content in and out the system, to how we build and assemble experiences on various devices, to how we scale that to millions and millions of pageviews -- it all got much better with Drupal 8.
I'm personally incredibly proud of this release. Drupal 8 is the result of years of hard work and innovation by thousands of people, with lots of attention to detail at every level. Congratulations to everyone who stepped up to contribute; this was only possible thanks to your persistence and tireless hard work. It took a lot of learning, our best thinking and our best people to create Drupal 8, and I'm very, very proud of what we have accomplished together.
For 15 years, I have believed that Open Source offers significant advantages to proprietary solutions through superior innovation. Today, I believe that more than ever. Drupal 8 is another key milestone in helping us win and doing what is best for an open web. Of course, our job is not done but now is the time to have fun and celebrate this monumental milestone. Tonight, we'll be hosting more than 200 parties around the world! (It's also my 37th birthday today and the release of Drupal 8 along with all those parties is pretty much the best present ever!)
