Many of us care deeply about developing our craft. But staying up to date can be a true challenge, because the quantity of fresh information we’re regularly exposed to can be a lot to take in. 2012 has been no exception, with a wealth of evolution and refinement going on in the front end.
Great strides have been made in how we approach workflow, use abstractions, appreciate code quality and tackle the measurement and betterment of performance. If you’ve been busy and haven’t had time to catch up on the latest developments in these areas, don’t worry.
With the holiday season upon us and a little more time on our hands, I thought it would be useful to share a carefully curated list of the most relevant front-end talks I’ve found helpful this year. You certainly don’t have to read through them all, but the advice shared in them will equip you with the knowledge needed to go into the new year as a better front-end engineer.
Have a Strategy for Staying Up to Date
Part of continually developing your craft is staying up to date. Doing this is important for all professionals, and in this talk you’ll learn strategies for staying updated even when the ideas that surround the technologies we use are constantly evolving.
Make Sure Your Baseline for Development Is Current
This has greatly changed over the past few years, with improvements in workflow and tooling. Front-end development is now taken more seriously, and this talk sheds light on the new baseline process for developing on the front end.
Understand How Browsers Work Behind the Scenes
Some would say that the browser is the most volatile development platform the world has ever known. If you’re a client-side developer, understanding how browser internals work can help you both make better decisions and appreciate the justifications behind many development best practices. In one of the best talks this year, David Mosher takes you through how browsers parse and render your pages.
Know What the Web Platform Now Has to Offer
The Web is constantly evolving, and keeping up with what’s new on the platform can be hard. HTML5’s new capabilities enable us to build an entirely new suite of applications with features that were simply impossible to achieve before (at least, not without the use of plugins) but are now a reality.
In this talk, my teammate Eric guides you through the bleeding edge of HTML5, focusing on solving many real-world problems. You’ll learn about media streaming, device input, modern CSS design, media capture, file I/O and more.
For Web App Developers
In this talk, you’ll get an overview of the current tooling eco-system for the front-end and learn about a new tool that tries to bring together all of the pieces of this eco-system for you, called Yeoman12.
For Web Designers
A lot is expected from today’s Web designers. If this role defines what you do, then it’s now not just about visual design, but increasingly about building interactions. Designs need to work across different devices of varying shapes, sizes and connections, and they also need to be accessible.
As a designer, you often need to communicate and share code across teams and be familiar with many different technologies. In this talk, Chris Coyier discusses many of the amazing tools that can help things along, discussing what does what and giving a high-level view of a modern workflow.
For Mobile Web Developers
Building for the mobile Web requires a different mindset to the one we use when developing for desktop, and a different set of tools. Thankfully, a number of great options are available. From remote debugging to emulation, mobile browsers are offering more and more tools to make our lives easier.
In this talk, Pete Le Page takes you through a couple of tools that you can use today to make cross-platform mobile Web development easier, and then he peers into the crystal ball to see what tools the future may bring.
Google Chrome Developer Tools provide powerful ways to understand, debug and profile Web applications. Most developers are familiar with Chrome’s basic inspection and debugging tools, but some of its most valuable features, like the Timeline23 and memory analysis tools, are less known.
In his demo-based walkthrough, Patrick Dubroy provides an overview of Chrome Developer Tools and an in-depth demonstration of some lesser-known features.
In this talk, Peter looks briefly at the state of CSS3: what you can do right now, and what you’ll be able to do in the very near future. He then looks into the long-term future, to a time when CSS3 will make possible page layouts far richer and more dynamic than we’d thought possible, and when CSS3 has taken on aspects of programming languages. This is effectively what CSS developers will be learning years from now.
Web Components and the Future of Web App Development30, Eric Bidelman
Web components are going to fundamentally change the way we think, build and consume Web apps. ShadowDOM31, Mutation Observers32, custom elements, MDV33, Object.observe()34, CSS — how do they all fit together?
This talk prepares you for the future of the Web platform by discussing the fundamentals of Web components and how we can use them today with frameworks such as AngularJS.
State of the Art
This talk dives into some of the latest CSS implementations and specifications floating around. You’ll learn what’s here and what’s around the corner, and you’ll gain insight into why these new features will change our development workflow.
We all think that CSS is easy. Take some selectors, add some properties, maybe a dash of media queries, and — presto! — you have a beautiful website. And yet, as the project changes and the team grows, we see the frustration build, with increasingly complex selectors and overuse of
In this talk, Jonathan looks at common problems and solutions that will make your CSS (and your projects) easier to manage and easier to scale.
If you haven’t jumped on the pre-processor train this year, you’re missing out. In this helpful overview of (current) popular pre-processors, Bermon Painter takes you through Stylus, LESS and Sass, with features subdivided into easy-to-learn sections of beginner, intermediate and advanced. I’ve been using mixins quite heavily this year, and I simply wouldn’t have been able to if it weren’t for projects like Sass.
Writing maintainable CSS within a team is one of those problems that a lot of people think can be solved by writing CSS in a particular style. But in Kyle’s experience, that never works out.
In this talk, he introduces you to his latest creation, KSS50. It’s a documentation and style guide format. He’ll show you why he built KSS and how it’s been helping him at GitHub to refactor its four-and-a-half year old CSS, and he’ll give you a glimpse into the future of KSS.
The Importance of Code Style
Some say that good code is its own documentation, and the fact is that the more readable our code is, the easier it is to maintain.
A Modern Large-Scale App Stack
I’ve talked a lot about large-scale development55 in the past. It’s a non-trivial problem that’s difficult to get right, and so it’s exciting when someone working on such challenges shares their experience.
Rethinking Application Structure
In this talk, you’ll get a tour of how to get the power of tomorrow’s Web platform in today’s Web applications.
Internationalization and i18n
In this talk, Sebastian takes you through how to spot real-world internationalization problems and how to solve them in the most elegant way.
I couldn’t cover internationalization without mentioning Alex Sexton, who has also spoken a great deal on this topic. His JSConf talk on client-side internationalization is available in video65 form if you’re interested in checking it out.
Patterns and Principles
When to Lazy Load Scripts
Reducing the loading time of a Web application is a well-known challenge. Developers need to make sure that the browser downloads only the code that is strictly necessary to bootstrap the application, and leave the rest for later. This is what we commonly call “lazy loading.”
Building Touch-Based Interfaces
Flickr front-end engineer Stephen Woods shares some hard-learned lessons about building responsive touch-based interfaces using HTML5 and CSS. Because our users are demanding better instant feedback from touch-based UIs, understanding how to approach this problem and avoid the pitfalls will be critical for many application developers in the future.
The Challenge With Scrolling
Scrolling effects are a popular way to add personality to the simple act of moving down the page. Unfortunately, these effects don’t work natively on mobile devices, where the touch interaction would make these techniques more effective. In this talk, Mark looks at some ways to implement these effects within the limitations of mobile browsers.
Native, HTML5 and Hybrid Apps
One of the toughest decisions every mobile developer faces is choosing a development strategy: “Should I develop a native, HTML5 or hybrid mobile app?” Over the past two years, Eran has led Conduit’s mobile client development efforts, experimenting with cross-platform development in various flavors: from complete HTML5 solutions (using PhoneGap and other technologies) to hybrid solutions to semi-hybrid solutions to fully native solutions.
In this talk, Eran shares some real-life experiences in cross-platform development, describing changes that Conduit has implemented along the way, and sharing what some of the “big players” (such as Facebook, LinkedIn and Twitter) are doing in their mobile app development.
Performance, Distribution and Facebook on HTML5
Simon looks at Facebook’s experience with and investment in the mobile Web, the issues affecting mobile Web developers and what Facebook and the industry are doing to push the mobile Web forward. Mark Zuckerberg’s comments on HTML5 were undoubtedly one of the most discussed topics in mobile this year, and I personally found these slides a good summary of Facebook’s current take on what works and what still requires improvement.
Tools for Mobile Debugging
Debugging Web apps on mobile devices can be a genuine pain. Luckily, a number of tools are available today to ease the process. From remote debuggers to cross-device consoles, this talk summarizes the current state of debugging for mobile, going into more depth on debugging than Pete’s talk from earlier in the post.
Responsive Design Techniques
Responsive Web design challenges designers to apply a new mindset to their design processes and to the techniques they use in design and coding. This talk (by Smashing Magazine’s own Vitaly Friedman) provides an overview of various practical techniques, tips and tricks that you might want to be aware of when working on a new responsive design project.
Offline Web Apps
In the last couple of years, a deluge of new offline storage technologies have appeared. In this talk, Andrew looks at why they are all excellent and rubbish at the same time and why you need to use all of them, and he walks through techniques to consider when building a Web application that can load and function with no network connectivity.
But making use of client-side storage is necessary not only in order to make an app that works offline, but it can also hugely improve the experience of your website when the user actually does have connectivity.
State of the Art
The browser is an amazing runtime that can already deliver amazing apps. Paul dives into the technologies that will help you deliver Web apps that will blow your users’ socks off now and in the future.
Installed native applications can use all the space they want, but in the browser we’re much more limited. This talk explores how to make the best use of the storage technologies available to Web apps, comparing the virtues of different packaging and encoding techniques, and covering simple forms of in-browser compression that can yield surprising results.
As more apps are developed to surf over network turbulence, and to work even when completely disconnected from the network, local storage becomes ever more important.
The Application Cache is one of the cool bits of HTML5. It allows websites to work without a network connection, and it brings us much closer to native app-like behavior. However, from roundup articles and talks about HTML5, you might be left with the impression that it’s a magic bullet. Unfortunately, it isn’t; the Application Cache is, as Jake famously puts it, a douchebag.
In this talk, he looks at how to use the features of Application Cache without the horrible side effects, comparing techniques that you’d use for both a simple client-side app and a large content-driven website. He explores the many gotchas left out of most articles about Application Cache and discusses how to build your website to survive them.
Paul dives into the tools available in and outside of the browser to assess the performance of your CSS. Find out what’s slow (is
box-shadow causing paints to be 70 milliseconds longer?) and how to fix it. Learn about
about:tracing, CSS profiling and speed tracer, and get a better understanding of the browser’s internals in the process.
There’s also Jon Rohan’s talk about some problems related to CSS performance that were solved at GitHub. Recommended reading.
Building beautiful experiences on the mobile Web takes more than a good designer and fancy CSS: performance is critical for a Web app to feel fluid. Smooth animation that never drops a frame can give your app a native feel. But when animations stutter, effects lag or pages scroll slowly, we call that “jank.” This talk is about identifying jank and getting rid of it.
In this comprehensive crash course, Ilya Grigorik shares some really juicy tips on how to make the Web faster, including Google’s findings on what slows down people’s Web experience and how Chrome and other services have improved it. If you’re an engineer looking to improve the performance of your websites or apps, this talk comes highly recommended.
Understanding Code Smells
Odors exist for a reason, and they are usually trying to tell us something. If our code smells, it might be trying to tell us what is wrong.
Does a test case require an abundance of setting up? Maybe the code being tested is doing too much, or it is not isolated enough for the test? Does an object have an abundance of instance variables? Maybe it should be split into multiple objects? Is a view brittle? Maybe it is too tightly coupled to a model, or maybe the logic needs to be abstracted into an object that can be tested?
In this talk, Brandon walks through code from projects that he works on every day, looking for smells that indicate problems, understanding why the smells are there, what the smells are trying to tell us, and how to refactor them.
Current State of the Art
A myriad of testing tools and solutions are available, and Adam shows what’s out there and what we as a community need to do next to get the Holy Grail, to ensure a better Web experience for everyone.
Improving the Testability of Your Code
It’s one thing to write the code that you need to write to get something working; quite another to write the code that you need to write to prove that it works — and to prove that it will continue to work as you refactor and add new features.
Time spent thinking about (and developing) your craft is time well spent. The more honed your skills are, the more opportunity you will have to become an efficient engineer.
While this list doesn’t cover every excellent talk presented this year, it hopefully offers some direction for you to accentuate your skills. Do consider reading through a few of them. Focused reading in this way will add to your value as a craftsperson and hopefully improve your daily development workflow.
With that, do enjoy the holiday season and have a fantastic new year.
