A conference all about front end performance

About lazy load

Front end performance used to be a relatively simple task–minifying, concatenating and gzipping, a bit of smushing images, and all done.

But in 2022 it's far more than that, and only getting more complex. That's where lazy load comes in. A conference dedicated to front end performance, we'll cover what you need to know now, and what's coming next.

Who's it for?

If you build front ends, lazy load is for you.

In depth knowledge

All Web Directions conferences feature in-depth knowledge from real world experts. Some you'll know, many you won't, but all bring a world of experience and knowledge.

Optimising for Core Web Vitals on SPAs

Core Web Vitals have been a great catalyst to get SEO, marketing, business and technical teams together to work on web performance. It has raised a lot of questions though, especially about how these new performance metrics are measured, what impact they have on SEO and how best to optimise them.

Join me as I walk through the key concepts of Core Web Vitals, from a brief introduction to the metrics through to how they are calculated in the browser and the impact they have on SEO. Critically, we will review how these metrics work on single page applications — it’s not quite as clear or simple as you might expect!

I will share practical tips, clear any confusion and empower you to be the go-to expert on Core Web Vitals in your organisation. We will look at practical examples including how some simple optimisations have helped a client move from a mix of red and yellow results to a sea of green.

A New Measure of Responsiveness

Page load time is an important aspect of performance, but it's not the only one. After a site has loaded, it should respond quickly to clicks, taps, and keypresses. But this can be difficult to measure and optimize.

I'll talk about the Event Timing API and how it can be used to measure interaction timings in RUM analytics and lab tooling. Then I'll dig deeper into understanding where the time is going, breaking down the problems that end users are seeing and reproducing them in the lab.

Finally I'll talk about some common problems my team and I have seen as we've dug into how responsive web sites are to user interactions, and how to avoid them.

Get speedy with responsive images automation

Responsive images done right can lower your website LCP and be a money saver. But do them right can be complex and require lots of math and considerations.

In the latest years I spent a lot of my time as performance architect helping e-commerce teams getting them right, and I’ve finally managed to automate all the optimisation process, in a customer-driven way.

In this talk I’ll explain best practices, bring data, and show you how my open-source automated tool works for you to use it.

Optimising Web Fonts to enhance Web Performance

Web fonts contribute to the aesthetics and experience of a website or a web application which in turn enhances the user experience and communicate the voice and tone of a brand but it can can also have an impact on page size which can slow down load time and speed of a web application if not properly rendered.

I aim to address how web fonts can be rendered and used on web applications without affecting page size and load times of the said web application.

Performance Mistakes–an HTTP Archive deep dive

Web performance is a complicated topic, but over the years it’s become easier to articulate thanks to incredible advancements in performance features, their adoption in the browser ecosystem and tools that test and give insight into which techniques might speed up your site.

However, all too often a feature is implemented incorrectly, resulting in a lost opportunity for performance improvement. During this talk I’d like to explore a few common web performance techniques - some that you are likely already familiar with. We’ll dive into HTTP Archive data to find some examples of sites that are using them incorrectly, and explore the impact and potential benefits of fixing them.

An Opinionated Guide to Performance Budgets

A performance budget is a threshold that you apply to the metrics you care about the most. Budgets are the best way to get fast and fight regression. But they’re one of those ideas that everyone gets behind conceptually, only to find them tricky to put into practice – and for very good reason. Web pages are unbelievably complex, and there are hundreds of potential performance metrics to track.

If you’re just getting started with performance budgets – or if you’ve been using them for a while and want to validate your work – this talk is for you.

Tammy will cover:

• Which metrics to focus on • What your budget thresholds should be • How to stay on top of your budgets

Designing distributed applications

In this talk Andrew will present a number of new concepts for building decentralised apps and help to show that maybe, there’s a solution that would suit you. Modern web apps increasingly share a common set of best practices. In 2012, one of Heroku’s founders published "The 12-factor app", a thesis on application design that describes pretty well how most scalable applications are built today.

But much has also changed – with a wealth of powerful ‘serverless’ technologies to choose from, application design has evolved. Now, the ‘edge cloud’ is starting to become a mainstream idea, with even small organisations able to harness the power of executing complex applications simultaneously in hundreds of different datacenters to minimise end user latency. Even for things we thought we had to run centrally.

This talk will review the most popular architectural principles of web applications today, and examine how suitable they are for operating an app at the edge.

Executing at the edge is not only very cool and the Latest Thing, it is also a boon to efficiency, is environmentally aware, and a great way to increase the reliability and availability of applications too.

Shipping features without deploying them

The status quo for web service providers is to provide a wide range of products that suit the needs of every customer and industry. With the advent of edge computing, we have begun to transform the way we expose functionality to customers by shipping installable libraries that can be used on our programmable edge platform, allowing us to release quickly and often.

Re-imagined as remote-only

In response to the unique challenges of COVID-19 we transformed our conferences into remote only events. But we wanted to go way beyond what most online events delvier.

Building on the extensive work we've done with our conference presentation platform Conffab, our conferences have been re-imagined from the ground up the conference experience, not just ports of traditional conferences to the Web.

With a focus on highly engaging, expertly filmed and edited, screen-oriented presentations, alongside spaces to connect, communicate and keep in touch with everything around the conference, you'll be immersed as if you were there–maybe even more so.

How will lazy load be held?

Most online conferences run just like in-person conferences–one or two jam-packed days, of live streamed presentation. But with so many folks working remotely, and spending so much of their day in front of a screen we felt it was imperative to rethink this, and do something differently.

Hosted on our own purpose built platform, like all our online events, Lazy Load takes place over 2 consecutive Fridays, in June 2022. Each sessions runs around 4 hours (with a bit of downtime built-in), Plus each session runs 3 times so wherever you are in the world, you can participate along with your peers, from the comfort of your own home (or maybe office).


We work closely with our partners and their technologies to deliver world leading online conferences.
