For close to 25 years now, JavaScript developers have suffered at the hands of time: the Date object. We have tried all sorts of solutions from using popular libraries like Moment.js all the way to handling dates and times on the backend.

Last year, I told you all about Temporal, a work-in-progress JavaScript proposal/initiative that I have been working on that aims to fix the situation by adding a date-time API to JavaScript that is truly futuristic.

Now it's time to show "time" who is boss. With the Temporal API stable at Stage 3 and the polyfill ready for production use, let me show you how to harness the power of this delightful API in order to build powerful JavaScript applications that handle dates and times like we always wished we could. We shall also discuss the orthogonal features being worked on in the JavaScript Intl API and find out how these play along with each other and come together to form a comprehensive set of APIs that allow us to build state of the art date and time components in our applications.

Web Components can feel like a bad fit for a JavaScript tech stack. If you’ve got a legacy codebase, you might be thinking about switching costs. Or you’re already running a modern stack and don’t see a need for them. But this shouldn’t be an either/or, you can have both!

Web Components work great as isolated improvements to your codebase. Their API is neat and tidy and doesn't require a "big switch". In this talk I'll give an overview of Web Components and explore examples of how you can use Web Components practically in any codebase.

What do we really mean when we talk about “ethics” in tech? What are we actually aiming for, and what specifically can we all do to get there? It’s not enough to point out existing issues with racist, sexist tech, products that are easily weaponized for abuse, or harmful tech workplaces - we need intentional strategies for creating a tech industry that is truly ethical.

This talk breaks down the call for “ethical tech” into the need for both our tech industry and the products we create to be focused on safety, justice, and compassion. This talk focuses on how we can transform tech in terms of the industry and the products it makes to prioritize those things, drawing on historical case studies of other movements that shifted paradigms from unethical to ethical.

Developers will learn

• What does the 'install capability' unlock for users
• What use cases are typically suitable for installed web apps, why & how not to annoy users by forcing them to install
• When to ask the user to install for common use cases (and when not to!)
• What patterns to use to promote installable web apps without being annoying
• How to trigger the install prompt and measure interactions

In 2020 PWAs turned 5. So in that milestone year, what's the reality of PWA developer adoption? Hemanth HM, author of the chapter on PWAs in the most recent Web Almanac, a comprehensive report on the state of the web, backed by real data from HTTP archive, and trusted web experts, dives into real world adoption of the technologies underpinning PWAs, to see just how in reality PWAs are being deployed.

Neural Networks are an approach to machine learning (specifically Deep Learning) that are now widely used from supercomputers to your smartphone (via APIs like CireML in iOS and Neural Networks API on Android). The Web Neural Network API (WebNN) in development at the W3C aims to bring Neural Networks natively to the browser, and with them solutions to a range of common use cases including Face Recognition, Facial Feature Detection, image captioning, and much more. And best of all you can start exploring it today with the WebNN polyfill.

In this presentation Ningxin Hu, one of the editors of the WebNN specification, takes us through its features and aims, and how we can get started using WebNN right now.

The file input element and the download attribute on anchor elements used to be the primary way for working with files on the Web. Not anymore! In this presentation, I will show modern ways of dealing with files in the browser and how they integrate with the clipboard, drag and drop, and your operating system's file explorer. You will also learn that not all files are created equal! This will be a pre-recorded "live"-coding session, so expect no slides, no coding glitches; just pure edutainment!
