Talk: Cooking with NativeScript-Vue

Do you know Vue.js? Want to develop a native app? With NativeScript-Vue you can! In this talk, I will present the NativeScript-Vue ecosystem, and how developing production mobile apps feels like with this framework. You will discover what the main “haha!”s and “gotcha!”s are, specially if you come from a webdev background. In the end, you will know what NativeScript-Vue is in the real world, and if it is a good fit for your next native app development.

Sam Bellen

Developer Evangelist @ Auth0

I’m a Google Developer Expert who works as a Developer Evangelist at Auth0. At Auth0 we’re trying to make authentication and identification as easy as possible, while still keeping it secure.

After office hours I like to play around with the web-audio API, and other “exotic” browser API’s. One of my side projects is a library to add audio effects to an audio input using JavaScript.

When I’m not behind a computer, you can me find playing the guitar, having a beer at a concert, or trying to snap the next perfect picture.

Talk: Passwords are so 1990

As long as we’ve been using the internet, and way before that, we have been authenticating through some sort of username and password combination. It has become the standard. With the ever increasing number of web-apps, we’re seeing more and more data breaches as well. What if we could build our authentication processes in a way the user doesn’t need a password?

In this talk I will give a quick overview of the past, present and future of authentication. From basic authentication to passwordless biometric authentication using the web authentication API, and everything in between. The audience does not need any specific knowledge as this talk will not go into implementation details, but aims to give a view of what’s to come in terms of authentication.

Talk: Running in Parallel: WebAssembly, Web Workers and Worklets

UI is freezing, one of the CPU cores burning, you can do nothing at the moment. The only thing you can hear right now is the howl cooler. The single perception you can feel is hot as a hell metal case of the laptop. This is not a horror story or a thriller – this is a modern web app that runs everything in the main JS thread.

We should use the benefits of parallel computing to make the user feel like in a rainbow paradise instead of a nightmare. We have all the powers to execute the code in parallel and keep the main thread ready to interactions. With modern features like Web Workers, WebAssembly, and Worklets, this is not true anymore. I want to share the experience running jobs in parallel on real examples, that could be adapted to your requirements.

Talk: CSS GRID a most excellent adventure!

The CSS Grid specification is one of the most exciting additions to CSS, pretty much ever. And, much like Bill & Ted’s music did, it has the potential to create a “web” utopia in the future.

Kirsty will take you on a most excellent adventure exploring how to use CSS GRID in a production environment. Taking a tour of some of the new properties and units now available in the GRID Specification, how to create complex layouts and ensuring it is not a bogus journey by explaining some of the gotcha’s and how to get around them.

By the end, hopefully you will agree that CSS Grid really is Excellent!

Talk: React Rendering Strategies: Getting the most out of performance 🚀 while keeping bots happy 🤖

Rendering your app on the client is expensive. Quite expensive if you’re using a library such as React ⚛️. Applying a Server-Side Rendering strategy was the best solution to improve metrics like First Contentful Paint, and enhance the support for crawlers. Until now.

How can we improve the user experience in terms of performance while keeping the best support for crawlers? How can we mitigate the hydration cost? How to definitely improve our Time-To-Interactive metric of our React application? In this talk, we will share some of the techniques we have been using in Adevinta as well as our insights after applying them during months in production. We will explore what Dynamic Rendering and Progressive Rendering are, their benefits over the performance, the limitations of each one and how to implement them.

Talk: A modern approach to pagination

Vue and other modern frontend frameworks provide us developers with a lot of possibilities to deal with data and events. Yet working with data from APIs, especially paginated data, can be bothersome still. In this presentation, Max is going to talk about a more modern approach of dealing with paginated data from APIs that is leveraging Vue and Vuex.

Talk: Is AI Taking Over Frontend Testing?

Let’s face it: testing has issues, tests are flakey, selectors break, actions sometimes don’t happen and tests take a lot of time to write. Everyone should be doing them but in practice almost no one is satisfied with them.

Can we automatically generate all our end to end tests?

In this talk I’ll go over how I generated my frontend tests automatically without writing a single line of code and got good coverage. We’ll go over machine learning techniques applied to JavaScript.

He also likes using JavaScript to build stuff beyond the browser and finding out about unexpected uses for the web in general. He cares about community, diversity and inclusion as well. Making up silly personal needs in order to solve them with equally silly code projects is another of his questionable virtues.

Talk: You might not need classes

More than three years later, the introduction of classes to the ECMAScript standard is still a controversial topic. Brought over from popular classical object-oriented languages, they’ve not been argued an unnecessary feature for JavaScript, but their usage can become actually harmful very easily. In this talk we’ll take a look at the potential issues and pitfalls of using classes, like the need for context binding of methods, and suggest alternative patterns that are conceptually simpler, easier to work with, safer to use, more idiomatic, require less code and are actually more powerful. Come realize that all you really need in JavaScript are functions!

Talk: Components – More than a shinny Frenzy

More often than not developers fall into the trap of wanting to use some shinny trend heard in the IT world and that is no different with web components. Do you really understand the design decisions behind the concept of web components? In this talk, we’ll take a deep dive into what it is all about.

In the last few years, the term web components have become a main stay in frontend development and web development at large. This popularity as usual tends to come with a huge adoption in the industry albeit without people actually understanding the core concepts behind this new frenzy they’ve encountered. This isn’t limited to juniors alone. The goal of this talk is to give a deep dive into the background behind components, where it came from, how it has evolved and possibly what we might see in the future.

As a software engineer who volunteers as a teacher in a free self run coding school together with my peers, more often than not, a question we get from curious students and young developers are “why is this or that being used”. Giving answers like “it is used for this or that” has over the past year proved to be counter productive for trainees and engineers alike. With the last cohort of Code Afrique, we decided to take a different approach in explaining the concepts of web components by explaining the evolvement of web components from how Microsoft HTML Components and Mozilla XBL tried and failed and then Angular picked up by using the lessons learned from the failure to introduce what we now know as modern web components via a better semantic on web apps that allowed developers to create their own tags and how react further evolved it by fulfilling the need of reusable widgets. This we have seen has helped the developers and trainees have a better understanding of the concept of components on the web.

Talk: State management in a world of hooks

So you all in on hooks!! You’ve read all the articles, understand all the benefits, you’ve written some amazing custom hooks. But now – you can’t use them, because so much of the app is in global state management. So you naturally turn to the Context API, but is that enough?

In this talk, we will explore how we can leverage the power of hooks in global state management, what are the benefits and drawbacks to using Context API, and what alternatives do we have.

We will also discuss the steps to be taken to gradually introduce a new state management solution, and if that’s even possible.

Talk: The secrets behind Angular’s lightning speed

Angular developers rarely have the need to write super optimized code. In application development we tend to favor readability over optimization. But this approach doesn’t guarantee fast execution of the code. With frameworks, the situation is reversed. Frameworks have to be really fast. Interestingly, there are techniques that make JavaScript code run faster. You’ve probably heard about monomorphism, bit fields or bloom fliters, right? Maybe you’ve even used some of them. Over the past year I’ve seen them all and a bunch of other interesting techniques while reverse-engineering Angular. In this talk I want to share my findings with you. You may end up applying this knowledge at work or, who knows, may even use it to make Angular run even faster.

Talk: The curious case of a library maintainer

Vue.js might be a popular framework, but it wouldn’t become as good without the ecosystem of libraries around it. However, each case of a library is different. The idea, writing and decision making process, release schedule, documentation, testing, team and community management, support for SSR or Typescript, all of that is based on many factors. Let’s see what is similar about popular Vue libraries and what makes them unique. What caused particular projects to succeed, while others struggle to get traction. A talk not only for Vue developers.
