Opensource Documentation—Tales from React and React Native
Documentation is often your community's first point of contact with your project and their daily companion at work. So why is documentation the last thing that gets done, and how can we do it better? This talk shares how important documentation is for React and React Native and how you can invest in or contribute to making your favourite project's docs to build a thriving community
The Eternal Sunshine of the Zero Build Pipeline

The Eternal Sunshine of the Zero Build Pipeline
For many years, we have migrated all our devtools to Node.js for the sake of simplicity: a common language (JS/TS), a large ecosystem (NPM), and a powerful engine. In the meantime, we moved a lot of computation tasks to the client-side thanks to PWA and JavaScript Hegemony.
So we made Webapps for years, developing with awesome reactive frameworks and bundling a lot of dependencies. We progressively moved from our simplicity to complex apps toolchains. We've become the new Java-like ecosystem. It sucks.
It's 2021, we've got a lot of new technologies to sustain our Users eXperience. It's time to have a break and rethink our tools rather than going faster and faster in the same direction. It's time to redesign the Developer eXperience. It's time for a bundle-free dev environment. It's time to embrace a new frontend building philosophy, still with our lovely JavaScript.
Introducing Snowpack, Vite, Astro, and other Bare Modules tools concepts!
The State of XState
18 min
The State of XState
Over the past few years, state machines, statecharts, and the actor model have proven to be viable concepts for building complex application logic in a clear, visual way with XState. In this talk, we'll take a peek into the future of XState, including new features in the next version, and new tools and services that will make it even easier to create and collaborate on state machines.

Hooks are a great abstraction model
13 min
Hooks are a great abstraction model
The discussion explores the separation of concerns between logic (Model) and UI (View) and how React hooks are a great abstraction model that help achieve that.
We'll start with designing a component's API (in a top down approach), then dive deeper to explore how to implement this API, while maintaining a good separation of concerns.
We'll create custom React hooks to implement the Model and React components for the UI. Both expose self-documenting APIs and are completely decoupled from each other.
To demo this approach, we'll create a simple Toggler component (a UI component that allows going back and forth in an array of values).Towards the end, we'll explore the benefits, focusing on testing these decoupled units in isolation.

The Actor Model: a new mental model for React
37 min
The Actor Model: a new mental model for React
System-level state management in modern React applications is challenging. Usually, as the applications grow, the complexity of interaction between different parts of the application compounds. The more you need those isolated parts to talk, the higher the level of complexity. Usually, the common pitfalls of these communications are underestimated especially with the recent trend of State management that tends to keep the application state outside of React and distributed. In this talk, We'll see how the Actor Model architecture can come to the rescue and what makes it stand out compared to the other approaches.

React Bricks: a CMS with visual editing based on React components
Headless CMSs are great for developers, but not for content creators.
React Bricks is the first CMS that is super-great for Developers (it's just React, backed solid APIs), for Content Creators (it keeps the visual editing experience of no-code tools like Wix) and for Designers (you can express your exact design system and be sure nobody will break it). I'll show you how it works!

Introducing state machines and statecharts
State machines and statecharts can seem intimidating. Especially if you (like me!) didn’t study computer science, aren’t big into maths, or just haven’t come across state machines and statecharts before.
In this session, you’ll get a whirlwind introduction to state machines and statecharts, no prior knowledge and no coding experience required. Are you already familiar with state machines and statecharts but want to get a better understanding of the benefits and how to convince your team to get onboard? That’ll be covered too.
You could be a developer, designer, project manager, multi-disciplinarian or fancy specialist, I believe everyone can get something out of this talk, so join me!

Documenting components with stories
18 min
Documenting components with stories
Most documentation systems focus on text content of one form or another: WYSIWYG editors, markdown, code comments, and so forth. Storybook, the industry-standard component workshop, takes a very different approach, focusing instead on component examples, or stories.
In this demo, I will introduce an open format called Component Story Format (CSF).
I will show how CSF can be used used to create interactive docs in Storybook, including auto-generated DocsPage and freeform MDX documentation. Storybook Docs is a convenient way to build a living production design system.
I will then show how CSF stories can be used create novel forms of documentation, such as multiplayer collaborative docs, interactive design prototypes, and even behavioral documentation via tests.
Finally, I will present the current status and outline a roadmap of improvements that are on their way in the coming months.

You thought your React application is secure? Think again

You thought your React application is secure? Think again
Modern frontend frameworks like React are well thought-of in their application security design and that’s great. However, there is still plenty of room for developers to make mistakes and use insecure APIs, vulnerable components, or generally do the wrong thing that turns user input into a Cross-site Scripting vulnerability (XSS). Let me show you how React applications get hacked in the real-world.
React on Steroids with Nx!
27 min
React on Steroids with Nx!
We often talk and hear about scaling in production, but we rarely talk about scaling development. Aspects like structuring and organizing your codebase, code sharing across teams, speeding up build and test runs can play a huge role in terms of productivity for a developer team. That impacts small teams but gets even more evident as your team grows and especially for large enterprises.
In this short talk I'm going to demo Nx and what it can do for you to help you modularize your React code, generate code for you, help you build faster and much more. Tune in to learn about the build framework you've been missing in your tool belt!

The future of work is enjoyable
We’re generally afraid of the future. Not only is it unknown, but there’s quite a lot of reasons to believe we’re practically doomed. And it doesn’t help that we’re negatively wired nature, programmed to look out for risks more than search for rewards. Developers especially so.
So with this speech, I want to paint another picture for you. I genuinely believe, the future of work is enjoyable and definitely worth pursuing. And you can have that. Right after this speech.

Continuous Localization in Enterprise Web Projects
Did you know that 50% of users will NOT use the English version of your application, if it supports multiple languages? For ambitious high-growth businesses, going global is not "if" but "when" so it's important to recognize the importance of localization, especially in large multi-team projects. This discussion will explore the depths of localization in Agile companies and what can be achieved with a Continuous Localization system. I'll share some common issues we faced with multi-language products and how localization automation helped us to scale the process across many product teams within the company.
