TypeScript for React Developers

Forbes Lindesay

In this workshop we'll take a simple React application written in JavaScript, and convert it into TypeScript. You'll see how TypeScript lets you work faster, with fewer bugs making it to production.

- We'll start configuring our app to build using TypeScript
- We'll add types to our codebase to both catch errors and better document our code
- We'll enable strict mode to catch even more errors
- We'll see how to use generics to add types to functions without reducing their flexibility
- We'll enable tslint and fix some of the issues it throws at us

During the workshop, you will learn how to interpret the errors TypeScript throws, and how to build the most robust type system possible.

Thursday 9:00 - 13:00 Room Terra Lucis I

Functional Programming concepts in JavaScript

Flavio Corpa

This workshop will walk you through many concepts from functional programming brought to javascript, starting easy with curry, compose and map and slightly increasing the difficulties to Maybe, Either, Task monads, etc... hope you enjoy the journey!

Thursday 9:00 - 13:00 Room Almirante

Thursday 14:00 - 18:00 Room Almirante

Hooked on React Hooks

Braulio Díez

Hooks have been introduced in a React minor version update, but they have become a fundamental change in the way of developing react components, they let you use state and other React features without writing a class.

- Learn the core concepts
- Learn how to use standard hooks (useEffect, useContext, useReducer...).
- Learn how to create custom hooks.
- Deal with component life cycle.
- Provide guidance on how to migrate a class components to functional components.
- Cover unit testing + hooks.

Thursday 14:00 - 18:00 Room Terra Lucis II

Advanced Async Flows with Redux Saga

Nacho Martín

The simplest case for asynchronous data flow (make a request to an API, process the response), can be handled very well out of the box, but what happens when we face more complex scenarios? Redux Saga is a powerful that, that once tamed we can use to model all kinds of scenarios. In this workshops we will see how take advantage from it to orchestrate side effects, avoiding callback hells or complex promise chains, in a readable and declarative way.

Thursday 14:00 - 18:00 Room Terra Mitica

React Native performance and best practices

Eugene Zharkov

Are you familiar with things like code bloat, computation speed and platform limits which are blocking application UI? You want to run your code as fast as you can, because user counts each second to have a positive experience. We will take a look under the hood of React Native, application performance issues, learn how to analyze and measure. Consider common application architecture patterns and component building mistakes and will apply best practices, as well as non-standard solutions to fix those issues.

Refactoring off the hook(s)

Marco Cedaro

React 16.8 introduced hooks, a concept that will change the way we write React components and apps.

This talk will walk you through the refactoring of an existing React app with hooks: we will go through the theory as well as seeing the available hooks in a real world scenario.

Friday 9:45 - 10:30 Room Europa

Type-level Programming ƒun in TypeScript

Mattia Manzati

The TypeSystem is our friend when coding, and it saves us from innumerable hidden bugs. When we encounter functions with a very dynamic nature, our types may not be enough, and we end up having to perform countless casts by hand, introducing human errors. Can we improve our types? Can we teach the compiler how our data structures behave at type level? In this talk we will see together what type-level programming is, and how to introduce it in our codebase helps us to reach more exact type definitions, thus reducing the bugs in our code. Starting from a practical example we will see the basic patterns, limits and potential.

CSS. Under the hood.

Kasia Jastrzebska

With react we have a lot of freedom when it comes to choose our tools. We make a pick based on developer experience, rating on github ;), performance. I would like to talk a little bit about how different ways of applying CSS to our code (css classes, inline styles, css-in-js) impact browser behaviour. Lets deep dive into DOM and CSSOM building processes and actually check it out.

Friday 11:45 - 12:30 Room Europa

Evergreen Legacy Applications

Harry Wolff

While most of the world is excited about all the newest and coolest technologies you’re stuck maintaining a legacy application. It’s not glamorous, but it works and pays the bills. What if you could have the best of both worlds? Keep your legacy application and use the latest and greatest tools?

This dream can be your reality. I’m here to share some of the techniques, ideas, and code I’ve used to make this dream come true. While the task may seem daunting, if you come to this talk you’ll learn strategies you can use to slowly migrate your legacy application to become evergreen.

Friday 12:30 - 13:15 Room Europa

Giving voice an action in React and React Native

Wouter van den Broek

Voice is the next frontier for input on (mobile) devices and the web. You can use it for inputting text instead of a keyboard but better use it to do actions on your mobile or website. This can be opening a task or screen in your app or even process it with NLP (natural language processing) to get the users intention and create a magical experience.

In this talk you will see how to get voice input ready in React and React Native, how to react on voice input and how to process it to get the intent from the user voice.

Friday 16:15 - 16:40 First floor

Friday 16:45 - 17:30 Room Europa

Testing in React Native: Unit & E2E

Preeti Wadhwani

Every day we write a hundred, thousand lines of code to build products in the aim of impacting the lives of people in a positive way. But how can we make sure that the key features the user uses do not stop working with every new deployment? How can we get confidence that when refactoring code the existing feature still works as expected?

This talk I am going to share with you my experience of dealing with these in React Native by moving towards TDD. Also how writing unit and e2e tests helped me write better code and build beautiful apps.

Friday 17:30 - 18:15 Room Europa

“Micro Frontends”- You Keep Using That Word, I Don’t Think It Means What You Think It Means

Shem Magnezi

"Micro Frontends" is the new buzzword in the Frontend world, but too many times people use it in the wrong context or with different things in mind.
Micro Frontends can refer to different kinds of solutions that solve different types of problems - starting from using different UI frameworks on the same app or letting different teams work on separate parts of the code independently.
In this session, we'll go over the different problems we have when building a big app and how different micro-frontends solutions can help with this.

Mind-Reading with Adaptive and Intelligent User Interfaces

David Khourshid

When it comes to UX, one size doesn't fit all. What if you could predict user behavior and create custom-tailored, smart UIs? In this talk, we will explore how we can make adaptive and intelligent user interfaces that learn from how individual users use your apps, and personalize the interface and features just for them, in real-time. With predictive analytics, probability-driven statecharts, decision trees, reinforcement learning and more, UIs can be developed in such a way that it automatically adapts to the user's behavior.

Saturday 9:45 - 10:30 Room Europa

Profiling React rendering performance

Sergey Ryzhov

Rendering is not a common performance bottleneck in React applications. It’s more about large bundle sizes or slow network requests. At the same time rendering problems can be challenging to discover and mitigate. So when user experience gradually becomes more and more janky most of us just use an old-school debugging technique “comment out this line of code, refresh and see if something changed”. This is not optimal and there are better approaches to performance profiling.

We are going to use Chrome Perfomance Tab and new React DevTools Profiler plugin to profile a real application. We will learn how to use these tools to identify rendering problems and make user experience really smooth. We are going to explore different React optimization techniques that allow us to avoid unnecessary rerenders or doing heavy computations on every render (memo, useMemo, useCallback).

We are also going to touch how experimental Profiler component can be used to collect timing information and measure the "cost" of rendering.

Paving the adoption path of your Design System for engineers

Jeremias Menichelli

Design systems are popping up in all companies to help developers build interfaces faster while staying consistent with the design of the product. It might happen that your company has one, but your teams are not using it or they are stuck in an old version of it.

Not all design system codebases are created in the ideal context and conditions. I’m going to show you how in Typeform we are battling tech debt, building straight forward processes and infrastructure, to help our teams move forward as our design system evolves.

Saturday 11:45 - 12:30 Room Europa

Testing in Production

Talia Nassi

How do you know your feature is working perfectly in production? And if something breaks in production, how will you know? Will you wait for a user to report it to you? What do you do when your staging test results do not reflect current production behavior? In order to test proactively as opposed to reactively, test in production! By testing in production, you will have increased accuracy of test results, your tests will run faster due to elimination of mock and bad data, and you will have higher confidence before releases. You can accomplish this through feature flagging, continuous delivery, and data cleanup. Only when your end-to-end tests pass in production will you know that your features are truly working. I will show you how to mitigate risk, improve your understanding of the steps to get there, and shift your company’s testing culture to provide the best possible experience to your users. I will talk about the way to run tests in the production environment of a system, how to do it without disrupting real end users, and how to exclude testing data from data and analytics. I will also talk about the tools that help in this process, the benefits of testing in production and why the pros outweigh the cons, over doing it in staging or other testing environments, why its more reliable, and sometimes even easier.

Saturday 12:30 - 13:15 Room Europa

Resolving real-world problems by mixing several advanced React patterns and features

Mario Beltrán

Those examples about how to customize the theme of your app or that toggle component sample are fine to see the basic use case of new React patterns and features, but they are not enough to see how powerful these techniques are. In this talk we will see in depth how to put together most of the recent React advanced patterns and features (Compound Components, High-Order Components, State Initializers, Context API, Refs and -of course- Hooks!) to solve complex real-world problems in a simple, yet elegant way, including proper automated tests for them.

React Native at Skyscanner: The Good Parts

Karan Thakkar

In this talk, Karan will share his learnings from working on the React Native infrastructure at Skyscanner. These are concepts, issues and roadblocks that a developer would encounter in their journey of integrating React Native in a brownfield app. Knowing these ahead of time would help folks take the right decisions when building their own React Native infrastructure.

Monorepo: React Web & React Native

Eugene Zharkov

There are cases when product has a lot of business logic and want's to share it across web and mobile platforms, especially when the web part uses React and mobile - React Native. Sharable code adds development speed, simplified communication between teams, removes behaviour differences between web and mobile. At the same time there are a lot of things which can increase a solution complexity and add some limits to the final product.

Saturday 17:30 - 18:15 Room Europa

High performance video editing for the mobile web

Forbes Lindesay

At Threads we needed to add video editing to our mobile web app, including advanced overlays and filters. We thought there would be an open source project we could use as a foundation, but it turned out that every project we tried was either far too slow, or had a fraction of the feature set we needed.

By combining a canvas rendering strategy with invisible React UI for manipulating video overlays on the client side, and ffmpeg on the backend, we were able to build a video editing experience in a matter of weeks that supports near pixel perfect previews that can be edited in real time, and highly optimised mp4 output for the fully rendered videos.

In this talk, I'll take you through our approach, and why we arrived at the method we chose. You'll see some of the techniques that were required to scale our canvas solution, both managing the growing complexity, and keeping a lid on our memory usage.

This talk will be especially useful to anyone considering building high performance graphics for the browser, but it will also give any developer some new ideas about how to approach technical challenges.

Saturday 18:15 - 19:15 First floor
