React is fast and that is awesome, but as web developers we should continuously strive towards better and better performance. We deserve a smart, fast web since only a small minority of users has brand new smartphones and a 4G connection. In this talk we're going to talk about why performance & load time matters and how we can improve those two factors in React-based web applications.

A closer look at what's happening behind the scenes in your browser and how to use this knowledge to chase 60 FPS. You'll understand why certain CSS properties are better for animations and what are the most common performance bottlenecks in rendering pipeline.

With WebVR we are finally ready to create first-class Virtual Reality experiences using Open Web technologies. WebGL being able to render 3D graphics gives us infinite possibilities when building for the browser. These APIs allows VR content to be published and consumed on the Web almost instantaneously from any capable device. A-Frame brings the ease of use while following game development coding principles. Use simple HTML markup to create Virtual Reality experiences for all available platforms, and see how easy, fun, and fast it is.

Have you ever struggled with making dependencies between reducers? Have you ever stepped into problem with mulitple async operations done at the same time doing huge mess in your state? Let me be your guide into redux sagas with tips, how and when you can use them in your application to solve all side effects problems at once.

During this session, I will show how to use TensorFlow for solving Linear Regression problems and build Convolutional Neural Networks. We will train algorithms and use predictions of Machine Learning models in Frontend Application using REST API.

Recompose is an utility library advertised as Lodash for React. It provides a wide range of useful Higher Order Components to reduce the boilerplate. What does it bring to React? Will it make your code modular and reusable? Is it necessary to drink a latte from an avocado before using it? Be prepared to learn all that and much more during this talk, so buckle up and find out how to compose your components like a pro.

There’s a long-standing myth in the mobile world that only native apps are able to provide a decent performance for the mobile user. With the emergence of Progressive Web Apps that suppose to mimic all the native goodness, the push for performance in the mobile web is now stronger than ever before. Is the Web Platform ready to keep up with these expectations? This talk is a wide overview of the many practices and strategies we can employ to satisfy our mobile users’ needs - from the HTTP-level tweaks via load and render time optimization to smooth scrolling and animations tricks.

Drowning in a pile of buzzwords, have you ever come across word “GraphQL”? Whether it’s a total unknown for you or you are unsure if you should give it a try or not, it’s a perfect talk for you. I would like to share my hands-on experience of using GraphQL and introduce you to its basic concepts. After this talk, you will know what GraphQL is and when it’s useful. You will be able to tell queries, mutations and subscriptions apart. Additionally, I would like to show how easily you can start with it, using Apollo. Hopefully, my talk will give you knowledge and motivation to give it a shot.

You will learn how to setup your project for Docker Builder Patter. I will talk how to build your application and publish in on production as small as possible without any dev dependencies or even serverless. I will show how to automate building and deploy the application using CircleCI and publish the results to our public Docker hub. On to of that, we will run the output image on AWS ECS live on production.

There’s a lot of misconceptions around Vue when it comes to things like templates vs JSX, two-way data bindings, watchers, mutations. It might be very surprising to know that some problems that Fiber solves for React don’t even exist in Vue in the first place. Not just performance-wise.

So you built a Node.js web application and got it to run. What's next? This talk introduces you to diagnosing execution, performance and memory usage of your app. You'll learn about new and old tools for diagnosing memory consumption and leaks, CPU profiling and more. Skills you don't use every day, but when you do, you prevent a disaster from happening. The overview of tools starts at basic tools anyone can use and reaches the newest additions to Node.js 8.0.
