React Amsterdam is a celebration of good things coming together: ReactJS that rocks and spring in Amsterdam that blossoms.

React Amsterdam is a full day two-track conference on all things React, gathering Front End developers across the globe in the tech heart of Europe. React 

Amsterdam is a heir to the biggest React community in BeNeLux and we have our priorities straight: only the highest quality content with careful balance of practical and visionary talks. 

React Amsterdam 2017 will take place in the Kromhouthal - former shipbuilding factory at a waterfront of Amsterdam City center.

Wix has been about cutting edge web development for a while, and we're all about TDD. When we started mobile with RN, we struggled to replicate our test-heavy workflow that we'd grown to love. We lacked tooling, best practices, and general know-how. 

In this talk, you'll hear about what works and what doesn't. You'll find out what methods we tried and rejected so you won't have to make the same mistakes, and you'll get pointers toward approaches that we've found work so you can get started on the right foot.

Testing & React Native: Lessons from the Battlefield

React popularized a new way of building user interfaces – components. By splitting our app into small, digestible parts the system as a whole becomes a lot easier to understand.

CSS was made in an era where documents were the height of the web. It doesn't fit easily into component-based systems, making styling one of the pain points of building React applications.

What if we took the best of JavaScript and the best of CSS, and combined them together to create the ultimate solution? Glen Maddern (CSS Modules co-creator) and I sat down and starting thinking about styling in this new paradigm. Let's talk about what we thought about and why we arrived where we did – 💅 styled-components.

Styling React/ReactNative Applications

React Native opens up the world of mobile development for many of us, front-end engineers. 

It not only allows us to use technologies we know already, like React, to provide first-class native experience to our users, but also to support many platforms, like Android and iOS at once, from within the same codebase.

This talk will explore various patterns that turned to be useful over the course of few projects I did. It will also demonstrate techniques that can be used to write truly universal apps, ie. ones that share core across web, native and more.

Universal React

"Reactive programming" still sounds scary to many developers. As if it is an elevated way of thinking, only accessible to the chosen few. Nothing is less true! It is the most natural way to look at programming problems. 

You just might not realize it yet! In this talk, Michel will demonstrate that many complex UI problems, such as form validation and routing, can all be seen as '*actions* that change *facts* which leads to *reactions*'. And as soon as we start distinguishing those concepts in our applications; our code will become more declarative, more concise and less imperative.

Complexity: Divide and Conquer!

A deep dive into how Pinterest migrated their web infrastructure to serve React pages, which required moving a huge amount of code without breaking the site. 

Details on the legacy stack (Django web server and Nunjucks/Jinja template rendering) moving to Node and migrating our templates to React.

Javascript has provided us with amazing ways to handle asynchronous logic to provide the best user experience possible. 

React Native is today the best tool to build mobile apps fast, but require extra care when managing asynchronous & offline logic: most people are often going to use your app with weak to no network.

Adding type checking to your code can be a frustrating experience at first. 

In this talk, Forbes will help you through that initial stage by identifying some of the problems you're likely to experience and giving you the tools to work through them. 

We'll cover adding types to code that initially looks too dynamic to type, adding runtime type checking (and whether that's a good idea) and finally, how you publish your type checked modules to npm.

Flow Typing a React Codebase

At Balsamiq we are rolling out our new web-app to production. A real-world application with real-time collaboration, built using Relay, Redux, node.js, Redis, etc., running on AWS using Convox. 

Even at small/medium scale, if you're serious about building a good product you will eventually have to build a complex stack. 

I will share a few lessons learned in the process: how to structure the code, implement reactivity, writing tests.

A Real-World GraphQL Application in Production

Many web developers haven’t explored WebVR yet. Building 3D Worlds was an intimidating endeavour. Especially with ReactVR there is no reason for that anymore. 

The talk kicks off with the basics of WebVR, shows how to build and navigate rooms using panos in ReactVR. 

Next it shows how to create a couple 3D meshes and how put together a small world using them.

Introduction to ReactVR

No other topic in software development probably has so much controversy as linting. With a wrong workflow linting can be really a pain and will slow you and your team down. 

With a proper setup though, it can save you hours of manual work reformatting the code and reducing the code-review overhead.

Make Linting Great Again

When you start out on React Native project, there is a certain sense of awe as the package manager delivers the first bundle to the simulator. You quickly add some hello world text and maybe even a Pokemon image. Things are really starting to look up… 

And then you need to add another view and you realize that you need to navigate somewhere. So you check out the React Native Docs and are quickly greeted by IOSTabBar, Navigation, and NavigationExperimental modules. 

With so many different options in the core codebase you realize that it’s still a bit of an unsolved problem. Now you’re looking at 3rd party integrations… and you start to wonder, just how should you implement navigation? 

This talk will outline the different approaches to navigation available in React Native and in the RN eco-system, and the pro’s and con’s of each solution.

The question is not how to avoid bugs when building software. There will always be bugs. 

The question is how quickly can you recover from them. 

Let's go through some ways you can give your app the ability to notify you of these bugs before your users do using React and Redux. 

Start pushing bugs to prod responsibly.

Pushing Bugs to Prod Responsibly with React and Redux

Testing UIs has always been a hard job. In the components era, there are new tools and solutions available that transform completely the way we approach testing. 

From snapshots, through end-to-end frameworks, to style guide testing. In this talk, we'll see some modern (and creative) testing solutions.

React Native mobile just got easier. Learn how to tap into rapid development by using what the pros are ready to give you!

Coding Mobile with the Pros

Code Push for React Native brings web like release agility to mobile apps by enabling developers to update apps instantly. 

This talk will cover the next iteration of Code Push and how it fits into a complete suite of DevOps services built for called Mobile Center, built for React Native.

Web Like Release Agility for React Native Apps

React Native allows for building great native apps by utilising native mobile components. Apparently handling touch and gestures is quite tricky as it often needs to interact with the application code which runs asynchronously in the javascript VM. 

This talk is going to be about how the gesture system has been designed and implemented in React Native and how to use it to stay out of trouble.

Advanced SSR Caching with React

React Native holds great promise in terms of excellent developer experience with JavaScript and code reuse between platforms. 

The big question is  - do these benefits come at the price of performance? How well can React Native hold its own against purely native implementations?
