🗣 Talks

➡️  Lu Wilson – How to make Make Real with tldraw

We recently re-wrote our selection feature for tldraw, a digital whiteboard. To make it work, we first needed to teach our whiteboard to see the canvas without first rendering it, and then to capture the (surprisingly! extraordinarily!) complex logic behind a simple click.

➡️ Taz Singh – Wait, you're using React Native on the Web?!

In this talk, I will dive into the skepticism of building React Native Apps for the Web, including everything from design systems and navigation to ExpoGL and Reanimated, from how they’ve successfully built Guild on top of this architecture.

➡️ Sanket Sahu – Building Universal Tools for Web & Mobile In this talk, I’m diving deep into how to build universal libraries that work on all platforms – a React Native first approach that works everywhere including the browsers! Together, we’ll explore the nitty-gritty challenges and innovative solutions associated with creating tools that seamlessly bridge the gap between web and mobile platforms. Expect a concoction of creativity, practicality, and actionable insights as we journey from idea to implementation.

➡️ Open Mic Lightning Talks – every attendee is welcome to speak (<5min)

What's wrong with GraphQL‽


Wow, has it been a rough year for GraphQL or what? People have said a lot of things, made a lot of videos, and spread a lot of hot takes. 🔥

What's true? What's overblown? Join Taz Singh and Robert Balicki at Pinterest's New York 🗽 office as they sort through the Internet's most 🌶️ takes in a live (and lively!) discussion.

🎤 This will be an open format, meaning it's your opportunity to share your qualms, complaints, and observations. Audience participation will be encouraged. The folks on stage are there to facilitate and fill in the gaps from their experience. 🙌

Taz has been working with GraphQL since 2016 on a wide variety of architectures, from social to IoT to high mobility peer-to-peer mesh. He is particularly fond of interesting authorization mechanisms in a performant manner.

Matt works on GraphQL for Meta's mobile apps, and is a member of the GraphQL Foundation's Technical Steering Committee. He wants to help GRaphQL find a footing beyond the JS and React ecosystems.

Robert was on the Relay team at Meta/Facebook and is currently at Pinterest. He is the author of Isograph, "the best way to build React apps backed by GraphQL data".

And you, the audience. ❤️

Afterward, we will head to a nearby bar to hear everyone's truly unfiltered thoughts about GraphQL 🍻
