Talks:

1st Talk: Boda Zhao

"Astro for React Developers: What You Need to Know"

After migrating NewDay's Platform Portal from Gatsby to Astro, it changed how we think about building for the web. In this talk, Boda shares why we picked Astro, what React developers need to know when moving from SPAs, and the lessons we learned about state management, server/client boundaries, and Astro's unique architecture.

2nd Talk: Chun Chan

"I built a react component and all I got was eternal responsibility"

In this talk I’ll share what I’ve learned as the sole maintainer of the package "react-currency-input-field". What started as a small weekend side project, now has over 1M+ monthly downloads on npm. I'll go through some of the lessons I've learnt as it has grown: triaging issues, evaluating feature requests, and answer the important questions: How much money do I actually make from it? And does it help in job interviews?

Full agenda:
6:00 PM: Doors Open. Grab a pizza slice, sip a beer, and start chatting with other attendees.
