TL;DR: A follow-up to my React Conf talk, recorded online during COVID. I talk about the same app a year later, and what it's like to run React Native in production.
In May 2020, when everything had moved online because of COVID, I spoke at JS VidCon about how we use React Native at Olio to reduce food waste.
It's part 2 of the React Conf 2019 talk: the same migration (3 months, 3 developers, millions of users), a year later.
What held up Most of what we did first still worked a year later: the performance monitoring, the testing patterns and the code structure.
What we changed As the app and the number of users grew, some things had to change.
The reality of React Native in production What it takes to maintain a React Native app people use every day: releases, debugging and developer experience.
JS VidCon was one of the first fully remote conferences during the pandemic, so the format was very different from React Conf.
Update: The recording of this talk is no longer available online. The JS VidCon YouTube channel was hacked a few years ago and the backup couldn't be recovered.
