What it does
Lists are a pain in RN. They can be a perf nightmare and who likes blank cells? Today, FlashList offers: - Up to 5X FPS in UI Thread - Up to 10X FPS in JS Thread - Easy migration We've already shipped it in some of our apps & we're excited for you to try it!
Creating a performant list in React Native is not easy. But with FlashList, you get incredible performance using the familiar React Native FlatList
Even with the similar props as the React Native FlatList, FlashList recycles components under the hood to maximize performance. * Average FPS on a 60FPS screen Android Moto G10 device. (Higher is better) Some libraries allocate more items in memory to achieve good performance. FlashList does not recreate items as a user scrolls, making it noticeably more memory efficient. FlashList is especially easy-to-use thanks to FlatList's API. Simply change the name of your component and you are good to go. On iOS, other lists perform well, but on Android, they fall short. FlashList performs well even on low-end Android devices. Apart from FlatList props, FlashList offers a set of extra props to tweak…from shopify.github.io

Talanoa▲341Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hello, HN - I wanted to share this puzzle game I made during my vacation. I'm rather fond of the pipes puzzle where your goal is to restore a scrambled network of connections by rotating tiles. It's usually played on a grid of squares and this all started when I decided to make a programmatic solver for that kind of puzzle. Then I realized that with some minor changes the solver could generate new puzzle instances. I thought about what kind of puzzle to make and someone suggested a hexagonal grid. Adapting the generator wasn't too hard but then I had to create a way to play this variant. So…
