Observe measures how fast your Expo app starts and how fast each screen becomes usable, on real user devices. Install the library, wrap your root layout, and startup metrics arrive with nothing to instrument. Every native build and every EAS Update gets its own marker on the chart, so you can see which release moved the line. Full device context on every session: model, OS, country, network type, thermal state, frame data. Free plan covers 100K events a month.
Expo enables you to build cross-platform native apps using only JavaScript.
In addition to React Native components, you'll have access to the Expo SDK, a library that provides a wide range of native APIs on iOS and Android. Expo can also manage assets for you, handle push notifications, and build your native binary for submission to the app store.
I'm curious how people build local-first apps. I don't need full CRDT support, but more just syncing with a "parent" db (both pulling new data and pushing locally created records). I see tinybase which feels maybe a bit more powerful than what I need (?).
I also see livestore which feels scary to build on something that new. Is there a non-hack way to use sqllite and sync to a postgres db? Basically my criteria in order of importance would be: 1. stays out of my way (easy to deploy, migrate, use) 2. has leverage with types (a standard linter tells me I'm blowing up the app with the code I just wrote) 3. stable (I would ideally just learn a "goto" tool and use that on all projects going forward)

Preview release of web support in Expo! Using React Native you can rapidly develop native apps, websites, trusted web apps (TWAs), desktop and mobile PWAs. This uses react-native-web, which was created by Nicolas Gallagher to build the Twitter mobile website.
