Sometimes (for development in particular) it's useful to clear all state on the device related to a project. This could be exposed either as a function or a button in the Expo UI somewhere.

Flutter has something like this and I think it would be beneficial. Here is how it works: expo-image will have a prop called 'syncPlayback' which makes all animated images with the same source have synced playback no matter when it was rendered. Maybe a global clock? For example, if an expo-image was rendered right away and 2 seconds later you pressed the 'render same image a second time' button. Both images would have synced playback. If you would like a real life example, it would work near identical to how twitch.tv handles animated emotes.

In MediaLibrary it says: // Note: PhotoKit defaults to a deliveryMode of PHImageRequestOptionsDeliveryModeOpportunistic // which means it may call back multiple times - we probably don't want that imageOptions.deliveryMode = PHImageRequestOptionsDeliveryModeHighQualityFormat; Code here: https://github.com/expo/expo/blob/sdk-53/packages/expo-media-library/ios/MediaLibraryImageLoader.m#L78-L80 However, there're tons of photo apps out there that needs the feature to actually load a low-res image first during scrolling, and only when user stop at certain place, load the actual high-res image from the media library. The performance improvement is very significant. Please consider adding this feature by allowing passing in an optional switch to use PHImageRequestOptionsDeliveryModeOpportunistic. This will benefit us greatly as well as tons of other social/photo apps out there using expo

The current workflow for E2E tests is to rebuild the app every time you run tests. This works for version based release cycles but does not work well with CI/CD and using EAS Updates OTAs the way they're intended. There's an option to export the bundle for Android and iOS with expo export but there's no way to feed it to the app easily. The manifest is not compatible, the EAS Updates expects update server to be implemented etc. The only way to have this running is by running expo start and hoping the bundle will build in enough time for the E2E test to pick it up which is not reliable. It would be great if there was an easy option to: Prebuild the JS bundle with an option to cache it in CI Feed this prebuilt bundle with assets to the expo-dev-client version of the app (minimal updates server that outputs the same manifest.json as the dev one) This would allow running Maestro tests over the app on every PR instead of on every App Store release.

please make expo be able to use the deno runtime. u alredy support the bun runtime and it would be perfect if we had a similar command to this: bun create expo this would really be a thing for expo projects because deno is able to provide a beautiful development experience to the devs

Basically provide an api to pass a custom google maps theme with customized layers and colors

Expo should add an Accept header to HTTP queries used to load images, with the list of supported formats (see https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/Accept ) This allows on-the-fly image format selection, to serve the most optimised file supported by the device (for example with https://docs.imgproxy.net/configuration/options#avifwebpjpeg-xl-support-detection )

A similar feature request is opened for react-native-app-auth. Not sure if this has to be done there as well, before it could be managed in expo. Using ASWebAuthenticationSession will automatically present a mandatory dialog box asking the user to give explicit consent for accessing the website’s data. This consent screen shows product and domain name. Our customers are always irritated, what this will mean. New customers also immediately leave the app. Because there is no way to describe that the data is not shared with 3rd parties. iOS 13 may omit the dialog by configuring ASWebAuthenticationSession for a private session using the new prefersEphemeralWebBrowserSession parameter, which needs to be set before start is called. https://github.com/FormidableLabs/react-native-app-auth/issues/428

Support the iOS 13 ASWebAuthenticationSession in expo-web-browser
