EAS Update

EAS service - costs apply. EAS Update is available on the Free plan; publishing and delivery use update, bandwidth, and storage allowances, with higher limits on paid plans. See https://expo.dev/pricing.

Use EAS Update to deliver compatible JavaScript, styling, and asset changes to installed apps without submitting a new native binary. Native-code changes still require a new build.

Start with the supported configuration path

Before changing anything, inspect package.json, the Expo app config, eas.json if present, and whether ios/ or android/ are tracked. Use what you find when reviewing the CLI's changes:

• Preserve existing dynamic or platform-specific app configuration.
• If eas.json exists, preserve its profiles and existing channel assignments. The CLI adds a channel matching the profile name only to build profiles that do not already have one.
• If eas.json is absent, do not create it by hand. The CLI may direct the user to run eas build:configure separately.
• With tracked native projects, expect the CLI to synchronize the platform's native Update configuration. Without them, expect Continuous Native Generation to apply the native configuration during a later build.

Detect the Expo SDK version before installing packages or interpreting version-specific behavior.

If expo-updates is not installed, install the SDK-compatible version:
