ExpoOTA Updates.
Push instant updates to your Expo app — skip the EAS rebuild and the app store queue, with rollbacks and percentage rollouts built in.
Over-the-Air Updates for Expo
Deploy JavaScript and asset updates to your Expo app without an EAS rebuild or store review. Works in the managed workflow with full rollback and staged-rollout control.
import { AppSpacer } from "@appspacer/expo";
await AppSpacer.init({
apiKey: "your_deployment_key",
updateStrategy: "onInit",
});How It Works
Three steps to ship Expo updates at the speed of thought.
Push your latest build
Use our CLI or wire it into your CI/CD. A single command bundles your assets and ships them to the global edge network.
Delta diffing
Our diffing engine computes the change set between versions, so only what changed is shipped — minimal bandwidth, instant delivery.
Instant update on device
The SDK fetches the manifest, verifies checksums, applies the update, and reports install status for billing and telemetry.
One Init. Done.
Call AppSpacer.init() once at startup. The SDK fetches the manifest, verifies checksums, applies changed assets, and reports install status automatically.
Advanced Capabilities
Everything you need to orchestrate global Expo rollouts with confidence.
Instant Update Delivery
Push code and asset changes directly to devices. No app store review, no waiting — updates arrive in seconds, not days.
One-Click Rollbacks
Every deployment is versioned. Instantly revert to any previous release without data loss or downtime.
Server-Side Staged Rollouts
Canary and percentage-based targeting enforced on the server. Release to 1%, 10%, or 100% with deterministic bucketing.
Hardened Security
End-to-end encrypted delivery with SHA-256 checksum verification on every asset before it is applied.
