Effect × Expo
Reliable Expo APIs, by construction.
Effect-native APIs for Expo, starting with a compatibility suite that validates the native surface before you build on it.
- Pinned runtime
- Effect 4 RC
- Target SDK
- Expo 57
- Current work
- Capability prototypes
Compatibility harness
resolving contractimport { Battery } from "@better-native/battery"
import * as Effect from "effect/Effect"
const power = Battery.getPowerStateAsync.pipe(
Effect.provide(Battery.live),
)
01 Resolve
02 Run
03 Result
The same execution model, from device to service.
01 / Foundation
Compatibility is a feature, not a footnote.
A disciplined bridge between Effect and the Expo ecosystem.
The harness tests each capability package against a concrete surface derived from pinned upstream revisions.

The operating model
One predictable path from native work to application code.
Validate
Execute a real compatibility denominator before abstraction.
Compose
Expose Effect-native capabilities with typed errors and requirements.
02 / Roadmap
Build the base once. Let every capability inherit it.
- Now
Capability prototypes
Battery, Network, KeepAwake, and SecureStore on the shared harness.
- Next
Native evidence
Expand paired device runs and blind developer-experience pilots.
- Then
Developer preview
A stable surface for application teams to evaluate in production.
Questions, before code
A small surface, with deliberate decisions.
