Import
import { composeRefs } from "@typed/ui/Dom/index";This public exposure is a re-export. Its import path is supported; declaration documentation is shared with the other public exposures below.
Signatures
export declare function composeRefs<const First extends RefInput | null | undefined, const Second extends RefInput | null | undefined = undefined>(first: First, second?: Second): ComposedRef<First, Second> | undefined;Why
A component’s internal ref and a caller’s ref both need the real mounted node. Each return value may be void, Effect, Stream, or Fx, and composition normalizes those forms without hiding failures or services.
Ownership and lifetime
The first ref runs before the second. Streams and Fx values are drained in the caller’s Scope and interrupted on unmount. The function throws synchronously when both refs claim hydration ownership because applying two serialized states to one element is ambiguous.
Examples
import { composeRefs } from "@typed/ui/Dom/Refs"
import { Effect } from "effect"
const ref = composeRefs(
(element: HTMLButtonElement) => Effect.sync(() => element.focus()),
(element: HTMLButtonElement) => console.log(element)
