Variable Ref

Type Declaration

• make: <A>() => Effect<Ref<A>, never, Scope>

  Create a Ref to hold a mutable reference to a value.

  Example

  // For DOM elements
  const inputRef = yield* Ref.make<HTMLInputElement>()
  
  // Later, focus the input
  yield* inputRef.value.pipe(
    Effect.tap((el) => Effect.sync(() => el.focus()))
  )
  
  // For any value
  const cleanupRef = yield* Ref.make<() => void>()
  cleanupRef.current = () => console.log("cleanup")
