injectQueuer

Call Signature#

function injectQueuer<TValue>(fn, options?): AngularQueuer<TValue>;

Defined in: packages/angular-pacer/src/queuer/injectQueuer.ts:102

Creates and manages an Angular Queuer in the current injection context.

Processes queued items in order with configurable pacing, capacity, and priority.

Options and state#

Accepts static options or an options factory. Factories are read lazily, and signal dependencies update the existing core instance. Local options override provider defaults. Methods apply current options before executing and schedule work outside Angular's zone. The provided function runs inside Angular's zone.

Pass a selector to expose reactive core state through state(). Without a selector, state() returns {}; operations remain available on the ref.

Cleanup#

The default cleanup is to stop automatic processing. Set onUnmount to replace it.

Type Parameters#

TValue#

TValue

Parameters#

fn#

(item) => void

The callback invoked by the core utility.

options?#

MaybeAccessor<AngularQueuerOptions<TValue>>

Core options or a reactive factory returning them.

Returns#

AngularQueuer<TValue>

A ref containing stable methods and a readonly selected-state signal.

Example#

// In a component or service injection context.
const utility = injectQueuer(
  (item: string) => console.log(item),
  () => ({ wait: 100 }),
  (state) => state.items,
)
utility.addItem('job')
console.log(utility.state())
