@lauf/queue v2.0.0

Minimal in-memory message queue

A Typescript queue implementation with...

• a Promise-oriented, Generic API to build your own event loops
• queue limits to facilitate backpressure
• immutable queue state to facilitate time-travel debugging

Read the API Reference or the reference usages below.

Usage

// Create a queue that accepts any values
const queue = createQueue();

// put an event in the queue
queue.send({
  kind: "move",
  x: 200,
  y: 200,
});

// block until next event is available
const action = await queue.receive();

// define an event type
interface Coordinate {
  x: number;
  y: number;
}

// Create a queue for typed events
const typedQueue = createQueue<Coordinate>();

// block until next event is available
const { x, y } = await queue.receive();
