Task Buffer

Manages concurrent task execution by enforcing a maximum limit on simultaneously active operations.

When this limit is reached, the TaskBuffer automatically queues additional spawn requests and processes them in order as capacity becomes available. This prevents resource overload while ensuring all tasks are eventually executed.

import { run, sleep } from "effection";
import { useTaskBuffer } from "@effectionx/task-buffer";

await run(function* () {
  // Create a task buffer with a maximum of 2 concurrent tasks
  const buffer = yield* useTaskBuffer(2);

  // These tasks will execute immediately since they're within the limit
  yield* buffer.spawn(() => sleep(10));
  yield* buffer.spawn(() => sleep(10));

  // This task will be queued until one of the running tasks completes
  yield* buffer.spawn(() => sleep(10));

  // Wait for this specific task to complete
  yield* yield* buffer.spawn(() => sleep(10));

  // Wait for all spawned tasks to complete
  yield* buffer;
});
