CBQueue

library0.0.11jsnpmunverified

Generic callback queue using promises for managing async task execution with priority support. Current version 0.0.11 is early-stage with minimal adoption. Provides a lightweight alternative to full-featured async queues like Bull or Bee-Queue, but lacks persistence, monitoring, and production hardening. Ships TypeScript types. Low release cadence.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

CBQueue

✓ import { CBQueue } from 'cbqueue'

✗ import CBQueue from 'cbqueue'

Named export only; no default export.

Priority

✓ import { Priority } from 'cbqueue'

✗ import { PriorityEnum } from 'cbqueue'

Priority is an enum, not a string union.

Task

✓ import type { Task } from 'cbqueue'

✗ import { Task } from 'cbqueue'

Task is a TypeScript type; use import type for type-only imports.

Creates a queue, enqueues two tasks with different priorities, and processes them sequentially.

import { CBQueue, Priority } from 'cbqueue'; const queue = new CBQueue(); const task1 = () => Promise.resolve('Task 1 done'); const task2 = () => Promise.resolve('Task 2 done'); queue.enqueue(task1, Priority.NORMAL); queue.enqueue(task2, Priority.HIGH); queue.process(async (task) => { const result = await task(); console.log(result); });

Debug

Known issues

gotchaCBQueue does not automatically process tasks; you must call .process() explicitly.

fix

Call queue.process(handler) after enqueuing tasks.

affects: >=0.0.0

gotchaEnqueuing a task while processing is active may cause tasks to be processed out of order or skipped.

fix

Enqueue all tasks before calling .process(), or use a separate queue instance.

affects: >=0.0.0

gotchaPriority levels are only advisory; the queue does not guarantee strict priority order.

fix

Do not rely on priority for critical ordering; use a dedicated priority queue library.

affects: >=0.0.0

Errors

Common errors & fixes

TypeError: queue.process is not a function

Calling .process() on a non-existent method; likely due to wrong import or version mismatch.

fix

Ensure you import CBQueue as a named export: import { CBQueue } from 'cbqueue'

Uncaught TypeError: Cannot read properties of undefined (reading 'then')

Task function did not return a promise.

fix

Ensure each task returns a Promise (or async function).
