ut-queue

library6.2.3jsnpmunverified

UT Queue is a generic queue management library for Node.js, part of the UT framework (softwaregroup-bg). Current stable version is 6.2.3, released as part of the UT monorepo. It provides message prioritization, overflow handling, rate limiting, timeout handling, and metrics. Unlike simple queue libraries, it offers a contextual queue API tied to connection IDs (conId), allowing per-connection queue management. Primarily used within the UT ecosystem, it's less suited as a standalone general-purpose queue.

Code

Verified usage

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

queues

✓ import { queues } from 'ut-queue'

✗ const queues = require('ut-queue')

ESM only (the package exports an ES module).

queues

✓ const { queues } = require('ut-queue')

✗ const queues = require('ut-queue').default

CJS require pattern: destructure the named export 'queues'. No default export.

queues.create

✓ const q = queues.create({ context, callback });

✗ queues.create()

Method is on the `queues` object, not default import.

Shows create, get, delete, and count operations using context with conId.

import { queues } from 'ut-queue'; const q1 = queues.create({ context: { conId: 'my-queue' }, callback: () => console.log('queue ended') }); console.log('Queue count:', queues.count()); const q2 = queues.get({ conId: 'my-queue' }); console.log('Queue retrieved:', q2 === q1); queues.delete({ conId: 'my-queue' }); console.log('Queue deleted, count:', queues.count());

Debug

Known issues

breakingVersion 6.x dropped support for CommonJS require without destructuring?

fix

Use named import or destructure require.

affects: >=6.0.0

gotchacontext.conId must be a string or value that serializes correctly; otherwise queues.get may not find the queue.

fix

Ensure context.conId is a consistent unique identifier (e.g., string).

affects: *

deprecatedOlder versions (pre-6) may have exported a default function; check import path if upgrading.

fix

Update import to named export { queues }.

affects: <6.0.0

Errors

Common errors & fixes

TypeError: queues is not a function

Using default import `import queues from 'ut-queue'` but the package exports a named export.

fix

Use `import { queues } from 'ut-queue'`.

Cannot find module 'ut-queue'

Package not installed.

fix

Run `npm install ut-queue`.

queues.create is not a function

Importing the module as a function instead of an object with methods.

fix

Ensure you use `import { queues } from 'ut-queue'` and then `queues.create()`.
