interval-queue

library1.0.4jsnpmunverified

interval-queue is a lightweight Node.js utility library (v1.0.4) for managing periodic task execution. It provides a simple API to create, delete, and clear intervals with time units in milliseconds, seconds, minutes, or hours. Unlike raw setInterval, it offers centralized management and typed return values. Actively maintained with TypeScript types included. Suitable for scheduling repeated tasks in server-side applications.

Code

Verified usage

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

createInterval

✓ import { createInterval } from 'interval-queue'

✗ import createInterval from 'interval-queue'

This package uses named exports; default import is not available.

deleteInterval

✓ import { deleteInterval } from 'interval-queue'

✗ const { deleteInterval } = require('interval-queue')

Package is ESM-only; CommonJS require returns undefined.

createIntervalSecond

✓ import { createIntervalSecond } from 'interval-queue'

Convenience function that takes seconds instead of milliseconds.

clearIntervals

✓ import { clearIntervals } from 'interval-queue'

Stops all intervals managed by the package.

Creates a 2-second interval, deletes it after 10 seconds, and clears all intervals after 15 seconds.

import { createInterval, deleteInterval, clearIntervals } from 'interval-queue'; // Create an interval that runs every 2 seconds const interval = createInterval(() => { console.log('Task executed'); }, 2000); // Delete a specific interval after 10 seconds setTimeout(() => { deleteInterval(interval); console.log('Interval deleted'); }, 10000); // Clear all intervals after 15 seconds setTimeout(() => { clearIntervals(); console.log('All intervals cleared'); }, 15000);

Debug

Known issues

breakingThe package uses named exports only; default import or require() will fail.

fix

Use named imports like `import { createInterval } from 'interval-queue'`.

affects: >=1.0.0

gotchaIntervals are not automatically cleaned up when the process exits; you must call clearIntervals() to avoid hanging.

fix

Call clearIntervals() before process exit or in cleanup hooks (e.g., process.on('exit', clearIntervals)).

affects: >=1.0.0

gotchaThe deleteInterval function expects the return value of createInterval, not a number or string.

fix

Store the return value of createInterval and pass it to deleteInterval.

affects: >=1.0.0

deprecatedNo deprecation warnings in this version.

fix

N/A

affects: >=1.0.0

Errors

Common errors & fixes

TypeError: createInterval is not a function

Default import used instead of named import.

fix

Replace `import createInterval from 'interval-queue'` with `import { createInterval } from 'interval-queue'`.

ReferenceError: deleteInterval is not defined

Using CommonJS require() which returns undefined for named exports.

fix

Change to ES module import or use destructuring: `const { deleteInterval } = require('interval-queue')` does not work; switch to `import { deleteInterval } from 'interval-queue'`.

Error: loop is not an interval object

Passing an invalid value (e.g., a number, string) to deleteInterval.

fix

Ensure you pass the exact object returned by createInterval (or createIntervalSecond, etc.).
