command-queue-module

library1.0.0jsnpmunverified

A lightweight utility (v1.0.0, stable) for creating proxy modules that queue method calls before the actual module is loaded. Unlike heavier alternatives like lazy-async (20x larger), it focuses on minimal size and a simple API. The proxy mirrors the original API exactly; queued commands replay in order once the real implementation arrives. Ideal for deferring non-critical libraries (e.g., analytics) while still collecting calls early.

Code

Verified usage

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

createCommandQueueModule

✓ import createCommandQueueModule from 'command-queue-module'

✗ const { createCommandQueueModule } = require('command-queue-module')

Default export only; named destructuring from require() returns undefined.

createCommandQueueModule

✓ const createCommandQueueModule = require('command-queue-module')

✗ const { createCommandQueueModule } = require('command-queue-module')

CommonJS: use default assignment, not destructuring.

createCommandQueueModule

✓ import createCommandQueueModule from 'command-queue-module'

✗ import { createCommandQueueModule } from 'command-queue-module'

ESM: default import, not named import.

Creates a proxy for a module with two methods; calls are queued and replayed once the real module loads after 1 second.

import createCommandQueueModule from 'command-queue-module'; const api = createCommandQueueModule(['log', 'error'], (onLoad) => { const realModule = { log: (msg) => console.log('LOG:', msg), error: (msg) => console.error('ERROR:', msg), }; setTimeout(() => onLoad(realModule), 1000); }); api.log('queued call'); api.error('queued error'); // After 1 second, both calls are invoked on realModule.

Known issues

deprecatedThe package is no longer maintained; consider using a more modern alternative or native dynamic imports.

fix

Switch to lazy-async or implement your own queue with ES6 Proxies.

affects: >=1.0.0

gotchaMethod names must be passed as strings; the proxy only exposes these methods. Unknown properties will return undefined.

fix

Ensure all needed method names are listed in the array.

affects: >=0.0.0

gotchaThe loadCallback is invoked synchronously; if onLoad is never called, queued commands are lost.

fix

Always call onLoad with the real module; handle errors to prevent orphans.

affects: >=0.0.0

Errors

Common errors & fixes

TypeError: createCommandQueueModule is not a function

Using named import instead of default import in ESM.

fix

Use `import createCommandQueueModule from 'command-queue-module'`

Cannot read property 'trackEvent' of undefined

Required as object destructuring in CommonJS.

fix

Use `const createCommandQueueModule = require('command-queue-module')`
