expire-cache

library1.0.0jsnpmunverified

A simple JavaScript cache library that supports key-value storage with configurable expiration times and namespacing. Version 1.0.0 (stable, last updated 2017) is available via npm and Bower. It offers a concise API with function overloads for get/set/remove and namespace support, allowing hierarchical sub-caches with independent expiry. The library is lightweight and works in Node.js and browsers via script tag or AMD.

Code

Verified usage

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

expireCache

✓ const expireCache = require('expire-cache');

✗ import expireCache from 'expire-cache';

The package does not ship ESM; use CommonJS require(). If using bundlers that support ESM, a default import may fail.

expireCache

✓ const expireCache = require('expire-cache');

✗ const { expireCache } = require('expire-cache');

The module exports a single function, not an object with named exports.

expireCache (browser script)

✓ <script src="/pathTo/expire-cache/index.js"></script>

✗ const expireCache = require('expire-cache'); inside browser without bundler

For browser use, include via script tag; the library expects window.expireCache.

Demonstrates basic set/get with default and custom expiry, namespace usage, and removal.

const expireCache = require('expire-cache'); // Set with default 5s expiry expireCache('key1', 123); console.log(expireCache('key1')); // 123 // Set with custom 10s expiry expireCache.set('key2', 456, 10); console.log(expireCache.get('key2')); // 456 // Create namespace with 1s expiry const cache1 = expireCache.namespace('test', 1); cache1('key', 789); console.log(cache1('key')); // 789 // Remove key expireCache.remove('key1'); console.log(expireCache('key1')); // undefined

Debug

Known issues

gotchaThe expireCache() function can be called with no arguments to retrieve all data, but also as a getter with a key. Be careful not to confuse the two patterns.

fix

Use .get() and .set() for clarity.

affects: >=0.0.0

deprecatedThe package has not been updated since v1.0.0 (2017). It lacks modern features like ESM, TypeScript types, and promises.

fix

Consider alternatives like lru-cache or node-cache.

affects: >=1.0.0

gotcharemove() can accept multiple keys as separate arguments or as an array, but mixing both (e.g., .remove('key', ['key1','key2'])) may not work as expected in older versions.

fix

Use an array for multiple keys: .remove(['key1', 'key2']).

affects: >=0.0.0

gotchaThe default expire time is 5 seconds. If you set a value without expire, it may be removed after 5 seconds.

fix

Explicitly set a large expire value if you want persistent cache.

affects: >=0.0.0

Errors

Common errors & fixes

TypeError: expireCache is not a function

The package is not imported correctly or the script is not loaded.

fix

Ensure require('expire-cache') returns a function. In browser, check script src.

expireCache(...) is not a function after import

Using ES6 import on a CommonJS module.

fix

Use const expireCache = require('expire-cache') instead of import.

require is not defined

Running in a browser without a module bundler.

fix

Use the script tag method: <script src="node_modules/expire-cache/index.js"></script>
