library1.3.1jsnpmunverified

feather-cache v1.3.1 is a lightweight pluggable key-value cache supporting multiple storage backends (in-memory, MongoDB, IndexedDB). Released under MIT license with low release cadence (last update ~2019). It differentiates from simpler caches like lru-cache by allowing custom drivers for persistent storage. Built-in TypeScript types. The in-memory driver is for convenience; for serious in-memory caching, lru-cache is recommended. Supports async get/set/delete with optional TTL per key.

Code

Verified usage

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

FeatherCache

✓ import { FeatherCache } from 'feather-cache'

✗ import FeatherCache from 'feather-cache'

FeatherCache is a named export, not default.

FeatherCache

✓ const { FeatherCache } = require('feather-cache')

✗ const FeatherCache = require('feather-cache')

CommonJS require must destructure the named export.

FeatherCacheOptions

✓ import type { FeatherCacheOptions } from 'feather-cache'

✗ import { FeatherCacheOptions } from 'feather-cache'

FeatherCacheOptions is a type; use type import in TypeScript.

Demonstrates in-memory cache with set, get, fetch, and delete operations.

import { FeatherCache } from 'feather-cache'; const cache = new FeatherCache({ maxAgeInMs: 60000 }); async function main() { await cache.set('greeting', 'Hello, World!'); const value = await cache.get('greeting'); console.log(value); // 'Hello, World!' const result = await cache.fetch('greeting'); console.log(result); // { key: 'greeting', val: 'Hello, World!' } await cache.del('greeting'); console.log(await cache.get('greeting')); // null } main().catch(console.error);

Debug

Known issues

gotchaIn-memory cache is for convenience only; not designed for high-performance in-memory caching.

fix

Use lru-cache if you need a robust in-memory cache.

affects: >=1.0.0

deprecatedThe library has not been updated since 2019; may have compatibility issues with newer Node versions.

fix

Consider alternatives like lru-cache instead.

affects: >=1.3.0

breakingThe `fetch` method returns an object { key, val } instead of just the value.

fix

Use `cache.get(key)` if you only need the value.

affects: >=1.0.0

Errors

TypeError: FeatherCache is not a constructor

Using default import instead of named import.

fix

Change to: import { FeatherCache } from 'feather-cache'

Cannot find module 'feather-cache' or its corresponding type declarations.

TypeScript strict mode without proper import syntax.

fix

Ensure you are using: import { FeatherCache } from 'feather-cache'
