library1.0.20jsnpmunverified

Lightweight in-memory key-value storage with TTL support for Erxes ecosystem. Version 1.0.20 is the current stable release. No recent updates; maintenance mode. Differentiators: simple API with set/get/remove methods and per-key TTL. Alternative is redis.

Code

Verified usage

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

default

✓ import InMemoryStorage from 'erxes-inmemory-storage'

✗ const InMemoryStorage = require('erxes-inmemory-storage').default

Default import is the main class.

InMemoryStorage

✓ import InMemoryStorage from 'erxes-inmemory-storage'

✗ import { InMemoryStorage } from 'erxes-inmemory-storage'

Named import not available; use default import.

MemoryStorage (type)

✓ import type { MemoryStorage } from 'erxes-inmemory-storage'

TypeScript type export; use as type.

Creates in-memory storage instance, sets a key with TTL, reads it, and removes it.

import InMemoryStorage from 'erxes-inmemory-storage'; const storage = new InMemoryStorage(); storage.set('key', 'value', 10000); // 10 second TTL const value = storage.get('key'); console.log(value); // 'value' storage.remove('key'); storage.clear();

Debug

Known issues

gotchaTTL is in milliseconds, not seconds. Using seconds will cause early expiration.

fix

Multiply seconds by 1000 when passing TTL.

affects: >=1.0.0

gotchaStorage is not persistent; data is lost on process restart.

fix

Use a persistent store (e.g., redis) if data must survive restarts.

affects: >=1.0.0

gotchaAll values are stored as strings internally. Objects/numbers are coerced to string.

fix

Explicitly serialize/deserialize non-string values (e.g., JSON.stringify/parse).

affects: >=1.0.0

deprecatedPackage is in maintenance mode. No new features or bug fixes planned.

fix

Consider migrating to a more maintained in-memory storage solution.

affects: >=1.0.20

Errors

Common errors & fixes

TypeError: InMemoryStorage is not a constructor

Using named import instead of default import.

fix

Use: import InMemoryStorage from 'erxes-inmemory-storage'

Value 'undefined' returned for key despite setting it with TTL

TTL in seconds instead of milliseconds causing immediate expiration.

fix

Ensure TTL is in milliseconds (e.g., 10000 for 10 seconds).

Cannot read properties of undefined (reading 'get')

Storage instance not initialized correctly.

fix

Make sure to call 'new InMemoryStorage()' before using methods.
