typeorm-in-memory-cache

library1.0.2jsnpmunverified

Provides an in-memory cache provider for TypeORM, wrapping node-cache. Version 1.0.2 is the latest stable release. This package is a thin wrapper around node-cache, offering simplicity and minimal configuration. It is suitable for development or single-process applications, but lacks distributed cache features found in alternatives like ioredis or redis. No significant release cadence; appears unmaintained since 2020.

Verified usage

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

InMemoryCacheProvider

✓ import InMemoryCacheProvider from 'typeorm-in-memory-cache'

✗ const InMemoryCacheProvider = require('typeorm-in-memory-cache')

Default export; CJS require works but TypeScript may prefer ESM import with default.

InMemoryCacheProvider

✓ import { InMemoryCacheProvider } from 'typeorm-in-memory-cache'

✗ import { InMemoryCacheProvider } from 'typeorm-in-memory-cache'

Named import also works as the package has a named export alias, but default is more common.

NodeCache

✓ import NodeCache from 'node-cache'

✗ const NodeCache = require('node-cache');

If customizing node-cache options, import NodeCache separately. The wrapper accepts an optional NodeCache instance.

Shows how to configure TypeORM to use the in-memory cache provider with a default node-cache instance.

import InMemoryCacheProvider from 'typeorm-in-memory-cache'; import { DataSource } from 'typeorm'; const AppDataSource = new DataSource({ type: 'sqlite', database: ':memory:', entities: [], synchronize: true, cache: { duration: 60000, provider() { return new InMemoryCacheProvider(); } } }); AppDataSource.initialize().then(() => { console.log('Data Source has been initialized!'); }).catch((err) => { console.error('Error during Data Source initialization', err); });

Debug

Known issues

gotchaThe cache is in-memory and not shared across processes/instances. For clustered or multi-process applications, use a distributed cache like Redis.

fix

Consider using typeorm's Redis or ioredis cache provider for distributed setups.

affects: >=0.0.0

gotchaThe package is a thin wrapper around node-cache; node-cache is not included as a dependency but as a peer dependency? Actually, node-cache is a transitive dependency of typeorm-in-memory-cache, but ensure node-cache is installed.

fix

Run npm install node-cache if you encounter errors.

affects: >=0.0.0

deprecatedThe package has not been updated since 2020 and may not be compatible with future TypeORM versions. TypeORM 0.3.x introduced breaking changes in cache API.

fix

Check TypeORM version compatibility; use with TypeORM 0.2.x only. For 0.3.x, consider using TypeORM's built-in caching or another cache provider.

affects: >=1.0.0

Errors

Common errors & fixes

ERR_REQUIRE_ESM: require() of ES Module not supported

Using CommonJS require() when package is ESM-only or has default export that is an ES module.

fix

Use import statement or set type: 'module' in package.json.

TypeError: InMemoryCacheProvider is not a constructor

Possibly due to incorrect import (e.g., importing named export when only default exists) or module resolution issue.

fix

Ensure import statement is correct: import InMemoryCacheProvider from 'typeorm-in-memory-cache';

Cannot find module 'node-cache'

node-cache is a dependency of typeorm-in-memory-cache, but may not be installed if npm did not resolve automatically.

fix

Run npm install node-cache to explicitly install it.
