node-redis-mock

library0.2.16jsnpmunverified

Node-redis-mock is a minimal mock implementation of the popular node_redis client for unit testing code that depends on Redis operations. Version 0.2.16 is the latest stable release, with last publish in 2015. It simulates Redis commands in-memory without requiring a running Redis instance. Key differentiators include support for a subset of Redis commands covering strings, hashes, lists, keys, pub/sub, transactions, and server commands. However, it lacks many modern ioredis features and is unmaintained, making it suitable only for legacy projects using node_redis. Release cadence is irregular; no updates in years.

Install & Compatibility

No compatibility data collected yet for this library.

Code

Verified usage

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

redis

✓ var redis = require('node-redis-mock');

✗ import redis from 'node-redis-mock';

This package uses CommonJS; ESM import may fail. No TypeScript types.

createClient

✓ var client = redis.createClient();

✗ var client = new redis.createClient();

createClient is a factory function, not a constructor.

redis (with destructuring)

✓ var { createClient } = require('node-redis-mock');

✗ var { createClient } = require('redis-mock');

Common package name confusion with 'redis-mock'.

Shows basic set/get operations using callback style with node-redis-mock.

var redis = require('node-redis-mock'); var client = redis.createClient(); client.set('foo', 'bar', function(err, reply) { if (err) throw err; console.log(reply); // OK client.get('foo', function(err, value) { console.log(value); // bar client.quit(); }); });

Debug

Known issues

deprecatedPackage is unmaintained since 2015 and may not work with newer Node versions (>=12).

fix

Migrate to a maintained mock like redis-mock (newer fork) or ioredis-mock.

affects: >=0.2.16

gotchaMany Redis commands are not implemented: e.g., SORT, SCAN, GEO, etc. Tests may pass unexpectedly.

fix

Check the implemented commands list and add mocks for missing ones, or switch to a more complete mock.

affects: >=0.2.0

breakingdbsize() always returns 0, not the actual key count.

fix

Do not rely on dbsize for accurate key counts in tests.

affects: >=0.2.0

gotchaThe package name is similar to 'redis-mock' and 'ioredis-mock', causing confusion. Installed package may be wrong.

fix

Ensure npm install node-redis-mock yields the correct package.

affects: >=0.2.0

Errors

Common errors & fixes

Error: Cannot find module 'node-redis-mock'

Package not installed or name mistyped.

fix

Run 'npm install node-redis-mock' and verify package.json.

TypeError: redis.createClient is not a function

Default import used with ESM or incorrect require statement.

fix

Use CommonJS require: var redis = require('node-redis-mock');

Redis command 'SET' not implemented

Command not supported by this mock.

fix

Add a manual stub or switch to a mock with broader command support.

Timeout: client did not emit 'ready' within 5000ms

Mock client might not emit 'ready' in all usage patterns.

fix

Call client.emit('ready') manually or ensure client.connect() is called if mock supports it.
