ioredis-mock

• Fixed: keys no longer returns empty sets, just like real redis (#358)

• Fixed: srandom not using Set. (#356 @ianmuninio)

• Fixed: DEL should return number of keys deleted from the data, not the number of arguments (#355 @donaldjarmstrong)

• Fixed: Passing null values should not throw exceptions (#353 @kkragenbrink)

Added

ZRANGEBYSCORE command (#350 @usebaz)

const data = {
  foo: new Map([
    ['first', { score: 1, value: 'first' }],
    ['second', { score: 2, value: 'second' }],
    ['third', { score: 3, value: 'third' }],
    ['fourth', { score: 4, value: 'fourth' }],
    ['fifth', { score: 5, value: 'fifth' }],
  ]),
};
const RedisMock = require('ioredis-mock');
const redis = new RedisMock({ data });
redis
  .zrangebyscore('foo', 1, 3)
  .then(result => console.log(result)) // logs ['first', 'second', 'third']

QUIT stub (#350 @usebaz)

In ioredis this is the equivalent to calling redis.disconnect. ioredis-mock does not implement connection simulation functionality yet so for now it's just a stub.

redis.quit() // OK

UNSUBSCRIBE stub (#350 @usebaz)

Our previous release added subscribe and joining the fray you can now pretend to be unsubscribing (just like the newsletters in your inbox!)

redis.unsubscribe() // OK

Added

Subscribe Stub (#348 @yitongding)

const RedisMock = require('ioredis-mock');
const redis = new RedisMock();
redis.subscribe('news', 'music').then(result => console.log(result)) // logs '2'

• Fixed: Remove .eslintcache file from package (#347)

• Fixed: More detailed RunKit example (#346)

Added

Full Argument and Reply transformer support (#342 @DrMegavolt)

Any transformer you use on arguments and replies in ioredis will work in ioredis-mock 🎉

Since we're now able to load the built in transformers in ioredis we could finally get rid of old code related to the the hgetall and hmset commands.

If you're using ioredis-mock standalone and haven't upgraded to v3.3.0 or newer

The following only apply if you use ioredis-mock without installing ioredis

If this is your use case you'll need to install ioredis as well or ioredis-mock will not work as we're using ioredis internals to stay compatible. Using ioredis-mock without installing ioredis have been possible up to now but's newer actually been officially supported. That's why ioredis have always been specified as a peerDependency.

• Fixed: Missing runkit file (#340)

Added

Added support for passing Map and Object to hmset

This is a stopgap solution until real argument and reply transformers is implemented and fully compatible with ioredis

ZADD command (#321 @ddunkin)

redis.zadd('myzset', '1', 'one', '1', 'uno',  '2', 'two', '3', 'three') // returns `4` as 4 items got added

ZRANGE command (#321 @ddunkin)

redis.zrange('myzset', 0, -1) // ['one', 'uno', 'two', 'three']

ZREVRANGE command (#321 @ddunkin)

redis.zrevrange('myzset', 0, -1) // ['three', 'two', 'uno', 'one']

ZREMRANGEBYRANK command (#321 @ddunkin)

redis.zremrangebyrank('myzset', 0, 2) // returns '3' as that’s how many items got deleted
redis.zrange('myzset', 0, -1) // ['three']

New Commands

SCAN command (#334 @DrMegavolt)

redis
  .scan(0, 'MATCH', 'foo*', 'COUNT', 1)
  .then(result => console.log(result))

LRANGE command (#335 @sseidametov)

redis
  .lrange('myKey', 0, 2)
  .then(result => console.log(result))

• Fixed: Errors in smembers and srem when no data is set (#332)

• Fixed: Fixed hexists edge cases (#331)

• Fixed: Ignore codeclimate

New features

Add pipelining with method chaining (#312 @funnisimo)

Added a 'pipeline' method which allows chaining of methods like ioredis.

Updated discard and multi to work with the pipeline.

• Fixed: Add back support for node v0.10.x like ioredis (#327)

• Fixed: remove README and RunKit references to old import style

Breaking changes

Use module.exports to be in line with ioredis (#311 @rexxars)

ioredis uses commonjs exports, and now ioredis-mock does as well.

require('ioredis-mock').default no longer works, use require('ioredis-mock') instead.

Bug fixes

Error thrown in sismember() if key does not exist (#318 @theogravity)

• Fixed: Allow ioredis 3 as peer dependency (#317 @aruberto)
