    Providing a standard Store Interface and Redis-like API that you can use in wherever.

    Chinese version


    Loading via script tag:

    <script style="text/javascript" src="/path/to/script/min.js">

    With node previously installed:

    $ npm install min

    Basic Usage

    Common key-value via such as SET, GET, etc.

    min.set('foo', 'bar')
      .then(() => min.get('foo'))
      .then(value => console.log(value)) //=> bar
      .catch(err => console.error(err))

    Basic commands

    • set Set the value of a key (key, value)
    • setnx Set the value of a key, only if the key does not exist (key, value)
    • setex Set the value and expiration of a key (key, seconds, value)
    • psetex Set the value and expiration in milliseconds of a key (key, millseconds, value)
    • mset Set multiple keys to multiple values (plainObject)
    • msetnx Set multiple keys to multiple values, only if none of the keys exist (plainObject)
    • append Append a value to a key (key, value)
    • get Get the value of a key (key)
    • mget Get the values of a set of keys (keys)
    • getset Set the value of a key and return its old value (key, value)
    • strlen Get the length of a key (key)
    • incr Increment the integer value of a key by one (key)
    • incrby Increment the integer value of a key by the given amount (key, increment)
    • incrbyfloat Increment the float value of a key by the given amount (key, increment)

    Hash, List, Set, Sorted Set

    Maybe you can get the way by browsing Redis Commands. XD


    Anymore else? How about MULTI?

      .then(results => console.log(results)) //=> [ [ 1 ], [ 2 ], [ 3 ] ]
      .catch(err => console.error(err))

    SWEET! Let's run to Harmony(ES2015)!

    async _ => {
      var userId = await min.incr('users:id:seq')
      await min.hmset(`user:${userId}`, {
        name: 'Will Wen Gunn',
        sign: 'iwillwen',
        homepage: ''
      await min.sadd(`user:${userId}:msgs`, 'Welcome')

    Support multiple databases:

    var Min = min.fork()
    Min.set('foo', 'bar')
