redis-hash-js

This module provides RedisHash, a class that adds some basic syntactic sugar around Redis hash commands like HMGET, HMSET, HINCRBY, among others. Supported operations include:

• Bulk setting and getting
• Boolean flags
• Counters

Example

redis = require('redis');
RedisHash = require('redis-hash-js');

hash = new RedisHash(redis.createClient(), 'hashKey');

hash.set('x', 'y');
hash.get('x', function(err, result) {
  console.log("x is " + result);
});

hash.set({
  a: '1',
  b: '2'
});

hash.get(function(err, result) {
  for (k in result) {
    console.log(k + ": " + result[k]);
  }
});
