redis-pool

Redis connection pool with native promise support

Installation

$ npm install git+ssh://git@github.com/ahauser31/redis-pool.git

Usage

This library is based on node-redis and as such supports most of the libraries functions and can (almost) serve as a drop-in replacement. For specific commands, please see the node-redis project. Commands accept a callback (for compatability with libraries such as ratelimit) and will return a promise if no callback was provided. New connections will be established automatically when they are required; the user does not have to do anything.

Important note

Currently, testing was only done for standard functions (get, set, del, keys, etc.). multi is supported. Advanced functionality (subscribe, etc.) is not tested and unlikely to work. If you find that any function does not work, please let me know in the issues.

Example

var redis = require('redis-pool');

// create pool
var db = redis.createClient(); // Connects with redis on 127.0.0.1:6379

// write a value to redis and read it back
db.set('foo', 'bar').then( (res) => {
	console.log(res);
}).catch( (err) => {
	console.log('Error!');
	console.log(res);
});

db.get('foo', (err, res) => {
  if (err) {
	console.log('Error!');
	console.log(err);
  }
  
  console.log(res);
});

Example output

bar
