A redis client with pooled connections and promises.
- Virtually no tests.
npm install pooldis
var Pooldis = require("pooldis");
var redis = new Pooldis(); // more on that below...
redis.get("some:key").then(callback, errorHandler) // .then() ... and so on.var Pooldis = function(url, options) { /*...*/ }Either pass a valid redis url string, an options object or both.
In the form of redis://user:password@hostname:port (user:password and port are not required)
options.hostname(String) - represents the redis server hostname to connect to.options.port(Number) - represents the redis server port to connect to.options.password(String) - if auth is required.
Any other options usually accepted by node_redis will be passed along.
Any of these in options.pool will be passed along to node-pool.
options.pool.max(Number) - maximum number of acquirable connections.options.pool.min(Number) - minimum number of connections to hold.options.pool.idleTimeoutMillis(Number) - time in milliseconds before releasing a idle connection
Executing redis commands uses the same syntax as node_redis.
Dis uses Q as its promises implementation. Here's how it works:
var redis = new Pooldis()
redis.get("some:key")
.then(function(value){
// Do something with `value`
}, function(error){
// An error occurred. Handle it!
});Due to the blocking nature operations (BRPOP, BLPOP, BRPOPLPUSH), it's best to have a connection pool at our disposal to perform other commands while waiting.
For fun (and legibility).
