balancier

Balancier

It's got a french name.

Balancier is a round robin load balancer middleware for node-http-proxy. I did not build this with it being intended for use in production. I built this for a project that did not require WebSockets, so it doesn't support WebSockets per http-proxy's needs.

Example

var httpProxy = require('http-proxy'),
    balancier = require('balancier');
 
/**
 *	Give the proxy something to start with
 */
balancier.add([
    {
        host: '127.0.0.1',
        port: 3000
    },
    {
        host: '127.0.0.1',
        port: 3001
    }
]);
 
/**
 *	Create our proxy
 *	Pass in our middleware for balancier
 */
var server = httpProxy.createServer(balancier.middleware, options);
 
server.listen(8000);
 

Adding and removing servers

/**
 *	Add servers
 *	You can pass in one server or an array of servers
 *	Servers will not be added unless they has a `host` and a `port`
 */
var result = balancier.add({
    host: '127.0.0.1',
    port: 3002
});
 
console.log(result); // true if the server was removed successfully
 
/**
 *	Remove servers
 */
balancier.remove({
    host: '127.0.0.1',
    port: 3002
});
 
console.log(result); // true if the server was removed successfully
 
/**
 *	See all servers
 */
var servers = balancier.getBackends();
console.log(servers); // [ { server1 }, { serverN } ]
