# loadbalancer
A simple threaded and clustered load balancer for nodejs with different forwarding algorithms and server request handling options.
## DEMOS
Find the demos in the [demo folder](https://github.com/ganeshkbhat/loadbalancer/tree/main/demos)
## FEATURES
The following features are inbuilt into the loadbalancer:
- [] Main Features
- [] Multi Processing and Multi Threading with Algorithm based routing
- [] Detailed Support based on development
- [] Loadbalanced Server (Multi Protocol Support)
- [] Loadbalanced Client (Multi Protocol Support)
## .loadbalancer module
There are six modules in the loadbalancer module: `loadbalancer`, `clustering`, `processingMultiple`, `processing`, `threadingMultiple`, `threading`
## .loadbalancer module
`.loadbalancer`
```
var loadbalancer = require("loadbalancerjs").loadbalancer;
var httpSocketServer = require("loadbalancerjs").sockets.httpSocketServer;
var server = require("./express-app");

"createCerts": true,
"host": "localhost",
"proxy": {
"proxy": true,
