Async Proxy for Posnet Server

This is simple multi-threading node.js queue implementation to asynchronously process fiscal printouts. https://blog.bigdotsoftware.pl/posnet-server-pierwsze-uzycie/

Overview

This service listen on port 3060 and forward requests (/paragon, /command and /faktura) into PosnetServer. Full information about available RESTpoints can be listed by executing http://localhost:3060/

Implemented queue:

• is not persisted - requests in the queue won't survive service restart
• has no threshold nor safety switch
• every single request is executed in separate thread. Once finished, thread is dispatched (When you have 100 "in progress" requests, mean service executed 100 threads)

Installation

This service has to be installed via npm:

git clone https://github.com/bigdotsoftware/posnetserver-async-proxy.git
cd posnetserver-async-proxy
npm install
