ewd-qoper8-express

This module may be used to integrate Express with ewd-qoper8, for simpler routing and handling of incoming HTTP requests within ewd-qoper8's master and worker processes.

Installing

npm install ewd-qoper8-express

Getting Started

server.js

'use strict';

var express = require('express');
var bodyParser = require('body-parser');
var qoper8 = require('ewd-qoper8');
var qx = require('ewd-qoper8-express');

var app = express();
app.use(bodyParser.json());

var q = new qoper8.masterProcess();
qx.addTo(q);

app.post('/qoper8', function (req, res) {
  qx.handleMessage(req, res);
});

app.get('/qoper8/test', function (req, res) {
  qx.handleMessage(req, res);
});

q.on('started', function () {
  this.worker.module = process.cwd() + '/worker-module';
  app.listen(8080);
});

q.start();

worker-module.js

'use strict';

module.exports = function () {

  this.on('message', function (messageObj, send, finished) {
    var results = {
      youSent: messageObj,
      workerSent: 'hello from worker ' + process.pid,
      time: new Date().toString()
    };
    finished(results);
  });

};
