fanout/pushpin

@anton-christensen I am doing as whats in the express-grip doc, 'not implemented' is the error.Below is the express app code......const express = require('express');
const router = express.Router();
const grip = require('grip');
const expressGrip = require('express-grip');
router.use(expressGrip.preHandlerGripMiddleware);

// Pushpin and/or Fanout.io is used for sending realtime data to clients
const myConfigObject = {
gripProxyRequired: true,
gripProxies : [
// Pushpin
{
'control_uri': 'http://localhost:5561'
},
// Fanout.io
{

    }],

};

expressGrip.configure(myConfigObject);

router.get('/', function(req, res, next) {
try {
// If the request didn't come through a GRIP proxy, throw 501
if (!res.locals.gripProxied) {
res.sendStatus(501);
return;
}

    // Subscribe every incoming request to a channel in stream mode
    expressGrip.setHoldStream(res, 'channel');
    res.send('stream open\n');

    // Alternatively subscribe and long-poll
    //expressGrip.setHoldLongpoll(res, '<channel>', <timeout>);
    //res.end();
} finally {
    // next() must be called for the post-handler middleware to execute
    next();
}

});

router.post('/', function(req, res, next) {
var data = req.body;

// Publish stream data to subscribers
expressGrip.publish('channel', new grip.HttpStreamFormat(data + '\n'));

// Alternatively publish response data to long-poll clients
//expressGrip.publish('<channel>',
//        new grip.HttpResponseFormat(null, null, null, data));

res.send('Ok\n');
next();

});

// Add the post-handler middleware to the back of the stack
router.use(expressGrip.postHandlerGripMiddleware);

/** var pub = new grip.GripPubControl({
'control_uri': 'http://localhost:5561'
});

pub.publishHttpStream('channel', 'hello realtime mahn\n');

res.writeHead(200, {
    'Content-Type': 'text/plain',
    'Grip-Hold': 'stream',
    'Grip-Channel': 'channel'
});
res.end('Stream opened, prepare yourself!\n');

});**/

module.exports = router;
