Question

Morning. I have recently started to get into the wonders of NODE.JS and have a node that extracts information from an Active MQ datafeed via stomp, and renders it using prettyjson and outputs to the console.

var prettyjson = require('prettyjson'),
    StompClient = require('stomp-client').StompClient;

var destination = '/topic/(topic)',
    client = new StompClient('datafeeds.(datafeedlocation)', 61618, '(email.address)', '(password)', '1.0');

client.connect(function(sessionId) {
    console.log('Trying to connect...');
    client.subscribe(destination, function(body, headers) {
        console.log(prettyjson.render(JSON.parse(body)));
    });
});

and the feed churns out quite happily on the console.

Now I have read a lot of examples, and most of them always output to the console.. however I want to take this data and do something with it.

So how do I take the console output and store it, or just skip the console output and just store in the information.. any method for now is fine, in a json file, or to a database.. hell.. even a text file. Good clear guides are fine, not expecting anyone to write code for me.

Thanks in advance for any good pointers.

Was it helpful?

Solution

Bah, as per usual after posting for help.. i get it working.. here is the final code

var prettyjson = require('prettyjson'),
    fs = require('fs'),
    StompClient = require('stomp-client').StompClient;

var destination = '/topic/(topic)',
    client = new StompClient('datafeeds.(datafeed)', 61618, '(email.address)', '(password)', '1.0');

client.connect(function(sessionId) {
    console.log('Trying to connect...');
    client.subscribe(destination, function(body, headers) {
        fs.writeFile("./output", prettyjson.render(JSON.parse(body)), function(err) {
    if(err) {
        console.log(err);
    } else {
        console.log("The file was saved!");
    }
}); 
    });
});
