Numbat - Example of verifying clients connecting on websockets

numbat-collector.config.js

var url = require('url');

// our secret which each client will verify against
const SECRET = 'foobar';

module.exports =
{
    logging:
    {
        name: 'numbat-1',
        silent: false
    },
    listen: { host: 'localhost', port: 3333, ws: true, verifyClient: function(info, cb) {
        // parse the url and get the key query value
        var uri = url.parse(info.req.url, true);
        if (uri.query.key === SECRET) {
            // key equals our secret, grant client access
            cb(true); 
        } else {
            // key does not equal our secret, deny access with a reason
            cb(false, 403, 'access denied');
        }
        
    } },
    outputs:
    [
        { type: 'prettylog', name: 'foobar' }
    ]
};

numbat-emitter.js

var Emitter = require('numbat-emitter');

// connect to the collector with a key and a legal secret value
var emitter = new Emitter({
	uri: 'ws://localhost:3333/?key=foobar',
	app: 'example-1'
});
