Muri is your friendly neighborhood MongoDB URI parser for Node.js.

$ npm install muri

 var muri = require('muri');
 var o = muri('mongodb://user:pass@local,remote:27018,japan:27019/neatdb?replicaSet=myreplset&journal=true&w=2&wtimeoutMS=50');

 console.log(o);

 { hosts: [ { host: 'local',  port: 27017 },
            { host: 'remote', port: 27018 },
            { host: 'japan',  port: 27019 } ],
   db: 'neatdb',
   options: {
     replicaSet: 'myreplset',
     journal: true,
     w: 2,
     wtimeoutMS: 50
   },
   auth: {
     user: 'user',
     pass: 'pass'
   }
 }

The returned object contains the following properties:

• db: the name of the database. defaults to "admin" if not specified
• auth: if auth is specified, this object will exist { user: 'username', pass: 'password' }
• hosts: array of host/port objects, one for each specified [{ host: 'local', port: 27107 }, { host: '..', port: port }]
  • if a port is not specified for a given host, the default port (27017) is used
  • if a unix domain socket is passed, host/port will be undefined and ipc will be set to the value specified [{ ipc: '/tmp/mongodb-27017' }]
• options: this is a hash of all options specified in the querystring
