node.js - Error: failed to connect to [127.0.0.1:27017] at null using MongoDB -


i'm attempting run node application , keep receiving error. not sure start:

events.js:85       throw er; // unhandled 'error' event             ^ error: failed connect [127.0.0.1:27017]     @ null.<anonymous> (/users/dte/limetime-dev/node_modules/mongoose/node_modules/mongodb/lib/mongodb/connection/server.js:557:74)     @ emit (events.js:118:17)     @ null.<anonymous> (/users/dte/limetime-dev/node_modules/mongoose/node_modules/mongodb/lib/mongodb/connection/connection_pool.js:156:15)     @ emit (events.js:110:17)     @ socket.<anonymous> (/users/dte/limetime-dev/node_modules/mongoose/node_modules/mongodb/lib/mongodb/connection/connection.js:534:10)     @ socket.emit (events.js:107:17)     @ net.js:451:14     @ process._tickdomaincallback (node.js:381:11) 

the error means mongodb not running or running on different port. node app doesn't manage mongodb you. before running app make sure mongodb running on port 27017.
