node.js - How to increase connection timeout for Mongolab while connecting from loopback mongodb driver -

i have hosted mongodb in mongolab. have created odm in loopback , made connection mongolab. connection gets established other times due bad connection gets timedout. want increase timeout connected everytime. did not find solution on strongloop site.

i tried adding query string param in connection string mongolab: ?connecttimeoutms=1000000 did not help.

use connectiontimeout setting in datasources.json file.

{   "yourmongodb": {     "name": "yourmongodb",     "connector": "mongodb",     "connectiontimeout": 1000000   } }
