gtfs.getStops() throws Mongoose DeprecationWarning

[Kenny806]

Hi, I tried creating a simple example that would download my local agency's timetables and just print the available stops to console. I set mongoose.promise in my code, but still get a warning when I call gtfs.getStops(). My code is:

const config = require('./config.json');
const gtfs = require('gtfs');
var mongo = require('mongodb');
var mongoose = require('mongoose');

mongoose.Promise = global.Promise;

mongoose.connect(config.mongoUrl, {useMongoClient: true}).then(function() {
    console.log('connected')
    gtfs.getStops({
        agency_key: 'dpp'
    })
    .then(stops => {
        console.log(stops);
    });
}).catch(err => console.log(err));

config.json:

{
  "mongoUrl": "mongodb://localhost:27017/gtfs",
  "agencies": [
    {
      "agency_key": "dpp",
      "url": "http://opendata.iprpraha.cz/DPP/JR/jrdata.zip"
    }
  ]
}

I am using mongoose 4.11.8 and I ran gtfs.import and it reported no errors, and I did not find any problems in the db either. I found this issue on mongoose github and it seems there is a workaround, but it would require inserting
mongoose.promise = global.Promise
into almost every file that accesses the db, including gtfs files. Have you encountered this issue before or do you have any more feasible workaround?

Thanks

This happens when your project has mongoose installed twice - once as a dependency of your project and once as a dependency of node-gtfs. Is mongoose specified as a dependency of your project in package.json or is it installed globally?

Thanks, that helped!

It was specified as a dependency in my package.json. I removed it, reinstalled node_modules and now it works fine.

The only slight issue is, that when I want to access mongoose in my project, I have to require the one installed as a dependency of node-gtfs. Like this:
const mongoose = require('./node_modules/gtfs/node_modules/mongoose');
Is there a nicer way to do that?

It is ok to specify it as a dependency in your project as long as you specify the exact same version as node-GTFS and don’t use ^ or ~ in front of it. Then, delete node_modules and npm install. NPM should realize that it only needs to install one copy of mongoose.
