	return {
		TestModel: connection.model('TestModel', require('./TestModel')(mongoose)),
	};
}

handlers/GET.js

module.exports = (req, reply, service) => {
	// access model class for connection "m1"
	const TestModel_C1 = service.dataConnections.m1.schema.TestModel;
	
	// access GridFs (gridfs-stream) for connection "m1"
	const GridFs_C1 = service.dataConnections.m1.gridfs;
	
	// access the mongoose connection object for connection "m1"
	const Connection_C1 = service.dataConnections.m1.connection;
	
	// access the mongoose object (shared between all connections)
	const mongoose = service.dataConnections.m1.mongoose;
	
	// get model class for connection "m2" 
	const TestModel_C2 = service.dataConnections.m2.schema.TestModel;
	...
}

index.js

'use strict';

const atrix = require('@trigo/atrix');
const path = require('path');

const svc = atrix.addService({
	name: 'mongoose', 
	endpoints: {
		http: {
			// declare port to bind
      port: 3007,

      // the directory containing the handler files
      handlerDir: `${__dirname}/handlers`,
   	},
  },
	// declare a dataSource config section
	dataSource: {
		// name of the data source
		m1: {
			// type of data connection
			type: 'mongoose',
			// connection configuration
			config: {
				// path to the model factory module to be required by the plugin
				modelFactory: path.join(__dirname, './models/factory'),
				
				// database connection string
				connectionString: 'localhost:27017/test-atrix-mongoose-m1',
			},
		},
		m2: {
			type: 'mongoose',
			config: {
				modelFactory: path.join(__dirname, './models/factory'),
				connectionString: 'localhost:27017/test-atrix-mongoose-m2',
			},
		},
	},
});

// start service. 
// This will wait for the mongo connection to be available before starting up. 
// When conection(s) is lost after initial startup the plugin automatically tries to reconnect  
svc.start();

Run service with node index.js

Common issues

If you installed mongoose itself and your code requires it somewhere before the plugin is loaded, you have a good chance to break connection & model setup. Do not install mongoose itself!. If unsure simply run npm remove -S mongoose in your application root folder.

Contributing

If you update a package (especially mongoose) or the node version than you should run specs/failed-connection.specs.sh to ensure that the return codes on failed MongoDb connections are still correct.
