Create a Mongoose ORM wrapped service for FeathersJS.

This Feathers service adapter is the same as the feathers-mongoose adapter, but includes optimizations for handling bulk insertion of data. With the current feathers-mongoose adapter, when you pass 100 items to create and 1 or more have errors either with validation or write errors (duplicate _id) you will only get back the first error and this will throw and skip any after hooks. This plugin returns a success response when a record is inserted, but pushes errored records into params.errors[]. You can handle those in an after hook at hook.params.errors. Even with errors, the after hooks will be run as all the items with errors will be present in params.errors[].

This adapter drops support for Node.js V4.

Installation

npm install feathers-mongoose-advanced --save

Getting Started

Creating an Mongoose service is this simple (make sure your MongoDB server is up and running):

var mongoose = require('mongoose');
var MongooseModel = require('./models/mymodel')
var mongooseService = require('feathers-mongoose-advanced');
 
mongoose.Promise = global.Promise;
mongoose.connect('mongodb://localhost:27017/feathers');
 
app.use('/todos', mongooseService({
  Model: MongooseModel
}));

See the Mongoose Guide for more information on defining your model.

Complete Example

Here's a complete example of a Feathers server with a message mongoose-service.

const feathers = require('feathers');
const rest = require('feathers-rest');
const socketio = require('feathers-socketio');
const errors = require('feathers-errors');
const bodyParser = require('body-parser');
const mongoose = require('mongoose');
const service = require('feathers-mongoose-advanced');
 
// Require your models
const Message = require('./models/message');
 
// Tell mongoose to use native promises
// See http://mongoosejs.com/docs/promises.html
mongoose.Promise = global.Promise;
 
// Connect to your MongoDB instance(s)
mongoose.connect('mongodb://localhost:27017/feathers');
 
 
// Create a feathers instance.
const app = feathers()
  // Enable Socket.io
  .configure(socketio())
  // Enable REST services
  .configure(rest())
  // Turn on JSON parser for REST services
  .use(bodyParser.json())
  // Turn on URL-encoded parser for REST services
  .use(bodyParser.urlencoded({extended: true}));
 
// Connect to the db, create and register a Feathers service.
app.use('messages', service({,
  Model: Message,
  paginate: {
    default: 2,
    max: 4
  }
}));
 
// A basic error handler, just like Express
app.use(errors.handler());
 
app.listen(3030);
console.log('Feathers Message mongoose service running on 127.0.0.1:3030');

You can run this example by using npm start and going to localhost:3030/messages. You should see an empty array. That's because you don't have any messages yet but you now have full CRUD for your new message service, including mongoose validations!
