mongoose-express-router

Create Express 4 router and middleware from Mongoose 4 model.

Usage

var express = require('express');
var mongoose = require('mongoose');
var router = require('mongoose-express-router');

var db = mongoose.createConnection('mongodb://localhost/test');
var schema = mongoose.Schema({ name: 'string' }).plugin(router);
var User = mongoose.model('User', schema);

var app = express();
app.use('/users', User.router());

app.listen(3000);

You can also use router middleware individually:

app
  .get('/users', User.router('find'))
  .post('/users', User.router('create'))
  .get('/users/:id', User.router('findOne'))
  .patch('/users/:id', User.router('update'))
  .delete('/users/:id', User.router('delete'));

Queries

The following query parameters are recognized:

• skip or offset
• limit
• sort
• select
• populate
• match

Session handling

It's often useful to have the session available in mongoose middleware to do things like validation and authorization.

Accessing the session from query or model middleware

User.pre('find', function (next) {
  console.log(this.session);
  next();
});

User.pre('save', function (next) {
  console.log(this.session);
  next();
});

Setting the session

The session is set whenever the router middleware is used, otherwise set the session query option.

User.findOne()
  .setOptions({ session: req.session })
  .exec(function (err, user) {
    console.log(user.session === req.session);
    // => true
  });

Body parsing

You must provide your own body parsing middleware. A req.body object must be available for the post/create middleware to work.

Custom middleware

Custom middleware can be accessed using Model.router() and has the model exposed via req.Model:

schema.plugin(router, {
  middleware: {
    myMiddleware: function (req, res, next) {
      console.log(req.Model);
      next();
    }
  }
});

// Returns middleware
User.router('myMiddleware');
