Plugin for easy rendering of Mongoose async Query results.
Adds Mongoose Query and Promise support to Express.
Methods which now support
Promises:
res.render
res.send
res.redirect
Methods which now support
Queries:
res.render
res.send
$ npm install express-mongoose
Include
express-mongoosein your project, which performs the necessary bindings between
expressand
mongoose.
require('express-mongoose') // thats it!
In your schemas:
UserSchema.methods.getLikes = function (callback) { // returns a Query return this.model('Likes').find({ _user: this._id }, callback); };NewsSchema.statics.getLatest = function (callback) { var promise = new Promise; if (callback) promise.addBack(callback); this.find({ datePublished: { $gt: new Date(Date.now() - 60000*60) } }, promise.resolve.bind(promise)); return promise; };
In your routes:
app.get('/dashboard', function (req, res) { var News = db.model('News');// render support res.render('dashboard', { likes: req.user.getLikes() , latestNews: News.getLatest() , stuff: new Promise(somethingAsync) }); });
With
res.sendsupport you can pass a
Queryor
Promiseand the result will be rendered as json. If an error occurs, the error will be passed to
next()as expected.
app.get('/send', function (req, res) { var News = db.model('News'); res.send(News.getLatest()); });app.get('/promises', function (req, res) { var promise = new Promise(somethingAsync); res.send(promise); });
app.get('/more', function (req, res) { res.send({ promise: new Promise(somethingAsync) , news: req.user.getLatest() }); });
res.redirectaccepts a
Promiseas well.
app.get('/redirect', function (req, res) { var promise = new Promise; res.redirect(promise);process.nextTick(function () { promise.complete(url [, status]); // or promise.error(new Error('uh oh')); }); });
If a
Queryor
Promiseresolves to an error it will be forwarded on with
next(err)as expected.
