## README

## lb-promisify

`lb-promisify` is the Loopback addon which adds promises to PersistedModel methods by default, but can be extended.

## 1. Installation

````sh
npm install lb-promisify --save
````

## 2. Configuration

server/server.js.json

    ...

    var promisify = require('lb-promisify')

    ...

    boot(app, __dirname);
    promisify(app);

    ...

## 3. Basic use



    var User = app.models.User,
        Post = app.models.Post;

    User
        .findById('user-id')
        .then(function(user) {
            return Post.find({ where: { authorId: user.id }});
        })
        .then(function(posts) {
            // do something with posts
        })
        .catch(function(err) {
            console.log(err);
        });

## 4. Advanced use

You can promisify more methods by add definitions. Before:

    promisify(app);

you can add something like this

    promisify.add('isValid',
        true,
        function (deferred) {
            return function (valid) {
                if(valid) {
                    deferred.resolve();
                }
                else {
                    deferred.reject();
                }
            }
        });
