Mixins

Source Code

Loopback Mixins are defined as a function within your mixins folder (my-mixin.js):

  module.exports = function(model, options){
    // do your magic
  }

Loading

To make the Mixins available to the models one has to either add the source dir (or the files) to the _meta section of the model-config.json:

{
  "_meta": {
    "mixins": [
      "loopback/server/mixins",
      "../mixindir/relative/to/the/appRootDir",
      "@joinbox/thingy/mixins/whuat"
    ]
  }
}

Configuration

To hook in your mixin to a model, you can add it to the model's mixin section of the definition file (your-model.json:

{
    "name": "YourModel",
    "mixins": {
       "MyMixin": {
         "optionValue": true
       }
    }
}

Note: You don't have to specify options, you can just set the value of "MyMixin" to true.
