samypesse / blini Goto Github PK

This is a feature supported by Mongoose.

Expected

For example for a schema like:

const postSchema = new Schema({
    author: Type.Ref('User')
});

The query

const currentUser = new User(...);

Post.find({
     author: currentUser
});

should correctly transform currentUser into currentUser._id.

Implementation

Type should have a method toQuery(value).

Implementation by mongoose is done in lib/cast.js

The example application should a fully runnable web-application.

Should Blini have a plugin API to extend models (for example to have plugins like mongoose-plugin-created or mongoose-plugin-modified.

Solution 1: Mixins

Plugins can be function retuning plain mixin:

function CreatedPlugin(options) {
   return {
       save() {
           ...
       }
   };
}

Plugins could be added as mixin:

class Post extends Model(postSchema) {
    mixins: [createdPlugin]
}

Mixins are no longer an advised solution for modern frameword (ex: React: Mixins Considered Harmful

Solution 2: Inheritance / Composition

function CreatedPlugin(Model) {
     class ExtendedModel extends Model {
           save() {

           }
     }

     return ExtendedModel;
}

And plugin can be use with an helper Model.withPlugins to chain the composition:

module.exports = Model.withPlugins([
     CreatedPlugin
]);
