trailpack-mongoose

📦 Mongoose.js Trailpack http://mongoosejs.com

Loads Application Models (in api/models) into the Mongoose ORM; Integrates with trailpack-router to generate Footprints for routes.

Usage

Include trailpack in app.

// config/main.js
module.exports = {
  // ...
  packs: [
    require('trailpack-mongoose')
  ]
}

Configure stores.

// config/database.js
module.exports = {

  /**
   * Define the database stores. A store is typically a single database.
   *
   * Use the SQLite3 by default for development purposes.
   *
   * Set production connection info in config/env/production.js
   */
  stores: {

    /**
     * Define a store called "local" which uses SQLite3 to persist data.
     */
    someteststore: {
      //migration
      migrate: 'create',
      // Mongodb URI
      uri: 'mongodb://localhost:27017/test',
      // Mongoose connection options
      options: {

      }
    }
  },

  models: {
    defaultStore: 'someteststore',
    migrate: 'drop'
  }
}
