Database Usage

Back to Documentation main page

Directly accessing built in databases engine from inside a service

This framework provides a commom API to access it available storage engine service clients.

The store API is built over the Application instance.

Putting in practice

Actually we provide support to 2 storage engines: Sequelize and Mongoose

Accessing Mongoose models from inside a service layer

Lets suppose you need to handle the DemoUser collection from mongoose from inside a service layer method.

All you need is to directly call the model object from application.$models.mongoose API. Example:

Mongoose API object at application.$models API

this.application.$models.mongoose

Find all DemoUser example:

await this.application.$models.mongoose.DemoUser.find()

// or

await this.application.$models.mongoose[ this.entity ].find()

Accessing Sequelize models

Lets suppose you need to handle the DemoUser table from SQL server from inside a service layer. All you need is to directly call the model object from application.$models.sequelize API, example:

Sequelize API object at application.$models API

this.application.$models.sequelize
