Storage connector

Installation

If you haven’t yet installed the storage component, in your application root directory, enter:

$ npm install loopback-component-storage --save

This will install the module from npm and add it as a dependency to the application’s package.json file.

Creating a storage data source

Create a new push data source with the data source generator:

$ apic create --type datasource

$ slc loopback:datasource

When prompted, select other as the connector.

At the prompt “Enter the connector name without the loopback-connector- prefix,” enter storage.

This creates an entry in datasources.json like this (for example):

...
"myStorageDataSource": {
  "name": "myStorageDataSource",
  "connector": "storage"
}
...

Configuring a storage data source

Configure a storage data source by editing the datasources.json file, for example as shown in the storage service example:

...
"myStorageDataSource": {
  "name": "myStorageDataSource",
  "connector": "storage",
  "provider": "filesystem",
  "root": "./server/storage"
}
...

Creating a storage model

Use the model generator to create a new model, then edit the model.json file,  as shown in the storage service example:

{
  "name": "container",
  "base": "Model",
  "properties": {},
  "validations": [],
  "relations": {},
  "acls": [],
  "methods": []
}

Connect the model to the storage data source

...
  "container": {
    "dataSource": "myStorageDataSource",
    "public": true
  }
...
