HealthStorageODM

The healthstorage-odm serves the HS storage api. It provides a simple structure to use the interface efficiently and purposefully.

Installing

First install node.js.

npm install healthstorage-odm

Importing

// Using ES6 imports
import HealthStorageODM from 'healthstorage-odm';

Overview

Defining a HsClient

It is possible to create multiple HsClient instances for diffrent servers. Creating a new Hsclient works like this:

// By calling constructor
const CLIENT = new HealthStorageODM({
  serverUrl: 'https://your.server.url',
  adapter: 'adapter'
});

// By calling static createClient
const CLIENT = HealthStorageODM.createClient({
  serverUrl: 'https://your.server.url',
  adapter: 'adpater'
});

If there are no parameters set, it will take http://localhost:8080 as a default client server url and hsStorage as default adapter.

The created client returns an instance for further use.

Defining a HsInstance

Defining a HsInstance is realized by calling the define function from created Hsclient. It returns an instance of HsInstance which holds the api functionallity.

Example:

// Create a HsInstance with schema data
const sampleSchema = CLIENT.define({
  title: 'SomeSchema',
  properties: {
    title: {
      type: HealthStorageODM.STRING
    },
    description: {
      type: HealthStorageODM.STRING
    },
    price: {
      type: HealthStorageODM.DOUBLE
    },
    online: {
      type: HealthStorageODM.BOOLEAN
    },
    hits: {
      type: HealthStorageODM.INTEGER
    }
  },
  options: {
    required: [md],
    oId: '1a8a1956-fde7-486f-91b8-ce9a3d9b4be1', // uuid
    id: '5cc6ae3e-bf8f-4be5-b6fb-5de55ca9fd8a' // uuid
  }
})

HsModel

A HsModel is always used for a single item returned in list, create, update etc. It holds the single item information and function to update, lock, delete itself. The properties are dynamically assigned as getter/setter and stored additionally in the _dataValues property of the model.

  // Simple example of HsModel
  HsModel = {
    HsAdapter: HsAdapter {client: {…}},
    _dataValues: {
      id: "", //uuid
      title: "SampleTitle", 
      isCompleted: false, 
      blobRefs: […]
      md: {…}
    },
    id: (...),
    isCompleted: (...),
    lockValue: (...),
    md: (...),
    title: (...),
    get id: ƒ (),
    set id: ƒ (value),
    get isCompleted: ƒ ()
    set isCompleted: ƒ (value),
    get md: ƒ (),
    set md: ƒ (value),
    get title: ƒ (),
    set title: ƒ (value)
  }
