virtual-storage

Virtual Storage (node) for those who do not have access to localStorage like Dialogflow

Insert in project

vStorage = require('virtual-storage');

Basic Usage

Create a virtual storage:

vStorage.set('name', 'value')

Read virtual storage:

vStorage.get('name') // => 'value'
vStorage.get('nothing') // => undefined

Delete virtual storage:

vStorage.remove('name')

Delete virtual storage by name:

vStorage.remove('name')

Delete all virtual storage:

vStorage.remove()

When deleting a virtual storage it will generate a empty array {}

Simple set / get example:

let json = [{title:'Title 1', description:'Descriptions 1'},{title:'Title 2', description:'Descriptions 2'}];
vStorage.set('json_infos', json);

Get json infos

let json_info = vStorage.get('json_infos');
 
let tile_1 = json_info[0].title; // Title 1
let description_2 = json_info[1].description // Descriptions 2

For Dialogflow

You may need a uniq name / key for your app. like Dialogflow.

Create a uniq name for Dialogflow:

You can create a uniq id at the top of your app.js file like this.

const sessionID = new Date().getTime(); // or any code you may find on the web

vStorage.set('name'+sessionID, store_json_response);

Get stored values

vStorage.get('name'+sessionID);

Or with Dialogflow session id.

let sessionID = vStorage.set('json_list'+SessionID(conv.body.session);

vStorage.set('uniq_name'+sessionID, store_json_response);

Get stored values

let getmyjsonStorage = vStorage.get('uniq_name'+sessionID);

// Get only the id part from Dialogflow conv response
function SessionID(sID) {
  var n = sID.lastIndexOf('/');
  return sID.substring(n + 1);
}
