Usage Summary

Code

// Include library
const PersistentObjectES6 = require('persistent-object-es6');

// Extends your class - required
class FlatAssObject extends PersistentObjectES6 {

  constructor() {
    // Initialize it - required at the beginning of the constructor
    super('this-flat-ass-object-unique-name', 'Session');

    // Your class declaration here
    this.var1 = null;
    this.var2 = '';

    // Array and Object properties are not supported
    this.var3 = ['blah', 'blah'];
    this.var4 = {foo: 'blah', bar: 'blah'};

    // Create it - required at the end of the constructor
    return this.create();
  }
  
  // Your class methods here
  
  setVar1(val) {
    this.var1 = val;
  }
  
  getVar1() {
    return this.var1;
  }
  
  setVar2(val) {
    this.var2 = val;
  }
  
  getVar2() {
    return this.var2;
  }
}

// Instantiate your object
var flatAssObject = new FlatAssObject();
// Modify it
flatAssObject.var1 = 'not null';
flatAssObject.var2 = 'not empty';

// Later somewhere in your application, you redeclare this object
var flatAssObject2 = new FlatAssObject();
// Will return 'not null'
console.log(flatAssObject2.var1);
// Will return 'not empty'
console.log(flatAssObject2.var2);
