Node Js Php Serialize Class
JSON stringify in Node JS not serializing array of objects. (node js framework). I am trying to JSON.stringify one of the objects, but when I do that it omits one of the fields (rooms array below). JSON serialization of enum as string. Why does Google prepend while(1); to their JSON responses? Writing Awesome Node.JS API Using Decorators in TypeScript! One of my recent addiction was the usage of decorators, I was searching for ways to build cleaner and more concise code, and decorators.

Use the serialize() fu nction of the same module. In that module, the r equire. The best way to do this is to write a own serialize method which creates a JSON object with attributes, based on your getters. Normally you define a getter per attribute. So it should work for most cases (so you don't have to define a serialize method for each class).
I'm writing a simple serialization / deserialization framework for some application-specific objects.
Consider the following:
At this point, one can ask 'What does d1 have that d2 lacks?'
One approach that partially works is to manually assign the methods of d1 to d2:
This has a couple of disadvantages. First, I have to manually assign each method of d1 to d2. Second, d2 gets its own properties, and doesn't share slots using the prototype mechanism:
So my refined question is: given an object (e.g. d2), is there a way to associate it with the prototype of another object (e.g. d1) so it inherits the same behavior?

Node Js Php Serialize Classes
Object.create() and Object.getOwnPropertyDescriptors() is what you need.

The difference between this and OP's method is that this method sets prototype properties on the prototype, whereas OP's method sets properties directly on the object. You can see this when you loop through object own properties using for-in loop with hasOwnProperty() method:
With my method it outputs only _name, but with OP's method it outputs also getName.
Unfortunately, Object.getOwnPropertyDescriptors() is part of ECMAScript 2017 and it's supported only in Firefox for now, so you'll need to use Babel.
Alternatively, you can use Object.setPrototypeOf(). It has better browser support than Object.getOwnPropertyDescriptors(), but it's discouraged by MDN, because it's slow.
Node Js Php Serialize Class To Json
As I was writing this, I had the idea of creating a custom constructor that uses the deserialized JSON to initialize the object:
Update: how to dynamically find the class and assign the prototype
Driver all windows 7 hp laserjet 1020. As @Louis points out, @Gothdo's answer requires that you know what class the deserialized object belongs to. If you're willing to add the class name to the serialized object, you can use that to determine the class dynamically. So, for example, to expand on the OP's example:
Using the trick described in deserialize JSON to JAVASCRIPT object (but tweaked for Node.js) you can use a string to get a handle to a class prototype via Node.js's global object:
Now you can use that to dynamically reconstruct the object using @Gothdo's technique. Putting it all together:
