mapToClass is not working for ES6 class modules

[gimzani]

I have a class like this:

export default class MyClass {
  constructor(options) {
    this.prop = null;

    if(options) {
      this.prop = options.prop || this.prop;
    }
  }
}

Then I set it up like:

import MyClass from './some/loc/MyClass';

db.MyTable.mapToClass(MyClass);

When I call the mapToClass, I have the imported Class ready - but it does not work. I call the data with 'get' and just get the raw data. It seems to just ignore it all together. Am I just not understanding how this works?

mapToClass() should work with ES6 classes. Please link to an example in jsitor.com or similar showing what you do and explain what you were expecting.

I can't find an online code editor that allows JS module imports.

I'm using WebPack and I'm importing one file into another:

The Module in this case is "Friend.js"

// 'models/Friend.js'
//----------------------------------------------
export default class Friend {
  constructor(options) {
    this.id = 0;
    this.name = null;
    this.shoeSize = null;

    if(options) {
      this.id = options.id || this.id;
      this.name = options.name || this.name;
      this.shoeSize = options.shoeSize || this.shoeSize;
    }
  }
}

The main file is 'main.js' - (from your example)

// main.js
//----------------------------------------------
import Dexie from 'dexie';
import Friend from './models/Friend'

var db = new Dexie("FriendsDB");
db.version(1).stores({
    friends: "++id,name,shoeSize,address.city"
});

db.friends.mapToClass(Friend);  // it's like this gets ignored - or maybe it can't call constructor()?

db.friends.where("name").startsWithIgnoreCase("d").each(function(friend) {

    assert (friend instanceof Friend);  // = false
	
    friend.log();
}).catch(function (e) {
    console.error(e);
});

ok thanks. I'll try repro it. In jsitor you can just include dexie in a script tag in the html part. For webpack style online editor, check codesandbox. For example cloning this Dexie-based project
