Can't get custom class loaded

help
1

Hello,

I cannot load a file containing a class which extend another class defined in another file. I tried putting it together in lib directory as i would like to use them in the project but even if the name of the second alphabetically after. It doesn’t work. Then i tried to just put the second out of the lib folder but still when it comes to load the second class, it can’t access the first.

2 classes like :

HfrObject.js :

class HfrObject {
	constructor(item) {
		...
	}
}

HfrMyCustom.js :

class HfrMyCustom extends  HfrObject {
	constructor(item) {
		...
	}
}

And HfrMyCustom is used in my react components.

the error is :

W20160303-13:53:48.134(1)? (STDERR) ReferenceError: HfrObject is not defined
W20160303-13:53:48.134(1)? (STDERR)     at modules/Custom/lib/HfrMyCustom.js:1:28

Where should i put those files please?

If you’re on 1.3, use import/export. If not, you have to declare your class as a global variable. Like so:
HfrObject = class HfrObject {}

If you’re still getting the error after that, it might be a load order issue. Which will also be easily resolved by upgrading to 1.3 and using import/export. But, if you don’t want to go with 1.3 (yet), you have to follow the load order rules. They’re specified in the docs if I’m not mistaken.

You’re running into file scope issues, where the class is locally scoped. You could do HfrObject = class HfrObject {... to define a globally scoped reference, or use modules by updating to the 1.3 beta release.
