I'm exporting a class into my main code, But I'm not able to use any function of it. Including my singleton pattern function to instance it.
index.js :
import __system from '../crud-js/system.js';
const s = __system.getInstance();
system.js :
export default class system{
motoboys = [];
clientes = [];
static INSTANCE = new system();
constructor() {
}
getInstance(){
return INSTANCE;
}
error :
const s = __system.getInstance();
^
TypeError: __system.getInstance is not a function

getInstance is written as an instance method in your class, but you are trying to call it as a static method.
Instead do this:
static get instance() {
return system.INSTANCE;
}
and use it like this:
const s = __system.instance;
