This Gist presents a new design of class-based object construction in ES6 that does not require use of the two-phase @@create protocol.
One of the characteristics of this proposal is that subclass constructors must explicitly super invoke their superclass's constructor if they wish to use the base class' object allocation and initialization logic.
An alternative version of this design automatically invokes the base constructor in most situations.
// getComponent is a function that returns a promise for a component | |
// It will not be called until the first mount | |
function asyncComponent(getComponent) { | |
return class AsyncComponent extends React.Component { | |
static Component = null; | |
state = { Component: AsyncComponent.Component }; | |
componentWillMount() { | |
if (!this.state.Component) { | |
getComponent().then(Component => { |
import { describe, it, expect, spyOn } from "bun:test"; | |
