re: React Higher-Order Components in TypeScript made simple VIEW POST


Hey there Dan, MadProps for this article.

Going forward with this example, how would you use ReactDOM.render with this component?

Say we continue with this:

export const Demo = clickCounted()(DemoComponent);

Then our calling code would do

ReactDOM.render(<Demo {...stuff} />, document.getElementById('container'))

And we'd have to pass in something into stuff, which is of type <TOriginalProps & InjectedProps> Is that right?

So what's the point of having injected props calculated within the HOC definition? Am I missing something? If I want to render the Demo HOC, don't I have to give it all the props it needs? I think I'm missing the point...


Hi, thanks for the MadProps :)

<Demo> has props of type TOriginalProps & ExternalProps (no InjectedProps).

<DemoComponent> has props of type TOriginalProps & InjectedProps.

Look at the diagram at the start of the article, it should make the prop types flow clearer :)
