How to safely access instance properties declared in a class component with createRef

Open urielvan opened this issue 6 years ago • 3 comments

I have a child component connected by redux

class Child extends React.Component {
    foo () {}
}

export default connect()(Child);

and a parent contains it

class Parent extends React.Component {
    private childRef: React.RefObject<Child> = React.createRef()

    bar () {
        if (this.childRef.current) {
            /*
             * here typescript complains that 
             * Property 'foo' does not exist on
             * type 'ConnectedComponentClass<typeof Child...'
             */
            this.childRef.current.foo();
        }
    }

    render () {
        return (
            <Child ref={this.childRef} />
        );
    }
}

I've tried to set the generic type
