You need to rewrite your Test component in this way const Test= <T,>(props:TestProps<T>) => ( <span>Some component logic</span> ); Can you show the same with React.FC<TestProps>? It is impossible to do with FC. This is FC implementation: interface FunctionComponent<P = {}> { (props: PropsWithChildren<P>, context?: any): ReactElement<any, any> | null; // … other static properties … Read more
I have a solution, it seems that there are a ton of breaking changes in the 18.0.1 type definitions. Like you, I could not solve it by rolling back to earlier versions, but investigation lead me to discover that this was because ‘react-router’ among others was bringing in the ‘18.0.1’ version. to get around this, … Read more
I had the same error with <Text></Text> and it was because I had not imported the component.
You require to extract the ref type elsewhere: interface RefObject { SayHi: () => void } then just refer to it in both places const Child = forwardRef((props: {name: string}, ref: Ref<RefObject>)=> { const {name} = props; useImperativeHandle(ref, () => ({ SayHi })); function SayHi() { console.log(“Hello ” + name); } return <div>{name}</div>; }); const … Read more

Also you CANNOT use “HTMLElement” as your ref type, you have to be more specific, so for me … Read more

trevorsg, you need to pass the button properties: import * as React from ‘react’ type ButtonProps = React.HTMLProps<HTMLButtonElement> const FancyButton = React.forwardRef<HTMLButtonElement, ButtonProps>((props, ref) => ( <button type=”button” ref={ref} className=”FancyButton”> {props.children} </button> )) // You can now get a ref directly to the DOM button: const ref = React.createRef<HTMLButtonElement>() <FancyButton ref={ref}>Click me!</FancyButton> ADDED: In recent … Read more
You can change the definition of your component to allow the react html button props class MyButton extends React.Component<MyButtonProps & React.HTMLProps<HTMLButtonElement>, {}> { render() { return <button {…this.props}/>; } } That will tell the typescript compiler that you want to enter the button props along with ‘MyButtonProps’
