If I use typescript in my project, would that make the usage of prop-types in React obsolete? With prop-types I would have to go through the grunt of defining types but with typescript, this step would be negated. AM I correct in my thinking?

Props are required in TypeScript In the prop-types package, all props are optional by default. To make a prop required, you will have to use . isRequired explicitly.
Props and PropTypes are important mechanisms for passing read-only attributes between React components. We can use React props, short for properties, to send data from one component to another. If a component receives the wrong type of props, it can cause bugs and unexpected errors in your app.
PropTypes will help here because they validate data on run time and if some of the data type is wrong then you will get an error that this type is wrong. Using data from a library that may not have adequate or accurate typings, if any.
Situations for both In case you were wondering, an interface can also extend an object type defined by a type alias and vice versa. Both can even use generic types. These are the common cases in which we define types for objects, especially React prop types. So 95%+ of the time* either one works fine.
Sounds about right. When you use TypeScript you can define the props via an interface.
interface ButtonProps {
text: string,
shadow?: boolean
}
const Button: React.FunctionComponent<ButtonProps> = props => {
return ( /* [...] */ );
};
