re: A Beginners Guide to using Typescript with React VIEW POST


My bread and butter with React and TypeScript is to type the functional components with the React.FC generic type. With your example above, that would be something like this:

export const StandardComponent: React.FC<{ title?: string}> = 
({ children, title = 'Dr.'}) => {
 // rest of the code

Why? it adds automatically children for you, makes the signature easier to read (IMHO) and checks the return type.

Note: FC is a short-hand for FunctionComponent


Cool! I've used FunctionComponent in the past but didn't realize it actually added children for you.

Thanks for the tip!


The React TypeScript cheat sheet recommends doing them using the shorter version of Ben's syntax:

type AppProps = { message: string }; /* could also use interface */
const App = ({ message }: AppProps) => {message};
