Show Notes 04:55 - Components Strategies Example: type Props = { value: string; } const App = (props: Props) => Return type? JSX.Element FC or FunctionComponent It’s discouraged for this reason: It means that all components accept children, even if they're not supposed to It could be useful for a return type 12:13 - Props Default props: const defaultJoke: JokeProps = { joke: 'LOL JOE', id: 'YEAH', status: 200, }; function JokeItem({ joke = defaultJoke }: JokeProps): JSX.Element { return ( {joke.joke} = {joke.id} ); } Because props are always destructured, you often have to make a new type for your props. You can’t just type each argument by itself. 18:38 - State Just like Generics, State can be inferred If your type is simple and you’re using useState, it just works: const [user, setUser] = useState(null); 22:27 - useEffect Nothing special required Good use of void: If you want to use a Promise function but not worry about await or .then(), you can pop a void in front of it: useEffect(() => { console.log('Mounted'); // getJoke().then(console.log).catch(console.error); void getJoke(); }, [getJoke]); 26:09 - Refs Very similar to state however some interesting things with null: const ref1 = useRef(null!); “Instantiating the ref with a current value of null but lying to TypeScript that it’s not null.” 29:33 - Custom Hooks This is a great use case for Tuples 31:00 - Context This is probably the most complex thing in this list First define the types Use generic to pass in types OR null This can also be non-null if you have default values in createContext: const AppCtx = React.createContext(null); 35:21 - Events The React events system is better than Vanilla JS Can handle them inline and have it inferred: onClick={e ⇒ yeah(e.target)} const onSetType = (e: React.ChangeEvent) => setType(e.target.value) React has a bunch of events built in — many of them take a Generic argument so you can specify the type of element that triggered it. Handy for native API methods like play and pause. 39:27 - ForwardRef Again use of to pass in forwarded ref type as param 1, Props types as param 2: type Props = { children: React.ReactNode; type: "submit" | "button" }; export type Ref = HTMLButtonElement; export const FancyButton = React.forwardRef((props, ref) => ( {props.children} )); 41:30 - ESLint Typescript-react is good Extend your own Most JS rules apply to TS 46:20 - React as Global React 17 Also add JSX: True to eslint globals for typing things like JSX.Element global.d.ts import * as react from "react" import * as react_dom from "react-dom" declare global { type React = typeof react type ReactDOM = typeof react_dom } 48:08 - TSConfig jsx: "react" React emit .js files with JSX changed Preserve .jsx file output React-native → .js files with jsx not changed 53:05 - Frameworks?
