The shortcomings of building based on the default node image are as follows: Docker image builds are inconsistent. Just like we’re using lockfiles to get a deterministic npm install behavior every time we install npm packages, we’d also like to get deterministic docker image builds. If we build the image from node—which effectively means the node:latest tag—then every build will pull a newly built

Wrapping/MirroringWrapping/Mirroring a HTML ElementUsecase: you want to make a <Button> that takes all the normal props of <button> and does extra stuff. Strategy: extend React.ComponentPropsWithoutRef<'button'> // usage function App() { // Type '"foo"' is not assignable to type '"button" | "submit" | "reset" | undefined'.(2322) // return <Button type="foo"> sldkj </Button> // no error return <B
These can be written as normal functions that take a props argument and return a JSX element. // Declaring type of props - see "Typing Component Props" for more examples type AppProps = { message: string; }; /* use `interface` if exporting so that consumers can extend */ // Easiest way to declare a Function Component; return type is inferred. const App = ({ message }: AppProps) => <div>{message}</
This is intended as a basic orientation and reference for React developers familiarizing with TypeScript. Basic Prop Types ExamplesA list of TypeScript types you will likely use in a React+TypeScript app: type AppProps = { message: string; count: number; disabled: boolean; /** array of a type! */ names: string[]; /** string literals to specify exact string values, with a union type to join them t
The @types typings export both "public" types meant for your use as well as "private" types that are for internal use.

General interview tipsClarify any assumptions you made subconsciously. Many questions are under-specified on purpose. Always validate input first. Check for invalid/empty/negative/different type input. Never assume you are given the valid parameters. Alternatively, clarify with the interviewer whether you can assume valid input (usually yes), which can save you time from writing code that does in
