DefinitelyTyped VS create-react-app

Prior to React 18, it used to include an implicit children prop, making it suitable for components expected to have children. For a long time, though, the implicit children prop type has been removed according to React 18's type changes.

Additionally, because TypeScript has a well established and widely used install-base, there are already many different definition files in the wild for supporting non-TypeScript supporting projects. One of the more extensive collections of these typings lives at the DefinitelyTyped repository, which publishes the package's community typings under the package names @types/your-package-name (where your-package-name is the name of the project you're looking for typings of) that you can look for on your package manager.

Their type definition for HAR request isn't exported https://github.com/DefinitelyTyped/DefinitelyTyped/blob/mast...

type NumberOrString = number | string; type Status = "idle" | "loading" | "success" | "failure" // React useState, can receive a value or a function as parameter to serve as initial value. // https://github.com/DefinitelyTyped/DefinitelyTyped/blob/a03856975a17eba524739676affbf70ac4078176/types/react/v17/index.d.ts#L920 function useState(initialState: S | (() => S)): [S, Dispatch>];

The TypeScript pull request was merged, so Sebastian (who helps maintain the React type definitions) exercised new powers in this pull request to the DefinitelyTyped repository for the React type definitions. At the time of writing, this pull request is still open, but once merged and shipped the React community we will feel its benefits.

there is an open issue: https://github.com/DefinitelyTyped/DefinitelyTyped/issues/61616

Relatively infrequently. Normally, if an npm package is popular and doesn’t have its own types, there will be a community provided types declaration file available from https://github.com/DefinitelyTyped/DefinitelyTyped

Create React App (CRA) abstracts away the complexity of configuring Webpack, Babel, and other build tools, allowing developers to focus on writing React code. It includes features such as hot module reloading for efficient development.

Immerse yourself in the official Create React App documentation for a deeper understanding.

Create React App (https://create-react-app.dev/)

- And ofc, there are some templates/frameworks that bring something of that together (https://create-react-app.dev/; maybe https://vitejs.dev/) - google for templates.

I recommend finding some friend with modern experience or at least some youtube tutorials or at least some learning course. That would help you to catch up on the best way to bootstrap your first project. Then you can practice.

What's the connection?
