mxgraph-type-definitions VS DefinitelyTyped

This first started as mxgraph-type-definitions. Most parts of mxGraph were covered progressively, and types became more accurate thanks to user feedback. Projects like grafana-flowcharting began using it.

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
