Doing so prevents any named imports leaking into the output type definitions (.d.ts files) and follows with what seems to be the React official recommendations [1]. The more 'correct' fix would be only import those components that are needed by each component, but that's a bigger change. [1] facebook/react#18102 Fixes stripe#569
…l patterns updated in v19 of React.

@jake-brandt Are you noticing any incompatibilities, such as this issue outlined, when using react-stripe-js in your project, that requires a bump to React 19? |
Hi @rvolyar-stripe, assuming the dependent project employs version overrides in their I haven't run into any issues with the JSX global namespace being moved under React's; but I'm aware of that change from when we upgraded our own application to v19. Other changes we ran into were mostly around route arguments, cookies, etc. being Promises now. I don't see how that will work with the v18 React target unless you aren't using that functionality at all; hence I was a bit surprised when the application both built and actually still added a payment card lol. |

Maybe you should find another way to test this assertion

sounds like killing the thermometer. Maybe there is another way to test this call because this function is supposed to be called

Summary & motivation
This is a rebase with a few updated unit tests, forked from #585 (original PR by @bagedevimo). It also updates the Storybook React dependency from v6 to v9 to allow us to move up to React v19. I attempted to run the Storybook codemods but no possible migrations were detected, nor is the core Storybook package a part of the project, so my confidence in Storybook working with this is slim. But it's not blocking React 19 now at least.

Testing & documentation
Existing unit tests were updated to work with the new React 19 patterns. A few tests actually removed original spies as the execution of the test without exception is enough to prove that those test cases pass. Two tests remain failing, likely due to significant changes in promise/async resolution in React 19.
