I'm Bonk, and I've done a quick review of your PR.

This PR updates the React Workers template to follow the new Vite v9 React starter design. I found one actionable issue:

1. TypeScript type safety regression in App.tsx — The old TS template properly typed the API response with res.json() as Promise<{ name: string }>. The new version drops this, making data implicitly any. I posted a suggestion comment on line 40 of the TS template with the fix.

The review has been submitted to PR #13513.

This looks really great. Thanks @edmundhung! We also need to update the variants as these are no longer up to date:

workers-sdk/packages/create-cloudflare/templates/react/workers/c3.ts

Lines 119 to 140 in 8ca78bb

	const variantsOptions = [
	{
	value: "react-ts",
	lang: "ts",
	label: "TypeScript",
	},
	{
	value: "react-swc-ts",
	lang: "ts",
	label: "TypeScript + SWC",
	},
	{
	value: "react",
	lang: "js",
	label: "JavaScript",
	},
	{
	value: "react-swc",
	lang: "js",
	label: "JavaScript + SWC",
	},
	];

The available variants in create-vite are these:

We should probably include the first four i.e. TypeScript/JavaScript with and without the compiler. Or maybe don't bother with the compiler and just have TypeScript and JavaScript? Up to you.

@jamesopstad I dropped the swc variants as they are no longer supported with create-vite. I don't think it's worth including the react compiler variants so I leave it with just a js and ts variants for now.
