As of v6.2.2, tsup is using a version of esbuild that supports the new JSX transform, so you should be able to specify jsxImportSource (along with "jsx": "react-jsx") in tsconfig.json and have tsup/esbuild pick it up automatically.

@gavinsharp thanks for the heads up, just upgraded and tested, working as expected!

@gavinsharp as of 8.0.0, jsxImportSource doesn't exist on the Options type. And tsup doesn't even pass jsxImportSource to esbuild if you pass it with as any. Simply doesn't work.

I was suggesting esbuild would read jsxImportSource directly from the tsconfig on its own, independently of tsup. It's possible something has changed since, but that was working for me when I made the comment.

Ah distinct difference there. I've a patch that I'm going to open a PR for that adds support to the Options so tsconfig doesn't have to be relied upon.
