Since the filename pointed at by `default` and `import` (`empty`) is not identical to the filename of the `d.ts` file (`index`), the top level `types` field is not enough when using `"moduleResolution":"Node16"` and TypeScript `4.7`. To fix this, `types` must be explicitly specified inside the `exports` object in addition to the top level `types` field. See [firebase/firebase-js-sdk#6300](/firebase/firebase-js-sdk/issues/6300) and [microsoft/playwright#14428](/microsoft/playwright/pull/14428)

There was a problem hiding this comment.
Per the TS documentation, types should be first in this object? Does not seem to matter in my testing, just pointing out: https://www.typescriptlang.org/docs/handbook/esm-node.html

As seen in kripod#11, the `types` field needs to be exported for modern node resolution methods to work in typescript.
