While working with the buttercms NPM package in v2.3.0, I kept receiving the following Typescript error:
"Could not find a declaration file for module 'buttercms'. '/home/justi/projects/nv-web-platform/node_modules/buttercms/dist/butter.esm.js' implicitly has an 'any' type.
There are types at '/home/justi/projects/nv-web-platform/node_modules/buttercms/lib/butter.d.ts', but this result could not be resolved when respecting package.json "exports". The 'buttercms' library may need to update its package.json or typings."
From my research, I found an example at https://antfu.me/posts/publish-esm-and-cjs#tsup
It looks like when you split the exports between cjs and esm, you also need to export the types in package.json for the typings to apply to both exports.
I tested this by patching the package.json in my local node_modules and it fixes the issue.
Since I already did the research and it's a one-line fix, I figured I'd just submit a PR instead of an issue. I hope that's alright!
