fix: move package to ESM-Only and fix package exports

[userquin]

I cannot build date-picker-input on my local, once the corresponding dts generated, the subpackage types should be fixed: dist/date-picker-input/date-picker-input.d.ts missing.

Lit is using ESM-Only, you can check latest and 2.8.0 versions (v2.8.0 being used in 6 rc33):

• lit v3.1.1 types: https://arethetypeswrong.github.io/?p=lit%403.1.1
• lit v2.8.0 types: https://arethetypeswrong.github.io/?p=lit%402.8.0

Check screenshot in this comment: https://github.com/motss/app-datepicker/issues/222#issuecomment-1898572994

pnpm build && pnpm pack, go to https://arethetypeswrong.github.io/ and upload the tgz file: refresh page between builds.

EDIT: I can also include "packageManager": "[email protected]" in the package.json

You can use a bundler instead using tsc, for example you can use rollup, tsup or unbuild, this way you can write the build in the corresponding folders.

As an example, you can check lit (using rollup) package, the corresponding dts files in the root folder and subpackage exports with the corresponding folders (index.dts, decorators.d.ts, async-directive.d.ts, directives.d.ts... in root folder, decorators folder with the corresponding dts inside. This way when using Node/Node10, Node 16 or Bundler TS will not complain when resolving types:
