fix: add missing exports for subpath module

[khmm12]

Subpath exports should be defined via package.json exports field for ESM.

• https://webpack.js.org/configuration/module/#resolvefullyspecified
• https://www.typescriptlang.org/docs/handbook/esm-node.html
• https://nodejs.org/api/packages.html#subpath-exports

It's still not ESM compliant, because inside CJS packages ESM modules should have extension .mjs and all their imports should be fully specified import './events.mjs', not import './events'.

@khmm12 I just created #2272 to give this a bit more visibility and document my failed attempts at workarounds. Did you get this working for you?

[khmm12]

@tordans Yes, it works well with bundlers like webpack. But as I mentioned in the description the package is still not ESM compliant, therefore it's not compatible with strict environments like node.js. The next step should be ESM compliant package.

@khmm12 do you have experience with how to best do this? I am just reading about https://deno.com/blog/publish-esm-cjs-module-dnt which sounds nice but is based on Deno as an entry point…

Closing in favor of #2281
