it's possible to follow this example as an alternative but that requires deleting isObject export from main file (is it needed tho?)

@fi3ework any objections on merging this one?
Fixes this issue:

@wight554 thanks for the PR, I was wondering is there way to also use default export in ESM which will be aligned with CJS?

Ideally .d.ts for CJS and .d.mts for ESM, so CJS file definition can have exported namespace, like in example.
But I think Typescript compiler doesn't create separate type definitions from .ts files

Does a conditional export works for this? https://devblogs.microsoft.com/typescript/announcing-typescript-4-7-rc/#package-json-exports-imports-and-self-referencing ESM and CJS can use different types entries and we can build different types fils before publishing

Well having mjs typings requires mjs module, won't it be overhead ti to have 2 versions if plugin if it works as is?
It's just esm requires named cjs exports to work properly with cjs modules

@fi3ework added changes to make module cjs style, can you build and attach output .d.ts file?
Unfortunately I couldn't get build command run successfully on 2 machines, always fails with:

I'm not sure if export = plugin is a valid ES syntax, if so, could you please paste a link for that?

I think the previous implementation is simple enough to handle the nodenext for now.

I think you're right. Maybe we can export consistently of CJS and ESM in the next minor version. Adding another export is good enough for now. Would like to revert to the prev version and make it merged. Thanks!

It's valid for CJS, but yeah previous version was cleaner

We hope to resolve this in a more ESM flavor way as it's becoming more and more mainstream.

revert to the prev version

There's an extra semicolon that fails the CI 👀

'Plugin' also should be changed to 'checker'
