Description

This is update for following TODO.
Updated package.json in "@wdio/electron-utils/log" to fix this TODO.

TODO: Fix CJS import of log from '@wdio/electron-utils/log'

Memo

In my understand, when CommonJS is set module at tsconfig.json, then moduleResolution will be set node10 (same as node) as a default.(docs)
Then exports field of package.json(imported module side) will be ignored. (exports field is added Node v12.7.0.)
So this PR adds a typesVersions field and tells typescript to the appropriate types file.

[mato533]

In order to avoid such complications, one idea is to introduce a bundler such as rollup and build both esm and cjs source code from esm.

I think the bundler approach sounds like the best option to reduce the complexity of CJS / ESM here, I'll raise a ticket for that, but we can merge this fix in the meantime. I wasn't aware of the typesVersions field - I am now...

Thanks for the contribution!

UPDATE: Raised #880 to cover the above.
