Hi @iamrajiv ,

Thanks for introducing the `prettier to our project!

After I learn about it, I think it would be great if we can have a prettier linter in our community.

Could you please read the https://prettier.io/docs/en/integrating-with-linters.html and propose a solution? For example, we can add the prettier linting plugin to @chatie/eslint-config, so that all the Wechaty community projects can be benefited from it.

I think what we need is a linter which will throw an error by following our config file, instead of a rewriter.

For this PR, it will be good to go after:

1. Follow my review: always keep the trailing comma, and
2. Make the CI green by fixing the code.

Thank you very much!
