Add optional support for ESlint and Prettier
Since I'm using ESLint and Prettier throughout most of my projects, I want to add (optional) support for it in the CLI.
I feel three options are appropriate here:
- Disable ESLint and Prettier.
- Use only ESLint.
- Use both ESLint with Prettier.
My reasoning is that with Prettier, ESLint show if code doesn't follow Prettier's rules, and indicate what will happen if the file is saved. So using Prettier without ESLint is not a useful option.
