Summary: After adding this plugin, you just need to install https://github.com/AtomLinter/linter-eslint Atom package to surface ESLint errors(including prettier errors) in Nuclide linter UI. You also got auto-fix support in the Nuclide UI. Similarly, in VSCode, you can install https://marketplace.visualstudio.com/items?itemName=dbaeumer.vscode-eslint plugin to surface ESLint error in VSCode UI. One caveat is that, eslint-plugin-prettier uses its own version of prettier(1.3.1) which may diverge from what we want. If we really found a file that diverge in formatting, we may have to add it into .eslintignore to ignore from UI/linter.
