intellij idea - ESLint: Insert `?` (prettier/prettier) error in WebStorm

Question

On every time on file save ESLint gives this error:

ESLint: Insert ? (prettier/prettier)

When I add new line, it remove it and still shows this error.

How can I prevent this ESLint error in WebStorm?

Answer 1

To prevent it on intellij (Web Storm etc), set editor config to add new line at the end of all files.

You can set this: Settings → Editor → General → Ensure line feed at file end on Save
