webpack CLI error - [webpack-cli] Error: Unknown option '--inline'

Question

When I try to start my Preact app using npm start it gives this error

[webpack-cli] Error: Unknown option '--inline'

This is my package.json script

"start": "webpack-dev-server --inline --hot --progress --content-base public --port 3333"

Answer 1

It's been deprecated, and is true by default now.

You can't use inline option (it will be always true in next major).

I couldn't find anything more authoritative about the change
