Eslint ignore all exept js fles

Question

How can I ignore all files in the directory scr/ except the .js files? (using a .eslintignore file)

I tried using

scr/*
!scr/*.js

Answer 1

A single star * only matches filenames, if you have directories you'll need to be using ** as part of the match:

# Exclude **/scr/
scr/
# ...but not **/scr/**/*.js
!scr/**/*.js

Answer 2

In this case it might be easier to target javascript files instead of trying to ignore all other files. Something like eslint scr/**/*.js
