Sorry, I searched but couldn't find an existing issue for this...

Should ESLint ignore the "node_modules/**" folder by default?

I have a sample Node project with one *.js file (and ESLint installed globally) and typed:

$ eslint .

...
node_modules/syntax-error/test/sources/check.js
  5:30  error  Unexpected identifier

✖ 88164 problems

real    0m33.670s
user    0m30.912s
sys     0m0.958s

The command took ~30s and found 88k problems in my node_modules/ folder. :/
I think we'd want to automatically ignore the "node_modules/**" folder since it'd be a better "out of the box" experience.

Workaround:

Put node_modules/** in the project's .eslintignore file.

$ echo "node_modules/**" > .eslintignore

$ cat .eslintignore
node_modules/**

$ time eslint .

index.js
  1:0  error  'console' is not defined      no-undef
  1:0  error  Unexpected console statement  no-console

node_modules/hapi/test/templates/valid/helpers/.hidden.js
  1:16  error  Strings must use doublequote  quotes

✖ 3 problems

real    0m0.346s
user    0m0.293s
sys     0m0.053s

Not sure why, but even though I have node_modules/** in my .eslintignore file, it looks like it's linting node_modules/hapi/test/templates/valid/helpers/.hidden.js.
