How to never add WebStorm .idea folder to git ever again

Frequently when you work with an open-source repository you might accidentally commit your .idea folder to it. Maintainers of these repositories frown upon you changing their holy .gitignore file to prevent this problem. They don't want to hear about your crazy ideas of using a closed-source, commercial, and paid-for IDE.

There is a simple trick to help that I wish I discovered years ago.

The steps are very simple:

1) Create a global .gitignore file:

touch ~/.gitignore_global

2) adding the '.idea' line to it in any way you want, but preferably with your expensive IDE:

webstorm ~/.gitignore_global # or vim ~/.gitignore_global or .. you get the point

3) and then configure git to use it:

git config --global core.excludesfile ~/.gitignore_global

That's it! You will never have to feel like a sapper on a minefield again.

    From time to time you might need to expose your locally running service to the external world - for example you might want to test a webhook that calls your service. To speed up the test/development feedback loop it would be great to be able to point that webhook to your local machine.
