ServiceWorker for github pages

This is a ServiceWorker template to turn small github pages into offline ready app.

Why ?

Whenever I make small tools & toys, I create github repo and make a demo page using github pages (like this one).
Often these "apps" are just an index.html file with all the nessesary CSS and JavaScript in it (or maybe 2-3 html/css/js files). I wanted to cache these files so that I can access my tools offline as well.

Notes

Make sure your github pages have HTTPS enforced, you can check Settings > GitHub Pages > Enforce HTTPS of your repository.

'Zero Width Space' character

I had some trouble with this character in a client project, it was hidden inside a configuration string which is validated in the clients API. It's basically invisible, literally a space character with zero width, it could not be seen but it was breaking at the API because it would not validate, causing problems with hundreds of user accounts.

The Unicode value of this character is U+200B, and it's evil, very evil. Lying in wait to break your applications while leaving no sign of it's presence...

It also has some friends, check the answer of this Stack Overflow question

In my project, it was one of my colleuges who managed to find the character, he re-copied the string into the code and Git showed that the line had been changed, even though all the Git GUI's didn't actually show any difference. He ran git diff in the command line and this did show the Unicode character being deleted, that's somet
