Service Workers are coming to Safari, it seems. This is my most anticipated and waited web platform feature (or whatever). Really. I’ve known the technology, played with it and deployed it into production on two web apps but it has always irritated me to not have it available for all users. Of course, the platform being what it is, you can never expect all users to have all the bells and whistles in their browsers, but still. Safari lacking behind Chrome, Firefox and Edge has been a painpoint since my user base has 30 % iOS coverage.
This is really great.
If you are a modern web developer or interested in these sorts of things but don’t know about Service Workers, now is a good time to dig into them. I suggest you read Google’s Web Fundamentals series’ introduction post, check out the videos and slides and play with some code on the ServiceWorker Cookbook.
