Introduction to Service Workers

Service workers are at the core of PWA techniques for resource-caching and push notifications. This video covers what a Service Worker is, what it can do, and the Service Worker lifecycle in the browser.

Hi there, Can i use service worker in local network if clients accept my certs? I will be greatfull for any help.

At 7:30 you say that the service worker, if given the `/app/` scope, can control `/app`, but then at 7:40 you say that it cannot control `/app`. Was a slash missing on the first one?

(If that's the case, I feel like there should be a clearer distinction between `/app` and `/app/` at 7:25.)

Why does it say [DEPRECATED] in the title ?

[pwzlynh]

it`s the perfect idea, because not need install app.
Browser (www) -> Home Screen (manifest.json) -> Enjoy
Nice idea to make workers API with push messages API in iOS and Android "when all apps and browser closed" (!sic)
Its the most interesting for business!

Hi i am working on PWA that uses Service Workers. In that i am caching index.html for offline use. But after deployment some times service worker still serves old index.html. If i do hard refresh or by pass sw.js everything works fine but in normal reload all calls are failing. how to solve this issue? Please help me out.


Note: I am using reactjs and create-react-app.

This may not be nice of me to say, but I'm zoning out trying to listen to this... I'm going to have to go find a text article or slides.

Great and interesting info..well done ! very useful
Im wondering, if i can keep the powerful core of a PWA and launch this to an iOS app store
Would be possible ?
I a wrapper is used to make the PWA as hybrid (for app stores ) we will still have the service workers, working ?

[stanlythomas]

Is there any licensing needed to use service worker?

The content is good but the delivery is also very important to keep the audience engaged. It was very flat and made it difficult to continue watching all the way to the end.
