In this project, we hope to build a set of reference applications that make full use of service workers.
Our goal is to show how you can perform tasks that are common in native applications using this new set of APIs. We want to keep the apps simple, so they can be easily bisected and copied by anyone.
Sorry about going all caps there, but these are all in the earliest stage of development. We are looking for people to help us create these apps!
Please note that the spec and implementations are in a very early stage! You may find issues with implementations in that they may often change or produce strange results at first. To see what actually works in browses today, see:
- Jake Archibald's IsServiceWorkerReady page - check fo all implementations
The process below is a guideline to how to get started.
- Fork this repo!
- Choose one of the apps from the directories above.
- Use the app's behavior draft to implement the application.
- Keep it really simple! See our list of resources below to learn about service workers.
We will be hosting them on a website soon, so you can see them as we build them.
Right now, you will need:
- Chrome Canary. Type: "chrome://flags/" in the URL bar and turn on "enable-service-worker" and "experimental-web-platform-features".
If you have a more interesting app you want to build, please add them to this repo. Just add a directory to the root directory with a README.md file explaining what the app does and send us a pull request!
