sw-precache | node module to generate service worker code | Web Framework library

sw-precache is a JavaScript library typically used in Server, Web Framework, Nodejs applications. sw-precache has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

Make sure your site is served using HTTPS! Service worker functionality is only available on pages that are accessed via HTTPS. (will also work, to facilitate testing.) The rationale for this restriction is outlined in the "Prefer Secure Origins For Powerful New Features" document. Incorporate sw-precache into your node-based build script. It should work well with either gulp or Grunt, or other build scripts that run on node. In fact, we've provided examples of both in the demo/ directory. Each build script in demo has a function called writeServiceWorkerFile() that shows how to use the API. Both scripts generate fully-functional JavaScript code that takes care of precaching and fetching all the resources your site needs to function offline. There is also a command-line interface available, for those using alternate build setups. Register the service worker JavaScript. The JavaScript that's generated needs to be registered as the controlling service worker for your pages. This technically only needs to be done from within a top-level "entry" page for your site, since the registration includes a scope which will apply to all pages underneath your top-level page. service-worker-registration.js is a sample script that illustrates the best practices for registering the generated service worker and handling the various lifecycle events.
