choo-service-worker

Service worker loader for choo. Only runs in the browser, and emits events. Does not include the worker code itself, you'll need to serve it using a tool like bankai.

Usage

var choo = require('choo')

var app = choo()
if (process.env.NODE_ENV !== 'production') {
  app.use(require('choo-service-worker/clear')())
}
app.use(require('choo-service-worker')())
app.mount('body')

The above example will install your service worker, and add the events and state properties documented below. For a complete example on how to use them check the example.js file.

API

plugin = sw([route], [opts])

Register a new service worker if possible. Route defaults to /sw.js. An optional opts object can be passed, you can add a electron Boolean property to the options object, to enable registration in electron, the rest of the options are passed directly to the registration method of the service worker. Note that, if you enable electron with opts.electron, the scope property will be forced to the root path of your app. Emits events when the worker is registered. The plugin also add a few properties to the app state.

• state.syncTags: array - an array of registered tags for background syncronization.

clear = sw/clear()

Clear all service workers.
