API

offline([opts], fn())

Function that wraps the choo start and use methods, only needed for this plugin, other plugins can be registered before. It can take two parameters.

opts

Type: Object

Optional configuration object for the plugin, can take the following options:

• serviceWorker (String): A string with the relative path to a service worker file, if not provided, it will not install a service worker. Defaults: ''.
• dbConfig (Object): An object with localforage config.

fn

Type: Function

Required function that get as the only argument, the offline plugin object. The object use the following hooks:

• onStateChange: To update the app state locally with localforage.

• onAction: To check if the app is offline and, if it is, use a backup action. Use the backup function when you have actions that depend on network availability, just define a _backup option in your send() data, the _backup option must be a string calling an effect or reducer from your model. For example

     send('xhrEffect', { foo: bar, _backup: 'nonXhrBackup' })

  The above statement will call xhrEffect normally, but when offline, it will call the nonXhrBackup effect|reducer, passing the same data, excluding the _backup strings.

• wrapInitialState: To get the initial local state.
