/**

|
* A simple, no-op service worker that takes immediate control.
|
|
* Use this file if the active service worker has a bug and we
|
|
* want to deactivate the worker on client browsers while we
|
|
* investigate the problem.
|
|
*
|
|
* To activate this service worker file, rename it to `worker-basic.min.js`
|
|
* and deploy to the hosting. When the original worker files cache
|
|
* expires, this one will take its place. (Browsers ensure that the expiry
|
|
* time is never longer than 24 hours, but the default expiry time on Firebase
|
|
* is 60 mins).
