### Version info **Angular:** latest **Firebase:** latest **AngularFire:** latest **Other (e.g. Ionic/Cordova, Node, browser, operating system):** ### How to reproduce these conditions For any project run: ``` ng add @angular/fire ``` If the app is a PWA it'll have `ngsw-config.json`, which firebase will cache for an hour. ### Expected behavior Add the file to the cache ignore list. Thanks to @abraham for mentioning this today on the Modern Web meetup.
