Have you ever made a change that negatively impacted the front-end? Checking one page for a change might be easy. Checking hundreds is difficult and time-consuming. Visual Differ allows you to supply an array of URLs to audit and will create an audit.csv to show which comparisons passed and which ones had a non-trivial difference as defined in your config file. Additionally, you can review the screenshots that were taken and see a "heatmap" of the visual differences thanks to the pixelmatch library.

QUESTION
I have implemented service worker in my web app and attempted to cache all html, css, js, and images file. My hosting service is firebase, after a successful deployment I tested if the service will work and the files will be cached, unfortunately the following error will do occur.
service-worker.js
...ANSWER
Answered 2018-Jul-22 at 21:34Cache.addAll()
is an all or nothing API. If any response is not in the 200 HTTP status code range, nothing will be cached.
cache.addAll will reject if any of the resources fail to cache. This means the service worker will only install if all of the resources in cache.addAll have been cached.
Firebase returns 404 Not Found
for the /404.html
file.
An approach to resolve this is to have a file /notfound.html
like you have and then return that in fetch
when needed.
