site only loads when I update the service worker

[yankeeinlondon]

possibly this problem is isolated but 2-3 times this past week i've been unable to load the site. Well it loads but only some really awkward framing (and no I didn't take a screenshot ... damn). When I'm in this state I can hit reload to my hearts content but it never gets out of this bad state. I had a suspicion that it was to do with the service worker and so I explictly went into the devtools and hit "update" ... immediately all is well again.

The first time I did this I figured I -- or at least my browser -- must have been at fault but as I say it has happened 2 or 3 times in the past week so I'm starting to think there's something a bit off with the service worker.

Feel free to close this if you like ... I'm afraid I can't give you steps to reproduce ... but I did want to give a heads up in case it was helpful.

Aha! I actually reproduced it and it was a bit too easy. I shut down the working tab on my browser (Chrome, macOS, v74) and then cut and pasted the URL back into a new tab:

Here's a video of me:

• starting in "bad place"
• bringing up devtools
• pressing "update" (for service worker)
• after the update I press CMD+R and it reloads fine

Also note the cascade of errors loading js assets prior to the update/reload
