PWA not available

[benmccann]

I've seen numerous references that PhotoPrism is a PWA. However, I cannot install it when I visit https://demo.photoprism.org. There does not appear to be a service worker available and I think that's why. I'm not sure if this is a feature that hasn't been developed and launched yet or the service worker broke somehow

We don't use service workers at the moment, but there is a manifest.json and you can just add it to your home screen (we plan to add a dialog for this later, so that the feature is more visible):

Ah, okay. I think it's technically not a PWA without a service worker, so I was confused by the use of that term. But I did find the "Add to Home screen" button on mobile and that works for me. Thanks for the clarification!

[lastzero]

Not that I am aware of. We can add a worker later, if that helps.

@benmccann Just added a service worker for you 💐

I get the install prompt in Chrome now, which is kind of cool. Screenshot attached

You're welcome!

I don't have the install prompt. Also in the Chrome menu I still see "Add to Home Screen" as opposed to "Install App".

I have forced stopped Chrome, emptied cache and reloaded the Photoprism page but did not help.

Are you loading photoprism via https using a valid certificate?

[Sherlock1979]

Yes. Nginx reverse proxy using let's encrypt certificate. (Talking to Photoprism through http.)

@Sherlock1979 Still having issues? Maybe clearing the cache helps:

On Desktop, the manifest is not automatically updated, but this is planned for a future update.

I came across this issue while trying to figure out why I couldn't install the PWA. For me, putting the server behind Caddy and setting up HTTPS was enough to make the "Install" button to appear in Firefox and Chrome's menus.

The information at https://docs.photoprism.app/user-guide/pwa#__tabbed_1_2 is slightly wrong - it says "Click Add to Home screen" to install the PWA. This actually just adds a bookmark, which opens in a full browser when tapped. When the criteria for PWA are met, there will be a separate button called "Install" underneath "Add to Home screen" which installs the PWA.
