JS Library from forum's assets folder does not always load

010101

Although I believe it is not the preferred way, I still have a few extensions that load a JavaScript file from the forum's/extension's assets folder. In the past this worked fine.

It seems with newer versions of Flarum, you can refresh your browser multiple times and sometimes the JS file from the public assets folder doesn't load.

I'm not submitting a GitHub issue yet until there's some discussion around this to be sure.

Here's a recording/gif. What you see below is I refresh the page and there is a 404 error in my console saying it can't load a JS file in an extension's assets folder. Then I refresh a few times, and same issue. BUT, I scroll to the top of the site, and then refresh, and MAGIC, the JS file loads.

The files in assets should only be copied/updated when the extension is enabled, or when running the dedicated SSH command.

Debug mode shouldn't have any impact on this.

If the file sometimes return a 404 error it must be something to do with the webserver because Flarum is not touching those files at all during regular page load.

If you click on the URL given in the 404 error, does it successfully show the file? Or are there times where multiple successive requests will all return 404? Do you see the file disappear on disk?

I'm not able to read the actual error message in your GIF so maybe there's something I'm missing.

This happens on my local machine. And a webserver.

If you click on it in the console it of course says the file cannot be found. But, scroll to the top of the page, refresh, and it is found.

I guess it was something to do with the JavaScript in this one extension itself. I think.

So, this is resolved. 🙂

Never mind I think this could is still an issue. Any extension that uses the public assets folder experiences more issues than it once did. It is common to see 404 errors for files that are still in the assets folder. This has happened with extensions I've made, and now I notice it with the PWA app.

Could the core devs look into this one day just to make sure? 🙂

Below you see 404s, but the file exists and is in the same public assets folder where it always has been:

Possibly related: Does Flarum have more lazy loading type features than it once did? I do notice as I scroll "waiting on response" type messages in Chrome.

Edit: Maybe it's Cloudflare stuff. Ugh, there's so many factors and things it could be. 😂🙈
