Description Samuel Padgett 2021-02-10 13:54:23 UTC

Console supports English messages using the `en` language only. We don't have separate messages for locales like `en-US` and `en-GB`. Currently, the way i18next is configured, console tries to get the `en-US` messages first, which causes dozens of 404 network requests. It doesn't result in any user-visible errors, but it slows down console load, particularly since browser limit how many requests can be made in parallel. This can slow down console load by more than a second in some cases.

We should configure i18next to use the language-only when requesting a namespace to avoid the unnecessary requests.

Checked on ocp 4.8 cluster with payload 4.8.0-0.nightly-2021-02-19-111007.
Login in console, open developer console by click F12, check the console log, there is no "en-US" requesting message shown.
@Sam, not sure if it's correct to check developer console log to verify this bug, could you give some suggestions？

Comment 3 Samuel Padgett 2021-02-20 20:49:42 UTC

That's the right way to verify. If the bug wasn't fixed, you'd see many 404 Not Found messages for en-US JSON files.

Thanks, Sam!
Checked again on ocp 4.8 cluster with payload 4.8.0-0.nightly-2021-02-21-102854. on console there is no 404 Not Found message for en-US JSON files now, the bug is fixed.
