Agree!
Imho it's a bit of an oversight that this hasn't been done before?
And it should be an easy enough change.

I'd love to see that as well :)

It was not an oversight. I tried it before a couple of times, but because the way React-Admin apps are structured, I'd have to add all languages in the final bundle, which would make the initial load larger and slower.

I tried it again and I think I found a good solution. The new config option is DefaultLanguage, and it has to be the 2 letter ISO code for the language (see the list here: https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes) one of the file names in the resources/i18n. Ex for Chinese Simplified it has to be zh-Hanz (case sensitive)

Please test it and let me know.

@deluan tested with latest develop branch ba28e9a.
Works well and as expected.

One thing to add: The new DefaultLanguage setting is case sensitive, only lowercase entries work.
f.e. this works:
DefaultLanguage="pt"
but this doesnt:
DefaultLanguage="PT"

Which is fine, just something to be aware of.

Fixed. Thanks for testing.

Just tested with latest docker hub release 0.48.0, it works fine with this in the docker compose :
ND_DEFAULTLANGUAGE: "fr"
Thank you for this 🍺

Thanks for adding the option. However for "zh-Hans" it occurs error that translation(id:zh-hans) not found.

You has to be 2 letter ISO code for language . The China`s 2 letter is 'zh' ?

Unfortuately, it doesn't define in the resources i18n.
And the author has restore DefaultLanguage case-sensitiveness here.

I tried ND_DEFAULTLANGUAGE = zh, but the default language was not changed to Chinese, and the others were not successfully changed, and the browser was in seamless mode.

[deluan]

The DefaultLanguage option has to match one of the file names in the resources/i18n folder as @SoSolife mentioned. So for Chinese simplified it has to be zh-Hans, and it is case sensitive.

It is only used for new sessions. So, if you already logged from a browser, it won't use the default anymore.
