Setting the language - server-side / client-side

[danlong]

Is there a way to set the NodeBB language in either the server or client js?

I have a cookie that contains the language code I want to set the forum to.

Is there a hook I can use on the server-side to set the language, or equally something on the client side I can use to change the locale?

Is there a way I can hook into the User's 'language' selector options to roll my own solution?

Note: passing ?lang=[LANGAUGE] in the URL isn't an option
Note: Using the User settings isn't an option as I need to set the language before this point, from a Cookie

Is there a way to read cookies in the middleware.autoLocale function? (src/middleware/headers.js) req.cookies = {} at this point.
However, inside the function translate(str, req, res, next) { req.cookies is a full object as I expect (src/middleware/render.js)

Thanks!

@danlong you can override the userLang in filter:config.get, BTW notice req.query.lang in there, that's how ?lang= works.

@PitaJ Perfect, thank you. That's done the trick

@PitaJ Does config.userLang set the language for guests? Or is that a different property?

[PitaJ]

@danlong I believe it applies to all users

[danlong]

@PitaJ OK, I'll check it again - it seems to change the timedate for guests, nothing else gets translated. It's only logged-in users which seem to be effected by the config.userLang

Passing the ?lang= for a guest doesn't seem to work either

@PitaJ I think I have a very edge-case scenario, I've found a solution for guests and logged in users.

Thanks for your help and point in the right direction!
