javascript - use i18n-node in server-side express application -

i can't figure out how should utilize i18n-node module within application.

within views, static texts, it's easy, works but...

here problem :

sometimes have set error messages or else, e.g :

req.flash('message', __('unknown user %s', login));

then i'll have send message views, e.g :

res.render('myview', {message: req.flash('message')});

but first, message "unknown user %s" set in default language json file, , if set "unknown user %s": "something in client language" in client language json file, still display "unknown user myuserlogin".

does have working illustration share ?

edit: , because, there variable in translated string, can't :

res.render('myview', {message: __(req.flash('message'))});

because set "unknown user myuserlogin" in client language json file, instead of "unknown user %s"...

i know question kind of old, ran same issue , found solution.

since using flash method req object, should utilize __ method available in same object:

req.flash('message', req.__('unknown user %s', login));

this way it's gonna translated using current locale of request.
