Using i18next-node with moment.js

[remoe]

Does anyone know a way to sync the language selection between i18next and moment.js? I mean something like:

app.locals({
  format_date: function(val) {
    moment.lang(i18next.lng());
    return moment(val);
  }
});

It should be automatic switch the language of moment.js when i18n switch to a new language.

Thanks

on clientside this is rather easy. If you don't pass language to init the detected language fill be detected and avaiable when the init call back is called: i18next.lng().

on the serverside the current language is set per request, so grab it from the request object req.lng.

i'm not sure but i think moment itself is a singleton - so setting it's language should be done just before using it (if you got some async stuff inside your route handling - else another request could overwrite the current set language in moment.js resulting in wrong localization).

you might add your own middleware after i18next:

// Configuration
app.configure(function() {
    app.use(i18n.handle);
    app.use(function(req, res, next) {
        res.locals.format_date: function(val) {
           moment.lang(req.lng);
           return moment(val);
        }
    });
});

Thanks for this hint. I use the following:

app.use(i18next.handle);

app.use(function(req,res,next){
  res.locals.format = {
    date: function(val) {
      moment.lang(req.lng);
      return moment(val).format("L LT");
    }
  };
  next();
});
