How to dynamically require momentjs locale

Question

Hi Im using expressjs for a backend service in which in need to set the locale for momentjs based on the user browser locale. Im looking for any strategies on how to load the moment/locale/{locale-file based} based on expressjs request.acceptsLanguages.

Any help is greatly appreciated

You can just use a .locale() function after parsing correct language from request (but you have send a language header at least)

const moment = require('moment');
const language = getLanguageFromRequest(req); // or whatever logic you like
moment.locale(language);

but maybe it is better idea to handle it in browser, not in a backend.
