How to do routing for localization on Node.js and Express.js?

Question

Internationalization and localization

All health!
The essence of the problem is as follows.
The site uses some default language, such as English. To switch to another language, for example, Russian, the paths should be: http://site.com/ru/some-path. How to configure routing to render the same templates with different languages ​​for routes:
site.com/some-path
site.com/ru/some-path
Added a prototype of what I want to do

Is this good practice or could it be better?
