How handle optional prefix in routes

[Bloomca]

Hi!

I have a problem – I have an optional prefix for any route which looks like "/ca/en/english".
But I have to parse it and treat only if it will succeed my regex (something like //[a-z]{2]/[a-z]{2}/[^/]+//). So, what is the best approach to make it possible with react router?

I saw this one, but, to be honest, this approach seems like the invention of my own router.

Any ideas?

Thanks!
