Safe usage of the templates feature

[lewoudar]

Hi folks,
I'm learning how to use the templates feature with an internationalized application. I found this brilliant little project starlettte-i18n and its example.

But now I'm wondering if it is necessary to instantiate the templates object for every request (performance issue?) or if I can define a module with the templates object and used it in every module with route handlers. For the second suggestion I wonder if I would have any concurrency issue since I need to call a method get_locale which lookup a Contextvar variable.

I'd be happy to have some advice on it 🙂
