Set locale for dates formatting globally

[cjoecker]

date-fns has the function setDefaultOptions to set the locale globally. This safe the effort for passing the locale to every format function in order to get the date in the users locale.

Is there a way to use the setDefaultOptions using the i18next locale so that there are no hydration errors if the server has a different locale than the client?

You could do it in your loaders, but note that unless you're 100% sure every request will create a new instance of your server app, your server may be shared between users with different locales, so setting something like this globally will most likely cause issues.

I recommend you to set it on every place you need it or use something like AsyncLocalStorage to make it available to nested code.
