Switch to default locale instead of throwing an error in case of non-existing locale;

Hi,

Thanks for this embla plugin.

When using it I've stumbled upon an error being thrown on module initializing.
If the locale does not exist in the translations files, the plugin throws an error and it's preventing the carousel from initializing.

embla-carousel-aria/src/plugins/aria.ts

Line 55 in 8589d71

intl = getIntl(options.locale);

Would you be open to be merging a pr that prevent the module from crashing when the locale does not exist in the resource of the module and uses the default language (en-US) ?

Regards

Hi !
Any chance looking at the pr ?

Hey, sorry for the delay, I was pretty busy the last 3 weeks.

Could you share more on which locales are missing or why you need support for arbitrary strings?

The library is currently throwing because it can't make good assumptions about the default locale to fallback to, so it shifts the burden of that to the developer, who should know much more about the user preferences/target audience.

Hi,

No problem ! The locale handling is a vast subject and I understand the fact that you choose not to make assumptions on the matter.

I had an issue with one french locale. While the fr-FR locale is present, I tried with the fr-BE (quite close but not the same) and the module crashed.

I didn't found a way to check if the user locale has a matching locale file in the module before instanciating the plugin.

The proposed PR is a quick fix to ensure that the module doesn't prevent the carousel to initialize if the user locale is not found in the existing ones.
I thought of adding an option to set a fallback locale but it seemed simpler to use the locale from the module default options.
I agree with you on the fact that the developper should be handling the part about the user locale. That being said, it could be usefull to expose the available languages to make the check easier.
