If by coding style, you mean conventions and not design patterns, then I'm surprised no one has mentioned the official documentation nor the standard library of sorts. I'm relatively new in the industry but at least I'm quick to realize that every language/framework community tend to have their own preferred style; not a one-size-fits-all thing. And these preferences are usually set off by code samples from the official docs. This is true at least for the big communities where the official docs are well-written.
