I'm not sure how valuable this type of thing really is. Templates tend to fall out of date, since they're not actively used, they're not actively updated to new practices. I've seen this with lots of templates in other languages.
The libraries having excellent documentation and pointing to apps that are similarly implemented tends to be better maintained, IMO.
For example one for creating a microservice complete with routes, test cases, JSON support etc. Another for a command line application.
In languages with a steeper learning curve like Rust there needs to be more of an opinionated approach to teaching users.
