@anderson.faro typically if you’re doing 12 factor with a microframework, you might also need separate libs for:
1. converting runtime ENV variables to system config - see cfg4k, configur8, konfig etc
2. Performance/metrics implementation - lots of options depending on your needs - (e.g http4k uses a plugin model for micrometer which then backs onto lots of other systems)
3. Events/logging implementation - once again, lots of options - but the core ideal is to use biz events instead of random logging and then plug that into a reporter backend
4. Not strictly required, but we find that a distributed tracing option is invaluable. Zipkin/opentracing etc.
5. Templating - if you’re doing web.
All these should be simple to plugin in your chosen stack without requiring a dependency tree containing 200 different JAR files 😀
