I like Echo (echo.labstack.com) a lot. Nice and modular, more capable than Gin with about the same performance, and I think it meets all of your criteria (except having never used Spring Boot before, I don't know how it compares). - Dave > On May 9, 2020, at 12:39 AM, Sai Matam wrote: > > W

Don't be afraid of the term "senior". The process prior to signing a contract is mutual application. The company advertises itself like the candidate advertises himself.

Dan: I don't know why you are talking about "named type". The nomenclature is outdated and obsoleted by "defined type". The only reason I see to still use it is so you can make an argument that "it has a name" means "it's a defined type" - which isn't even a correct argument anymore since type ali

In https://golang.org/ref/spec#Types a Type is defined in terms of a TypeName a TypeLit or a (Type). A TypeName is what makes a type a named type. This is defined as either an identifier or a qualified identifier. For the discussion here we can ignore the latter. An identifier contains letters and
