Vapor was interesting because it recently built over SwiftNIO, and initial reports of its performance were very positive. A highly performant HTTP application based framework in a memory safe language? Worth a look! I have used dynamically typed languages (NodeJS/TypeScript/Javascript andContinue reading “Vapor 3 and a few random experiments”
