Koajd has the same problem Express.js has, its batteries&#x2F;middleware are not Omakase first class but third party. So I expect friction as things move forward in terms of updates. Ever dealt with RubyGems when upgrading Rails?<p>Imagine if your core app consisted of all different third party libs and you wanna update Express&#x2F;Koa?<p>Then we have typedefinitions for all those libraries. Which why I&#x27;m looking for alternatives with typed languages.<p>You might have misunderstood my question or I&#x27;m getting things wrong again.  :-)
