To increase popularity and attract users it needs to provide more practical examples from real life. Users (me too :) ) like to see additional pros. After using Koa2 and FeathersJS I like the moleculer and I will be happy to see the users number growing.
The second reason is that when I tried to setup this middleware, I couldn't do it just with official swagger-stats manual and google (for FeathersJS all OK, works from half-kick). Because this middleware is not just the "function" but provides own handler with GUI. I hope this small tip will help somebody too.
So, it is not just for more unnecessary examples but small additional tip at the same time.
Use swagger-stats UI for quick look on the "health" of your API (TypeScript)
