Is it underlaying express.js dependencies

[alekslyse]

From what I see it doesnt come clear by the documentation; if lamda vs express is options or limited alternatives;

Do I understand correctly its possible to use lambda with reduced builtin functionality, but with using express.js this framwork run as intended with more backend communction between the express.js framework and this framework?

So in other words; If I can use express.js, use express.js, but lamda if I want it to work, but might not fully?

A lambda function using alexa-app is virtually the same as a route in express hosting an alexa-app skill. The only difference is that with express, you have the option of hooking other services or logic into different routes, while lambda functions are designed to handle one thing at a time.
