Should I write a REST API manually?

Question

API

Good day.
How do you write a REST API? Is it all manual, or do you use different tools for this?
For example, Node.js has Loopback.io, with it in a couple of commands you can create a REST API, with user authorization and other goodies.
Ps We are not talking about experience, please give an answer based purely on efficiency and further problems / benefits.

Answer 1

Everything that is more complicated than CRUD (now or in the future) should be written by hand, unless controllers can be generated (for example, according to the API documentation if it is in some common format, such as api blueprint, RAML, etc.).
