What is the purpose of the single responsibility principle (SRP) applied to Node.js route handlers?

Accepted Answer

The single responsibility principle (SRP) applied to Node.js route handlers ensures that handlers only parse the HTTP request and delegate business logic to service layers. This separation keeps handlers thin and allows for independent testing of business logic.
