Rule: no-unnecessary-class

Disallows classes that are not strictly necessary.

Rationale

Users who come from a Java-style OO language may wrap their utility functions in an extra class, instead of putting them at the top level.

Config

Three arguments may be optionally provided:

• "allow-constructor-only" ignores classes whose members are constructors.
• "allow-empty-class" ignores class DemoClass {}.
• "allow-static-only" ignores classes whose members are static.

Config examples

"no-unnecessary-class": true

"no-unnecessary-class": ["allow-empty-class", "allow-constructor-only"]
