Description
An empty interface is equivalent to its supertype. If the interface does not implement a supertype, then the interface is equivalent to an empty object ({}). In both cases it can be omitted.
Bad Practice
// an empty interface
interface Foo {}
// an interface with only one supertype (Bar === Foo)
interface Bar extends Foo {}
// an interface with an empty list of supertypes
interface Baz {}
Recommended
// an interface with any number of members
interface Foo {
name: string;
}
// same as above
interface Bar {
age: number;
}
// an interface with more than one supertype
// in this case the interface can be used as a replacement of a union type.
interface Baz extends Foo, Bar {}
