adjacent-overload-signatures

Require that member overloads be consecutive.

Grouping overloaded members together can improve readability of the code.

Rule Details​

This rule aims to standardize the way overloaded members are organized.

declare namespace Foo {
  export function foo(s: string): void;
  export function foo(n: number): void;
  export function bar(): void;
  export function foo(sn: string | number): void;
}

type Foo = {
  foo(s: string): void;
  foo(n: number): void;
  bar(): void;
  foo(sn: string | number): void;
};

interface Foo {
  foo(s: string): void;
  foo(n: number): void;
  bar(): void;
  foo(sn: string | number): void;
}

class Foo {
  foo(s: string): void;
  foo(n: number): void;
  bar(): void {}
  foo(sn: string | number): void {}
}

export function foo(s: string): void;
export function foo(n: number): void;
export function bar(): void;
export function foo(sn: string | number): void;
