Rule Details

This rule aims to let users know when a namespace or enum qualifier is unnecessary, whether used for a type or for a value.

Examples of code for this rule:

❌ Incorrect

namespace A {
  export type B = number;
  const x: A.B = 3;
}

namespace A {
  export const x = 3;
  export const y = A.x;
}

enum A {
  B,
  C = A.B,
}

namespace A {
  export namespace B {
    export type T = number;
    const x: A.B.T = 3;
  }
}

✅ Correct

namespace X {
  export type T = number;
}

namespace Y {
  export const x: X.T = 3;
}

enum A {
  X,
  Y,
}

enum B {
  Z = A.X,
}

namespace X {
  export type T = number;
  namespace Y {
    type T = string;
    const x: X.T = 0;
  }
}

Options

// .eslintrc.json
{
  "rules": {
    "@typescript-eslint/no-unnecessary-qualifier": "warn"
  }
}

This rule is not configurable.
