typescript/no-unnecessary-qualifier Style

💭 This rule requires type information.

What it does

Disallow namespace qualifiers when the referenced name is already in scope.

Why is this bad?

Redundant qualifiers add noise and make type references harder to read.

Examples

Examples of incorrect code for this rule:

namespace A {
  export type B = number;
  const value: A.B = 1;
}

Examples of correct code for this rule:

namespace A {
  export type B = number;
  const value: B = 1;
}

How to use

To enable this rule using the config file or in the CLI, you can use:

Config (.oxlintrc.json)

{
  "options": {
    "typeAware": true
  },
  "rules": {
    "typescript/no-unnecessary-qualifier": "error"
  }
}

Config (oxlint.config.ts)

import { defineConfig } from "oxlint";

export default defineConfig({
  options: { typeAware: true },
  rules: {
    "typescript/no-unnecessary-qualifier": "error",
  },
});

CLI

oxlint --type-aware --deny typescript/no-unnecessary-qualifier
