namedDefaultExports

Reports anonymous functions and classes as the default export.

✅ This rule is included in the ts stylisticStrict presets.

Naming default exports improves codebase searchability by ensuring consistent identifier use for a module’s default export, both where it’s declared and where it’s imported.

Anonymous default exports make it harder to search for all usages of a module’s primary export, since consumers can choose any name when importing.

This rule reports anonymous functions and classes that are default exported.

export default function () {
  return "value";
}

export default () => {
  return "value";
};

export default class {
  
default.getValue(): number
getValue() {
    return 42;
  }
}

export default function 
function getValue(): string
getValue() {
  return "value";
}

const 
const getValue: () => string
getValue = () => {
  return "value";
};
export default 
const getValue: () => string
getValue;

export default class 
class Container
Container {
  
Container.getValue(): number
getValue() {
    return 42;
  }
}

const 
const value: 42
value = 42;
export default 
const value: 42
value;

This rule is not configurable.

When Not To Use It

If your project does not rely on consistent naming for default exports, or if you prefer the flexibility of allowing anonymous default exports, you can disable this rule. Some codebases may have established patterns where anonymous default exports are acceptable.
