Disallow anonymous functions and classes as the default export

💼 This rule is enabled in the ✅ recommended config.

💡 This rule is manually fixable by editor suggestions.

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.

Fail

export default class {}

export default function () {}

export default () => {};

module.exports = class {};

module.exports = function () {};

module.exports = () => {};

Pass

export default class Foo {}

export default function foo () {}

const foo = () => {};
export default foo;

module.exports = class Foo {};

module.exports = function foo () {};

const foo = () => {};
module.exports = foo;
