unicorn/no-anonymous-default-export Restriction

🚧 An auto-fix is planned for this rule, but not implemented at this time.

What it does

Disallows anonymous functions and classes as default exports.

Why is this bad?

Naming default exports improves searchability and ensures consistent identifiers for a module’s default export in both declaration and import.

Examples

Examples of incorrect code for this rule:

export default class {}
export default function () {}
export default () => {};
module.exports = class {};
module.exports = function () {};
module.exports = () => {};

Examples of correct code for this rule:

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;

How to use

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

Config (.oxlintrc.json)

{
  "rules": {
    "unicorn/no-anonymous-default-export": "error"
  }
}

CLI

oxlint --deny unicorn/no-anonymous-default-export
