unicorn/no-anonymous-default-export Restriction

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 in the CLI or using the config file, you can use:

CLI

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

Config (.oxlintrc.json)

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