export-default-identifier

An eslint plugin that only allows export default to export specific types of expressions.

By default, only allows Identifier expressions, i.e. named variables. Excludes all anonymous classes, functions, and objects. This was originally created for use with TypeDoc, which does not generate proper JSDOC documentation for anonymous export defaults.

NOTE: Equivalent to import/no-anonymous-default-export:

"import/no-anonymous-default-export": ["error", {
  "allowArray": false,
  "allowArrowFunction": false,
  "allowAnonymousClass": false,
  "allowAnonymousFunction": false,
  "allowCallExpression": false,
  "allowLiteral": false,
  "allowObject": false
}]

Install

npm install --save-dev export-default-identifier

Usage

Add to your .eslintrc.json:

{
  "plugins": [
    "export-default-identifier",
  ],
  ...
  "rules": {
    "export-default-identifier/export-default-identifier": "error"
  }
}

Specify exactly which types can be exported as default:

"export-default-identifier/export-default-identifier": ["error", {
  "types": ["Identifier"]
}]
