Seen on: TypeScript

Meaning

Use import { x } from "./mod" or add export default x. For CJS libs enable esModuleInterop. Barrel files: export { default as Foo } from "./Foo". Keep a consistent convention (named exports preferred for refactoring).

Common causes

  • Default import of named exports
  • Missing export default
  • Barrel file not re-exporting default
  • CJS interop
  • Renamed export

⚡ Quick fix

  1. import { helper } from "./utils"
  2. Add export default if intended
  3. Re-export defaults in barrels explicitly

Detailed fix by platform

TypeScript

  1. export { default as Button } from "./Button";

How to diagnose

  1. Export — Default?
  2. Import — Matches?
  3. Barrel — Re-exports?
