Module.exports and es6 Import
export { Tiger }
would be equivalent to module.exports.Tiger = Tiger
.
Conversely, module.exports = Tiger
would be equivalent to export default Tiger
.
So when you use module.exports = Tiger
and then attempt import { Tiger } from './animals'
you're effectively asking for Tiger.Tiger
.
If you would like to import:
module.exports = Tiger
you may use following construction:
import * as Tiger from './animals'
Then it will work.
Another option is changing the export as described by @Matt Molnar but it is only possible if you are the author of the imported code.
When module.exports
is not set it points to an empty object ({}
). When you do module.exports = Tiger
, you are telling the runtime the object being exported from that module is the Tiger
object (instead of the default {}
), which in this case is a function.
Since you want to import that same function, the way to import is using the default import (import tiger from './tiger'
). Otherwise, if you want to use named import (import { tiger } from './tiger'
) you must change the module.exports
object or use export
keyword instead of module.exports
object.
Default import/export:
// tiger.jsmodule.exports = tiger;// orexport default function tiger() { ... }// animal.jsimport tiger from './tiger';
Named import/export:
// tiger.jsmodule.exports = { tiger };// ormodule.exports.tiger = tiger// orexport const tiger = () => { ... }// orexport function tiger() => { ... }// animal.jsimport { tiger } from './tiger';
