Code splitting/react-loadable issue

I'm trying to introduce code splitting into my app using react-loadable. I tried it on a very simple component:

const LoadableComponent = Loadable({
    loader: () => import('components/Shared/Logo/Logo'),
    loading: <div>loading</div>,
});

However, when this component is rendered, I get the following error:

Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: object.

Check the render method of `LoadableComponent`.
    in LoadableComponent (created by AppHeader)
    in div (created by AppHeader)
    in AppHeader (created by PlainChatApp)
    in div (created by PlainChatApp)
    in PlainChatApp (created by DragDropContext(PlainChatApp))
    in DragDropContext(PlainChatApp) (created by Connect(DragDropContext(PlainChatApp)))
    in Connect(DragDropContext(PlainChatApp))
    in Provider
    in AppContainer
    in ErrorBoundary

The above error occurred in the <LoadableComponent> component:
    in LoadableComponent (created by AppHeader)
    in div (created by AppHeader)
    in AppHeader (created by PlainChatApp)
    in div (created by PlainChatApp)
    in PlainChatApp (created by DragDropContext(PlainChatApp))
    in DragDropContext(PlainChatApp) (created by Connect(DragDropContext(PlainChatApp)))
    in Connect(DragDropContext(PlainChatApp))
    in Provider
    in AppContainer
    in ErrorBoundary

I don't see anything obvious that I'm doing wrong, and I'm unable to file an issue in that repo.

Solution

  • Turns out that you need to pass a component to the loading option and not JSX. The documentation clearly says this, I just missed it.
