What if not use "shared" in host app about module-federation-examples HOT 1 CLOSED

Sure. So you can choose not to share. But in doing to you'll load multiple copies of the same dependency, a major problem for stuff like react. You only need a import bootstrap if you're sharing something in the entrypoint that's not dynamically imported. If you async imported all the shared modules. Or didn't share, webpack won't have async issues because it's shipping it's own vendors and you're not orchestrating shared code between the apps runtimes. If you added a hook to the remote component. It likely would throw a react error since react needs to be a singleton
