list of InPortal's

Question

I'm trying to use react-reverse-portal for an infinite scroller (to cache expensive components). So far so good.

For conciseness, I generate a list of InPortals to activate them, and keep them up to date - without a div wrapper for each.

1. Is this risking a memory leak, or does react clean out InPortals not included in a list iteration?

2. Is there a way to include the key argument ( ReactDOM.createPortal(children, container, key ) using InPortal? I'm presuming this would help react maintain a clean list of active portals

Answer 1

没关系，这只是向 InPortal 组件添加一个key属性的问题。
