我在哪里可以找到 Node 的 SignalR 核心 polyfill

Where I can found the SignalR core polyfills for Node

SignalR npm package 中说,为了从 Node 使用我们应该包含一些 polyfills

The following polyfills are required to use the client in Node.js applications:

XmlHttpRequest - always

WebSockets - to use the WebSockets transport

EventSource - to use the ServerSentEvents transport

btoa/atob - to use binary protocols (e.g. MessagePack) over text transports (ServerSentEvents)

问题是,有人 link 那些 polyfill 吗?

供将来参考:

答案好像是here
