Version 2.0.1 is missing the check for window object in provider js file

[khaled-hamam]

I'm using the library with next.js as a server side rendering framework, and I found that there was unintended behavior happens as the socket is created in server side although it shouldn't due to this line:

// src/io/provider.ts
if (!window) {
  return <>{children}</>;
}

I found that the built js file didn't have this check, so I cloned the project, and run a build, and somehow that was the only line that didn't make it in the previous build (also package-lock version is on 1.0.1 if this matters).

Before Build (current state)

// lib/io/provider.js
var url = _a.url, opts = _a.opts, children = _a.children;
var socketRef = react_1.useRef();

After Build

var url = _a.url, opts = _a.opts, children = _a.children;
if (!window) {
  return react_1["default"].createElement(react_1["default"].Fragment, null, children);
}
var socketRef = react_1.useRef();
