websocket-polyfill

WebSocket-Polyfill

Deprecated

This package had been developed very long time ago.

It had utilized the websocket library, but the polyfill could be just done by only one line with ws library. In such reason, websocket-polyfill no more keeps long line of codes, but just have only one line like below.

I think instead of importing this websocket-polyfill library, it would better to write the one line code by yourself.

import import2 from "import2"; // JUST TO AVOID TRANSPILING
import { is_node } from "tstl"; // YOU CAN REPLACE IT LIKE BELOW

// let is_node_: boolean | null = null;
// const is_node = (): boolean =>
//   (is_node_ ??=
//     typeof global === "object" &&
//     typeof global.process === "object" &&
//     typeof global.process.versions === "object" &&
//     typeof global.process.versions.node !== "undefined");

if (is_node()) (global as any).WebSocket ??= import2("ws");
