ESM Import Error

[rlee1990]

I keep getting the below error when trying to use this package with Deno via ESM.SH.

/* esm.sh - error */
throw new Error("[esm.sh] " + "parseCJSModuleExports: Can't resolve 'ws' in '/tmp/esm-build-22c48223b295c5ba9976ebd601dab8cc371bc315-87cf645d/node_modules/isomorphic-ws'");
export default null;

@rlee1990 Can you provide a simple repo to present this error?

[rlee1990]

@heineiuo there is no repo because it won't compile. You can just type ram.sh/ the package name in the web browser and you will see the error

It looks like esm.sh does not respect peerDependencies or there maybe some arguments to support peerDependencies.

Any way to get around this or to get it all working?

Any update @heineiuo

apparently due to the fact that the library does not have an exported file for esm and an error occurs

To address this problem:

1. create an ESM compatible version node.mjs file:

"use strict";

export * from 'ws';

2. Update the package.json file to replace:

  "browser": "browser.js",

with:

  "exports": {
    "browser": "./browser.js",
    "import": "./node.mjs",
    "require": "./node.js"
  },

then add the new node.mjs file in the "files" section.
