Named export 'OAuth' not found

[humbird0]

I tried to run the example for generating and Authorization URL, but Node JS failed with this error.

import generator, { OAuth } from 'megalodon'
                    ^^^^^
SyntaxError: Named export 'OAuth' not found. The requested module 'megalodon' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from 'megalodon';
const { OAuth } = pkg;

Node.js v22.11.0

What I did:

1. I installed the latest version of Node JS in Windows 10, using its MSI installer.
2. In a folder on my hard drive, I opened a command prompt and typed: npm install megalodon
3. I logged into a mastodon instance and used Firefox's dev tools to find the clientid and the clientsecret from the "Storage" tab and "Indexed DB" section.
4. I created a file called "register_application.js" and pasted the 1st example code under the "Authorization" section of your readme.
5. I modified the BASE_URL, clientId, and clientSecret with the values from the web dev tools. (actual values redacted for privacy)
   const BASE_URL = 'https://mymastodon.website'
   let clientId = "xxxxxxxxxx"
   let clientSecret = "yyyyyyyyy"
6. I created a CMD file containing:

node register_application.js
pause

7. When I ran this CMD file, the error occurred.

Which part did I do wrong?

It seems like commonjs and esm problems. Do you have package.json?

[humbird0]

Yes. package.json looks like this:

{
  "name": "to_mastodon",
  "version": "1.0.0",
  "description": "Post things to mastodon",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "humbird0",
  "license": "CC0-1.0",
  "dependencies": {
    "express": "^4.21.1",
    "mastodon": "^1.2.2",
    "mastodon-api": "^1.3.0",
    "open": "^8.4.0"
  }
}

Incidentally, inside the package-lock.json file. mastodon-api lists oauth as a dependency.

"node_modules/mastodon-api": {
      "version": "1.3.0",
      "resolved": "https://registry.npmjs.org/mastodon-api/-/mastodon-api-1.3.0.tgz",

      "dependencies": {

    },

Are you using mastodon-api?
This package.json looks like you don't use megalodon.
