nostr:npub1zuuajd7u3sx8xu92yav9jwxpr839cs0kc3q6t56vd5u9q033xmhsk6c2uc I'm clearly missing something simple here. Can't find any example that uses NDKPrivateKeySigner either.
```
import NDK, {
NDKEvent,
NDKFilter,
NDKPrivateKeySigner,
} from "@nostr-dev-kit/ndk";
const signer = NDKPrivateKeySigner.generate();
console.log(signer);
const ndk = new NDK({
explicitRelayUrls: ["wss://relay.damus.io", "wss://relay.nostr.band"],
signer: signer,
});
const ndkEvent = new NDKEvent(ndk);
ndkEvent.kind = 1;
ndkEvent.content = "Hello, world!";
ndkEvent.created_at = Math.floor(Date.now() / 1000);
ndk.connect().then(() => {
ndkEvent.publish().then(() => {
console.log("Event published!");
});
});
```
```

hmm, that looks ok at first glance; I’ll copy the code and run it, there must be something obvious
Worth trying, right after creating the signer:
signer.user().then(console.log)
there’s gotta be something going on instantiating the signer; in what environment is this running?
pnpm and I'm running Fedora.
but are you running in a browser? node?
Yes using node.
I'm going to guess you are missing a websocket-polyfill
I just literally copied your code without changing a thing and it just published nevent1qgspdq8u9akd245y7u5hxtthvcsjd4g54uzcrp7dnlx9ehxyfgyyj0cpzamhxue69uhhyetvv9ujumn0wd68ytnzv9hxgtcpz4mhxue69uhhyetvv9ujuerpd46hxtnfduhsqg9acv82a30e0v6lkhf05f7rmjzhaxnxa7v86y6asa2k6d7s6g4q5uu639fp
make sure to import "websocket-polyfill" if you are running a nodejs environment
Getting an errror from the import, even from a new project
pnpm install --save websocket-polyfill
```
import "websocket-polyfill"
```
npx esrun test.ts
```
/home/user/Documents/Programming/upload/node_modules/.pnpm/websocket-polyfill@1.0.0_bufferutil@4.0.8_utf-8-validate@5.0.10/node_modules/websocket-polyfill/lib/index.js:8

completely forgot about the websocket-polyfill, removed from the nostr-tools readme. Now recommends this:
``
import { useFetchImplementation } from 'nostr-tools/nip05'
useFetchImplementation(require('node-fetch'))
``
Adding that to ndk fixed it. Thanks!
```
import { useWebSocketImplementation } from 'nostr-tools/pool'
// or import { useWebSocketImplementation } from 'nostr-tools/relay' if you're using the Relay directly
import WebSocket from 'ws'
useWebSocketImplementation(WebSocket)
```
copied wrong snippet.
