```

### Browser `<script>` tag

Loading this module through a script tag will make it's exports available as `Libp2pKadDht` in the global namespace.

```html
<script src="https://unpkg.com/@libp2p/kad-dht/dist/index.min.js"></script>
```

```sh
> npm i @libp2p/kad-dht
```

### Use in Node.js

```

## API

See <https://libp2p.github.io/js-libp2p-kad-dht> for the auto generated docs.

The libp2p-kad-dht module offers 3 APIs: Peer Routing, Content Routing and Peer Discovery.

### Custom secondary DHT in libp2p

```js
import { createLibp2pNode } from 'libp2p'
import { kadDHT } from '@libp2p/kad-dht'

const node = await createLibp2pNode({
  dht: kadDHT()
  //... other config
})
await node.start()

for await (const event of node.dht.findPeer(node.peerId)) {
  console.info(event)
}
```

Note that you may want to supply your own peer discovery function and datastore
