```console
$ npm i @libp2p/delegated-content-routing
```

### Browser `<script>` tag

Loading this module through a script tag will make it's exports available as `Libp2pDelegatedContentRouting` in the global namespace.

```html

```

Leverage other peers in the network to perform Content Routing calls.

Requires access to `/api/v0/dht/findprovs` and `/api/v0/refs` HTTP API endpoints of the delegate node.

## Requirements

`@libp2p/delegated-content-routing` leverages the `kubo-rpc-client` library and requires an instance of it as a constructor argument.

```sh
npm install kubo-rpc-client @libp2p/delegated-content-routing
```

## Example

```js
import { createLibp2p } from 'libp2p'
import { delegatedContentRouting } from '@libp2p/delegated-content-routing'
import { create as createIpfsHttpClient } from 'kubo-rpc-client'

// default is to use ipfs.io
const client = createIpfsHttpClient({
  // use default api settings
  protocol: 'https',
  port: 443,
  host: 'node0.delegate.ipfs.io'
})

const node = await createLibp2p({
  peerRouting: [
    delegatedContentRouting(client)
  ]
  //.. other config
})
await node.start()

for await (const provider of node.contentRouting.findProviders('cid')) {
  console.log('provider', provider)
}
```
