@ -7,6 +7,13 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
## [Unreleased]
### Added
- New `bootstrap` option for `Waku.create` to easily connect to Waku nodes upon start up.
### Changed
- Renamed `discover.getStatusFleetNodes` to `discovery.getBootstrapNodes`;
Changed the API to allow retrieval of bootstrap nodes from other sources.
### Removed
- Examples (cli-chat): The focus of this library is Web environment;
Several examples now cover usage of Waku Relay and Waku Store making cli-chat example obsolete;

```ts
// Directly dial a new peer
await waku.dial('/dns4/node-01.do-ams3.wakuv2.test.statusim.net/tcp/443/wss/p2p/16Uiu2HAmPLe7Mzm8TsYUubgCAW1aJoeFScxrLj8ppHFivPo97bUZ');

['/dns4/node-01.do-ams3.wakuv2.test.statusim.net/tcp/443/wss']
);
```
You can also use `getStatusFleetNodes` to connect to nodes run by Status:
```ts
import { getStatusFleetNodes } from 'js-waku';
getStatusFleetNodes().then((nodes) => {
nodes.forEach((addr) => {
waku.dial(addr);
});
});
const waku = await Waku.create({ bootstrap: true });
```

The Waku instance needs to connect to other peers to communicate with the network.
You are free to choose other methods to bootstrap and DappConnect will ship with new bootstrap mechanisms in the future.
For now, the easiest way is to connect to Status' Waku fleet:
Passing the `bootstrap` option will connect your node to predefined Waku nodes.
