# Received and Send messages using Waku Relay
|
|
|
|
|
|
|
|
|
|
Waku Relay is a gossip protocol that enables you to send and receive messages.
|
|
|
|
|
You can find Waku Relay's specifications on [Vac RFC](https://rfc.vac.dev/spec/11/).
|
|
|
|
|
|
|
|
|
|
Before starting, you need to choose a _Content Topic_ for your dApp.
|
|
|
|
|
Check out the [choose a content topic guide](choose-content-topic.md) to learn more about content topics.
|
|
|
|
|
|
|
|
|
|
For the purpose of this guide, we are using a unique content topic: `/relay-guide/1/chat/proto`.

# Installation
|
|
|
|
|
|
|
|
|
|
You can install [js-waku](https://npmjs.com/package/js-waku) using your favorite package manager:
|
|
|
|
|
|
|
|
|
|
```shell
|
|
|
|
|
npm install js-waku
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
# Create Waku instance
|
|
|
|
|
|
|
|
|
|
In order to interact with the Waku network, you first need a Waku instance:
|
|
|
|
|
|
|
|
|
|
```js
|
|
|
|
|
import { Waku } from 'js-waku';
|
|
|
|
|
|
|
|
|
|
const wakuNode = await Waku.create();
|
|
|
|
|
```

# Connect to other peers
|
|
|
|
|
|
|
|
|
|
The Waku instance needs to connect to other peers to communicate with the network.
|
|
|
|
|
You are free to choose any method to bootstrap and DappConnect will ship with new methods in the future.
|
|
|
|
|
|
|
|
|
|
For now, the easiest way is to connect to Status' Waku fleet:
|
|
|
|
|
|
|
|
|
|
```js
|
|
|
|
|
import { getStatusFleetNodes } from 'js-waku';
|
|
|
|
|
|
|
|
|
|
const nodes = await getStatusFleetNodes();
|
|
|
|
|
await Promise.all(nodes.map((addr) => waku.dial(addr)));
|
|
|
|
|
```
|
