# Direct WebRTC connection for Waku Relay
|
||||
|
||||
**Demonstrates**:
|
||||
|
||||
- Waku Relay node with direct WebRTC connection
|
||||
- Pure Javascript/HTML.
|
||||
|
||||
This example uses WebRTC transport and Waku Relay to exchange messages.
|
||||
|
||||
To test the example run `npm install` and then `npm start`.
|
||||
|
||||
The `master` branch's HEAD is deployed at https://examples.waku.org/relay-direct-chat/.
|
||||
|
||||
### Steps to run an example:
|
||||
1. Get a Waku node that implements `/libp2p/circuit/relay/0.2.0/hop` and `/libp2p/circuit/relay/0.2.0/stop`
|
||||
1.1. Find `go-waku` node or
|
||||
1.2. Build and then run `go-waku` node with following command: `./build/waku --ws true --relay true --circuit-relay true`
|
||||
2. Copy node's multiaddr (e.g `/ip4/192.168.0.101/tcp/60001/ws/p2p/16Uiu2HAm9w2xeDWFJm5eeGLZfJdaPtkNatQD1xrzK5EFWSeXdFvu`)
|
||||
3. In `relay-chat` example's folder run `npm install` and then `npm start`
|
||||
4. Use `go-waku`'s multiaddr for **Remote node multiaddr** and press dial. Repeat in two more tabs.
|
||||
5. In `tab2` copy **Local Peer Id** and use as **WebRTC Peer** in `tab1` and press dial.
|
||||
6. In `tab1` or `tab2` press **Ensure WebRTC Relay connection**
|
||||
7. In `tab1` press **Drop non WebRTC connections**
|
||||
8. In `tab1` enter **Nickname** and **Message** and send.
|
||||
9. See the message in `tab3` which was connected only to `go-waku` node.
