# Configure websocket transport
|
||
|
|
|
||
|
|
Websocket is currently the only Waku transport supported by browser nodes using [js-waku](https://github.com/status-im/js-waku).
|
||
|
|
Setting up websocket enables your node to directly serve browser peers.
|
||
|
|
|
||
|
|
A valid certificate is necessary to serve browser nodes,
|
||
|
|
you can use [`letsencrypt`](https://letsencrypt.org/):
|
||
|
|
|
||
|
|
```shell
|
||
|
|
sudo letsencrypt -d <your.domain.name>
|
||
|
|
```
|
||
|
|
|
||
|
|
You will need the `privkey.pem` and `fullchain.pem` files.
|
||
|
|
|
||
|
|
To enable secure websocket, pass the generated files to `wakunode2`:
|
||
|
|
Note, the default port for websocket is 8000.
|
||
|
|
|
||
|
|
```shell
|
||
|
|
wakunode2 --websocket-secure-support=true --websocket-secure-key-path="<letsencrypt cert dir>/privkey.pem" --websocket-secure-cert-path="<letsencrypt cert dir>/fullchain.pem"
|
||
|
|
```
|
||
|
|
|
||
|
|
## Self-signed certificates
|
||
|
|
|
||
|
|
Self-signed certificates are not recommended for production setups because:
|
||
|
|
|
||
|
|
- Browsers do not accept self-signed certificates
|
||
|
|
- Browsers do not display an error when rejecting a certificate for websocket.
|
||
|
|
|
||
|
|
However, they can be used for local testing purposes:
|
||
|
|
|
||
|
|
```shell
|
||
|
|
mkdir -p ./ssl_dir/
|
||
|
|
openssl req -x509 -newkey rsa:4096 -keyout ./ssl_dir/key.pem -out ./ssl_dir/cert.pem -sha256 -nodes
|
||
|
|
wakunode2 --websocket-secure-support=true --websocket-secure-key-path="./ssl_dir/key.pem" --websocket-secure-cert-path="./ssl_dir/cert.pem"
|
||
|
|
```
