WebTransport Browser Client

Browser clients connect to the MOQ relay via the WebTransport API. No plugin or additional software is required — any browser supporting WebTransport over HTTP/3 works.

Connection URL format:

https://<host>:<port>/moq

Default example: https://your-server.com:4433/moq

Self-Signed Certificate Pinning

When using a self-signed certificate (local development), the browser requires the certificate’s SHA-256 public key hash. The hash is printed to the server console at startup in multiple formats. To generate it manually:

openssl x509 -in server-cert.pem -pubkey -noout 
  | openssl pkey -pubin -outform der 
  | openssl dgst -sha256 -binary 
  | base64

Pass this value as serverCertificateHashes in your WebTransport constructor:

const transport = new WebTransport(url, {
  serverCertificateHashes: [{ algorithm: 'sha-256', value: certHashBytes }]
});

Test Page

The plugin ships with a test page at webapps/live/moq/webtransport_client.html. Open it in a browser, enter your server address and certificate hash, and verify connectivity.
