A headless peer for the dot demo: it speaks the same wire format (ALPN iroh-helloiroh-dot/0, 8-byte f32 x, f32 y frames) but just prints every received position to the console instead of rendering a dot.

Uses the iroh JavaScript bindings (@number0/iroh). Requires Node 20.3+.

npm install

Listen and print your endpoint id (paste it into the Connect field on a phone/desktop peer):

node read-dots.js

Or dial out to a peer's endpoint id:

node read-dots.js <endpoint-id>

Either way, incoming frames print as:

[8afb782ee0] x=+0.412 y=-0.083

When dialing, the reader sends a single (0, 0) frame so the QUIC stream becomes visible to the peer — your "dot" sits at the origin on their screen.
