HRPC Demo — Unary RPC (ping/pong) over a connection

What this example does

HRPC on a connection: HRPC is auto-enabled when a peer connects. Either tab can use "Ping peer" to get a pong (unary RPC). No manual attach step in the UI after connect.

Prerequisites

Install the BridgeSwarm extension and native host before opening this example.

How to run

npm run examples

Open http://127.0.0.1:4173/hrpc-demo/ (two tabs for P2P). Do not use file://.

Usage

Click Join topic (default bridge-swarm-hrpc-demo).
Open the same page in another tab and join the same topic.
When connected, HRPC is enabled automatically; use Ping peer (optionally enter a value). Use Retry HRPC on selected connection if the first enable is still pending.
Click Leave and destroy when done.

APIs and concepts

Swarm/connection as in chat: BridgeSwarm.ready(), new BridgeSwarm(), swarm.join(), swarm.on('connection'), conn.connId, conn.on('end'), conn.on('error').
BridgeSwarm.request('attachHrpc', { connId }) — Enable HRPC on the connection (called automatically on each new connection).
BridgeSwarm.request('hrpcInvoke', { connId, method: 'ping', args }) — Invoke the unary ping RPC; host runs HRPC on the connection, browser only invokes ping.
