@danu/danu

Browser library for Fledger network, compiled to WebAssembly.

Installation

For local development:

npm install file:../package/pkg

When published:

npm install @danu/danu

Usage

import init, { FlNode, initialize } from '@danu/danu';

// Initialize WASM module
await init();

// Set up logging and panic hooks
initialize();

// Create a node instance
const node = new FlNode();

// Connect to signal server
await node.connect('wss://signal.fledg.re');

// Get connection status
const status = node.get_connection_status();
console.log(status);

// Get statistics
const stats = node.get_stats();
console.log(stats);

// Set up event listener for asynchronous events
node.set_event_listener((event) => {
  console.log('Event:', event.type, event.data);

  switch (event.type) {
    case 'connecting':
      console.log('Connecting to:', event.data.signal_server);
      break;
    case 'connected':
      console.log('Connected!');
      break;
    case 'message':
      console.log('Message received:', event.data);
      break;
    // ... handle other events
  }
});

// Remove event listener when done
node.remove_event_listener();

Event System

The package emits events for asynchronous operations. Set up a listener to receive them:

node.set_event_listener((event: { type: string, data: any }) => {
  // Handle events
});

Common Event Types:

• connecting - Connection attempt started
• connected - Successfully connected
• disconnected - Connection closed
• message - Message received from peer
• peer_joined - Peer joined the network
• peer_left - Peer left the network
• error - An error occurred
