@suaveplan/network-bootstrap - Network bootstrap plugin: pluggable discovery-strategy chain, persistent peer cache, retry-with-jitter and NetworkBus integration for finding initial peers in the @suaveplan/network mesh
Summary
Pluggable peer-discovery chain, persistent peer cache, and NetworkPlugin
wrapper for the @suaveplan/network mesh. Provides the canonical way for a
freshly started node to find its first peers.

Basic Example
import { NetworkNode } from "@suaveplan/network";
import {
BootstrapPlugin,
type DiscoveryStrategy,
} from "@suaveplan/network-bootstrap";
const seedStrategy: DiscoveryStrategy = {
name: "seed",
async discover() {
return [
{
peerId: "p1",
addresses: ["/ip4/127.0.0.1/tcp/9001"],
lastSeen: Date.now(),
source: "seed",
},
];
},
async isAvailable() {
return true;
},
};
const plugin = new BootstrapPlugin({
strategies: [seedStrategy],
discoveryTimeoutMs: 2000,
});
const node = new NetworkNode().use(plugin);
await node.start();
Advanced Example
import { NetworkNode } from "@suaveplan/network";
import { MemoryStorage } from "@suaveplan/storage";
import { BootstrapPlugin } from "@suaveplan/network-bootstrap";
const storage = new MemoryStorage();
const plugin = new BootstrapPlugin({
strategies: [mdnsStrategy, dhtStrategy, seedStrategy],
cache: {
maxPeers: 500,
ttlMs: 600_000,
persistKey: "net:peers",
storage,
},
discoveryTimeoutMs: 2500,
maxConcurrentDiscoveries: 3,
retry: {
maxAttempts: 4,
initialDelayMs: 200,
maxDelayMs: 5000,
factor: 2,
},
maxCollectedPeers: 20,
});
const node = new NetworkNode().use(plugin);
node.networkBus.on("bootstrap:exhausted", (ev) => {
console.log(`bootstrap done — ${ev.collected} peers found`);
});
await node.start();
