Easily build your customized Nostr Relay.
I think examples are the best way to explain how to use this library.
import { NostrRelay, createOutgoingNoticeMessage } from '@nostr-relay/core';
import { EventRepositorySqlite } from '@nostr-relay/event-repository-sqlite';
import { Validator } from '@nostr-relay/validator';
import { WebSocketServer } from 'ws';
async function bootstrap() {
const wss = new WebSocketServer({ port: 4869 });
// You can implement your own event repository. It just needs to implement a few methods.
const eventRepository = new EventRepositorySqlite();
const relay = new NostrRelay(eventRepository);
const validator = new Validator();
wss.on('connection', ws => {
// Handle a new client connection. This method should be called when a new client connects to the Nostr Relay server.
relay.handleConnection(ws);
ws.on('message', async data => {
try {
// Validate the incoming message.
const message = await validator.validateIncomingMessage(data);
// Handle the incoming message.
await relay.handleMessage(ws, message);
} catch (error) {
if (error instanceof Error) {
ws.send(JSON.stringify(createOutgoingNoticeMessage(error.message)));
}
}
});
// Handle a client disconnection. This method should be called when a client disconnects from the Nostr Relay server.
ws.on('close', () => relay.handleDisconnect(ws));
ws.on('error', error => {
ws.send(JSON.stringify(createOutgoingNoticeMessage(error.message)));
});
});
}
