@postgresx/bun-listen

Bun-native PostgreSQL LISTEN/NOTIFY client used by @postgrex/noredis. It is published as a separate package so Bun projects can use it directly without installing the full @postgrex/noredis toolkit.

It connects through Bun.connect() and implements the PostgreSQL wire protocol for notification workloads. It supports TLS negotiation, MD5, cleartext, and SCRAM-SHA-256 authentication.

Install

bun add @postgresx/bun-listen

Usage

import { createPgListener } from "@postgresx/bun-listen";

const listener = createPgListener(process.env.DATABASE_URL!, {
  channels: ["events"],
  onNotify(channel, payload) {
    console.log(channel, payload);
  }
});

await listener.notify("events", JSON.stringify({ type: "ready" }));

listener.close();
