Postgres Message Queue (PGMQ) JavaScript Client Library
As always:
First, Start a Postgres instance with the PGMQ extension installed:
docker run -d --name postgres -e POSTGRES_PASSWORD=password -p 5432:5432 quay.io/tembo/pgmq-pg:v1.2.1
Then:
import { Pgmq } from 'pgmq-js';
console.log('Connecting to Postgres...');
const pgmq = await Pgmq.new(
{
host: 'localhost',
database: 'postgres',
password: 'password',
port: 5432,
user: 'postgres',
ssl: false,
},
// { skipExtensionCreation: true }, Set this if you want to bypass extension creation (e.g. dbdev users).
).catch((err) => {
console.error('Failed to connect to Postgres', err);
});
const qName = 'my_queue';
console.log(`Creating queue ${qName}...`);
await pgmq.queue.create(qName).catch((err) => {
console.error('Failed to create queue', err);
});
interface Msg {
id: number;
name: string;
}
const msg: Msg = { id: 1, name: 'testMsg' };
console.log('Sending message...');
const msgId = await pgmq.msg.send(qName, msg).catch((err) => {
console.error('Failed to send message', err);
});
const vt = 30;
const receivedMsg = await pgmq.msg.read<Msg>(qName, vt).catch((err) => {
console.error('No messages in the queue', err);
});
console.log('Received message...');
console.dir(receivedMsg.message, { depth: null });
console.log('Archiving message...');
await pgmq.msg.archive(qName, msgId).catch((err) => {
console.error('Failed to archive message', err);
}); Supported Functionalities
