Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

swift-mq

swift-mq is a lightweight in-memory message queue system for Node.js. It provides basic queue functionalities including message prioritization, delayed processing, retries, and scheduling, designed to be simple and easy to integrate into your applications.

Features

Priority Queue: Supports priority levels for messages. Higher priority messages are processed before lower priority ones.

Delayed Messages: Allows scheduling messages to be processed after a specified delay. This is useful for deferred tasks or scheduling tasks at a future time.

Retries: Configurable number of retries for processing messages in case of failures. Useful for handling transient errors during processing.

Scheduled Jobs: Supports scheduling messages to be processed at specific times. This allows for advanced scheduling of tasks.

Batch Processing: Enqueue and process multiple messages in batches, improving efficiency when dealing with large volumes of messages.

Queue State Logging: Logs the state of the queue, including the number of messages and their details. This can be helpful for debugging and monitoring.

Installation

npm install swift-mq

Usage


const express = require('express');
const { SimpleInMemoryQueue } = require('swift-mq'); // Adjust path if necessary

const app = express();
const queue = new SimpleInMemoryQueue();

app.use(express.json());

// Enqueue a message
app.post('/enqueue', (req, res) => {
  const { task, payload, priority, delay, retries, scheduledAt } = req.body;
  queue.enqueue({ task, payload, priority, delay, retries, scheduledAt });
  res.status(200).send('Message enqueued');
});

// Dequeue and process a message
app.get('/process', (req, res) => {
  const message = queue.dequeue();
  if (message) {
    console.log('Processing message:', message);
    res.status(200).send('Message processed');
  } else {
    res.status(200).send('No messages in the queue');
  }
});

// Start the server
const PORT = 3000;
app.listen(PORT, () => {
  console.log(`Server is running on port ${PORT}`);
});
