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 🙏

Readme

@windingtree/sdk-queue

This package provides a task queue system designed to manage jobs that need to be executed in an asynchronous, distributed manner.

Installation

pnpm i @windingtree/sdk-queue

Key concepts

This library introduces several classes:

  1. Job: This class represents a job, which is a unit of work that the queue needs to execute. A job has properties like id, handlerName, data, status, isRecurrent, recurrenceInterval, maxRecurrences, and retries.

  2. JobHandler: This is a function that a job runs when it's its turn to be executed by the queue.

  3. JobHandlerRegistry: This class manages job handlers. It allows for registering and retrieving handlers by name.

  4. Queue: This is the main class of this package. It's responsible for managing and executing jobs.

  5. JobStatus: An enum representing the different states a job can be in.

Usage

import { Queue, JobConfig } from '@windingtree/sdk-queue';

// Create a new queue
const queue = new Queue({ concurrencyLimit: 5 });

// Register a job handler
queue.registerHandler('myHandler', async (data) => {
  // Process data here
  console.log(data);
  return true;
});

// Create a job config
const jobConfig: JobConfig = {
  handlerName: 'myHandler',
  data: { key: 'value' },
  maxRetries: 3,
};

// Add a job to the queue
const jobId = queue.add(jobConfig);

// You can also get a job
const job = queue.get(jobId);

// Or cancel a job
queue.cancel(jobId);

// Or delete a job
queue.delete(jobId);
