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.

Workflow ES

Workflow ES is a workflow / saga library for Node.js (or modern browsers). It supports pluggable persistence and concurrency providers to allow for multi-node clusters.

Installing

Install the core npm package "workflow-es"

npm install workflow-es --save

Guides

Persistence

Since workflows are typically long running processes, they will need to be persisted to storage between steps. There are several persistence providers available as seperate npm packages.

Memory Persistence Provider (Default provider, for demo and testing purposes)
MongoDB
(more to come soon...)

Multi-node clusters

By default, the WorkflowHost service will run as a single node using the built-in queue and locking providers for a single node configuration. Should you wish to run a multi-node cluster, you will need to configure an external queueing mechanism and a distributed lock manager to co-ordinate the cluster. These are the providers that are currently available.

Queue Providers

SingleNodeQueueProvider (Default built-in provider)
Azure
Redis

Distributed lock managers

SingleNodeLockProvider (Default built-in provider)
Azure
Redis Redlock
