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 🙏

Service for Zen Engine rules

Readme

Overview

This project provides an API service built with Express and TypeScript to handle business rules using the ZenEngine provided by GoRules. It simplifies the management and evaluation of business rules by providing endpoints for evaluation, retrieval, and storage.

Key Features

  • Evaluate business rules using the GoRules ZenEngine.
  • Save and retrieve JSON decision models (JDM).
  • Modular validation and error handling.

JSON Rule Structure

A valid rule for ZenEngine requires the following structure:

{
  "contentType": "decision",
  "nodes": [
    { "id": "1", "type": "start" },
    { "id": "2", "type": "decision", "conditions": { "key": "value" } }
  ],
  "edges": [
    { "from": "1", "to": "2" }
  ],
  "settings": {
    "type": "default",
    "description": "Sample Rule"
  }
}

Scripts

npm run dev: Starts the development server using nodemon.
npm run build: Compiles the TypeScript source to JavaScript.
npm start: Runs the production server.
npm run prod: Runs the service directly with ts-node.

Deployment

To deploy this service:

Build the project using npm run build.
Use a process manager like PM2 or a systemd service to start dist/index.js.
