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

node-red-contrib-stepper

This Node-RED node facilitates the generation of stepped numerical sequences with user-defined parameters. It is ideal for scenarios where a controlled sequence of numbers is required, such as in simulations, iterative testing, or gradual value changes in automation tasks.

Installation

Install the node directly by using the Node-RED Palette Manager or by running the following command in your Node-RED installation directory:

npm install node-red-contrib-stepper

Features

  • Configurable Range: Set start and end points for the sequence.
  • Step Control: Define the increment or decrement step size.
  • Timing Adjustment: Specify the duration for each step.
  • Dynamic Control: Start, stop, resume, and reset the sequence dynamically with input messages.

Usage

Configure the node with the following settings:

  • From: The initial value of the sequence.
  • To: The final value of the sequence.
  • Step: The value by which to increment or decrement.
  • Duration: The delay between steps in milliseconds.

Control the node by sending a message with a boolean true payload and one of the following topics:

  • start: Initiates the sequence.
  • stop: Halts the sequence.
  • reset: Resets the sequence to the initial From value.
  • resume: Resumes the sequence from where it was stopped.

Example

Refer the example included with this node

Copy and import it into your Node-RED environment to see the stepper node in action.
