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 🙏

Latch Timer Node for Node-RED

Author: Harshad Joshi (GitHub: hj91)

Overview

The Latch Timer Node for Node-RED is a custom node that acts as a timer with a latch functionality. The node takes a boolean input (true or false) or a 'reset' command. Depending on the input, it initiates a timer or resets the timer to its default state.

Use Cases

This node is particularly useful in scenarios where you want to hold a certain state (true or false) for a predefined time duration, such as:

  • Turning on a device for a set amount of time.
  • Simulating pulses in time-based control systems.
  • Holding a state for a specified duration in state-machine implementations.

Functionality

The Latch Timer Node operates based on the input message payload:

  • If the payload is true, the node initiates a timer for the duration set by the user in the node configuration. The output of the node during this time is true. After the timer duration has elapsed, the output is reset to false.
  • If the payload is false, the output of the node is set to false. No timer is initiated in this case.
  • If the payload is 'reset', the timer (if running) is immediately reset, and the output is set to false.

The node displays the current status under the node in the flow editor:

  • "timer running" (green): The timer has been initiated and is currently running.
  • "timer reset" (red): The timer has been reset and is not running.
  • "timer completed" (blue): The timer has completed its run.

Installation

You can install this node directly from the Node-RED interface by searching for "latch-timer" in the palette, or manually using npm
