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-topic-timeframe-trigger

Node-RED node which observes input topics and only produces an output if n distinct topics are received n times each within the specified time frame.

Installation

Change directory to your node red installation:

$ npm install node-red-contrib-topic-timeframe-trigger

Outputs

When enough messages are received to trigger, a message is output as per the configuration. In addition, all of the messages received within the timeframe are added to the message as an array property called triggers.

Enabling extra debugging

Install node-red-contrib-config and drag a config node into your workspace. Configure the node to set a global variable called topic-timeframe-trigger with a JSON value of {"debug": true}. Also make sure that the config tickbox for active is unchecked. Redeploy. Now click the button on the config node. This will trigger all instances of topic-timeframe-trigger to write extra logging to the os syslog next time they're invoked.
