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

@bufferstack.io/mqtt-socket.io-gateway

A Node.js gateway bridging MQTT brokers and web clients via Socket.IO for real-time, bidirectional IoT messaging.

Features

  • Bidirectional communication between MQTT and Socket.IO clients
  • Secure MQTT connections with TLS and authentication
  • Dynamic MQTT topic subscription management
  • Outbound message queueing during MQTT broker disconnects
  • Configurable logging and CORS support
  • Includes CLI clients and a web test client

Installation

Install the package dependencies:

npm install

Start the gateway server:

npm start

Or run directly via Node.js:

node index.js

Configuration

Edit the config.toml file to configure the gateway:``

[mqtt]
url = "mqtts://broker.example.com:8883"
topics = ["sensor/#"]

[socketio]
port = 3000

[queue]
enabled = true
maxSize = 1000

[log]
level = "info"

  • Set your MQTT broker URL and credentials
  • Define default MQTT topics to subscribe to
  • Configure Socket.IO server port and CORS options
  • Enable outbound message queue and set logging verbosity

Usage

  • Web client: Open client.html in a browser for interactive MQTT-Socket.IO testing
  • Publish CLI: Use mqtt-push-client.js to send MQTT messages via the gateway
  • Subscribe CLI: Use mqtt-pull-client.js to subscribe and receive MQTT messages

Example to publish a message from the CLI client:``

node mqtt-push-client.js
