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

IMU BLE / MQTT Subscription

This package allows code in a web page to subscribe to data that is published by an ESP32 connected to a BNO055 IMU. The ESP32 should be running either the MicroPython code in imu-tools, or the Arduino (C++) code in Arduino-BLE-IMU. See those projects for information on how to configure the ESP32.

Additional examples are in osteele/imu-client-examples.

Usage – MQTT

To use this code with an MQTT broker, include the MQTT library in the header (between the <head> and the </head> tags) of the HTML file:

<script src="https://cdn.jsdelivr.net/npm/[email protected]/paho-mqtt.js"></script>

Add the following to sketch.js to import the onSensorData function, and use it to subscribe to sensor data:

import {
  mqttConnect,
  onSensorData,
} from "https://cdn.jsdelivr.net/npm/imu-tools/index.js";

mqttConnect({ hostname: "example.com" });
onSensorData((data) => console.info("sensor data:", data));

The hostname option to mqttConnect can also specify a port number: "example.com:1877". The options may also include username, password, and deviceid. If deviceId is specified, only messages from the specified device are processed.

Connection Settings Control Panel

The MQTT broker can be set by enabling a control panel that allows the user to specify the MQTT connection settings.

Add the following to the HTML header:

<script src="https://cdn.jsdelivr.net/npm/[email protected]/build/dat.gui.min.js"></script>

The page will now display a control panel in the upper right corner.

The location of the control panel can be customized by adding an HTMl element with id connection-gui.

The controller saves the connection settings to local storage. They are used by all pages that include this library.

Acknowledgements

This code uses the Eclipse Paho JavaScript Client for MQTT connectivity. It uses dat.gui to display the control panel.
