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 🙏

Nexmosphere extension for signageOS Front Applet

This library provides a seamless integration of npm modules @signageos/nexmosphere-sdk and @signageos/front-applet.

@signageos/front-applet library provides a set of interfaces for sensors and actuators and this library wraps around @signageos/nexmosphere-sdk library and exposes it as implementation of those interfaces.

That way, when you write an applet with @signageos/front-applet, you can use the sensors and actuators and if you later decide to change the underlying hardware of those sensors/actuators, you only need to replace the factories of the sensors/actuators objects.

It's also useful if you want to implement multiple diferrent sensors/actuators from different providers but want to use them all the same way in your code.

Basics

Every application starts with creating a nexmosphere instance that needs a serial port.

const sos = require('@signageos/front-applet');
const Nexmosphere = require('@signageos/front-applet-extension-nexmosphere');

sos.onReady().then(async () => {
    const serialPort = await sos.hardware.openSerialPort({
        device: '/dev/ttyUSB0',
        baudRate: 115200,
    });
    const nexmosphere = new Nexmosphere(serialPort);
});

Example usage

This library is just a wrapper for @signageos/nexmosphere-sdk. You can find more detail about the various APIs there.

Button

const buttonAddress = 2;
const buttonIndex = 0;
const button = nexmosphere.createButton(buttonAddress, buttonIndex);

button.on('pressed', () => console.log('buton was pressed'));
button.on('released', () => console.log('buton was released'));

RFID Antenna

const rfidAntennaAddress = 5;
const rfidAntenna = nexmosphere.createRfidAntenna(rfidAntennaAddress);

rfidAntenna.on('picked', (tag) => console.log(`tag ${tag} was picked`));
rfidAntenna.on('placed', (tag) => console.log(`tag ${tag} was placed`));
