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 🙏

Shenzen Wearable Technologies X9 Cordova Plugin

This plugin uses the Bluetooth Low Energy (BLE) Central Plugin to connect to the SWT X9 wristband and return heart rate data and sleep data, and katzer's Cordova Background Mode Plugin to do it in the background.

Methods

startScan

Starts a scan for X9 devices and returns the MAC address of the first X9 found.

Example

  X9.scan()
    .then((x9) => {
      console.log('X9 found! MAC address', x9);
    }),
    .catch((errorMessage) => {
      console.log(errorMessage);
    });

readHeartRateData

Return heart rate data from an X9 device. If no device MAC address is input and no X9 is connected, this method will scan for and (if found) connect to an X9, start the heart rate monitoring service, and return the response. It will take ~20 or more seconds to run the heart rate monitoring service and return the results.

Example

  X9.getHeartRateData() // can also supply specific MAC address as in: X9.getHeartRateData('00:11:22:33:FF:EE')
    .then((responseUintArray, responseStr) => {
      console.log(responseUintArray);
      console.log(responseStr);
    }),
    .catch((errorMessage) => {
      console.log(errorMessage);
    });

Return Data

The ble plugin uses typed Arrays or ArrayBuffers for sending and receiving data. The success callback will return the data in the following format:

  var responseUintArray = new Uint8Array(response);
  var responseStr = String.fromCharCode.apply(String, new Uint8Array(response));
  success(responseUintArray, responseStr);

readSleepData

Return sleep data from an X9 device. If no device MAC address is input and no X9 is connected, this method will scan for and (if found) connect to an X9 and return the response from the sleep data service.

Example

  X9.getSleepData() // can also supply specific MAC address as in: X9.getSleepData('00:11:22:33:FF:EE')
    .then((responseUintArray, responseStr) => {
      console.log(responseUintArray);
      console.log(responseStr);
    }),
    .catch((errorMessage) => {
      console.log(errorMessage);
    });

Return Data

The ble plugin uses typed Arrays or ArrayBuffers for sending and receiving data. The success callback will return the data in the following format:

  var responseUintArray = new Uint8Array(response);
  var responseStr = String.fromCharCode.apply(String, new Uint8Array(response));

isConnected

Checks if connected to an X9.

Example

  X9.isConnected() // Checks if connected to any previously-scanned X9
    .then((x9) => {
      console.log('Connected to X9! MAC address', x9);
    }),
    .catch((errorMessage) => {
      console.log(errorMessage);
    });

  X9.isConnected('35:6B:D8:F5:5E:DA') // Check if connected to a specific X9
    .then((x9) => {
      console.log('Connected to X9! MAC address', x9);
    }),
    .catch((errorMessage) => {
      console.log(errorMessage);
    });
  
  X9.isConnected(['35:6B:D8:F5:5E:DA']) // Check if connected to a specific X9 in addition to any previously-scanned X9
    .then((x9) => {
      console.log('Connected to X9! MAC address', x9);
    }),
    .catch((errorMessage) => {
      console.log(errorMessage);
    });

disconnect

Disconnect from

Example

  X9.disconnect() // Disconnect from all devices
    .then((x9) => {
      console.log('Disconnected from X9. MAC address', x9);
    }),
    .catch((errorMessage) => {
      console.log(errorMessage);
    });

  X9.disconnect('35:6B:D8:F5:5E:DA') // Disconnect from specific X9
    .then((x9) => {
      console.log('Disconnected from X9. MAC address', x9);
    }),
    .catch((errorMessage) => {
      console.log(errorMessage);
    });

getVerbosity

Return the plugin's debug (logging) mode: false (default) is for silent operation (no console logs,) true is for verbose logging.

Example

  X9.getVerbosity();

toggleVerbosity

Toggle the plugin's debug (logging) mode: by default; no console logs are emitted; call toggleVerbosity to toggle verbose logging.

Example

  X9.toggleVerbosity();
