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 🙏

Examples

loop mode

const NfcpyId = require('node-nfcpy-id').default;
const nfc = new NfcpyId().start();

nfc.on('touchstart', (card) => {
  console.log('Card ID: ' + card.id);

  // card.type is the same value as that of nfcpy.
  // 2: Mifare
  // 3: FeliCa
  // 4: Mifare (DESFire)
  console.log('Card Type: ' + card.type);
});

// If the `mode` is `loop` or `non-loop`, event will occur when the card is removed
nfc.on('touchend', () => {
  console.log('Card was away.');
});

nfc.on('error', (err) => {
  // standard error output (color is red)
  console.error('\u001b[31m', err, '\u001b[0m');
});

non-loop mode

const NfcpyId = require('node-nfcpy-id').default;
const nfc = new NfcpyId({mode: 'non-loop'}).start();

nfc.on('touchstart', (card) => {
  console.log('Card ID: ' + card.id);
  console.log('Card Type: ' + card.type);
});

// If the `mode` is `loop` or `non-loop`, event will occur when the card is released
nfc.on('touchend', () => {
  console.log('Card was away.');

  // Card reading will start five seconds after the card is released
  setTimeout(() => {
    nfc.start();
  }, 5000);
});

nfc.on('error', (err) => {
  // standard error output (color is red)
  console.error('\u001b[31m', err, '\u001b[0m');
});

non-touchend mode

const NfcpyId = require('node-nfcpy-id').default;
const nfc = new NfcpyId({mode: 'non-touchend'}).start();

nfc.on('touchstart', (card) => {
  console.log('Card ID: ' + card.id);
  console.log('Card Type: ' + card.type);
});

nfc.on('error', (err) => {
  // standard error output (color is red)
  console.error('\u001b[31m', err, '\u001b[0m');
});

To start (restart) reading cards, use nfc.start().

To pause reading cards, use nfc.pause().

To stop this script, press control+C. By this, Python process will be killed at the same time.

To use this script with other than SONY Pasori RC-S380, it may be necessary to modify reader.py and add options to the parameter of constructor.

const NfcpyId = require('node-nfcpy-id').default;

// Put the modified Python script in the same directory.
const nfc = new NfcpyId({scriptPath: __dirname, scriptFile: 'new-reader.py'}).start();

// If the file name of the modified Python script is `reader.py`, `scriptFile` can be omitted.
// const nfc = new NfcpyId({scriptPath: __dirname}).start();
