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

ftp-watcher

Watch an FTP server for file and directory tree changes.

NPM

Install

npm install --save ftp-watcher

Run tests

npm run test

Usage

Create a new FtpWatcher instance and pass an options object with properties ftpCredentials and cron. Since ftp-watcher depends on the popular FTP client module ftp, the ftpCredentials must match the options object that can be passed to ftp's ftp.connect() method.

Calling watch() on the new ftp-watcher instance causes it to emit 'snapshot' events with a frequency set by the passed cron expression. Each 'snapshot' event contains an array of path strings representing a complete snapshot of the FTP server's directory tree. A fileExtension and/or fileNameContains string can be passed optionally to filter the emitted snapshots. An ftp-watcher instance can be stopped by calling its stop() method.

const FtpWatcher = require('../src/index')

const ftpCredentials = {
  host: 'speedtest.tele2.net' // a public FTP test server
  // port: defaults to 21
  // user: defaults to anonymous
  // password: anonymous@
}

const speedtestWatcher = new FtpWatcher({
  ftpCredentials: ftpCredentials,
  cron: '*/10 * * * * *'
  // fileExtension: '.zip', // optional
  // fileNameContains: 'GB' // optional
})

speedtestWatcher.on('error', handleError)
speedtestWatcher.on('snapshot', handleSnapshot)

function handleSnapshot (snapshot) {
  console.log(snapshot)
  // speedtestWatcher.stop()
}

function handleError (error) {
  console.error(error)
}

speedtestWatcher.watch()
