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

rum [<static_dir>] <outfile> [-- <browserify>]
  Watchify plus static file server plus auto-reload.

Options:
  <static_dir>  Directory of static files to serve, images/fonts
                If omitted, the server is disabled

  <outfile>     Required. Where to dump the browserify bundle

  <browserify>  Arguments after the '--' will be passed along to browserify

  --exec, -x    Shell command to run on each update before browserify,
                and before reload. Will capture any preceeding
                --watch arguments, which are not already captured by
                another --exec. Can use this multiple times.

  --watch, -w   Additional glob pattern to monitor for changes.
                Can use this multiple times. Position is important.
                Will apply to the next --exec argument or to the
                browserify watcher if one is not found.

  --port, -p    Bind server to this [address:]port instead of 0.0.0.0 and
                and random port

  --router, -r  Redirect all requests to this path but keep the
                displayed url unchanged. Use this if you've got
                client-side routing and want to avoid 404s.

  --version, -v Show version number

Basic usage:
  rum dist dist/bundle.js -- src/index.js
Watch scss:
  rum -w 'src/**/*.scss' -x 'make dist/bundle.css' dist dist/bundle.js -- src/index.js
More browserify options:
  rum dist dist/bundle.js -- src/index.js -t babelify -t [envify purge]

You can also listen for reload events in your browser bundle and do something special that depends on the file name. For example, you can hot reload stylesheets like this:

// $ rum dist dist/index.js -w 'src/**/*.scss' -x 'make dist/bundle.css' -- src/hot-css.js src/app.js

// src/hot-css.js
require('rum').on('reload', function (files) {
  for (let index = 0; index < files.length; ++index) {
    if (!/\.(scss|sass|less|css)$/.test(files[index])) {
      return window.location.reload(true)
    }
  }

  // Only the css was changed. Time for hot reload!
  reloadCSS('index.css')
})

/**
 * Reload just the css bundle <link rel="stylesheet" href="...">
 * without refreshing the whole page
 */
function reloadCSS(href) {
  let links = document.getElementsByTagName('link')
  let index = links.length
  let cur = null
  while (cur = links[--index]) {
    if (cur.getAttribute('href') === href) {
      cur.href = ''
      cur.href = href
      console.warn('reloaded ' + href)
      return
    }
  }
}

Using VIM?

You may need to add set backupcopy=yes to your vimrc. The default method of saving files does not play nicely with filewatchers like chokidar.
