Working with NPM modules shortcuts: center-code (s), npm-quick-run (nr) and Man for NPM (manpm)

I am showing several of my CLI tools that speed up working with NPM modules.

show centered, syntax highlighted JS or JSON files using center-code
run any npm script very quickly using the first matching prefix npm-run-quick. I am using nr bin name and show first ambiguous case (two script names match “s” prefix)
fetching any package README, searching for a section with the given text and showing it in the terminal using Markdown highlighting using manpm that is my Man for NPM

All tools are available now, any suggestions are welcome.

You can replay the downloaded recording in your terminal using the asciinema play command:

Use with stand-alone player on your website

Download asciinema player from the releases page (you only need .js and .css file), then use it like this:

<!DOCTYPE html>
<html>
<head>
  <link rel="stylesheet" type="text/css" href="asciinema-player.css" />
</head>
<body>
  <div id="player"></div>
  <script src="asciinema-player.min.js"></script>
  <script>
    AsciinemaPlayer.create(
      '/assets/31015.json',
      document.getElementById('player'),
      { cols: 80, rows: 35 }
    );
  </script>
</body>
</html>

See asciinema player quick-start guide for full usage instructions.

While this site doesn't provide GIF conversion at the moment, you can still do it yourself with the help of asciinema GIF generator utility - agg.

Once you have it installed, generate a GIF with the following command:

agg https://asciinema.org/a/31015 demo.gif

Or, if you already downloaded the recording file:

agg demo.cast demo.gif

Check agg --help for all available options. You can change font family and size, select color theme, adjust speed and more.

See agg manual for full usage instructions.
