Broken dependency viz.js – "Invalid asm.js: Function definition doesn't match use"

Expected Behavior

I am trying to convert a simple smcat file to SVG:

➜ cat test.smcat
initial,
"media player off",

"media player on" {
  stopped, playing, paused;

  stopped => playing : play;
  playing => stopped : stop;
  playing => paused  : pause;
  paused  => playing : play;
  paused  => stopped : stop;
};

initial            => "media player off";
"media player off" => stopped           : power;
"media player on"  => "media player off" : power;

I expect smcat -o test.svg < test.smcat to create that SVG file.

Current Behavior

➜ smcat -o test.svg < test.smcat
(node:11096) V8: /usr/local/lib/node_modules/state-machine-cat/node_modules/viz.js/viz.js:33 Invalid asm.js: Function definition doesn't match use

Possible Solution

Seems this is related to this upstream bug in viz.js that was never fixed. Now this project is archived, and it seems there is no obvious solution to the issue. I think it cannot be used as a dependency anymore.

The same error is referenced in this issue as well. One solution is proposed: to use dagre instead.

Your Environment

• Version used: 5.3.3
• Node version: 12.10.0
• Operating System and version: macOS 10.14.6

you can instead use the native graphviz like so …

smcat -T dot -o - | dot -T svg > test.svg

(believe me when I say dagre is not an alternative … 😃 )
