nosync

Prevent *Sync functions from being run after the first tick

Usage no npm install needed!

<script type="module">
  import nosync from 'https://cdn.skypack.dev/nosync';
</script>

Want to prevent accidentally calling sync functions?

require("nosync") will clog that drain for you, by making all sync functions throw after the next tick.

This still allows you to do whatever you need to in the setup phase of your program, where synchronous IO is a good thing.
