Tiny CFI

Generate a minimal CFI for a target node, with only the DOM as a dependency.

Caveats

A bunch. This is very rudimentary. Only the element steps are generated. No ranges, no text offsets, no ID assertions.

Usage

generateCfiSteps(target, root)

Example

Given the HTML:

<!DOCTYPE html>
<html>
  <head></head>
  <body>
    <div id="div-2">
      <p id="p-2">
        Hello world
      </p>
      <div></div>
      <div id="div-6"></div>
      <div></div>
    </div>
  </body>
</html>

Running npm i && npm test should print out /4/2/6

Refer to main.js as a code example.
