TIL that commonjs has a require cache. Basically, if you require a module once in the file, it gets cached and if you attempt to require the module a second time, EVEN IF THE CONTENT HAS CHANGED, you’ll get the cached version.

Usually this isn’t a problem but it bit me in the butt when I moved my remix app over to be using express. I had to call this function inside of my server code when remix finished rebundling.

function clearRequireCache() {
  Object.keys(require.cache).forEach(function (key) {
    delete require.cache[key]
  })
}

TIL during a basic async node training video, that the node core api exposes promisified (I think that’s a word) functions. For example fs provides a promise based API.
