Will require fail if imported as an ES module in Node?

[mrjacobbloom]

Would we need to use createRequire? Can we circumvent this since new Node should be able to use Symbol.for(...)?

Should look something like

const isNode = typeof process !== undefined;
let symbolInspect;
if(isNode) {
  if (typeof require === 'undefined') {
    symbolInspect = Symbol.for('nodejs.util.inspect.custom');
  } else {
    try {
      symbolInspect = require('util').inspect.custom;
    } catch {}
  }
}

The shared symbol was introduced in Node 10.12. 10 is in LTS and hits maintenance LTS on April 1. I think we can safely drop the require('util') in favor of

const symbolInspect = isNode ? Symbol.for('nodejs.util.inspect.custom') : null;
