[Question] Non-ESM Support

[gaby]

Is there a way to use this library without ESM, which has been abandoned for a long time?

[tcollinsworth]

Aside from native ESM by using package.json type: module or loading from a .mjs instead of .js file, not sure. I recently leaned it's possible to start node with -r esm or -r esm-wallaby too. Then the project does not need to directly depend on esm. The esm library is still widely used. The esm-wallaby library is a fork of esm but adds optional-chaining (elvis), so that's mostly what I'm using these days. I haven't switched to native esm because of the limitations on code modification which is needed for sinon stubs/spies and newrelic agent to instrument code. Been trying to identify solutions to those issues, but currently unaware of alternatives that won't require major refactoring.

@tcollinsworth Thank you for your time and great explanation, looking forward to using this library to resolve dns issues!

Can't get this to work w/ jest due to the module exporting ESM

ugh
I need this too

You can dynamically load ESM module before loading this module. Alternatively, if you are using native esm, I could create a native esm version.
