Cannot resolve dependency 'async_hooks'

See original GitHub issue

🐛 bug report

Parcel doesn’t seem to know that async_hooks is a Node.js builtin when bundling with --target node.

parcel build src/index.js --target node --bundle-node-modules

🤔 Expected Behavior

A require('async_hooks') should be left as-is.

😯 Current Behavior

An error is thrown.

🚨  /app/node_modules/cls-hooked/context.js:7:28: Cannot resolve dependency 'async_hooks'
   5 | const assert = require('assert');
   6 | const wrapEmitter = require('emitter-listener');
>  7 | const async_hooks = require('async_hooks');

   9 | const CONTEXTS_SYMBOL = 'cls@contexts';
  10 | const ERROR_SYMBOL = 'error@context';

💁 Possible Solution

Add it to node-libs-browser?

require('async_hooks');

Is there any possible workaround for the 1.x branch - I’m stuck with parcel 1.x, because it is a dependency of @aws-cdk/aws-lambda-nodejs ?

This is only fixed in Parcel 2, not in Parcel 1.x.
