Use the latest punycode, since punycode(1.3.2) export with:
define('punycode', function() { return punycode; });
which isn't portable when using requireJS.

Node.js uses punycode 2.0.0 and it'd be best if we're in sync with them.

However punycode 2+ use ES6 features which are only supported in recent browsers, ideally browserify's node core shims work way back in old browsers too…

punycode 2.0.0 is actually identical to 1.3.2 except for the ES6 syntax. The best thing to do here might be to have a new punycode-browserify package that is punycode 2.0.0 compiled to ES5.

I don't think so.
// punycode, 1.3.2

define('punycode', function() {
    return punycode;
});

// punycode, 2.0.0

/** Define the public API */
const punycode = {

	 * @type String

	/**

	},
	'decode': decode,

};

module.exports = punycode;

Yes, browserify is mainly target convert ES6 to ES5, if browserify itself contain ES6 code.
Than its verfy difficult run in old browser.

Since you can't change it here. Let me try talk to punycode(1.3.2) to remove the uncomfortable amd id('punycode').

Could you help to do it?

Yes I think I worked on one a few months ago. I'll see if I can dig it up on the weekend.

I'm confused what the problem is with the AMD detection; couldn't that be trivially wrapped for CJS?
