url: extend url.format to support WHATWG URL by jasnell · Pull Request #10857 · nodejs/node · GitHub

Removes the non-standard options on WHATWG URL toString
and extends the existing url.format() API to support
customizable serialization of the WHATWG URL object.

This does not yet include the documentation updates
because the documentation for the new WHATWG URL object
has not yet landed.

Example:

const url = require('url');
const URL = url.URL;
const myURL = new URL('http://example.org/?a=b#c');
const str = url.format(myURL, {fragment: false, search: false});
console.log(str);
  // Prints: http://example.org/

url, whatwg-url

/cc @watilde @nodejs/url

Symbols added this way are enumerable(can be verified via Object.getOwnPropertyDescriptor(url, kFormat)), I believe test-whatwg-url-properties doesn't catch this because for-in only iterates over string keys, but since Reflect.enumerate is withdrawn in ES2016 I can't think of a way to make that test more complete...anyways I think we should useObject.defineProperty here to make it non-enumerable, or just move this function out and use .call to call it properly?

Using defineProperty is fine.

Putting the symbols here at all (enumerable or not) creates an observable difference from the spec via Object.getOwnPropertySymbols. But I guess there are several of those already (special/cannotBeABase) so IMO it's probably not worth changing...

How much of a performance impact does this have on non-whatwg url usage?

It may be another topic, but from the viewpoint of making the URL object behave the same as the standard, is URL.inspect() OK even when it can be called? I think it could be replaced with util.inspect when it needs.

Here is an example:

node/test/parallel/test-whatwg-url-parsing.js

Lines 147 to 149 in d86ff5f

    
           const res = url.inspect(null, { 
        
             showHidden: showHidden 
        
           });

@mscdex ... the performance hit incurred by the addition of the new instanceof URL check is, unfortunately, non-trivial. I'll play around with it to see how I can reduce the cost.

@watilde ... we now have the option of using a symbol for the inspect function. It would make sense to switch to using that instead of the inspect() function itself.

@mscdex @joyeecheung ... updated. modified the changes in url.format a bit to reduce the cost of the additional check.

Is the unicode option name from the spec, from compatibility with the old url, or is it up for debate? I don’t think it’s conveying the semantics very well (like, I have to look at the tests in this PR to see which behaviour maps to which value). How does something like decodeIDNA: true/false sound to you?

(Strange, my response ended up both in my own review and here, but when I deleted that one in my review this one disappeared too)..

I think options is neither in the spec nor in the old url.format. For me the meaning of unicode is pretty straightforword(maybe it's just me though). The two serialization alternatives are named Domain to ASCII and Domain to Unicode in the spec.

The unicode flag is consistent with the URL standard, yes (see: https://url.spec.whatwg.org/#host-parsing). To be fair, however, that is on parse side and this is on the serialization, but there is precedent at least.

Eh, if it’s in the standard, even just on the parse side, it’s probably best to leave it like that. Thanks for pointing it out.

For me the meaning of unicode is pretty straightforword(maybe it's just me though).

Well, if it’s working and people know what the option describes, that’s probably just fine then. (At least in my head, unicode: true sounds like it could both mean enabling a) decoding of the hostname from punycode to Unicode or b) encoding of the hostname from Unicode to punycode)

I will make sure that the relevant documentation appropriately covers the option and makes its function clear

Why use Boolean() instead of !! here?

Personal preference with regards to code clarity

nit: extra whitespace here

This still hasn't been fixed.

I think keep it as this.toString() is closer to how the spec defines href as the stringifier.

The result is the same. Using this[kFormat]({}) here avoids an unnecessary property access.

These two lines are not needed as they are the default. However, the trend in Web APIs seems to be make symbol properties configurable and writable, so I'd recommend sticking to that

Yes, I know they are the default. I prefer to be explicit. Also, because this is an internal only method, I prefer to keep these values

LGTM except it needs rebase.

@mscdex ... any further thoughts on this?

@jasnell Performance-wise the lib/url.js changes LGTM.
