Automatic polyfill about es6-promise

[stefanpenner]

@jakearchibald this is your call, tell me what you want and I'll make it happen

[longlho]

+1 for this :)

[RReverser]

Totally +1

[DavidBruant]

I load polyfills as inline scripts. I would love to have a drop-in script as well.

[filaraujo]

+1 for automatic declaration

@stefanpenner is there a downside to this I'm not seeing?

[mariusGundersen]

Isn't this the way that most polyfills work?

[stefanpenner]

@jakearchibald no downside I am aware. Just provide a +1 or -1 and I'll doit.

The polyfill should take over if !(self.Promise && !Promise.cast), although we should provide a way to force-overwrite for cases like subclassing.

[stefanpenner]

sounds good, which evergreen browser has cast ?

[jakearchibald]

Just Safari (if you count that as evergreen). It's fixed in the nightlies though.

[stefanpenner]

fixed in #69

[yethee]

cast is part of the specification?
How to prevent overriding the native Promise for the latest version of Firefox and Google Chrome?

[indianburger]

So we use es6-promise in a javascript file that's a third part script on a page. Being a 3rd party script, we never modify the host page's native objects and this change makes it impossible for us to continue using es6-promise as is.

I wanted to check with you all before I create a fork. Do you have any suggestions for my use case? Would you be open to changing the polyfill behaviour somehow? I'm not super familiar with this code base, but I wonder if you can detect if the module is require'ed (browserify) then don't polyfill.

i don't mind shipping promise.polyfil.js (which would auto polyfil) and promise.js (which would be well behaved)

[indianburger]

That would be really really sweet

[stefanpenner]

That would be really really sweet

instead of forking, maybe you can contribute that ;)

[indianburger]

Happy to give it a shot this weekend. Any pointers as I go through the code?
