Bluebird fails to load in a nwjs (nodewebkit) app

[NervosaX]

It gives me the error:

[23637:0312/105955:INFO:CONSOLE(81)] "Uncaught TypeError: Cannot read property 'isStatic' of undefined", source: file://.../dist/jspm_packages/npm/bluebird@2.9.10/js/browser/bluebird.js (81)

I've shortened the filenames for readability.

I can confirm that it worked fine in bluebird version 2.9.3, but I'd say that after commit 98b0252 the issue occurred.

Reading over the code in that commit, it seems to be because
typeof window === "undefined"
isn't part of the isNode check. If I add this line manually then my application runs.

Try with at least 2.9.6+

[NervosaX]

2.9.6 works. 2.9.13 fails.
I tried every version between 2.9.7 and 2.9.13 and each failed.

Does node webkit delete the global setImmediate function or something? That's what's being undefined ... that or process nextTick?

What does process.versions.node say in nw?

[NervosaX]

It gives me: "1.2.0"

[petkaantonov]

That means global.setImmediate is undefined, why does nw delete it?

[NervosaX]

I found this old commit for nw.js nwjs/nw.js#897

Sure enough if I add this line, bluebird will work.

if (typeof global !== "undefined") {
    window.setImmediate = global.setImmediate;
}

That's pretty unfortunate, as I'm not sure if it should be bluebird's problem to deal with that sort of issue.

[petkaantonov]

Well promises should always use nextTick anyway, I am not sure what the reason for the check even was originally. setImmediate is macro task.
