Can't get promisify working with a basic example

See original GitHub issue

I’m really hoping that I’ve just continually missed something obvious here, but after trying for hours to use promisify, I’ve distilled things down to a VERY simple example that only logs “running” and never “then”. What have I missed or is this a bug?

<html>
    <head>
        <script src="http://requirejs.org/docs/release/2.1.2/minified/require.js"></script>
    </head>

    <body>

        <script>

            require(['https://cdnjs.cloudflare.com/ajax/libs/bluebird/2.10.1/bluebird.js'], function( Promise ) {

                var initServer = Promise.promisify( function( foobar ) {
                    console.log( 'running' );
                    return  true;
                } )( { foobar: 1 } ).then( function( ) {
                    console.log( 'then' );
                });

            });

        </script>

    </body>
</html>

haha. That fs example is why I’ve not understood sooner. Not ONE example out there is standalone (and thus clear). Thank you though, I did figure it out and am leaving it here for anyone else that might find it useful:

Here is a Gist that covers both approaches with errors: https://gist.github.com/rainabba/b83eed7f6317e5e7d945

for illustration purposes, don’t actually do this, use .promisifyAll() instead

const fs = require("fs");
const stat = Bluebird.promisify(fs.stat);

stat(__filename).then(console.log);
