Allow for no json file (and only inline values from gulp)

[bdwain]

the use case i'm thinking of is pass a command line param to gulp and pass that directly to the plugin

gulpNgConfig('myApp.config', {
  constants: {
    apiUrl: argv.apiUrl
  }
});

this would be especially nice since it allows you to avoid putting the value of your constants in source control, which is what drew me to this in the first place.

my workaround for the time being will be to create a json file that is just {}

Hi @ajwhite and @bdwain,

I'm thinking of contributing to this issue. Have one of you already started to think about it ?

Nope, feel free

[bdwain]

i haven't either.

You can achieve this using buffer-to-vinyl.

var b2v = require('buffer-to-vinyl');
var gulpNgConfig = require('gulp-ng-config');

gulp.task('make-config', function() {
  var json = JSON.stringify({
    // your config here
  });

  return b2v.stream(new Buffer(json), 'config.js')
    .pipe(gulpNgConfig('app.config'))
    .pipe(gulp.dest('build'));
});

Is this worth putting in the readme? I can whip up a PR.

@psalaets great call, one of the beautiful things about streams is that we can & should be extremely modular and allow for single responsibility -- piping the result of that into gulpNgConfig would be ideal here. We can add an "Additional Usages" section that shows how this can be integrated with other preceding or proceeding streams. I think this is a great entry to start off a new "Additional Usages" section. Feel free to PR!
