El plugin gulp-gh-pages

El plugin gulp-gh-pages simplifica el proceso de despliegue en gh-pages. Para ello ponemos una tarea:

    var gulp = require('gulp');
    var ghPages = require('gulp-gh-pages');

    gulp.task('deploy', function() {
      return gulp.src('./minified/**/*')
        .pipe(ghPages());
    });

/minified is the directory we're deploying, and /**/* means it will deploy all the files and directories recursively.

Now, you should be able to call your task by doing:

  gulp deploy

All files and directories inside of /minified will be pushed to the gh-pages branch at remote origin. The branch to push can be changed ghPages({branch: "master"}).
