Script for deploying ASP.NET MVC 6 website to Azure

Let's separate topics first.

For deploying a Web app to Azure, why not use Continuous Integration? If you link your Web App with your repository, you can pick a branch and everytime you push to that branch, it gets deployed on Azure.

You can go a step further and configure Deployment Slots (a staging one in particular) and configure Auto-Swap to reduce Cold starts.

For Javascript minification, you can just use Gulp/Grunt with tasks that either, run on your development environment (and you commit to your repository the minified output) or you can run the tasks as a "postrestore" action defined in your project.json file. A simple:

{
  "scripts": {
    "postrestore": ["npm install", "bower install","gulp default"]
  }
}

Will do the trick by pulling your defined bower packages and then running the default gulp task.

Your default gulp task can be something like:

var gulp = require('gulp');  
var mainBowerFiles = require('main-bower-files');
var bower = require('gulp-bower');  
var uglify = require('gulp-uglify');
var ignore = require('gulp-ignore');
var del = require('del');

var project = require('./project.json');  
var lib = project.webroot + '/dist'; 

gulp.task('clean',function(done){
    del(lib, done);
});

gulp.task('bower:install', ['clean'], function () {  
    return bower();
});

gulp.task('default', ['bower:install'], function () {  
    return gulp.src(mainBowerFiles())
        .pipe(ignore.exclude([ "**/*.css","**/*.less" ]))
      .pipe(uglify())
      .pipe(gulp.dest(lib+'/js'));
});
