Extends Ionics' default Gulp.js with a scripts & bower-files task. Moves app/ source outside the www folder.

Ionic gulp

var gulp = require('gulp');
var concat = require('gulp-concat');
var sass = require('gulp-sass');
var minifyCss = require('gulp-minify-css');
var rename = require('gulp-rename');
var gulpBowerFiles = require('gulp-bower-files');

var paths = {
  sass: ['./scss/**/*.scss'],
  scripts: ['./app/**/*.js', './app/*.js']
};

gulp.task("bower-files", function(){
    gulpBowerFiles().pipe(gulp.dest("./www/lib"));
});

gulp.task('sass', function(done) {
  gulp.src('./scss/ionic.app.scss')
    .pipe(sass())
    .pipe(gulp.dest('./www/css/'))
    .pipe(minifyCss({
      keepSpecialComments: 0
    }))
    .pipe(rename({ extname: '.min.css' }))
    .pipe(gulp.dest('./www/css/'))
    .on('end', done);
});

gulp.task('scripts', function(done) {
  gulp.src(['./app/*.js', './app/**/*.js'])
   .pipe(concat('app.js'))
   .pipe(gulp.dest('./www/js'))
   .on('end', done);
});

gulp.task('watch', function() {
  gulp.watch(paths.sass, ['sass']);
  gulp.watch(paths.scripts, ['bower-files', 'scripts']);
});

gulp.task('default', ['sass']);
