Gulp equivalent of grunt for VS2015 web template

gulpfile.js

var gulp = require('gulp');
var mainBowerFiles = require('main-bower-files');
var $ = require('gulp-load-plugins')({
    lazy: true
});

gulp.task('bower', function () {
    return $.bower()
});

gulp.task('default', ['bower'], function () {
    return gulp.src(mainBowerFiles())
        .pipe(gulp.dest("wwwroot/lib"));
});

package.json

{
    "version": "0.0.0",
    "name": "TestWebApp",
    "devDependencies": {
        "del": "^1.1.1",
        "gulp": "^3.8.10",
        "gulp-bower": "0.0.10",
        "gulp-load-plugins": "^0.8.1",
        "main-bower-files": "^2.5.0"
    }
}

You should chuck rimraf. It's an external package that effectively does what node does out of the box with del. Use require('del') instead.

The bower wire-up is messy and error prone (magic strings). I recommend using wiredep here as it "just works" and works even when you add more bower files. Happy to help contribute if you want.

as a side note, if you want a default gulpfile, happy to help there too.
