## Use Gulp, Gulp Plugins and Browserify to build Angular app

This sample app use following technologies.

1. Node.js

2. Angular.js

3. Browserify

4. Gulp

5. gulp-connect

6. gulp-ng-annotate

The files structure will be following, also you can check the sample code
at [Github. After you download the code, run following command should be able to start
your app. The fisrt command will install all the node.js dependecy modules,
and second command will run the gulp task defined at
`gulpfile.js`

```
npm install -d
gulp
```

`App` folder are all the client side file for build angular app.

`Gulpfile` contains all the client side task build.

`Index.html` is the html page will be request by the client, also
contains the angular app.

`package.json` contains all the dependencies for this example.

gulp-test1

app

controllers

controller1.js
controller2.js
controller3.js

views

controller1.html
controller2.html
controller3.html

app.js

gulpfile.js
index.html
package.json

### package.json

The main module here are angular, angular-route and browserify, because
browserify will take care of angular app's dependency that's why need angular
as node module. Also, gulp and gulp's plugin modules, the gulp-np-annotate
will fix the issue when mininize js in angular, gulp-connect will run a test
app.

```
{
  "name": "gulp-test1",
  "version": "1.0.0",
  "description": "gulp-test1",
  "dependencies": {
    "angular": "^1.5.5",

    "vinyl-source-stream": "^1.1.0"
  },

}
```

### Angular App

Following is the example code use browserify with angular, broserify will take
all the dependencies for angular. For example, following code is the
`app.js` at angular.js, which define where is the controller and
views, in angualr it is useing `angular-route`, and ofcourse,
app.js is also depend on `angular.js`. In Browserify, it is very
simple to define, you just need to write, `require('angular')`,
browserify will take care the dependency for you. Similar to the angular
controllers, you'll need to define as
`require('./controllers/controller1');`.

```
'use strict';
require('angular');
require('angular-route');
var app = angular.module('gulp.test1', ['ngRoute']);

require('./controllers/controller1');
require('./controllers/controller2');
require('./controllers/controller3');

app.config(function ($routeProvider) {
    $routeProvider
       .when('/', {
        templateUrl: 'views/controller1.html',
        controller: 'controller1',
        controllerAs: 'controller1'
      })
      .when('/1', {
        templateUrl: 'views/controller2.html',
        controller: 'controller2',
        controllerAs: 'controller2'
      })
       .when('/2', {
        templateUrl: 'views/controller3.html',
        controller: 'controller3',
        controllerAs: 'controller3'
      })
      .otherwise({
        redirectTo: '/'
      });
  });
```

```
'use strict';

angular.module('gulp.test1')
  .controller('controller1', function ($scope) {
    $scope.message = 'controller1!';
});
```

```
message: {{message}}
```

#### How do I use browserify to bundle all javascript

This is sample task at gulpfile.js, at end of this task, it will create a
javascript combined all the dependency javascript. In our previous
`app.js`. It shouldn't contains angular.js angular-route.js, all
the angular controllers and the app.js itself.

```
gulp.task('browserify', function () {
    return browserify('./app/app.js')
        .bundle()
        .pipe(source('app.js'))
        .pipe(gulp.dest('./public/js/'));
});
```

### index.html

In this example, `index.html` is the actual web page, as you can
see it is any reference to the minified javascript.

```
<!doctype html>













      home](https://github.com/keke78ui9/gulp_angular_browserify_sample1)
      [main](/#1)
      [main1](/#2)



```

### gulpfile.js

```
/// setup gulp

var gulp = require('gulp');
var connect = require('gulp-connect');
// requires browserify and vinyl-source-stream
var browserify = require('browserify');
var source = require('vinyl-source-stream');
var concat = require('gulp-concat');
//var cssmin = require("gulp-cssmin");
var uglify = require("gulp-uglify");
var ngAnnotate = require('gulp-ng-annotate');

gulp.task('connect', function () {
    connect.server({
        root: 'public',
        port: 4000
    })
});

gulp.task('browserify', function () {
    // Grabs the app.js file
    return browserify('./app/app.js')
        // bundles it and creates a file called main.js
        .bundle()
        .pipe(source('app.js'))
        // saves it the public/js/ directory
        .pipe(gulp.dest('./public/js/'));
});


gulp.task("min:js", function () {

    gulp.src(["./public/js/app.js"], { base: "." })
    .pipe(ngAnnotate())
    .pipe(concat("./public/js/app.min.js"))
    .pipe(uglify())
    .pipe(gulp.dest("."));
});

gulp.task("min", ["min:js"]);

// Views task
gulp.task('views', function () {

    // Any other view files from app/views
    gulp.src('./app/views/**/*')
    // Will be put in the dist/views folder
    .pipe(gulp.dest('./public/views/'));
    // copy html to production folder
    gulp.src('./index.html').pipe(gulp.dest('./public/'));
});

gulp.task('watch', function () {
    gulp.watch('app/**/*.js', ['browserify','views']);
});

gulp.task('default', ['browserify', 'views', 'min', 'watch','connect']);
```

### Conclusion

Gulp is very powerful client side task runner, there're many different plugins
you can use, also popular IDE visual studio is also start to use gulp/grunt as
client side task runner to build assets. That means more people will start
using it and create modules for it. Also with browserify it will even become
more powerful, it use node.js to combined all client side resources.
