SASS is a

CSS preprocessor

a layer between the stylesheets you author and the .css files you serve to the browser

Nesting

Sass will let you nest your CSS selectors in a way that follows the same visual hierarchy of your HTML.

nav ul {
  margin: 0;
  padding: 0;
  list-style: none;
}

nav li {
  display: inline-block;
}

nav a {
  display: block;
  padding: 6px 12px;
  text-decoration: none;
}

nav {
  ul {
    margin: 0;
    padding: 0;
    list-style: none;
  }

  li { display: inline-block; }

  a {
    display: block;
    padding: 6px 12px;
    text-decoration: none;
  }
}

@Import

Instead of requiring an HTTP request, Sass will take the file that you want to import and combine it with the file you're importing into so you can serve a single CSS file to the web browser.

// Modules and Variables
@import "partials/base";

// Partials
@import "partials/reset";
@import "partials/typography";
@import "partials/buttons";
@import "partials/figures";
@import "partials/grids";
// ...

// Third-party
@import "vendor/colorpicker";
@import "vendor/jquery.ui.core";

Basic directory structire

|
|-- modules/              # Common modules
|   |-- _all.scss         # Include to get all modules
|   |-- _utility.scss     # Module name
|   |-- _colors.scss      # Etc...
|   ...

|   |-- _figures.scss     # figures
|   |-- _grids.scss       # grids
|   |-- _typography.scss  # typography
|   |-- _reset.scss       # reset
|   ...
|
|-- vendor/               # CSS or Sass from other projects
|   |-- _colorpicker.scss
|   |-- _jquery.ui.core.scss
|   ...
|
`-- main.scss            # primary Sass file

Extend

Using @extend lets you share a set of CSS properties from one selector to another. It helps keep your Sass very DRY.

.message {
  border: 1px solid #ccc;
  padding: 10px;
  color: #333;
}

.success {
  @extend .message;
  border-color: green;
}

.error {
  @extend .message;
  border-color: red;
}

.warning {
  @extend .message;
  border-color: yellow;
}

.message, .success, .error, .warning {
  border: 1px solid #cccccc;
  padding: 10px;
  color: #333;
}

.success {
  border-color: green;
}

.error {
  border-color: red;
}

.warning {
  border-color: yellow;
}

Bower

Web sites are made of lots of things — frameworks, libraries, assets, and utilities. Bower manages all these things for you.

Installation

Bower is a command line utility. Install it with npm.

Bower requires node, npm and git.

$ npm install -g bower

Install packages

Install packages with bower install. Bower installs packages to bower_components/.

$ bower install <package>

# installs the project dependencies listed in bower.json
$ bower install
# registered package
$ bower install jquery
# GitHub shorthand
$ bower install desandro/masonry
# Git endpoint
$ bower install git://github.com/user/package.git
# URL
$ bower install http://example.com/script.js

Save packages

Create a bower.json file for your package with bower init.

Then save new dependencies to your bower.json with bower install PACKAGE --save

Use packages

<script src="bower_components/jquery/dist/jquery.min.js"></script>

Gulp

Is a javascript task runner tool that helps you out with several tasks when it comes to web development. It's often used to do front end tasks like:

Spinning up a web server.
Reloading the browser automatically whenever a file is saved.
Using preprocessors like Sass or LESS.
Optimizing assets like CSS, JavaScript, and images.
Quickly running unit tests
Running code analysis

The Gulp workflow

Below is a common workflow for performing certain build operations.

Define a task
Within that task, a desired set of files are loaded into the gulp stream to be processed. (Optional) Once files are in the stream, one or more modifications can be made to the files. Because the streams are processed in memory, no file - system writes to temporary directories between modifications are required.
Send the new (possibly modified) files to a specified destination

Installation

You need to have Node.js (Node) installed onto your computer before you can install Gulp.

$ sudo npm install gulp -g

$ npm install gulp --save-dev

Now, let's begin by creating your first Gulp task in gulpfile.js, which stores all Gulp configurations.

var gulp = require('gulp');
// Requires the gulp-sass plugin
var sass = require('gulp-sass');

gulp.task('sass', function(){
  return gulp.src('app/scss/styles.scss')
    .pipe(sass()) // Converts Sass to CSS with gulp-sass
    .pipe(gulp.dest('app/css'))
});

Preprocessing

$ npm install gulp-sass --save-dev

Gulp provides us with a watch method that checks to see if a file was saved. The syntax for the watch method is:

gulp.task('watch', function(){
  gulp.watch('app/scss/**/*.scss', ['sass']); 
  // Other watchers
})

Watch files

// Gulp watch syntax
gulp.watch('app/scss/**/*.scss', ['sass']);

Browser Sync helps make web development easier by spinning up a web server that helps us do live-reloading easily.

Live realoading

$ npm install browser-sync --save-dev

var browserSync = require('browser-sync').create();

gulp.task('server', function() {
  browserSync.init({
    server: {
      baseDir: 'app'
    },
  })
})

gulp.task('sass', function(){
  return gulp.src('app/scss/styles.scss')
    .pipe(sass()) // Converts Sass to CSS with gulp-sass
    .pipe(gulp.dest('app/css'))
    //Aditional pipe
    .pipe(server.reload({
      stream: true
    }))
});

// Default Task
gulp.task('default', ['server', 'sass']);

Core & Plugins

// Include gulp
var gulp = require('gulp');

// Include Our Plugins
var eslint = require('gulp-eslint');
var sass = require('gulp-sass');
var concat = require('gulp-concat');
var uglify = require('gulp-uglify');
var rename = require('gulp-rename');

What's Yeoman?

Yeoman helps you to kickstart new projects, prescribing best practices and tools to help you stay productive.

To do so, we provide a generator ecosystem. A generator is basically a plugin that can be run with the `yo` command to scaffold complete projects or useful parts.

Tools

The Yeoman workflow comprises three types of tools for improving your productivity and satisfaction when building a web app: the scaffolding tool (yo), the build tool (Gulp, Grunt etc) and the package manager (like npm and Bower).

Installation

npm install -g yo

Generators

Usage

npm install --global generator-webapp

Install generator

yo webapp

Run generator

Run & build aplication

Run gulp serve to preview and watch for changes
Run bower install --save <package> to install frontend dependencies
Run gulp serve:test to run the tests in the browser
Run gulp to build your webapp for production
Run gulp serve:dist to preview the production build

AngularJS

Is a structural frameworks for dynamic web apps

Why use Angular?

Reusable components.
100% javascript and client side.
Single page apps (UX Desktop apps).
MVC architecture.
Two way data binding

Directory structure

----- controllers/
---------- mainController.js
---------- otherController.js
----- directives/
---------- mainDirective.js
---------- otherDirective.js
----- services/
---------- userService.js
---------- itemService.js
----- js/
---------- bootstrap.js
---------- jquery.js
----- app.js
views/
----- mainView.html
----- otherView.html
----- index.html

Standart

app/
----- shared/   // acts as reusable components or partials of our site
---------- sidebar/
--------------- sidebarDirective.js
--------------- sidebarView.html
---------- article/
--------------- articleDirective.js
--------------- articleView.html
----- components/   // each component is treated as a mini Angular app
---------- home/
--------------- homeController.js
--------------- homeService.js
--------------- homeView.html
---------- blog/
--------------- blogController.js
--------------- blogService.js
--------------- blogView.html
----- app.module.js
----- app.routes.js
assets/
----- img/      // Images and icons for your app
----- css/      // All styles and style related files (SCSS or LESS files)
----- js/       // JavaScript files written for your app that are not for angular
----- libs/     // Third-party libraries such as jQuery, Moment, Underscore, etc.
index.html

Modularized

Basic set up

<div ng-app="myApp">
    <div ng-controller="MainCtrl">
         {{ text }}
    </div>
</div>

var myApp = angular.module('myApp', []);

myApp.controller('MainCtrl', ['$scope', function ($scope) {
    
    $scope.text = 'Hello, Angular fanatic.';
    
}]);

Directives

<button ng-click="runWhenButtonClicked()"></button>
<div ng-click="runWhenDivClicked()"></div>

$scopes

<div ng-controller='mainController'>
    <p>{{ name }}</p>
    <input type="text" ng-model="email">
</div>

VIEW

.controller('mainController', function($scope){
  $scope.name = "Daniel";
  $scope.email = "";
});

MODEL

Dynamic views and routing

app.config(['$routeProvider', function ($routeProvider) {
  /**
   * $routeProvider
   */
  $routeProvider
  .when('/', {
    templateUrl: 'views/main.html'
  })
  .when('/emails', {
    templateUrl: 'views/emails.html'
  })
  .otherwise({
    redirectTo: '/'
  });
}])

Funtions & http request

VIEW

<div ng-controller='UserCtrl'>
    <p>{{ user.username }}</p>
    <button type="text" ng-click="getUsername()">Get username</button>
</div>

myApp.controller('UserCtrl', ['$scope', '$http', function ($scope, $http) {

  // create a user Object
  $scope.user = {};

  // Initiate a model as an empty string
  $scope.user.username = '';
  
  $scope.getUsername = function(){
    
  // We want to make a call and get
  // the person's username
    $http({
        method: 'GET',
        url: '//localhost:9000/someUrlForGettingUsername'
      })
      .success(function (data, status, headers, config) {
        // See here, we are now assigning this username
        // to our existing model!
        $scope.user.username = data.user.name;
      })
      .error(function (data, status, headers, config) {
        // something went wrong :(
      });        
  };
}]);
