Setting up an Angular/Rails Single Page Application

When I started programming my very first Angular single page application (SPA), I noticed the resources for setup and integration with Devise to be thin or fragmented. The most useful guide I found was actually just a segment of a general Angular with Rails walkthrough. There were other resources that were either too complex or advanced, and they didn’t really go through the initial baby steps. One of the most daunting challenges for a new programmer is starting from scratch. I know, because I’m one of these folks.

Most of what I’ve learned through my online course has been delivered in small, increasingly more advanced components. I open a lab, and the groundwork is already laid out, so there isn’t a ton of practice in setting up an app from a blank slate. For the sake of course completion time, this makes sense. Besides, you only need to build a couple apps from the ground up to get a feel for how it’s done. If you haven’t gotten there yet, this walkthrough will be right up your alley.

Once I finally got all the pieces working and my first Angular project was up and running, I felt it pertinent to give back to the community. Since I currently don’t have enough “reputation points” to answer questions on Stack Overflow, the next best thing would be to make my own walkthrough for setting up an Angular SPA on Rails with Devise and Bootstrap. The following is exactly what I wish I had found in my initial research on the topic.

Granted, a huge part of web development is being able to solve complex problems without being handed the solution. I feel that sometimes a new developer just needs a helping hand. So here it is.

Getting Started

This guide is meant to be a diving board for getting started. It assumes you already have a basic understanding of Angular, Rails, Devise, and Bootstrap. I chose to not explore Active Record, but I do touch on Active Model Serializer, as it’s necessary for sending models to your JavaScript front end. There’s much more to learn about this subject and that would warrant its own series of guides. Likewise, I only go into installing Bootstrap to the point where I can verify it’s working.

Feel free to read along with the video I created for this tutorial:

Setting up

To get started, you want to open Terminal and navigate to the folder where you want to create your new application. In this demonstration, I’m on the Desktop.

In Terminal, you will run $ rails new YOUR-APP which initializes Rails, creates a directory with the entire framework, and bundles all of the baked in gems. (In case you’re unfamiliar, `<div class=“l-mt3 l-mh5–2col” denotes a Terminal command.)

Open your Gemfile, remove gem 'turbolinks' and add the following:


gem 'bower-rails'
gem 'devise'
gem 'angular-rails-templates' #=> allows us to place our html views in the assets/javascripts directory
gem 'active_model_serializers'
gem 'bootstrap-sass', '~> 3.3.6' #=> bootstrap also requires the 'sass-rails' gem, which should already be included in your gemfile

While Bower isn’t essential to this project, I chose to use it for one simple reason: experience. Sooner or later, I’ll probably find myself working on an app that was built with Bower, so why not start playing with it now?

What is Bower? You can learn more on their website, bower.io, but as far as I can tell, it’s essentially a package manager just like Ruby gems or npm. You can install it with npm, but I chose to include the bower-rails gem for this guide.

Initializing the Gems, Creating a Database and Adding a Migration

Now we’re going to install/initialize these gems, create our database, add a migration so users can sign up with a username, and then apply these migrations to our schema with the following commands:


$ bundle install
$ rake db:create #=> create database
$ rails g bower_rails:initialize json  #=> generates bower.json file for adding "dependencies"
$ rails g devise:install #=> generates config/initializers/devise.rb, user resources, user model, and user migration with a TON of default configurations for authentication
$ rails g migration AddUsernametoUsers username:string:uniq #=> generates, well, exactly what it says.
$ rake db:migrate

By the time you’ve got momentum building out your app, you’ll likely have many more dependencies or “packages”, but here’s what you’ll need to get started. Add the following vendor dependencies to bower.json:


...
"vendor": {
  "name": "bower-rails generated vendor assets",
  "dependencies": {
    "angular": "v1.5.8",
    "angular-ui-router": "latest",
    "angular-devise": "latest"
  }
}

Once you’ve saved those changes in bower.json, you’ll want to install those packages with the following command and then generate your user serializer from the ‘active-model-serializer’ gem installed earlier:


$ rake bower:install
$ rails g serializer user

Look for app/serializers/user_serializer.rb and add , :username directly after attributes :id so that when Devise requests the user’s information from Rails, you can display their chosen username. This is much nicer than saying “Welcome, jesse@email.com” or worse, “Welcome, 5UPer$3CREtP4SSword”. Just kidding, but seriously, don’t do that.

Add the following in config/application.rb directly under class Application < Rails::Application:


config.to_prepare do
  DeviseController.respond_to :html, :json
end

Since Angular will request information about the user using .json, we need to make sure the DeviseController will respond appropriately, which it doesn’t do by default.

Completing the Back-end Setup

We’re getting soooo close to finishing our back-end. Just a few more adjustments …

Open config/routes.rb and add the following line under devise_for :users: root 'application#index'. Then replace the contents of app/controllers/application_controller.rb with this whole snippet:


class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception
  before_action :configure_permitted_parameters, if: :devise_controller?
  skip_before_action :verify_authenticity_token

  respond_to :json

  def index
    render 'application/index'
  end

  protected

  def configure_permitted_parameters
    added_attrs = [:username, :email, :password, :password_confirmation, :remember_me]
    devise_parameter_sanitizer.permit :sign_up, keys: added_attrs
    devise_parameter_sanitizer.permit :account_update, keys: added_attrs
  end
end

We’ve done a few things here. First, we’re telling Rails that :json is our friend; our only view lives in views/application/index.html.erb; don’t worry about authenticity tokens when you get a call from Devise; oh, and our user will have a username.

Next open app/controllers/users_controller.rb and make sure you can access the user in JSON format with any /users/:id.json request:


class UsersController < ApplicationController
  def show
    user = User.find(params[:id])
    render json: user
  end  
end

Don’t worry about setting up the :show resource in routes.rb. Devise has done this for us already!

By default, Rails will initialize with views/layouts/application.html.erb, but we don’t want that (or rather, I don’t want this), so do the following:

  • Move that file to app/views/application/.
  • Rename it to index.html.erb.
  • Replace <%= yield %> with <ui-view></ui-view> (we won’t be rendering any erb aside from the script/style tags in our header).
  • Remove any mention of “turoblinks” in the script and stylesheet erb tags.
  • Add ng-app="myApp" as an attribute to the <body> tag. When we launch our server, Angular will load and frantically search our DOM for this before initializing our app.

The final step to getting our back end configured is laying out our asset pipeline. Bower has already installed a bunch of stuff for us in vendor/assets/bower_components. Likewise, we installed a bunch of sweet gems earlier. Let’s make sure our app can find these scripts and stylesheets:

Require the following in app/assets/javascripts/application.js:


//= require jquery
//= require jquery_ujs
//= require angular
//= require angular-ui-router
//= require angular-devise
//= require angular-rails-templates
//= require bootstrap-sprockets
//= require_tree .

Note: don’t forget to remove require turbolinks

Finally, we must rename app/assets/stylesheets/application.css to application.scss and add these two @import lines at the end of our stylesheet:


*
 *= require_tree .
 *= require_self
 */
@import "bootstrap-sprockets";
@import "bootstrap";

Boom!! Now we have everything set up and we can start working on our front end.

The Front End

Here’s a preview of what our Angular application tree will look like. Since we installed the ‘angular-templates’ gem, we can keep all of our HTML files in the assets/javascripts directory with all of our other Angular files:


/javascripts/controllers/AuthCtrl.js
/javascripts/controllers/HomeCtrl.js
/javascripts/controllers/NavCtrl.js
/javascripts/directives/NavDirective.js
/javascripts/views/home.html
/javascripts/views/login.html
/javascripts/views/register.html
/javascripts/views/nav.html
/javascripts/app.js
/javascripts/routes.js

First things first: let’s declare our application in app.js and inject the necessary dependencies:


(function(){
  angular
    .module('myApp', ['ui.router', 'Devise', 'templates'])
}())

I’m using an IIFE here, for reasons explained in this quote:

Wrapping your AngularJS components in an Immediately Invoked Function Expression (IIFE). This helps to prevent variables and function declarations from living longer than expected in the global scope, which also helps avoid variable collisions. This becomes even more important when your code is minified and bundled into a single file for deployment to a production server by providing variable scope for each file. Codestyle.co AngularJS Guide

Routes.js

Next, we’re going to stub out our routes.js file. Some of this is a step ahead of where we are now, but I’d rather get it out of the way now than come back:


angular
  .module('myApp')
  .config(function($stateProvider, $urlRouterProvider){
    $stateProvider
      .state('home', {
        url: '/home',
        templateUrl: 'views/home.html',
        controller: 'HomeCtrl'
      })
      .state('login', {
        url: '/login',
        templateUrl: 'views/login.html',
        controller: 'AuthCtrl',
        onEnter: function(Auth, $state){
          Auth.currentUser().then(function(){
            $state.go('home')
          })
        }
      })
      .state('register', {
        url: '/register',
        templateUrl: 'views/register.html',
        controller: 'AuthCtrl',
        onEnter: function(Auth, $state){
          Auth.currentUser().then(function(){
            $state.go('home')
          })
        }
      })
    $urlRouterProvider.otherwise('/home')
  })

What we’ve just done is called our angular app ‘myApp’, and called the config function, passing in $stateProvider and $routerUrlProvider as parameters. Immediately we can call $stateProvider and start chaining .state() methods, which take two parameters, the name of the state (‘home’ for example), and an object of data that describes the state, such as its URL, HTML template, and which controller to use. We’re also using $urlRouterProvider just to make sure that the user can’t navigate anywhere but to our predetermined states.

A few things you may not yet be familiar with up to this point are onEnter, $state, and Auth. We’ll get to that later.

Now, let’s build our home.html and HomeCtrl.js:


<div class="col-lg-8 col-lg-offset-2">
<h1>{{hello}}</h1>
<h3 ng-if="user">Welcome, {{user.username}}</h3>
</div>


angular
  .module('myApp')
  .controller('HomeCtrl', function($scope, $rootScope, Auth){
    $scope.hello = "Hello World"
  })

You may want to comment the login/register states and run $ rails s to make sure everything’s working. If it is, you’ll see a big beautiful “Hello World”. If it’s right at the top towards the middle, take a deep breath of relief, because Bootstrap is kicking in and that col-lg stuff is positioning it nicely rather than being stuck in the top left corner.

What Angular has done is searched the DOM, found the attribute ng-app, initialized “myApp”, navigated to /home by default from our router, located the <ui-view> directive, instantiated our HomeCtrl, injected the $scope object, added a key of hello, assigned it a value of "Hello World", and then rendered home.html with this information within the <ui-view> element. Once in the view, Angular scans for any meaningful commands such as the {{...}} bindings and the ng-if directive and renders the controller’s information as needed. I will admit the order of these operations may be off slightly, but you get the gist of what’s going on under the hood.

Building Out AuthCtrl.js and login.html/register.html Files

Since we’ve got all of this nitty gritty behind the scenes information out of the way, let’s build out our AuthCtrl.js and login.html/register.html files:


# login.html
<div class="col-lg-8 col-lg-offset-2">
  <h1 class="centered-text">Log In</h1>
  <form ng-submit="login()">
    <div class="form-group">
      <input type="email" class="form-control" placeholder="Email" ng-model="user.email" autofocus>
    </div>
    <div class="form-group">
      <input type="password" class="form-control" placeholder="Password" ng-model="user.password">
    </div>
    <input type="submit" class="btn btn-info" value="Log In">
  </form>
</div>


# register.html
<div class="col-lg-8 col-lg-offset-2">
  <h1 class="centered-text">Register</h1>
  <form ng-submit="register()">
    <div class="form-group">
      <input type="email" class="form-control" placeholder="Email" ng-model="user.email" autofocus>
    </div>
    <div class="form-group">
      <input type="username" class="form-control" placeholder="Username" ng-model="user.username" autofocus>
    </div>
    <div class="form-group">
      <input type="password" class="form-control" placeholder="Password" ng-model="user.password">
    </div>
    <input type="submit" class="btn btn-info" value="Log In">
  </form>
  <br>

  <div class="panel-footer">
    Already signed up? <a ui-sref="home.login">Log in here</a>.
  </div>
</div>

Before I overwhelm you with the AuthCtrl, I just want to point out that most of what you’re seeing are Bootstraped CSS classes so that you’re all super impressed with how beautifully this renders. Ignore all of the class attributes, and everything else should be pretty familiar, such as ng-submit, ng-model, and ui-sref, which takes the places of our usual href anchor tag attribute. Now for the AuthCtrl … are you ready?


angular
  .module('myApp')
  .controller('AuthCtrl', function($scope, $rootScope, Auth, $state){
    var config = {headers: {'X-HTTP-Method-Override': 'POST'}}

    $scope.register = function(){
      Auth.register($scope.user, config).then(function(user){
        $rootScope.user = user
        alert("Thanks for signing up, " + user.username);
        $state.go('home');
      }, function(response){
        alert(response.data.error)
      });
    };

    $scope.login = function(){
      Auth.login($scope.user, config).then(function(user){
        $rootScope.user = user
        alert("You're all signed in, " + user.username);
        $state.go('home');
      }, function(response){
        alert(response.data.error)
      });
    }
  })

Most of this code is derived from the Angular Devise documentation, so I won’t go into too much detail. What you need to know now is that Auth is the service created by angular-device, and it comes with some pretty awesome functions, such as Auth.login(userParameters, config) and Auth.register(userParameters, config). These create a promise, which returns the logged in user once resolved.

I’ll admit that I’ve cheated a bit here and assigned that user to the $rootScope. However, a better performing, more scalable approach would be to create a UserService, store the user there, and then inject UserService into any of your controllers that need the user. For the sake of brevity, I also used a simple alert() function in lieu of integrating ngMessages or another service like ngFlash to make announcements about errors or successful login events.

The rest should be pretty self explanatory. The ng-submit forms are attached to these $scope functions, $scope.user is pulling the information from the ng-models on the form inputs, and $state.go() is a nifty function for redirecting to another state.

If you go back to routes.js now, all of that onEnter logic should make a lot more sense.

Bringing It All Together

I saved the best for last, so let’s build a fancy little NavDirective.js and nav.html to bring everything together:


angular
  .module('myApp')
  .directive('navBar', function NavBar(){
    return {
      templateUrl: 'views/nav.html',
      controller: 'NavCtrl'
    }
})


<div class="col-lg-8 col-lg-offset-2">
  <ul class="nav navbar-nav" >
    <li><a ui-sref="home">Home</a></li>
    <li ng-hide="signedIn()"><a ui-sref="login">Login</a></li>
    <li ng-hide="signedIn()"><a ui-sref="register">Register</a></li>
    <li ng-show="signedIn()"><a ng-click="logout()">Log Out</a></li>
  </ul>
</div>

And the more robust NavCtrl.js:


angular
  .module('myApp')
  .controller('NavCtrl', function($scope, Auth, $rootScope){
    $scope.signedIn = Auth.isAuthenticated;
    $scope.logout = Auth.logout;

    Auth.currentUser().then(function (user){
      $rootScope.user = user
    });

    $scope.$on('devise:new-registration', function (e, user){
      $rootScope.user = user
    });

    $scope.$on('devise:login', function (e, user){
      $rootScope.user = user
    });

    $scope.$on('devise:logout', function (e, user){
      alert("You have been logged out.")
      $rootScope.user = undefined
    });
  })

All we’re doing here is setting up the functions to use in the navigation links such as ng-hide="signedIn()" and ng-click="logout()" and adding listeners to the $scope so that we can trigger actions when certain devise specific events occur. We’re also calling Auth.currentuser() so that when this controller is instantiated, we can double check our $rootScope.user object and display the proper nav links.

Let’s find app/views/application/index.html again and add <nav-bar></nav-bar> on the line above <ui-view>. Since this isn’t tied to any of the routes, it will always render above our main content.

Go ahead and refresh your page now. Don’t you love it when things just work? Hopefully you don’t have any weird issues with an out of date bundle, version of Ruby, or something funky like that. Just remember, Google is your best friend.

Anyhoo, I hope this has helped! Please leave any questions, comments, or suggestions below!

Install Angular - Angular Environment Setup Process

Angular is a TypeScript based framework that works in synchronization with HTML, CSS, and JavaScript. To work with angular, domain knowledge of these 3 is required.

  1. Installing Node.js and npm
  2. Installing Angular CLI
  3. Creating workspace
  4. Deploying your First App

In this article, you will get to know about the Angular Environment setup process. After reading this article, you will be able to install, setup, create, and launch your own application in Angular. So let’s start!!!

Angular environment setup

Install Angular in Easy Steps

For Installing Angular on your Machine, there are 2 prerequisites:

  • Node.js
  • npm Package Manager
Node.js

First you need to have Node.js installed as Angular require current, active LTS or maintenance LTS version of Node.js

Download and Install Node.js version suitable for your machine’s operating system.

Npm Package Manager

Angular, Angular CLI and Angular applications are dependent on npm packages. By installing Node.js, you have automatically installed the npm Package manager which will be the base for installing angular in your system. To check the presence of npm client and Angular version check of npm client, run this command:

  1. npm -v

Installing Angular CLI

  • Open Terminal/Command Prompt
  • To install Angular CLI, run the below command:
  1. npm install -g @angular/cli

installing angular CLI

· After executing the command, Angular CLI will get installed within some time. You can check it using the following command

  1. ng --version

Workspace Creation

Now as your Angular CLI is installed, you need to create a workspace to work upon your application. Methods for it are:

  • Using CLI
  • Using Visual Studio Code
1. Using CLI

To create a workspace:

  • Navigate to the desired directory where you want to create your workspace using cd command in the Terminal/Command prompt
  • Then in the directory write this command on your terminal and provide the name of the app which you want to create. In my case I have mentioned DataFlair:
  1. Ng new YourAppName

create angular workspace

  • After running this command, it will prompt you to select from various options about the CSS and other functionalities.

angular CSS options

  • To leave everything to default, simply press the Enter or the Return key.

Wondering how to upgrade your skills in the pandemic? Here's a simple way you can do it.

Corona Virus Pandemic has brought the world to a standstill.

Countries are on a major lockdown. Schools, colleges, theatres, gym, clubs, and all other public places are shut down, the country’s economy is suffering, human health is on stake, people are losing their jobs and nobody knows how worse it can get.

Since most of the places are on lockdown, and you are working from home or have enough time to nourish your skills, then you should use this time wisely! We always complain that we want some ‘time’ to learn and upgrade our knowledge but don’t get it due to our ‘busy schedules’. So, now is the time to make a ‘list of skills’ and learn and upgrade your skills at home!

And for the technology-loving people like us, Knoldus Techhub has already helped us a lot in doing it in a short span of time!

If you are still not aware of it, don’t worry as Georgia Byng has well said,

“No time is better than the present”

– Georgia Byng, a British children’s writer, illustrator, actress and film producer.

No matter if you are a developer (be it front-end or back-end) or a data scientisttester, or a DevOps person, or, a learner who has a keen interest in technology, Knoldus Techhub has brought it all for you under one common roof.

From technologies like Scala, spark, elastic-search to angular, go, machine learning, it has a total of 20 technologies with some recently added ones i.e. DAML, test automation, snowflake, and ionic.

How to upgrade your skills?

Every technology in Tech-hub has n number of templates. Once you click on any specific technology you’ll be able to see all the templates of that technology. Since these templates are downloadable, you need to provide your email to get the template downloadable link in your mail.

Why should we use Ruby on Rails for Software Development?

What is Rails, Ruby on Rails?

Rails is a server-side web application development framework written in the Ruby programming language. Its emergence in 2005 has influenced and impacted web application development to a vast range, including but not limited to seamless database tables, migrations, and scaffolding of views. In the simplest understanding, Rails is a highly productive and intuitive software developer. 

Websites and applications of any complexity can be achieved with Ruby on Rails. The software is designed to perceive the needs of ruby on rails developers and encourage them with the best way out. It is designed to allow developers to write lesser code while spiking productivity much more than any other framework or language. Ruby on Rails rapid application development offers everyday web development tasks easier and uniquely out-of-the-box, both with the same effectiveness.

The Ruby on Rails framework is based on two philosophies:

 

  • Don’t Repeat Yourself (DRY): It is a software development principle that ensures that every piece or entity of knowledge must be assigned with a single and unambiguous representation within a development system.

    It not only reduces the need to write lengthy codes but also eliminates the repetitive writing of codes. As a result, it provides a much more manageable web app development with the least possible bugs.

 

  • Convention over Configuration (CoC): It indicates the highly opinionated feature that the Ruby on Rails framework possesses. It offers ready-made solutions or the “best way out” for many tasks in a web application and defaults them to the convention without the need for external specification. The programmer using the software is required to specify only the unconventional aspects of the web application. 

Some of the commonly known websites built by the Ruby on Rails software developers are Instacart, Scribd, Shopify, Github, ConvertKit, Soundcloud, GoodReads, Airbnb. It finds its application in Sa-as Solutions, Social Networking Platforms, Dating websites, Stock Exchange Platforms, etc.

Why use Ruby on Rails: The multifold benefits

  • Community and its abundant resources 

    • There is a large community that is dedicated to Ruby on Rails that keeps it up-to-date and indeed encourages its family of developers to continue using it. They make sure the benefits are soaring with every update they make. 

    • The community is committed to developing several ready-to-use code packages, commonly known as gems, for its users. They discuss and announce new project launches, help each other with queries, and engage in framework discussions and betterment. While Ruby on Rails helps developers in rapid application development, it also connects and grows businesses together.

  • Project Scalability

    • To talk about scalability, we indicate the ability to grow and manage more and more user requests per minute (RPM). However, this depends on the architecture rather than the framework. The right architecture of Ruby on Rails web application development allows it to write bulky codes and programs as compared to early-stage difficulties with scalability. 

    • It uses the Representational State Transfer (REST) architecture. This will enable Rails to create efficient web applications based on Rails 6, launched last year in 2020, which addresses most scalability issues. The portable components are agile and help in a better understanding of new requirements and needful adaptations for any business. The framework and architecture allow both vertical and horizontal scalability.

  • Fast Application Development and Cost Effectiveness

    • Ruby on Rails is lucid, logical, and has lean code requirements, thereby cutting down redundancy and improving the overall development speed.
