angular-2-afternoon's Introduction

Project Summary

In this project, you will finish an Angular travel application. You will setup the routes and sub routes for the application as well as practice the fundamentals of Angular some more.

Live Example

Click Me!

Setup

  • Fork and clone this repository
  • cd into the project directory.
  • Run npm install.
  • After npm install, run npm run dev.
    • Go to provided URL by live-server in your browser if it doesn't automatically open a browser window.

Step 1

Summary

In this step, you'll familarize yourself with the existing code base. Pay attention to file structure and what code is already created for you. The Angular application and first route have been created in app/app.js. There is also a service file ( app/mainSrvc.js ) that is given to you. There are also various controllers and templates already created throughout the app folder.

Instructions

  • Take as much time as you need to familiarize yourself with the project.

Step 2

Summary

In this step, we'll configure the router to handle all the other provided templates. The over provided templates are located in the feature folders ( about, booked, locations, packages ) in app/.

Instructions

  • Open app/app.js.
  • Add the following new routes to the config:
    • Name: packages - Url: /packages/:country - Template: app/packages/packagesTmpl.html.
    • Name: locations - Url: /locations - Template: app/locations/locationsTmpl.html.
    • Name: booked - Url: /booked/:id - Template: app/booked/bookedTmpl.html.
    • Name: adventurers - Url: /adventurers - Template: app/about/adventurers/adventurersTmpl.html.
      • This route should be a sub-route of the home page.
    • Name: contact - Url: /contact - Template: app/contact/contactTmpl.html.
      • This route should be a sub-route of the home page.
Detailed Instructions

Let's begin by opening app/app.js. In order for a user to navigate our Angular application, we'll need to add the remaining views into our router configuration. We can add more routes to our configuration by chaining on more .states. All our additions will look similiar except for adventurers and contact. These routes will also include a parent property. The parent property is what distinguishes a sub-route from a route. We'll assign the parent as home to make them sub-routes of home.

Let's add a route for packages by chaining on another .state:

  $stateProvider
    .state('home',{
      url:'/',
      templateUrl: 'app/about/aboutTmpl.html'
    })
    .state('packages', {
      url: '/packages/:country',
      templateUrl: 'app/packages/packagesTmpl.html'
    })

This would look the same for locations and booked:

  $stateProvider
    .state('home',{
      url:'/',
      templateUrl: 'app/about/aboutTmpl.html'
    })
    .state('packages', {
      url: '/packages/:country',
      templateUrl: 'app/packages/packagesTmpl.html'
    })
    .state('locations', {
      url: '/locations',
      templateUrl: 'app/locations/locationsTmpl.html'
    })
    .state('booked', {
      url: '/booked/:id',
      templateUrl: 'app/booked/bookedTmpl.html'
    })

And then finally we can add the route for adventurers and contact which will have a parent of home:

  $stateProvider
    .state('home',{
      url:'/',
      templateUrl: 'app/about/aboutTmpl.html'
    })
    .state('packages', {
      url: '/packages/:country',
      templateUrl: 'app/packages/packagesTmpl.html'
    })
    .state('locations', {
      url: '/locations',
      templateUrl: 'app/locations/locationsTmpl.html'
    })
    .state('booked', {
      url: '/booked/:id',
      templateUrl: 'app/booked/bookedTmpl.html'
    })
    .state('adventurers', {
      url: '/adventurers',
      templateUrl: 'app/about/adventurers/adventurersTmpl.html',
      parent: 'home'
    })
    .state('contact', {
      url: '/contact',
      templateUrl: 'app/about/contact/contactTmpl.html',
      parent: 'home'
    });

Solution

app/app.js 
angular.module('devmtnTravel', ['ui.router']).config( function ( $stateProvider, $urlRouterProvider ) {
  $stateProvider
    .state('home',{
      url:'/',
      templateUrl: 'app/about/aboutTmpl.html'
    })
    .state('packages', {
      url: '/packages/:country',
      templateUrl: 'app/packages/packagesTmpl.html'
    })
    .state('locations', {
      url: '/locations',
      templateUrl: 'app/locations/locationsTmpl.html'
    })
    .state('booked', {
      url: '/booked/:id',
      templateUrl: 'app/booked/bookedTmpl.html'
    })
    .state('adventurers', {
      url: '/adventurers',
      templateUrl: 'app/about/adventurers/adventurersTmpl.html',
      parent: 'home'
    })
    .state('contact', {
      url: '/contact',
      templateUrl: 'app/about/contact/contactTmpl.html',
      parent: 'home'
    });

  $urlRouterProvider
    .otherwise('/');
});

Step 3

Summary

In this step, we'll create Angular controllers for locations, packages, and booked. We'll then assign the new controllers to our router configuration.

Instructions

  • Create a new controller file in:
    • app/locations/.
    • app/packages/.
    • app/booked/.
  • Open index.html.
  • Add script tags for each new controller in index.html.
  • Open app/app.js.
  • Assign the locationCtrl to the locations route.
  • Assign the packagesCtrl to the packages route.
  • Assign the bookedCtrl to the booked route.
Detailed Instructions

Let's begin by creating an empty controller file in app/locations/, app/packages/, and app/booked/. The file names I chose to use were locationsCtrl.js, packagesCtrl.js, and bookedCtrl.js. Inside each of these files, we can create an empty controller file for the devmtnTravel Angular application.

angular.module('devmtnTravel').controller('controllerName', function( $scope ) {

});

Be sure to replace controllerName with the name of the controller. I used these names: locationsCtrl, packagesCtrl, and bookedCtrl. Now that our controllers are created, we'll need to import them into index.html. Let's add three script tags underneath <!--Our Custom Script Files-->.

<script src="app/locations/locationsCtrl.js"></script>
<script src="app/packages/packagesCtrl.js"></script>
<script src="app/booked/bookedCtrl.js"></script>

We can then assign these controllers to routes in our router configuration. We'll assign locationCtrl to the locations route, packagesCtrl to the packages route, and bookedCtrl to the booked route.

.state('packages', {
  url: '/packages/:country',
  templateUrl: 'app/packages/packagesTmpl.html',
  controller: 'packagesCtrl'
})
.state('locations', {
  url: '/locations',
  templateUrl: 'app/locations/locationsTmpl.html',
  controller: 'locationsCtrl'
})
.state('booked', {
  url: '/booked/:id',
  templateUrl: 'app/booked/bookedTmpl.html',
  controller: 'bookedCtrl'
})

Solution

app/locations/locationCtrl.js 
angular.module('devmtnTravel').controller('locationsCtrl', function( $scope ) {

});
app/packages/packagesCtrl.js 
angular.module('devmtnTravel').controller('packagesCtrl', function( $scope ) {

});
app/booked/bookedCtrl.js 
angular.module('devmtnTravel').controller('bookedCtrl', function( $scope ) {

});

      parent: 'home'
    });

  $urlRouterProvider
    .otherwise('/');
});

Step 4

Summary

In this step, we'll test the controllers we just made to make sure everything is hooked up correctly.

Instructions

  • Inside each controller we made in the previous step, add a new $scope variable called test and set it equal to some string.
  • Open all three template files ( locationsTmpl.html, packagesTmpl.html, bookedTmpl.html ):
    • Add {{ test }} somewhere in the HTML.
  • In your browser, using the address bar, manually go to each route and make sure $scope.test is appearing on the DOM.
  • Once you can successfully see the value of $scope.test on each view:
    • Remove {{ test }} from each template HTML file.
    • Remove $scope.test from each controller file.

Solution

Step 5

Summary

In this step, we'll hook up the ui-sref's in the template HTML files to allow the user to navigate the application. Since there are comments in the code file themselves, there wont be any detailed instructions on this step.

Instructions

  • Open each template HTML file and locate the comment explaining the ui-sref.
    • Don't worry about the id and country for the booked and packages route in this step.
  • Open index.html.
  • Locate the <!--Navigation Section--> comment.
    • Add ui-sref tags to the correct view.
      • Locations should route to locations.
      • Packages should route to packages.
      • The logo shouldn't have a route.
      • About should route to home.
      • Contact should route to contact.

Step 6

Summary

In this step, we'll setup the mainSrvc to call on a live API for travel and package data and then add it to the list of scripts in index.html.

API Documentation

  • GET - https://practiceapi.devmountain.com/api/travel/travel-info:
    • Returns an array of travel objects. Travel objects contain the following properties:
      • country - String.
      • image - String ( a filepath to a specific image in the img/ folder ).
      • desc - String.
      • price - Number.
  • GET - https://practiceapi.devmountain.com/api/travel/package-info:
    • Returns an array of package objects. Package objects contain the following properties:
      • city - String.
      • country - String.
      • desc - String.
      • id - Number.
      • image - String ( a filepath to a specific image in the img/ folder ).
      • price - Number.

Instructions

  • Open app/mainSrvc.js.
  • Inject $http into the service.
  • Create two methods on the service:
    • Each method should return a promise of a $http get call.
    • Use the API documentation above for help.
    • Use the following names for your methods: getTravelInfo and getPackageInfo.
  • Add app/mainSrvc.js as a new script in index.html.
Detailed Instructions

Let's begin by opening app/mainSrvc.js and injecting $http into it. This will allow us to make API calls.

angular.module('devmtnTravel').service('mainSrvc', function( $http ) {

}

We'll need two methods in this service. One for hitting the travel-info endpoint and one for hitting the package-info endpoint. The travel-info endpoint will give us the data we'll need to populate the locations template and the package-info endpint will give us the data we'll need to populate the packages template. Let's start by just creating the skeleton of the two methods. We'll be using the names getTravelInfo and getPackageInfo for them.

angular.module('devmtnTravel').service('mainSrvc', function( $http ) {
  this.getTravelInfo = function() {
    
  }

  this.getPackageInfo = function() {

  }
}

We want to design these methods so they return a promise. This will allow us to do asynchronous code in the controllers. Luckily, $http can do this for us. When calling $http it automagically returns a promise. Knowing this, we can have our functions return the $http call. Using the API documentation above, we know we need to make a GET call on the following URLs: https://practiceapi.devmountain.com/api/travel/travel-info and https://practiceapi.devmountain.com/api/travel/package-info:

angular.module('devmtnTravel').service('mainSrvc', function( $http ) {
  this.getTravelInfo = function() {
    return $http({
      method: 'GET',
      url: 'https://practiceapi.devmountain.com/api/travel/travel-info'
    });
  };

  this.getPackageInfo = function() {
    return $http({
      method: 'GET',
      url: 'https://practiceapi.devmountain.com/api/travel/package-info'
    });
  };
});

Now that the service is completed, let's add it into index.html so our controllers will be able to inject and use it.

<script src="app/mainSrvc.js"></script>

Solution

app/mainSrvc.js 
angular.module('devmtnTravel').service('mainSrvc', function( $http ) {
  this.getTravelInfo = function() {
    return $http({
      method: 'GET',
      url: 'https://practiceapi.devmountain.com/api/travel/travel-info'
    });
  };

  this.getPackageInfo = function() {
    return $http({
      method: 'GET',
      url: 'https://practiceapi.devmountain.com/api/travel/package-info'
    });
  };
});

Step 7

Summary

In this step, we'll complete the booked feature. The booked feature is designed to work by getting an id from the URL. It will then find the corresponding package object with the same id and assign that object on $scope.

Instructions

  • Open app/booked/bookedTmpl.html and app/booked/bookedCtrl.js.
  • Inside of bookedCtrl.js:
    • Inject $stateParams into the controller.
    • Inject mainSrvc into the controller.
    • Call the getPackageInfo method and catch the response:
      • Assign a new $scope variable called allPackages that equals the response's data.
      • Find the package object with the id that matches the id on $stateParams:
        • Assign it to a new $scope variable called package.
  • Inside of bookedTmpl.html:
    • Add an ng-if to the most parent element that equals "package".
    • Display the package's city followed by the package's country in the h1 element.
      • Example: Bordeaux, France
    • Add an ng-style to the parent section element:
      • Set the background-image to the value of image on the package object.
    • Fix the ui-sref to include a country parameter that equals the package's country.
Detailed Instructions

Let's begin by opening app/booked/bookedCtrl.js and get the data we need from mainSrvc. To do this we'll need to inject mainSrvc and then call its getPackageInfo method. We'll then want to capture its response and put our async logic inside of there. The first thing we'll want to do is assign $scope.allPackages to the response's data.

angular.module('devmtnTravel').controller('bookedCtrl', function( $scope, mainSrvc ) {
  mainSrvc.getPackageInfo().then( function( response ) {
    $scope.allPackages = response.data;
  });
});

Using this packages array, we can search through it and find the package object that has the same id as the id in the URL. In order to be able to read the id from the URL, we'll need to inject $stateParams into the controller.

angular.module('devmtnTravel').controller('bookedCtrl', function( $scope, $stateParams, mainSrvc ) {
  mainSrvc.getPackageInfo().then( function( response ) {
    $scope.allPackages = response.data;
  });
});

Alright, time for some logic. We now have access to $stateParams.id ( the id in the URL ) and the packages array ( $scope.allPackages ). We can add an if statement to check if the page was loaded with an id in the URL. If it was, we can get the index of the package object in $scope.allPackages by using the findIndex Array method.

angular.module('devmtnTravel').controller('bookedCtrl', function( $scope, $stateParams, mainSrvc ) {
  mainSrvc.getPackageInfo().then( function( response ) {
    $scope.allPackages = response.data;

    if ( $stateParams.id ) {
      $scope.packageIndex = $scope.allPackages.findIndex( function( package ) {
        return package.id === parseInt( $stateParams.id );
      }); 
    }
  });
});

$scope.packageIndex will either be assigned the index of the package object in $scope.allPackages or -1 if it is not found in the array. We can use this as another conditional to assign a new $scope variable called $scope.package.

angular.module('devmtnTravel').controller('bookedCtrl', function( $scope, $stateParams, mainSrvc ) {
  mainSrvc.getPackageInfo().then( function( response ) {
    $scope.allPackages = response.data;

    if ( $stateParams.id ) {
      $scope.packageIndex = $scope.allPackages.findIndex( function( package ) {
        return package.id === parseInt( $stateParams.id );
      }); 
  
      if ( $scope.packageIndex !== -1 ) {
        $scope.package = $scope.allPackages[ $scope.packageIndex ];
      }
    }
  });
});

Now that our controller is setup, we can open the template HTML and add the package's city and country to the DOM. We'll also add a ng-style to the parent section element to set the background-image to the package's image. When using ng-style the syntax follows: { 'css-property': 'css-value' }. You can use {{}} to insert $scope.values into ng-style.

<section class="booked-main-container" ng-style="{ 'background-image': 'url({{ package.image }})' }">
  <h1>Thanks for trusting us with your trip to <br>  {{ package.city }}, {{ package.country }}</h1>

  <!--This button needs a ui-sref that points to packages -->
  <button ui-sref="packages"> VIEW MORE PACKAGES </button>
</section>

We'll also want to add an ng-if to the section element. This way, the element wont be rendered until $scope.package exists. Otherwise, our ng-style won't work correctly. To add an ng-if we add it to an element as an attribute and assign it an expression. We can do a simple truthy check for $scope.package.

<section ng-if="package" class="booked-main-container" ng-style="{ 'background-image': 'url({{ package.image }})' }">
  <h1>Thanks for trusting us with your trip to <br>  {{ package.city }}, {{ package.country }}</h1>

  <!--This button needs a ui-sref that points to packages -->
  <button ui-sref="packages"> VIEW MORE PACKAGES </button>
</section>

Finally, we'll need to update the ui-sref to link to the correct packages route. If we look in app/app.js, in our router configuration, we'll see that the packages route is expecting a country parameter. To add parameters in a ui-sref all we need to do is add ({ paramName: paramValue }) next to the route name. If we take a look at our data in mainSrvc we can see that our package objects have a property called country. Therefore, we can use {{ package.country }} in the DOM to fix our ui-sref link.

<section ng-if="package" class="booked-main-container" ng-style="{ 'background-image': 'url({{ package.image }})' }">
  <h1>Thanks for trusting us with your trip to <br>  {{ package.city }}, {{ package.country }}</h1>

  <!--This button needs a ui-sref that points to packages -->
  <button ui-sref="packages({ country: '{{ package.country }}' })"> VIEW MORE PACKAGES </button>
</section>

Solution

app/booked/bookedTmpl.html 
<section ng-if="package" class="booked-main-container" ng-style="{ 'background-image': 'url({{ package.image }})' }">
  <h1>Thanks for trusting us with your trip to <br>  {{ package.city }}, {{ package.country }}</h1>

  <!--This button needs a ui-sref that points to packages -->
  <button ui-sref="packages({ country: '{{ package.country }}' })"> VIEW MORE PACKAGES </button>
</section>
app/booked/bookedCtrl.js 
angular.module('devmtnTravel').controller('bookedCtrl', function( $scope, $stateParams, mainSrvc ) {
  mainSrvc.getPackageInfo().then( function( response ) {
    $scope.allPackages = response.data;

    if ( $stateParams.id ) {
      $scope.packageIndex = $scope.allPackages.findIndex( function( package ) {
        return package.id === parseInt( $stateParams.id );
      }); 
  
      if ( $scope.packageIndex !== -1 ) {
        $scope.package = $scope.allPackages[ $scope.packageIndex ];
      }
    }
  });
});

Step 8

Summary

In this step, we'll complete the locations feature. The locations feature is designed to show all the available packages by country.

Instructions

  • Open app/locations/locationsTmpl.html and app/locations/locationsCtrl.js.
  • Inside of locationsCtrl.js:
    • Inject mainSrvc into the controller.
    • Call the getTravelInfo method and catch the response:
      • Assign a new $scope variable called locations that equals the response's data.
  • Inside of locationsTmpl.html:
    • Add a ng-repeat through locations on the section element with the class of location-card.
      • Update the img element's ng-src to be the location's image.
      • Update the img element's alt to be the location's country.
      • Update the h1 element's value to be the location's country.
      • Update the p element's value to be the location's desc.
    • Fix the ui-sref to include a country parameter that equals the location's country.
Detailed Instructions

Let's begin opening app/locations/locationsCtrl.js and get the data we need from mainSrvc. To do this we'll need to inject mainSrvc and then call its getTravelInfo method. We can then catch its response and assign its data to a new $scope variable called locations.

angular.module('devmtnTravel').controller('locationsCtrl', function( $scope, mainSrvc ) {
  mainSrvc.getTravelInfo().then( function( response ) {
    $scope.locations = response.data;
  });
});

Now that our controller is setup, we can repeat through locations on the DOM. We'll want to update the ng-src to be the location's image and the alt to be the location's country on the img element. We'll also want to update the h1 element to have a value of the location's country and update the p element to have a value of the location's desc.

<section class="locations-container">
  <section class="location-card" ng-repeat="location in locations">
    <div class="image-container">
      <img ng-src="{{ location.image }}" alt="{{ location.country }}" />
    </div>

    <div class="location-inner-left">
      <h1>{{ location.country }}</h1>
      <p>{{ location.desc }}</p>
    </div>

    <div class="location-inner-right">
      <h3>Package Start At ${{ location.price }}</h3>
      
      <!--This button needs a ui-sref that points to packages-->
      <button ui-sref="packages">See country packages</button>
    </div>
  </section>
</section>

Lastly, we'll need to fix the ui-sref so that it properly calls the packages route with the location's country.

<!--This button needs a ui-sref that points to packages-->
<button ui-sref="packages({ country: '{{ location.country }}' })">See country packages</button>

Solution

app/locations/locationsCtrl.js 
angular.module('devmtnTravel').controller('locationsCtrl', function( $scope, mainSrvc ) {
  mainSrvc.getTravelInfo().then( function( response ) {
    $scope.locations = response.data;
  });
});
app/locations/locationsTmpl.html 
<section class="locations-container">
  <section class="location-card" ng-repeat="location in locations">
    <div class="image-container">
      <img ng-src="{{ location.image }}" alt="{{ location.country }}" />
    </div>

    <div class="location-inner-left">
      <h1>{{ location.country }}</h1>
      <p>{{ location.desc }}</p>
    </div>

    <div class="location-inner-right">
      <h3>Package Start At ${{ location.price }}</h3>
      
      <!--This button needs a ui-sref that points to packages-->
      <button ui-sref="packages({ country: '{{ location.country }}' })">See country packages</button>
    </div>
  </section>
</section>

Step 9

Summary

In this step, we'll complete the packages feature. The packages feature is designed to show all available packages by country.

Instructions

  • Open app/packages/packagesTmpl.html and app/packages/packagesCtrl.js.
  • Inside of packagesCtrl.js:
    • Inject $stateParams into the controller.
    • Inject mainSrvc into the controller.
    • Call the getPackageInfo method and catch the response:
      • Assign a new $scope variable called allPackages that equals the response's data.
      • Filter out the packages that equal the country specified in the URL into a new $scope variable called packages.
  • Inside of packagesTmpl.html:
    • Add a ng-repeat through packages on the section element with the class name of package-card.
      • Update the img element's ng-src to be the package's image.
      • Update the img element's alt to be the package's country.
      • Update the h6 element's value to be the package's city.
      • Update the h1 element's value to be the package's country.
      • Update the p element's value to be the package's desc.
      • Update the h3 element's value to be the package's price.
    • Fix the ui-sref to include an id parameter that equals the package's id.
Detailed Instructions

Let's begin by opening app/packages/packagesCtrl.js. We'll need access to the package ID in the URL and access to the getPackageInfo method on mainSrvc.js. So let's inject $stateParams and mainSrvc into the controller.

angular.module('devmtnTravel').controller('packagesCtrl', function( $scope, $stateParams, mainSrvc ) {

});

Now that we have access to these things, we can call then getPackageInfo and catch its response. Inside our catch, we can assign a new $scope variable called allPackages that equals the response's data. We'll also need another $scope variable called package. We can determine the value of package by filtering $scope.allPackages by country. Remember that this page is loaded with a URL parameter called country.

angular.module('devmtnTravel').controller('packagesCtrl', function( $scope, $stateParams, mainSrvc ) {
  mainSrvc.getPackageInfo().then( function( response ) {
    $scope.allPackages = response.data;

    if ( $stateParams.country ) {
      $scope.packages = $scope.allPackages.filter( function( package ) {
        return package.country === $stateParams.country;
      });
    }
  });
});

We can then use $scope.packages with an ng-repeat to show all the packages on the DOM. Let's open app/packages/packagesTmpl.html and locate the section element with the class of package-card. Let's add an ng-repeat through packages on this element. We will also the following elements inside of package-card:

  • img element's ng-src to be the package's image.
  • img element's alt to be the package's country.
  • h6 element's value to be the package's city.
  • h1 element's value to be the package's country.
  • p element's value to be the package's desc.
  • h3 element's value to be the package's price.
<section class="packages-main">
  <section class="package-card" ng-repeat="package in packages">
    <img ng-src="{{ package.image }}" alt="{{ package.country }}" />

    <h6>{{ package.city }}</h6>
    <h1>{{ package.country }}</h1>
    <p>{{ package.desc }}</p>
    <h3>${{ package.price }}</h3>

    <!--This button needs a ui-sref that points to booked-->
    <button ui-sref="booked">Book Now</button>
  </section>
</section>

Lastly, we'll need to update the value of the ui-sref to include the package's id as a route parameter.

<!--This button needs a ui-sref that points to booked-->
<button ui-sref="booked({ id: '{{ package.id }}' })">Book Now</button>

Solution

app/packages/packagesCtrl.js 
angular.module('devmtnTravel').controller('packagesCtrl', function( $scope, $stateParams, mainSrvc ) {
  mainSrvc.getPackageInfo().then( function( response ) {
    $scope.allPackages = response.data;

    if ( $stateParams.country ) {
      $scope.packages = $scope.allPackages.filter( function( package ) {
        return package.country === $stateParams.country;
      });
    }
  });
});
app/packages/packagesTmpl.html 
<section class="packages-main">
  <section class="package-card" ng-repeat="package in packages">
    <img ng-src="{{ package.image }}" alt="{{ package.country }}" />

    <h6>{{ package.city }}</h6>
    <h1>{{ package.country }}</h1>
    <p>{{ package.desc }}</p>
    <h3>${{ package.price }}</h3>

    <!--This button needs a ui-sref that points to booked-->
    <button ui-sref="booked({ id: '{{ package.id }}' })">Book Now</button>
  </section>
