Step 1: setting up the environment

1. clone branch: https://github.com/manekinekko/angular2-codelab/tree/step-1
2. create and add a root component

• name it Ng2CodelabApp
• store it in src/app/ng2-codelab.ts
• use selector <app></app>
• create the template src/app/ng2codelab.html
  • use template HTML from home.html#L17-L80

3. bootstrap your application in src/app.ts

Step 2: home and theme-card components

1. clone branch: https://github.com/manekinekko/angular2-codelab/tree/step-2
2. create and add a dump component

• name it ThemeCard
• store it in src/app/components/theme-card/theme-card.ts
• use selector <theme-card></theme-card>
• use template src/app/components/theme-card/theme-card.html
  • use template HTML from home.html#L45-L59

3. update the smart component Home

• you can find this component in src/app/components/home/home.ts
• use template src/app/components/home/home.html
  • Hint: use the dump <theme-card></theme-card>
• use the provided service src/app/services/technologies-store/technologies-store.ts

Step 3: setting up the router and question component

1. clone branch: https://github.com/manekinekko/angular2-codelab/tree/step-3
2. create and add a dump component

• name it QuestionCard
• store it in src/app/components/question-card/question-card.ts
• use selector <question-card></question-card>
• use template src/app/components/question-card/question-card.html
  • use template HTML from quizz.html#L34-L71

3. add a route configurtion to the root component Ng2CodelabApp

• add two routes: Home and QuestionCard

4. update the ThemeCard and it template to use the router
5. update the Ng2CodelabApp template with the router directive
6. check the necessary router providers included in src/app.ts

• we injected for you the router dependencies in app.tsL5-L6

Step 4: technology component

In this step, you are provided with all the necessary files containing the heavy work so you can focus on the basics. You can still take a momment and read this commit diff to understand what's really happening https://github.com/manekinekko/angular2-codelab/commit/39b9f0e6748825b51456d18dcd1cdd8d280fec7f

1. clone branch: https://github.com/manekinekko/angular2-codelab/tree/step-4
2. update the QuestionCard component and its template so it can display and navigate the questions correctly

• use @Input() and @Output() in order to receive a question (which will be the current question) property and send an checked event.
• use the elvis operator to allow parsing undefined values, ie: {{question?.title}}

3. if you like challenges, you can re-implement these files:

• src/app/components/technology/technology.ts
• src/app/services/question-store/question-store.ts
• src/app/services/session-store/session-store.ts

Step 5: summary component

1. clone branch: https://github.com/manekinekko/angular2-codelab/tree/step-5
2. create and add a smart component

• name it Summary
• store it in src/app/components/summary/summary.ts
• use an inline template
  • use template HTML from summary.html#L50-L138
  • Hint: reuse the <question-card></question-card> component

3. use a factory provider to get a new instance of the QuestionsStore

• read the stored session using SessionStore.read()

4. use the QuestionCard component to display the saved answers
5. update the router configuration in src/app/ng2-codelab.ts
6. check solution: https://github.com/manekinekko/angular2-codelab/tree/step-5-solution
7. diff: https://github.com/manekinekko/angular2-codelab/compare/step-5...step-5-solution

Step 6: add a Pipe

1. clone branch: https://github.com/manekinekko/angular2-codelab/tree/step-6
2. add an input property (boolean) to the QuestionCard to enable/disable a "preview mode"

• name it preview
• in preview mode, the checkboxes must be disabled
• in preview mode, the status of a choice is shown (see pipe below)

3. add a pipe that shows a ✔ or ✘ if the given choice is correct or wrong, in the QuestionCard component

• name the class MarkPipe
• name the pipe mark
• store it in src/app/pipes/mark-pipe/mark-pipe.ts

5. diff: https://github.com/manekinekko/angular2-codelab/compare/step-6...step-6-solution

Step 7: add a directive

1. clone branch: https://github.com/manekinekko/angular2-codelab/tree/step-7
2. update the content of the directive StatusDirective that sets the color of a choice

• use selector [status]
• use the existing <span></span> in question-card.html#L27
• if the choice is correct, set the color to green, otherwise set it to red
  • use an @Input() property to get a choice status (choice.isCorrect())
• use the Renderer to set the style this.renderer.setElementStyle(nativeElement, styleProperty, value)
• the directive is stored in src/app/directives/status-directive/status-directive.ts
