Angular Signals - Building Quiz Angular Project

Learn to create isolated Angular components, structure a component tree from the root component to header and content, and build a quiz feature with standalone components: quiz, question, and answer.

Render Angular components markup for a quiz app, displaying a score, current question, and next button, with quiz question and answer components and four options.

Define a question interface and build a quiz service in Angular to share business logic across components, using a root singleton and mock questions for testing.

Learn how Angular signals replace local variables with writeable signals, computed and effect, reading values with brackets and using set to update reactive quiz components.

Manage a questions array and a current question index with signals, render the current question title, and simplify access via a computed current question.

Implement a next button that moves to the next question by updating the current question index via the quiz service, triggering user interface re-render.

Implement a quiz results page by computing show results when the current index reaches the last question, render the results markup, and provide a restart action to reset signals.

Render quiz answers in an Angular app using signals and input signals; compose a current question answers array with letters A, B, C, and D and shuffle it.

Implement interactive quiz behavior with Angular signals by tracking the current answer and correct answers count, highlighting correct and wrong choices, and resetting on the next question.

Wrap the next button in an if condition that checks the quiz service's current answer, a string or null, so the button appears only after an answer is selected.

Fetch quiz questions from a trivia API via an angular service, use http client with RxJS to decode uri components and normalize backend data to client format and populate quiz.

Learn to handle API errors by capturing HTTP failure responses, updating an error signal in the quiz service, and rendering a user-friendly server error message when questions fail to load.

Rent a production server to deploy your project with full control, bypassing free-tier limits, and set up a cheap Hetzner Ubuntu server with IPv4/IPv6 and secure root access.

Install nginx and update packages on the production server. Create an nginx conf for angular-quiz.com, serve static files from /var/angular-quiz.com/html, restart nginx, and verify with the IP.

Deploy a production Angular app by building with npm run build, copy dist/browser files to the server via SCP, configure hosts for testing, and verify nginx serves the static assets.

Congratulations on finishing the Angular quiz course. Emphasize building your own projects, solving problems independently, and exploring ideas like a to-do list or a Twitter clone to deepen Angular skills.
