Conclusion of the Project

Learning Outcome

Building the Quote Generator app has given us practical experience with several key web development concepts. Here are the main learning outcomes from this project:

• Setting up a React Project: You learned how to initialize a React app using Create React App and understood the default project structure. This included running the development server and observing the hot-reloading as you make changes.
• JSX and Component Structure: We built a functional React component (App) using JSX to describe the UI. You now know how to structure a component’s return statement with HTML-like syntax and embed dynamic values using curly braces.
• State Management with Hooks: Using the useState hook, we managed component state (for quote and author). You saw firsthand how updating state causes React to re-render the UI with new data, enabling dynamic content.
• Side Effects with Hooks: Using the useEffect hook, we performed side effects (data fetching). We utilized the dependency array to control when the effect runs (once on mount for initial data load). This is a common pattern for fetching data in functional components.
• Fetching Data from an API: We integrated the Quote Generator with a real API (Quotable). You practiced using the Fetch API (with async/await) to send an HTTP request and handle the JSON response. This is hugely important – most real-world apps communicate with servers or APIs. You also gracefully handled errors with try/catch.
• Event Handling in React: We added an event handler to a button (onClick) to trigger state updates (fetching a new quote). You learned how to define a function and attach it to a UI element’s event, a fundamental for interactivity.
• Build and Deployment Process: You followed the steps to prepare a production build (npm run build) and learned how to deploy to Netlify. This included pushing code to GitHub and using Netlify’s GitHub integration. Now you have exposure to the idea of continuous deployment – where each code change can automatically deploy to a live site.

Overall, you’ve gone through the entire lifecycle of a web app: concept → coding → styling → testing locally → deploying publicly. This holistic experience is invaluable. You can now confidently create a simple React app that interacts with an API, and you know how to put it on the web for others to see.

In the screenshot above, you can see the app’s basic UI. Each time you press the “New Quote” button, the displayed quote (and its author) will change to a new random one fetched from the Dummy JSON API.

MCQs

Test your understanding of React basics, Hooks, API usage, and deployment with these multiple-choice questions:

1. What is ReactJS primarily used for?
   A. Building the back-end of web applications.
   B. Creating styles for websites.
   C. Building interactive user interfaces on the front-end.
   D. Managing databases for web apps.
   Correct answer: C. React is a JavaScript library for building dynamic front-end user interfaces.
2. Which Hook would you use to add state to a functional component in React?
   A. useEffect
   B. useState
   C. useRouter
   D. useCSS
   Correct answer: B. useState is the Hook that lets functional components have state variables.
3. When should the effect inside a useEffect(() => {...}, [ ]) run?
   A. On every re-render of the component.
   B. Only once, when the component mounts (initial render)
   C. Whenever a state variable updates, regardless of dependencies.
   D. Only when the component unmounts.
   Correct answer: B. An empty dependency array means the effect runs once on mount.
4. In our Quote Generator app, what does the Fetch API do?
   A. It directly updates the DOM with new content.
   B. It requests a random quote from the Quotable API and returns a promise with the response.
   C. It styles the application using CSS fetched from a server.
   D. It compiles the React code into browser-ready JavaScript.
   Correct answer: B. The Fetch API is used to make HTTP requests – in our case, to get quote data.
5. Which of the following is a required step to deploy a React app to Netlify via GitHub?
   A. Converting the React app into a WordPress plugin.
   B. Running npm start on Netlify servers.
   C. Connecting your GitHub repository to Netlify and specifying the build command and publish directory.
   D. Manually copying your src files to a Netlify FTP server.
   Correct answer: C. You need to link Netlify to your GitHub repo so it can build and deploy the app. Netlify will run the production build (e.g., npm run build) and host the generated files.
