Why Build a Movie Genre Website with ReactJS and GitHub Copilot?

“GitHub Copilot is like having a senior developer by your side, suggesting code in real-time to cut development time dramatically.” – Frontend Developer

This project is perfect for:

• Practicing ReactJS with modern tools like Vite and TypeScript.

• Learning to fetch and display dynamic data using APIs.

• Experiencing GitHub Copilot’s ability to autogenerate components, hooks, and error-handling logic.

• Building a portfolio-worthy app with responsive design and smooth UX.

With Copilot, you’ll write cleaner code, faster, while focusing on core logic rather than boilerplate. Let’s dive into the step-by-step process!

Step 1: Set Up Your React Project with Vite

To start, you’ll create a React project using Vite, a lightning-fast build tool, and let GitHub Copilot suggest an optimized folder structure.

Initialize the Project

Run the following command to scaffold a React project with TypeScript (or JavaScript if preferred):

npm create vite@latest movie-genre-app -- --template react-ts
cd movie-genre-app
npm install
npm run dev

• Why Vite? It’s faster than Create React App and supports TypeScript out of the box.

• Copilot’s Role: As you type npm create, Copilot may suggest the full command or even propose installing dependencies like axios or Tailwind CSS.

Create Folder Structure

Organize your project with a clean structure:

/src
  /components
    GenreList.jsx
    MovieList.jsx
    MovieCard.jsx
  /pages
    Home.jsx
  /services
    api.js
  App.jsx

• Copilot Tip: In VS Code, type Create a React component folder structure, and Copilot will suggest creating these folders and files with boilerplate code, like:

// src/components/GenreList.jsx
import React from 'react';

const GenreList = () => {
  return <div>Genre List</div>;
};

export default GenreList;

Strong Emphasis: Use Vite for fast development and let Copilot generate boilerplate files to save time.

Step 2: Build the Genre Filtering Interface

Your app will display a list of movie genres (e.g., Action, Comedy) and filter movies based on the selected genre.

Display Genres

Create a GenreList component to fetch and render genres. Use React Hooks for state management:

// src/components/GenreList.jsx
import { useState, useEffect } from 'react';
import { getGenres } from '../services/api';

const GenreList = ({ onGenreSelect }) => {
  const [genres, setGenres] = useState([]);
  
  useEffect(() => {
    const fetchGenres = async () => {
      try {
        const response = await getGenres();
        setGenres(response.data.genres);
      } catch (error) {
        console.error('Error fetching genres:', error);
      }
    };
    fetchGenres();
  }, []);

  return (
    <div className="flex gap-4">
      {genres.map((genre) => (
        <button
          key={genre.id}
          onClick={() => onGenreSelect(genre.id)}
          className="px-4 py-2 bg-blue-500 text-white rounded hover:bg-blue-600"
        >
          {genre.name}
        </button>
      ))}
    </div>
  );
};

export default GenreList;

• Copilot’s Magic: Type Create a genre list component, and Copilot will suggest the useState, useEffect, and map logic, including Tailwind CSS classes for styling.

• Strong Emphasis: Use Tailwind CSS for rapid, responsive styling.

Handle Genre Selection

Pass the selected genre ID to the MovieList component via a prop:

// src/App.jsx
import { useState } from 'react';
import GenreList from './components/GenreList';
import MovieList from './components/MovieList';

const App = () => {
  const [selectedGenre, setSelectedGenre] = useState(null);

  return (
    <div className="container mx-auto p-4">
      <h1 className="text-3xl font-bold mb-4">Movie Genre App</h1>
      <GenreList onGenreSelect={setSelectedGenre} />
      <MovieList genreId={selectedGenre} />
    </div>
  );
};

export default App;

• Copilot Tip: Copilot will autocomplete the useState hook and suggest passing props like onGenreSelect.

Step 3: Integrate the TMDb API

You’ll use The Movie Database (TMDb) API to fetch genres and movies. Sign up at themoviedb.org to get an API key.

Set Up API Calls

Install axios for HTTP requests:

npm install axios

Create an api.js file in the services folder:

// src/services/api.js
import axios from 'axios';

const API_KEY = 'your-tmdb-api-key';
const BASE_URL = 'https://api.themoviedb.org/3';

export const getGenres = async () => {
  return await axios.get(`${BASE_URL}/genre/movie/list?api_key=${API_KEY}`);
};

export const getMoviesByGenre = async (genreId) => {
  return await axios.get(
    `${BASE_URL}/discover/movie?api_key=${API_KEY}&with_genres=${genreId}`
  );
};

• Copilot’s Role: Type Create an axios function to fetch TMDb genres, and Copilot will generate the async/await structure and error handling.

• Strong Emphasis: Replace your-tmdb-api-key with your actual API key.

Handle Loading and Errors

Add a Loading component and error state in MovieList:

// src/components/MovieList.jsx
import { useState, useEffect } from 'react';
import { getMoviesByGenre } from '../services/api';
import MovieCard from './MovieCard';

const MovieList = ({ genreId }) => {
  const [movies, setMovies] = useState([]);
  const [loading, setLoading] = useState(false);
  const [error, setError] = useState(null);

  useEffect(() => {
    if (!genreId) return;
    const fetchMovies = async () => {
      setLoading(true);
      try {
        const response = await getMoviesByGenre(genreId);
        setMovies(response.data.results);
        setLoading(false);
      } catch (error) {
        setError('Failed to load movies');
        setLoading(false);
      }
    };
    fetchMovies();
  }, [genreId]);

  if (loading) return <div className="text-center">Loading...</div>;
  if (error) return <div className="text-red-500">{error}</div>;

  return (
    <div className="grid grid-cols-1 sm:grid-cols-2 md:grid-cols-3 gap-4 mt-4">
      {movies.map((movie) => (
        <MovieCard key={movie.id} movie={movie} />
      ))}
    </div>
  );
};

export default MovieList;

• Copilot Tip: Copilot suggests the loading and error states, plus the grid layout with Tailwind.

Step 4: Display Movies with MovieCard

Create a MovieCard component to render each movie’s poster, title, and overview.

// src/components/MovieCard.jsx
const MovieCard = ({ movie }) => {
  const imageUrl = `https://image.tmdb.org/t/p/w500${movie.poster_path}`;

  return (
    <div className="border rounded-lg overflow-hidden shadow-lg hover:shadow-xl transition">
      <img src={imageUrl} alt={movie.title} className="w-full h-64 object-cover" />
      <div className="p-4">
        <h3 className="text-lg font-semibold">{movie.title}</h3>
        <p className="text-sm text-gray-600">{movie.overview.slice(0, 100)}...</p>
      </div>
    </div>
  );
};

export default MovieCard;

• Copilot’s Help: Type Create a movie card component, and Copilot will suggest the JSX structure, Tailwind classes, and image URL formatting.

• Strong Emphasis: Use Tailwind for responsive card layouts.

Step 5: Optimize UX and Refactor Code

Polish your app for a professional look and maintainable codebase.

Refactor Components

• Split Logic: Keep GenreList, MovieList, and MovieCard focused on single responsibilities.

• Custom Hook: Create a custom hook for API calls if needed:

// src/hooks/useMovies.js
import { useState, useEffect } from 'react';
import { getMoviesByGenre } from '../services/api';

export const useMovies = (genreId) => {
  const [movies, setMovies] = useState([]);
  const [loading, setLoading] = useState(false);
  const [error, setError] = useState(null);

  useEffect(() => {
    if (!genreId) return;
    const fetchMovies = async () => {
      setLoading(true);
      try {
        const response = await getMoviesByGenre(genreId);
        setMovies(response.data.results);
        setLoading(false);
      } catch (error) {
        setError('Failed to load movies');
        setLoading(false);
      }
    };
    fetchMovies();
  }, [genreId]);

  return { movies, loading, error };
};

• Copilot Tip: Type Create a custom hook for movie fetching, and Copilot will generate this hook.

Add UX Enhancements

• Hover Effects: Add Tailwind’s hover: classes to MovieCard for interactivity.

• Loading Animation: Replace the plain “Loading…” text with a spinner:

<div className="text-center">
  <div className="animate-spin rounded-full h-8 w-8 border-t-2 border-blue-500 mx-auto"></div>
</div>

• Strong Emphasis: Small UX improvements like animations boost user engagement.
