Code Explanation

LyricsFinder Component

The LyricsFinder component handles the API integration and manages the search results.

import { useState } from "react";
import SearchForm from "./SearchForm";

const LyricsFinder = () => {
  const [lyrics, setLyrics] = useState("");
  const [loading, setLoading] = useState(false);
  const [error, setError] = useState("");

  const fetchLyrics = async (song, artist) => {
    setLoading(true);
    setError("");
    try {
      const response = await fetch(`https://api.lyrics.ovh/v1/${artist}/${song}`);
      if (!response.ok) {
        throw new Error("Lyrics not found");
      }
      const data = await response.json();
      setLyrics(data.lyrics);
    } catch (err) {
      setError(err.message);
    } finally {
      setLoading(false);
    }
  };

  return (
    <div className="lyrics-finder">
      <SearchForm onSearch={fetchLyrics} />
      {loading && <p>Loading...</p>}
      {error && <p className="error">{error}</p>}
      {lyrics && <pre className="lyrics">{lyrics}

}

); }; export default LyricsFinder;

This component manages the state for lyrics, loading, and error messages. It fetches lyrics from the API and displays them.

SearchForm Component

The SearchForm component provides a form for users to input the song title and artist name.

This component takes user input for the song title and artist and triggers the search function.

App Component

This component provides a header and renders the LyricsFinder component in the center.

CSS Styling

The styling ensures a clean layout with user-friendly visuals and responsive design.

Installation and Usage

To get started with this project, clone the repository and install the dependencies:

This will start the development server, and the application will be running at http://localhost:3000.

Live Demo

Conclusion

The Lyrics Finder project is an excellent way to practice integrating APIs and handling dynamic content in React. It provides a practical example of building a useful application with a clean and interactive user interface.
