AI Content Optimization App

Create a full `App.js` file for an AI-Powered Content Optimization SaaS application using React.js. This application will import the Google Generative AI module, initialize it with a provided API key, and utilize a generative model for content optimization. Additionally, create a separate CSS file to style the application. Make sure to include structure for a user interface that allows users to input content, trigger the generative model, and display optimized content. Below are the specifications and steps to achieve this: ## Specifications: - Use React.js as the primary framework. - Import `GoogleGenerativeAI` from `@google/generative-ai`. - Initialize `GoogleGenerativeAI` with a mock or placeholder API key. - Implement functional components for user input and displaying results. - Write a CSS stylesheet for basic styling of the UI elements. ## Steps: 1. Import React and necessary modules at the beginning of the `App.js` file. 2. Create a functional component called `App` that includes: - State variables for user input and generated content. - A text area for users to enter content. - A button to trigger the generative model. - A section to display the optimized content. 3. Use the generative model to process user input when the button is clicked. 4. Add error handling for API interactions. 5. In a separate `App.css` file, style the application with basic layouts, colors, and alignment. ## Output Format: The final output should consist of two files: 1. `App.js`: Contains all the React component code. 2. `App.css`: Contains the styling for the application. ## Example of `App.js`: ```javascript import React, { useState } from 'react'; import { GoogleGenerativeAI } from "@google/generative-ai"; import './App.css'; const genAI = new GoogleGenerativeAI("GEMINI_API_KEY"); const model = genAI.getGenerativeModel({ model: "gemini-1.5-flash" }); const App = () => { const [inputText, setInputText] = useState(""); const [optimizedContent, setOptimizedContent] = useState(""); const handleInputChange = (event) => { setInputText(event.target.value); }; const handleGenerate = async () => { try { const response = await model.generate({ input: inputText }); setOptimizedContent(response.output); } catch (error) { console.error('Error generating content:', error); alert('Failed to generate content. Please try again.'); } }; return ( <div className="app-container"> <h1>AI-Powered Content Optimization</h1> <textarea value={inputText} onChange={handleInputChange} placeholder="Enter your content here..." /> <button onClick={handleGenerate}>Optimize Content</button> <h2>Optimized Content:</h2> <div className="output-container"> <p>{optimizedContent}</p> </div> </div> ); }; export default App; ``` ## Example of `App.css`: ```css .app-container { max-width: 600px; margin: auto; padding: 20px; font-family: Arial, sans-serif; } textarea { width: 100%; height: 100px; margin-bottom: 10px; padding: 10px; border: 1px solid #ccc; border-radius: 4px; } button { padding: 10px 15px; background-color: #007bff; color: white; border: none; border-radius: 5px; cursor: pointer; } .output-container { margin-top: 20px; padding: 10px; border: 1px solid #ddd; border-radius: 5px; } ```
