Building an NSFW AI Image Generator with Next.js, React, and Tailwind CSS

In this article, we'll walk through how we built an NSFW AI Image Generator using Next.js, React, and Tailwind CSS. We'll explore the technologies involved, discuss the implementation details, and share some code samples to help you get started on a similar project. Note: When working with NSFW content, always ensure that your project complies with all legal and ethical guidelines.

Introduction

Generating images from text prompts has become increasingly popular with advancements in AI. We wanted to create a web application that allows users to generate NSFW (Not Safe For Work) images using AI models, with a focus on performance and scalability. By leveraging Next.js for server-side rendering, React for building UI components, and Tailwind CSS for styling, we built a responsive and efficient application that can scale to meet user demand.

Technologies Used

Before diving into the implementation, let's take a look at the key technologies we used:

• Next.js: A React framework that enables server-side rendering and static site generation.
• React: A JavaScript library for building user interfaces.
• Tailwind CSS: A utility-first CSS framework for rapidly building custom designs.
• Sentry: An application monitoring platform for error tracking.
• OAuth Integration: For user authentication via platforms like Google.
• Axios: For making HTTP requests to the AI image generation API.

Project Setup

1. Initialize the Next.js Application

First, create a new Next.js project:

npx create-next-app nsfw-image-generator
cd nsfw-image-generator

2. Install Dependencies

Install the required dependencies, including Tailwind CSS, Sentry, Axios, and OAuth-related packages:

# Install Tailwind CSS and its peer dependencies
npm install tailwindcss postcss autoprefixer
npx tailwindcss init -p

# Install Sentry for error tracking
npm install @sentry/nextjs

# Install other dependencies
npm install axios react-google-login

3. Configure Tailwind CSS

In your tailwind.config.js, set up the paths to all of your template files:

module.exports = {
  content: [
    './pages/**/*.{js,ts,jsx,tsx}',
    './components/**/*.{js,ts,jsx,tsx}',
  ],
  // ... other configurations
}

Create a globals.css file in the styles directory and include the Tailwind directives:

@tailwind base;
@tailwind components;
@tailwind utilities;

Building the NSFW Image Generator

1. Implementing the AI Backend

For the AI image generation, you can use an external API that supports generating images from text prompts, including NSFW content (ensure you comply with all legal and ethical guidelines).

Here's an example using Axios to call the API:

// lib/api.js
import axios from 'axios';

export const generateImage = async (prompt) => {
  // Replace with the actual URL and parameters required by your AI API
  const response = await axios.post('https://api.example.com/generate', { prompt });
  return response.data;
};

Next, create a serverless function in Next.js to act as a proxy for the API call:

// pages/api/generate-image.js
import { generateImage } from '../../lib/api';

export default async function handler(req, res) {
  if (req.method !== 'POST') {
    return res.status(405).json({ error: 'Method not allowed' });
  }

  const { prompt } = req.body;
  try {
    const { imageUrl } = await generateImage(prompt);
    res.status(200).json({ imageUrl });
  } catch (error) {
    // Log the error to Sentry if configured
    console.error('Error generating image:', error);
    res.status(500).json({ error: 'Error generating image' });
  }
}

2. Creating the Frontend Components

a. The Input Form

Create a component that allows users to input a text prompt:

// components/PromptForm.js
import { useState } from 'react';

export default function PromptForm({ onSubmit }) {
  const [prompt, setPrompt] = useState('');

  const handleSubmit = (e) => {
    e.preventDefault();
    if (!prompt.trim()) return;
    onSubmit(prompt);
  };

  return (
    <form onSubmit={handleSubmit} className="flex flex-col items-center w-full max-w-md mx-auto p-4">
      <input
        type="text"
        value={prompt}
        onChange={(e) => setPrompt(e.target.value)}
        placeholder="Enter your prompt..."
        className="w-full p-2 border border-gray-300 rounded mb-4"
      />
      <button type="submit" className="bg-blue-500 hover:bg-blue-600 text-white p-2 rounded w-full">
        Generate Image
      button>
    form>
  );
}

b. Displaying the Generated Image

Create a component to display the generated image:

// components/ImageDisplay.js
export default function ImageDisplay({ imageUrl }) {
  if (!imageUrl) return null;
  return (
    <div className="flex justify-center mt-6">
      <img src={imageUrl} alt="Generated NSFW Content" className="max-w-full rounded shadow-lg" />
    div>
  );
}

c. Integrating Everything in the Main Page

Now, integrate the prompt form and image display in your main page:

// pages/index.js
import { useState } from 'react';
import PromptForm from '../components/PromptForm';
import ImageDisplay from '../components/ImageDisplay';
import axios from 'axios';

export default function Home() {
  const [imageUrl, setImageUrl] = useState('');
  const [loading, setLoading] = useState(false);

  const handleGenerateImage = async (prompt) => {
    setLoading(true);
    try {
      const response = await axios.post('/api/generate-image', { prompt });
      setImageUrl(response.data.imageUrl);
    } catch (error) {
      console.error('Error generating image:', error);
    } finally {
      setLoading(false);
    }
  };

  return (
    <div className="min-h-screen bg-gray-100 py-10">
      <h1 className="text-4xl font-bold text-center mb-8">NSFW AI Image Generatorh1>
      <PromptForm onSubmit={handleGenerateImage} />
      {loading ? (
        <div className="flex justify-center mt-6">
          <p>Generating image...p>
        div>
      ) : (
        <ImageDisplay imageUrl={imageUrl} />
      )}
    div>
  );
}

3. Integrating OAuth for User Authentication

To allow user authentication, integrate OAuth using the react-google-login package. This will enable users to log in with their Google account before using the generator.

// components/Login.js
import React from 'react';
import { GoogleLogin } from 'react-google-login';

export default function Login({ onLogin }) {
  const responseGoogle = (response) => {
    console.log('Google login response:', response);
    // Send token to your backend for further verification if necessary
    onLogin(response);
  };

  return (
    <div className="flex justify-center my-6">
      <GoogleLogin
        clientId="YOUR_GOOGLE_CLIENT_ID"
        buttonText="Login with Google"
        onSuccess={responseGoogle}
        onFailure={responseGoogle}
        cookiePolicy={'single_host_origin'}
      />
    div>
  );
}

Then, include the Login component in your main page or a dedicated authentication page as needed.

4. Error Monitoring with Sentry

Integrate Sentry to track errors and performance issues. Create Sentry configuration files for both client and server:

// sentry.client.config.js
import * as Sentry from '@sentry/nextjs';

Sentry.init({
  dsn: 'YOUR_SENTRY_DSN',
  tracesSampleRate: 1.0,
});

// sentry.server.config.js
import * as Sentry from '@sentry/nextjs';

Sentry.init({
  dsn: 'YOUR_SENTRY_DSN',
  tracesSampleRate: 1.0,
});

Ensure these files are imported early in your application lifecycle as per the Sentry for Next.js documentation.

Deployment

Once your application is complete and thoroughly tested, you can deploy it using platforms like Vercel or Netlify. Both platforms offer seamless integration with Next.js applications. Before deployment, make sure to:

• Set environment variables (e.g., API keys, Sentry DSN, OAuth credentials) securely.
• Review your API rate limits and scaling options with your AI image generation service.
• Test your deployment in a staging environment.
