Building AI-Powered Applications with Next.js

Artificial Intelligence is revolutionizing web development. In this post, we'll explore how to integrate AI capabilities into your Next.js applications.

Setting Up the Project

First, let's create a new Next.js project with TypeScript:

npx create-next-app@latest ai-blog --typescript --tailwind --app
cd ai-blog

Integrating AI APIs

There are several AI APIs you can integrate:

OpenAI API

Perfect for text generation, chatbots, and content creation.

Hugging Face

Great for various AI models including text-to-image and language processing.

Anthropic Claude

Excellent for conversational AI and complex reasoning tasks.

Example Implementation

Here's a simple example of integrating OpenAI's API:

// pages/api/generate.ts
import { NextApiRequest, NextApiResponse } from 'next';
import { Configuration, OpenAIApi } from 'openai';

const configuration = new Configuration({
  apiKey: process.env.OPENAI_API_KEY,
});

const openai = new OpenAIApi(configuration);

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

  try {
    const { prompt } = req.body;

    const completion = await openai.createCompletion({
      model: 'text-davinci-003',
      prompt,
      max_tokens: 100,
    });

    res.status(200).json({ result: completion.data.choices[0].text });
  } catch (error) {
    res.status(500).json({ error: 'Something went wrong' });
  }
}

Best Practices

1. Error Handling: Always implement proper error handling
2. Rate Limiting: Protect your API endpoints
3. Caching: Cache AI responses to reduce costs
4. Security: Never expose API keys on the client side

Conclusion

AI integration opens up exciting possibilities for web applications. Start small, experiment, and gradually incorporate AI features into your projects.
