🚀 Integrating AI into Your React Application: A Practical Guide

#webdev #react #ai #api

Hey community! 👋

AI is everywhere these days—powering chatbots, recommendation engines, and even image generators. The best part? You can easily bring this power into your React apps without starting from scratch.

✅ 1. Decide Your AI Use Case

Before writing any code, figure out what you want to build:

✔ Chatbot (OpenAI, LangChain)
✔ Image generation (Stable Diffusion, OpenAI Image API)
✔ Sentiment analysis
✔ Recommendations

✅ 2. Choose an AI Provider

Some popular options:

-> OpenAI API (ChatGPT, GPT-4, DALL·E)

-> Hugging Face Inference API (NLP, vision models)

-> Google Gemini or Claude API

-> Custom ML Model hosted on AWS, Flask, or FastAPI

✅ 3. Install Dependencies

For OpenAI, install:


npm install openai axios

✅ 4. Set Up a Backend Proxy (Recommended)

Never expose your API keys in the frontend! Create a simple Express server:

// server.js
import express from 'express';
import axios from 'axios';
const app = express();
app.use(express.json());

app.post('/api/chat', async (req, res) => {
  const { message } = req.body;
  const response = await axios.post(
    'https://api.openai.com/v1/chat/completions',
    {
      model: 'gpt-4',
      messages: [{ role: 'user', content: message }]
    },
    { headers: { Authorization: `Bearer ${process.env.OPENAI_API_KEY}` } }
  );
  res.json(response.data);
});

app.listen(5000, () => console.log('Server running on port 5000'));

✅ 5. Connect Your React Frontend

Here’s a simple React component for your AI chatbot:

import { useState } from "react";
import axios from "axios";

function ChatBot() {
  const [input, setInput] = useState("");
  const [response, setResponse] = useState("");

  const handleSend = async () => {
    const res = await axios.post("/api/chat", { message: input });
    setResponse(res.data.choices[0].message.content);
  };

  return (
    <div>
      <h2>AI Chatbot</h2>
      <textarea value={input} onChange={(e) => setInput(e.target.value)} />
      <button onClick={handleSend}>Send</button>
      <p>{response}</p>
    </div>
  );
}

export default ChatBot;
