Introduction
AI-powered code generation is revolutionizing how developers work. In this post, we'll explore how to build your own AI code generation tool using modern APIs and frameworks.
Setting Up the AI Client
First, let's set up a client to interact with AI APIs. Here's a clean TypeScript implementation:
AI Code Generation Client
1import OpenAI from 'openai';
2
3const openai = new OpenAI({
4apiKey: process.env.OPENAI_API_KEY,
5});
6
7export async function generateCode(prompt: string) {
8const completion = await openai.chat.completions.create({
9 model: 'gpt-4',
10 messages: [
11 {
12 role: 'system',
13 content: 'You are an expert code generator. Generate clean,
14 well-commented code.',
15 },
16 {
17 role: 'user',
18 content: prompt,
19 },
20 ],
21 temperature: 0.7,
22});
23
24return completion.choices[0].message.content;
25}AI Code Explanation
Building a React Component
Now let's create a React component that uses this AI client:
React Code Generator Component
1'use client';
2
3import { useState } from 'react';
4import { Button } from '@/components/ui/button';
5import { Textarea } from '@/components/ui/textarea';
6
7export function CodeGenerator() {
8const [prompt, setPrompt] = useState('');
9const [generatedCode, setGeneratedCode] = useState('');
10const [loading, setLoading] = useState(false);
11
12const handleGenerate = async () => {
13 setLoading(true);
14 try {
15 const response = await fetch('/api/generate-code', {
16 method: 'POST',
17 headers: { 'Content-Type': 'application/json' },
18 body: JSON.stringify({ prompt }),
19 });
20 const data = await response.json();
21 setGeneratedCode(data.code);
22 } catch (error) {
23 console.error('Failed to generate code:', error);
24 } finally {
25 setLoading(false);
26 }
27};
28
29return (
30 <div className="space-y-4">
31 <Textarea
32 value={prompt}
33 onChange={(e) => setPrompt(e.target.value)}
34 placeholder="Describe the code you want to generate..."
35 />
36 <Button onClick={handleGenerate} disabled={loading}>
37 {loading ? 'Generating...' : 'Generate Code'}
38 </Button>
39 {generatedCode && (
40 <CodeBlock code={generatedCode} language="typescript" />
41 )}
42 </div>
43);
44}Best Practices
- Error Handling: Always wrap AI API calls in try-catch blocks
- Rate Limiting: Implement rate limiting to prevent abuse
- Validation: Validate generated code before execution
- Security: Never execute untrusted code directly
Conclusion
AI code generation tools can significantly boost developer productivity. By combining modern AI APIs with clean React components, you can build powerful tools that help developers write better code faster.
