The JSXPreview component solves this challenge by rendering JSX strings as React components in real-time, with support for streaming content and automatic tag completion. The Problem with AI-Generated JSX AI models often generate JSX code incrementally, which can lead to incomplete tags and broken rendering. Traditional approaches require waiting for the complete output before rendering, creating a disjointed experience for users. Introducing JSX Preview Our JSXPreview component solves these problems with two key features: Direct JSX Rendering: Convert JSX strings to live React components Tag Completion: Automatically complete open tags during streaming Renders and previews generated JSX in real time, with streaming and tag completion. How It Works The component works through a combination of JSX parsing and intelligent tag completion: function JSXPreview({ jsx, isStreaming = false, ...props }: JSXPreviewProps) { const processedJsx = React.useMemo( () => (isStreaming ? completeJsxTag(jsx) : jsx), [jsx, isStreaming] ) // Cast JsxParser to any to work around the type incompatibility const Parser = JsxParser as unknown as React.ComponentType<JsxParserProps> return <Parser jsx={processedJsx} {...props} /> } When isStreaming is enabled, the component automatically balances opening and closing tags, allowing for real-time preview even with incomplete JSX input. Tag Completion Logic The core of our component lies in the completeJsxTag function: function completeJsxTag(code: string) { const stack: string[] = [] let result = "" let currentPosition = 0 while (currentPosition < code.length) { const match = matchJsxTag(code.slice(currentPosition)) if (!match) break const { tagName, type, endIndex } = match if (type === "opening") { stack.push(tagName) } else if (type === "closing") { stack.pop() } result += code.slice(currentPosition, currentPosition + endIndex) currentPosition += endIndex } return ( result + stack .reverse() .map((tag) => `</${tag}>`) .join("") ) } This function maintains a stack of open tags and automatically generates closing tags when needed, ensuring valid JSX even during streaming. Usage Examples Basic JSX Preview import { JSXPreview } from "@/components/jsxPreview"; export default function Example() { return ( <JSXPreview jsx="<div><h1>Hello World</h1><p>This is a preview</p></div>" /> ); } Streaming JSX Preview import { JSXPreview } from "@/components/jsxPreview"; import { useState, useEffect } from "react"; export default function StreamingExample() { const [jsx, setJsx] = useState(""); useEffect(() => { const fullJsx = "<div><h1>Hello World</h1><p>This is being streamed"; let current = ""; let index = 0; const interval = setInterval(() => { if (index < fullJsx.length) { current += fullJsx[index]; setJsx(current); index++; } else { clearInterval(interval); } }, 100); return () => clearInterval(interval); }, []); return <JSXPreview jsx={jsx} isStreaming={true} />; } Use Cases AI Code Generation The JSXPreview component is particularly useful when integrated with AI code generation tools: Real-time preview of AI-generated components Visual feedback during iterative code generation Interactive prototyping with AI assistance Credits This component was inspired by the work done at Prompt Kit, which offers various tools for working with AI-generated content.Keep exploringFree ToolsAI Calculators & Utilities ->ROI calculator, LLM cost estimator, workflow tools.Case StudiesReal-world AI builds ->See how we've shipped AI automation for real businesses.BlogMore posts ->Practical guides on AI, automation, and building fast.Maximal StudioAI & automation for builders.PagesToolsBlogCase StudiesApproachResourcesOfficeIndiaBangaluru, Karnataka, IndiaConnectLinkedInXEmail© 2026 Maximal Studio.
