What is JSX Viewer? 🧭

The JSX Viewer is a browser-based React preview tool. It transpiles JSX with Babel, finds a previewable component, and renders it directly in the page so you can inspect UI output quickly.

What can it do? ✅

Preview App, Preview, Component, or a pasted JSX fragment.
Format JSX with Prettier and view syntax diagnostics inline.
Load snippets, local files, or remote JSX/TSX source.
Optionally include the Tailwind CDN for utility-class previews.

How JSX Viewer works (Step-by-Step) 🪄

Step 1: Paste JSX or TSX into the editor.
Step 2: The page transpiles the source with Babel and detects the preview component.
Step 3: The preview panel renders the component and reports compile or runtime errors.

Options Explained

Tailwind CDN: enable utility classes in the preview panel.
Format: run Prettier against the current JSX source.
Refresh: remount the preview when component state needs a clean reset.

Common Errors

No previewable component found: define App, Preview, Component, or use a JSX fragment.
Unexpected token: check unclosed tags, missing braces, or TypeScript-only syntax.
Runtime error: component code can compile but still throw while rendering.

Limitations

External npm imports are stripped, so paste self-contained examples.
Heavy components can take longer to compile and render in the browser.
The preview is for visual validation, not a replacement for app-level tests.

Free vs Paid 💸

This tool is 100% free with no usage limits or account required. You can use it for quick conversions without subscriptions or payments.

Official vs Third-Party 🧪

Folioify provides this as a third-party utility. It does not replace official tools, but offers a fast, accessible alternative for everyday workflows.

Use Cases 💡

Debug a copied React component before adding it to a codebase.
Preview Tailwind UI snippets without opening a full app.
Validate JSX syntax in documentation, bug reports, or examples.
Share a quick visual check with designers or frontend teammates.

Frequently Asked Questions ❓

Can the JSX Viewer render a component without an App export?

Yes. It can render App, Preview, Component, the first PascalCase component, or a raw JSX fragment.

Does the JSX Viewer support Tailwind CSS?

Yes. Turn on the Tailwind CDN toggle to preview common Tailwind utility classes.

Why does my imported component not render?

The viewer strips module imports for safety and portability. Paste a self-contained component instead.
