React X-Ray AI

React X-Ray AI helps you understand a React codebase by finding the right file, reading it in context, and answering with a focused analysis instead of a generic chat response.

It is designed for new developers, reviewers, and anyone who wants a fast explanation of how a component works, how data flows through it, or whether there are obvious performance or security concerns.

Real Benefit

• if you want to do the same with normal github Copilot it costs you more token and Tokens are the real Wealth Present World😁.

What It Can Do

React X-Ray AI provides five focused analysis modes:

• flow - trace how a user action moves through handlers, state, API calls, and the final UI update.
• performance - spot likely React performance issues such as expensive rerenders, repeated calculations, and unstable references.
• security - highlight common front-end security risks such as XSS, unsafe HTML rendering, and sensitive data stored in the wrong place.
• onboarding - show a practical reading path for someone new to the project.
• review - give a PR-style review with maintainability, performance, and security feedback.

How To Use It

There are two easy ways to use React X-Ray AI.

Chat participant

Open the VS Code chat and mention the participant directly:

@react-x-ray /flow

You can also ask for a specific file or component:

@react-x-ray analyze the file named Header

Command Palette shortcuts

React X-Ray AI also registers convenient commands in the Command Palette. These copy a ready-made prompt to the clipboard and open editor chat for you.

• React X-Ray: End-to-End Flow Analyzer
• React X-Ray: React Performance Auditor
• React X-Ray: Security Scanner
• React X-Ray: New Developer Onboarding Mode
• React X-Ray: AI Pull Request Reviewer

Example Prompts

End-to-end flow analysis

@react-x-ray /flow

Use this when you want to understand the path from a click or event to the API call, state update, and final render.

Performance review

@react-x-ray /performance

Use this to check for rerender hot spots, expensive computations, and patterns that may slow the UI down.

Security scan

@react-x-ray /security

Use this to look for unsafe rendering, token handling problems, or other front-end security risks.

Onboarding help

@react-x-ray /onboarding

Use this when you are new to the repo and want the most useful files and flows to read first.

PR-style review

@react-x-ray /review

Use this when you want a concise code review with clear issues and suggested fixes.

What To Expect In The Response

The answer is tailored to the selected mode:

• Flow analysis explains the trigger, the handler chain, the data path, and the final render.
• Performance analysis summarizes likely hot spots and suggests targeted fixes.
• Security analysis reports practical front-end risks and how to reduce them.
• Onboarding mode gives a reading order and the critical application flows to understand first.
• Review mode returns a maintainability-oriented verdict with issues grouped by importance.

Supported Files And Search Behavior

The extension focuses on common React source files:

• .ts
• .tsx
• .js
• .jsx

It intentionally avoids build output and dependency folders so the analysis stays focused on your app code.

If the prompt names a file or component and no match is found, React X-Ray AI will tell you to open the file you want analyzed or mention its name more directly.

Why This Extension Is Useful

React codebases often have the same recurring problem: the hard part is not asking for help, it is finding the right file and understanding how the pieces connect. React X-Ray AI reduces that friction by locating a relevant React file, summarizing the important signals, and then answering in a mode that matches your goal.

That makes it useful for quick comprehension, onboarding, targeted audits, and lightweight review work.
