Fix "Invalid DOM property `class`. Did you mean `className`?" in React

Resolve React console warnings when pasting raw SVG code directly into your JSX components.

The Problem (Error Root Cause)Exception

You copied an SVG from Figma or Illustrator and pasted it into a React component. The console is filled with warnings about `class`, `stroke-width`, and `fill-rule` being invalid DOM properties.

Identified via runtime validation & stack traces

The Solution (Step-by-Step Fix)Verified

React requires camelCase property names for DOM elements (e.g., `strokeWidth` instead of `stroke-width`). You must convert raw HTML/SVG attributes into valid JSX syntax.

Frequently Asked Questions

Q:Do I have to rename every property manually?

No, you can automate this. Using an SVG to JSX converter handles all camelCasing and tag closures for you.

Q:Why does React enforce camelCase?

React normalizes DOM attributes to match the standard JavaScript DOM API, which uses camelCase (like `element.className`).
