Babel error about json-diff-kit HOT 7 CLOSED

Hello, My error is slightly different but means the same:

node_modules/json-diff-kit/dist/index.js: Missing class properties transform.
  715 | // src/differ.ts
  716 | var Differ = class {
> 717 |   options;
      |   ^
  718 |   arrayDiffFunc;
  719 |   constructor({
  720 |     detectCircular: detectCircular2 = true,

I also added the package with npm install --save-dev @babel/plugin-proposal-class-properties and try to configure either my webpack config or even create a .babelrc file but nothing work.

Any idea ?
Thanks

This may be due to the compiled result by ESBuild. I'll investigate it later.

I didn't find the error in my example app created by the create-react-app.

Could you please provide more details, such as the .babelrc file, or a minimal example?

Found the same issue. `import { Differ, Viewer } from "json-diff-kit";
import "json-diff-kit/dist/viewer.css";

const differ = new Differ({
detectCircular: true, // default true
maxDepth: Infinity, // default Infinity
showModifications: true, // default true
arrayDiffMethod: "lcs", // default "normal", but "lcs" may be more useful
});
const diff = differ.diff(changeRequest.before, changeRequest.after);

    return (
      <Viewer
        diff={diff} // required
        indent={4} // default `2`
        lineNumbers={false} // default `false`
        highlightInlineDiff={true} // default `false`
        inlineDiffOptions={{
          mode: "word", // default `"char"`, but `"word"` may be more useful
          wordSeparator: " ", // default `""`, but `" "` is more useful for sentences
        }}
      />
    );`

@ipramono Can you provide your babel version and the babelrc file?

from json-diff-kit.

@RexSkz I don't have babelrc, and there's no babel in my package.json

I was also getting this error and it got resolved after I changed

"react": "^16.14.0",
"react-dom": "^16.14.0",
"react-scripts": "3.4.1",
to

"react": "^18.2.0",
"react-dom": "^18.2.0",
"react-scripts": "5.0.1",
"web-vitals": "^2.1.4",

in my package.json file
