@svgr/webpack with `jsxRuntime: 'classic-preact'` emits `React` namespace usage

Author: jet2jetCreated Feb 1, 2026Updated Feb 1, 2026

Bug Report

When using jsxRuntime: 'classic-preact' option in @svgr/webpack, emitted module includes React namespace reference which is not defined by default.

To Reproduce

Use @svgr/webpack
Configure webpack.config for .svg file to use @svgr/webpack with jsxRuntime: 'classic-preact':

javascript

    rules: [
      {
        test: /\.svg$/i,
        use: {
          loader: '@svgr/webpack',
          options: {
            jsxRuntime: 'classic-preact',
          }
        }
      }
    ]

Build files

Expected behavior

svg modules uses preact-related API only

(Actual behavior: svg modules uses React.createElement instead of preact API)
