Using react-native-svg-transformer with react-native-sass-transformer

[celandro]

I am attempting to use both of your libraries together and getting the following error message: The current error I am getting is Can't find variable: $RefreshReg$

Implementation based on https://github.com/kristerkari/react-native-css-modules/blob/master/docs/multiple-transformers.md#step-3-configure-transformer

metro.config.js
const { getDefaultConfig } = require("metro-config");

module.exports = (async () => {
  const {
    resolver: { sourceExts, assetExts  }
  } = await getDefaultConfig();
  return {
    transformer: {
      getTransformOptions: async () => ({
        transform: {
          experimentalImportSupport: false,
          inlineRequires: false
        }
      }),
      babelTransformerPath: require.resolve("./transformer.js")
    },
    resolver: {
      assetExts: assetExts.filter(ext => ext !== "svg"),
      sourceExts: [...sourceExts, "svg", "scss", "sass"]
    }
  };
})();

transformer.js
var sassTransformer = require("react-native-sass-transformer");
var svgTransformer = require("react-native-svg-transformer");

module.exports.transform = function({ src, filename, options }) {
    if (filename.endsWith(".scss") || filename.endsWith(".sass")) {
        return sassTransformer.transform({ src, filename, options });
    } else
    return svgTransformer.transform({ src, filename, options });
};

Ive tried 0.54.1 for metro and it still had the issues

[kristerkari]

Hmm... I have not seen that error before. Maybe something related to Expo?

[celandro]

No clue. The sass transformer works great.
