set "type": "module" in `package.json` breaks the build

It’ll get this error if you set the “type”: “module” in the package.json

node -r esbuild-register scripts/test.ts
internal/process/esm_loader.js:74
    internalBinding('errors').triggerUncaughtException(
                              ^

Thanks to @Savid 's comment, this was added in 3.4.0 : https://github.com/egoist/esbuild-register#experimental-loader-support

I’ve just been playing with ES modules recently and I’ve had some success with the suggestion from @danny-andrews;

esbuild-register-loader.mjs

const extensionsRegex = /\.ts$|\.tsx$/;

export async function load(url, context, defaultLoad) {
  if (extensionsRegex.test(url)) {
    const { source } = await defaultLoad(url, { format: 'module' });
    return {
      format: 'commonjs',
      source: source,
    };
  }
  // let Node.js handle all other URLs
  return defaultLoad(url, context, defaultLoad);
}

then run;

node --experimental-loader ./esbuild-register-loader.mjs -r esbuild-register scripts/test.ts
