@privatenumber I don’t want to have some global variables in window. I’ve got a bug with window._ intersection before…

Are you using the minifier to transpile?

I didn’t know but used it as transpiler 😃 I missed node_modules when was building with esbuild-loader And then minifier transpiled my ...spread syntax with global functions.

So it’s okay to run without iife, but you should transpile all .js like files like this:

{
  // test: /\.tsx?$/, // doesn't transpile node_modules .js/.cjs/.mjs/etc.
  test: /\.[cm]?[jt]sx?$/,
  loader: 'esbuild-loader',
  options: {
    loader: 'tsx',
    target: 'es2015',
  },
},
