Webpack builds if I omit serve, so serve must be the issue. Or am I missing something?

The text was updated successfully, but these errors were encountered:

alexander-akait · 2021-04-24T13:42:22Z

This problem due this:

  resolve: {
    extensions: [".ts"],
  },

You disable js extensions, do not remove default values, please use ['ts', 'tsx', '...'], even more your can break a lot of other cases and break your app
