[1.7.0.4 ] Minify errors with dynamically imported server modules

[nabiltntn]

Hi,

i have recently upgraded my application from 1.5 to 1.7.0. 4

It uses packages structure like this :

The idea is to to separate mobile and web code when creating bundles. Both of them are declared with lazy: true

web

api.mainModule('client/index.js', 'web.browser', { lazy: true });

mobile

api.mainModule('client/index.js', 'web.cordova', { lazy: true });

In the api package, i am defining ValidatedMethods that import modules from server ( following Meteor Guide to hide secret server code ) like this :

export const aMethod = new ValidatedMethod({
  name: 'name',
  validate: SomeSchema.validator(),
  async run({ param1, param2 }) {
    if (Meteor.isServer) {
      const { functionFromServerModule: method } = await import('../../server/moduleWithFunction');
      return method.call(this, { param1, param2 });
    }
  }
});

To call these mthods from web and mobile package, i import them like this :

import { aMethod } from 'meteor/xxxxx:api/modules/module1/api';

In Dev, the application works fine , but when building or running with --production flag , i get errors due to minification.

I tried to verify the files that cause errors by displaying the input of standard-minifier-js pckage
and it seems like meteor does not transpile source from server modules imported dynamically inside functions like ../../server/moduleWithFunction ( copy them as they are with import, export, etc )

The result is the same when i replace standard-minifier-js with abernix:standard-minifier-js@2.1.0
