Error on migration from Meteor 2.14.0 to 3.0-beta.6

3.0 migration
1

Hi guys, I just started to migrate an application from 2.14.0 version to 3.0-beta.6. I already did a lot of updates in some packages I use, and they are seeing fine. But I’m getting an weird error when I start the app. The line of that the error is indicating is a declaration of a global variable. I guess can be something easy to solve (at this moment I use a global variable for many things). CODE:

import SimpleSchema from "simpl-schema";

App = {}

ERROR:

> app@0.0.1 start
> meteor run --settings .deploy/dev/dev.settings.json

are you able to change:

App = {}

to

const App = {}

I would love to see a reproduction so that I can test it and maybe get into a solution for this package.

If I put const it is not more a global variable. I’m trying to create a reproduction code. For now, just in my project.

Oh, if you use globalThis it could work from what I understand.

globalThis.App = {}
