Unable to load Meteor site in Safari/Firefox (Works fine in Chrome/Edge)

[Nexus7]

Hey all,

We are having a serious production issue with our Meteor 1.3 (and now 1.4) application when trying to access it from Safari or Firefox. The current production version of our application works fine under Meteor 1.2.1 on both Chrome and Safari.

We are now using version 1.4 of Meteor and the following are a sample of the many 'undefined' errors we see in the browser console:

However we don't see any of these issues in Chrome or even Microsoft Edge browser... Any ideas please?

Thanks

Ok, looks like I have found the source of this error in one of our npm packages that we are using. In the index.js of the package it has a "use strict" at the top of the file and then uses the const keyword in the file after that. It seems that this causes issues with Safari so for now we are reverting back a couple of commits on this npm package to before they introduced this change...

Hope that helps anyone else who has this problem...

Cheers
Rick

I had one (one!) package where I'd forgotten to add api.use('ecmascript') in the package.js file. This resulted in similar errors in phantomjs.

TypeError: undefined is not an object (evaluating 'Package['my-package'].MyObject')

Just had the same issue. Deleted cookies & other data in the browser and it worked again, no idea why.

For the record, I had a very similar issue after upgrading to Meteor 1.7.
The app was working fine on current Chrome, Firefox, but neither on Safari Desktop <11 and Safari on latest iOS <11.3 nor on Edge 18 or on Samsung Internet on my Android phone.

Totally blank page, and none of my client code was run.
The first error line before the "TypeError: undefined is not an object (evaluating 'Package.modules.meteorInstall')" was SyntaxError: Unexpected identifier: 'index' in modules.js, on the line let index = 0.
I tried to use the new function setMinimumBrowserVersions() to make sure the non-working versions of Safari were treated as 'legacy', without any success.

In the Safari debugger, I found out that the error was from browser.js in the npm module 'debug', which was a dependency of 'needle' which was a dependency of 'node-pre-gyp' which was dependency of... 'bcrypt'. It turns out I had installed the bcrypt package to get rid of the message that my server always displayed at startup:
Note: you are using a pure-JavaScript implementation of bcrypt. While this implementation will work correctly, it is known to be approximately three times slower than the native implementation. In order to use the native implementation instead, run meteor npm install --save bcrypt

Removing bcrypt (and getting that message back) fixed the issue on the legacy browsers!
