The package works perfectly in a local dev environment but when I deploy to Heroku, I get the following error:
Uncaught ReferenceError: e is not defined

Here is the full stack trace:

@taystu It an known issue with mapbox-gl and Uglify.
You have a detailed explanation of the issue here: https://github.com/mapbox/mapbox-gl-js/issues/4359#issuecomment-303880888
And here: https://github.com/mishoo/UglifyJS2/issues/2520#issuecomment-347342508

And a correct way to solve it: https://github.com/angular/angular-cli/pull/7931#issuecomment-348032708

To sum it up, just set typeofs : false to Uglify options.

It was an issue with v2.0.0 of standard-minifier-js and probably UglifyJS2. Downgrading to v1.2.3 solves this issue for now.

Can you be more specific on how have you resolved this issue

mario-jerkovic on 28 Apr 2017

@mario-jerkovic I am using this library in a Meteor app. I downgraded my standard-minifier-js meteor package to v1.2.3 to resolve the issue.

@mario-jerkovic Did you find a solution? Thanks!

@andrea689
After a lot of debugging I have figure out that UglifyJsPlugin was causing this error to occur, so I have removed new webpack.optimize.AggressiveMergingPlugin() and set UglifyJsPlugin like this:
new webpack.optimize.UglifyJsPlugin({ compress: false })

Hi @mario-jerkovic I'm still getting this issue did you make any more changes to your webpack build? Also mind sharing your versions of react-mapbox-gl and webpack?

Thanks
