Problem with latest CRA

[stereobooster]

Error only visible in production build: yarn build && serve -s build. In #207 I updated to the latest CRA, so you can check it (delete homepage field to test).

I suppose this is error in mapbox-gl and webworkify.

Uncaught ReferenceError: e is not defined

Having the same problem. Specifically, using latest CRA scripts (which switched to webpack 2), a map which works fine in development mode fails to display anything in a production environment.

Traceback, being minified, isn't that helpful:

Created a minimal repo showing this bug in action: https://github.com/davidascher/mapbox-repro-bug

[davidascher]

Filed bug on CRA in case the bug is over there: facebook/create-react-app#2376

[davidascher]

FYI, this was fixed with a workaround in CRA v. 1.0.7. Long fascinating thread about the root cause here mishoo/UglifyJS#2011 (comment) if you're curious. (still ongoing).

Thanks

[davidascher]

just for fun, bug is now traced back to mapbox/mapbox-gl-js#4359.
