zodern:standard-minifier-js is a fork of standard-minifier-js that is able to generate production sourcemaps.
First, you need to uninstall standard-minifier-js
meteor remove standard-minifier-js
Then install this fork with:
meteor add zodern:standard-minifier-js
Starting in version 3, the javascript file is no longer named app.js. Instead, Meteor decides the file name, which is consistent with what standard-minifier-js does.
The sourcemap is saved in the bundle from meteor build or meteor --production at programs/web.browser/<filename>.js.map. The bundle from meteor --production is in .meteor/local/build.
If you want to prevent access to the sourcemaps, you can add the zodern:hide-production-sourcemaps package.
meteor add zodern:hide-production-sourcemaps
Known problems:
- Minifying takes a lot longer
