- Creates production source maps
- Creates source maps for Meteor packages that don't use a compiler
- Very fast by using the swc minifier, a faster js parser, and disk and memory caches
- Compatible with Meteor 1.9 and newer. For Meteor 1.4 - 1.5, use
zodern:email@example.com production source maps, and for Meteor 1.6 - 1.8 use
- Generates bundle stats for bundle-visualizer
First, you need to remove
standard-minifier-js from your app
meteor remove standard-minifier-js
Then add this package with:
meteor add zodern:standard-minifier-js
If you want to prevent access to the source maps, you can add the
zodern:hide-production-sourcemaps package. Source maps include the original content from all of your client files, so you probably want to do this step.
meteor add zodern:hide-production-sourcemaps
Source maps allow error tracking services to show you better stack traces. I run Monti APM which provides an error tracking service and can use your app's source maps with no additional config.
To use with other error tracking services, you will need to upload the source maps when deploying. The source map is saved in the bundle from
meteor build at
programs/<arch>/<filename>.js.map. You will want to upload the source maps for each web arch, and for the dynamic imports for each arch.
When deploying from CI, you will need to configure the CI to cache at least parts of the
.meteor/local folder for the minify cache to work. Learn more at this blog post.
DISABLE_CLIENT_STATS Set to
true to disable creating the
stats.json file used by the bundle-visualizer. This can save a few seconds during production builds for large apps.
METEOR_FASTMINIFIER_CACHE_DEBUG Set to
true to view the cache logs
