Standard Minifier for JS
========================
This package provides a minifier plugin used for Meteor apps by default. The behavior
of this plugin during a development build is that all JS files will not be minified,
they will include a source map, and are sent to the client as seperate files. The behavior
during a production build is that all JS files are concatenated into a single, minified JS
file and this file will not include a source map.
This package provides a minifier plugin used for Meteor apps by default.
The JS minifier package uses `Terser` version `4.6.6` as of `Meteor` version `1.10.1`. The options
we setting that differ from the default settings are the following:
The behavior of this plugin in development and production modes are depicted below
in the table.

The rest of the minification options are the default values that `Terser` uses out of the box.
Additionally, we are only making a single pass over the source in order to compress the
output and this could be something we want to increase in the future. JS files are only
minified during a production build and the extra time spent on a second or third pass
may be worth the improved compression.
It should also be noted that by default terser will make one pass while compressing
source code, but additional passes could be configured to increase compression.
