uglify-folder (in 2021, now?) supports passing in terser configs like so:

$ uglify-folder --config-file uglifyjs.config.json ...other options...

and with uglifyjs.config.json:

{
  "compress": {
    "drop_console": true
  }
}

And all options available here from the API reference.

Short Answer

Unfortunately, uglifyjs-folder does not provide an option to silence the logs.

Solution

You could consider writing a nodejs utility script which utilizes shelljs to:

  • Invoke the uglifyjs-folder command via the shelljs exec() method.
  • Prevent logging to console by utilizing the exec() methods silent option.

The following steps further explain how this can be achieved:

  1. Install

    Firstly, cd to your project directory and install/add shelljs by running:

    npm i -D shelljs

  1. node script

    Create a nodejs utility script as follows. Lets name the file: run-uglifyjs-silently.js.

    var path = require('path');
var shell = require('shelljs');

var uglifyjsPath = path.normalize('./node_modules/.bin/uglifyjs-folder');

shell.exec(uglifyjsPath + ' js -eyo build/js', { silent: true });

    Note: We execute uglifyjs-folder directly from the local ./node_modules/.bin/ directory and utilize path.normalize() for cross-platform purposes.

  2. package.json

    Configure the uglifyjs script inside package.json as follows:

    {
  ...
  "scripts": {
    "uglifyjs": "node run-uglifyjs-silently"
    ...
  },
  ...
}

  3. Running

    Run the script as per normal via the command line. For example:

    npm run uglifyjs

    Or, for less logging to the console, add the npm run --silent or shorthand equivalent -s option/flag. For example:

    npm run uglifyjs -s

Notes:

  • The example gist above assumes that run-uglifyjs-silently.js is saved at the top-level of your project directory, (i.e. Where package.json resides).

  • Tip: You could always store run-uglifyjs-silently.js in a hidden directory named .scripts at the top level of your project directory. In which case you'll need to redefine your script in package.json as follows:

    {
  ...
  "scripts": {
    "uglifyjs": "node .scripts/run-uglifyjs-silently"
    ...
  },
  ...
}
