Comment 3 for bug 1952681

Discourse uses its own precompile scripts so the config.assets.js_compressor setting has no effects. Discourse (<= 2.7.13) will only start to use terser to compress JS assets under these three conditions:

  1. the uglifyjs command exists in $PATH
  2. the terser command exists in $PATH
  3. SKIP_NODE_UGLIFY environment variable not set

The correct package to install terser with command line tools is the uglifyjs.terser instead of node-terser. Also, the current base image 20.04 only provides an older version of the uglifyjs.terser package which only installs a command called uglifyjs.terser, so manually creating the terser command is required for now.
