  • Tip: use ghc-options: -dedupe -O2 to reduce size of resulted JS blob.
  • Tip: for production use Google Closure compiler with settings:
# Copy application JS blob
cp $(stack path --local-install-root)/bin/<packagename>.jsexe/{all.js,all.js.externs} .
# Copy all raw JS dependencies to not let optimizer to break your code
cp ../<packagename>-server/static/jquery-1.9.1.js .
cp ../<packagename>-server/static/bootstrap/js/bootstrap.min.js .
cp ../<packagename>-server/static/bootstrap/js/material.min.js .
cp ../<packagename>-server/static/bootstrap/js/ripples.min.js .
# Compile with aggressive optimizations and turned off duplicate/undefined errors
ccjs all.js --compilation_level=ADVANCED_OPTIMIZATIONS \
  --externs=node \
  --externs=all.js.externs \
  --externs=bootstrap.min.js \
  --externs=material.min.js \
  --externs=ripples.min.js \
  --jscomp_off=duplicate \
  --jscomp_off=undefinedVars \
  > all.min.js

This tears down 12 MB JS bundle to 1 MB and then you can transfer it with enabled gzip on server. That leads to 600 KB transferred to customer instead of original 12 MB.
