# Collect production assets. By default, only assets from the default theme
# will be processed. This makes the docker image lighter and faster to build.
# To compile assets from other themes, build the image with the THEMES
# argument: THEMES=dark-theme,edx.org
# Custom themes added to /openedx/themes can also be compiled.
# Here, we don't run "paver update_assets" which is slow, compiles all themes
# and requires a complex settings file. Instead, we decompose the commands
# and run each one individually to collect the production static assets to
# /openedx/data/staticfiles.
# 1. xmodule_assets: run xmodule.static_content.main, which lists all xblocks and generates webpack manifest in common/static/xmodule
# 2. pavelib.assets.process_npm_assets: copy libraries installed via npm to common/static/common/*/vendor
# 3. webpack: generate webpack-stats.json
# 4. compile_sass: compile each sass file individually with libsass.
# 5. pavelib.assets.collect_assets: run ./manage.py lms/cms collectstatic. This is the only command that requires a settings file.
