Dockerfile.assets-framework

# The framework-mode (react-router.config.ts) assets image, built only when BUILD_FRAMEWORK is set in CI while the
# migration is in progress. It is a standalone build: it compiles the framework build itself instead of starting from
# the app image, because the app image doesn't contain it.
#
# The build is made against a placeholder asset host. When the container starts it takes a fresh copy of the build and
# swaps in $ASSETS_HOST (or nothing, for same-origin assets), so one image serves any deployment. The app container
# needs the same ASSETS_HOST. With RAILS_UPSTREAM set, the container also proxies the Rails routes and crawlers to Rails.
ARG NODE_VERSION=26.13.0
# Optional: an earlier intercode-assets-framework image whose hashed files are carried over, as in Dockerfile.assets.
