## Composer - deps always cached unless changed
# First copy only composer files
COPY composer.* /code/
# Download dependencies, but don't run scripts or init autoloaders as the app is missing
RUN composer install $COMPOSER_FLAGS --no-scripts --no-autoloader
# copy rest of the app
COPY . /code/
# run normal composer - all deps are cached already
RUN composer install $COMPOSER_FLAGS
