Avoid using NPM in scripts NPM creates an extra layer of processes in containers which [do not properly forward signals](https://github.com/npm/npm/issues/4603). This can cause problems starting/stopping containers quickly. Additionally NPM tries to write to the filesystem as part of its self-update check. We would like to move to read only root container filesystems (using `read_only: true` in docker-compose.yml), so the easiest way to work around this NPM "feature" is to avoid using NPM. 7 years ago			`compose_run 'placeholder' ./cmd/extract.sh;`
