• The variable name NPM_ALIASES uses inconsistent naming convention. It should follow the pattern of other variables in this file and be named 'EDXAPP_NPM_ALIASES' to maintain consistency with the module prefix.

NPM_ALIASES:

playbooks/roles/edxapp/tasks/deploy.yml:324

• The variable reference NPM_ALIASES should be updated to match the consistent naming convention. If the variable is renamed to EDXAPP_NPM_ALIASES, this reference should be updated accordingly.

  with_dict: "{{ NPM_ALIASES }}"

Using the 'shell' module for npm commands is discouraged. Consider using the 'npm' module instead, which provides better error handling and idempotency: 'npm: name={{ item.key }}@{{ item.value }} path={{ edxapp_code_dir }} state=present'

Suggested change

	shell: >
	npm install {{ item.key }}@{{ item.value }} --no-save
	args:
	chdir: "{{ edxapp_code_dir }}"
	npm:
	name: "{{ item.key }}@{{ item.value }}"
	path: "{{ edxapp_code_dir }}"
	state: present

@ttak-apphelix:

1. There is no PR description, or related ticket. Can you provide more context?
2. This doesn't seem to have gone through internal review first.
3. When it is ready for external review, it may make sense for @dianakhuang to review. She is working on something similar, if this is for deployment of a private NPM dependency, but I'm not clear on the context.
