Should the FROM statement on this line be referencing the base stage that has the production dependencies and not the dev stage?

In my example, it should reference the dev stage, which has the build tools. Ideally, production images shouldn't have build tools and dependencies in them. You'll see later that I manually copy a directory out of that image to ensure the build tools avoid the production image.
