What this snippet does
Dev dependencies and source stay behind, shipping only the build output and runtime modules.
Expected output
listening on http://0.0.0.0:3000
Why practise typing this
Typing multi-stage builds code builds muscle memory for the symbols and indentation Docker uses most, which prose-based typing tests never cover. DevType measures your words per minute and accuracy on this snippet and tracks the individual characters you mistype, so later lessons can target them.
