Can I pre-cache dependencies that I specify using npm:?

Hi! Trying to figure out the right way to combine Deno's module support to make our deploys consistent. In particular, I was using

esm.sh

esm.sh

esm.sh

esm.sh URLs, but just hit some CDN errors so that made me switch to

npm:

npm:

in hopes of it being more reliable. But afaict

deno vendor

deno vendor

deno vendor

deno vendor doesn't vendor npm dependencies? What's the right combination of things to do to deploy reliably?
