deno cache import map

[nik-webdevelop]

It would be nice to have an option to cache remote modules from import map (deno.json:imports or import_map.json). Something like deno cache --import-map would be great.

I like to have my modules in import map and not create deps.ts. It works fine but there is one major limitation. It is impossible to utilize Docker layer caching for RUN deno cache.

COPY . /app
# files will always be different, so `deno cache` will always run
RUN deno cache index.ts

It would be nice to have something like this:

COPY ./deno.json /app
# `deno cache --import-map` will run only on `deno.json` change
RUN deno cache --import-map
COPY --exclude=./deno.json . /app
