deno cache

Purpose: Pre-download and compile remote dependencies along with their static imports, storing them in the local cache.

Usage:

  • Cache a specific module and its dependencies without executing any code: 
    deno cache https://deno.land/std/http/file_server.ts
    deno cache npm:express

Behavior:

  • Modules cached using deno cache are stored in $DENO_DIR, a centralized directory. Its location varies by OS. For instance, on macOS, it's typically /Users/ry/Library/Caches/deno. You can see the location by running deno info with no arguments.
  • Subsequent executions of cached modules don't require downloads or compilation, unless --reload is used to force updates.

This ensures faster execution times for scripts that have already been cached, by avoiding unnecessary network requests and recompilation.
