## Dependency Inspector

`deno info [URL]` will inspect ES module and all of its dependencies.

Dependency inspector works with any local or remote ES modules.

## Cache location

`deno info` can be used to display information about cache location:

```shell
deno info
DENO_DIR location: "/Users/deno/Library/Caches/deno"
Remote modules cache: "/Users/deno/Library/Caches/deno/deps"
TypeScript compiler cache: "/Users/deno/Library/Caches/deno/gen"
```
