## Reloading modules

By default, a module in the cache will be reused without fetching or
re-compiling it. Sometimes this is not desirable and you can force deno to
refetch and recompile modules into the cache. You can invalidate your local
`DENO_DIR` cache using the `--reload` flag of the `deno cache` subcommand. It's
usage is described below:

### To reload everything

```ts
deno cache --reload my_module.ts
```

### To reload specific modules

Sometimes we want to upgrade only some modules. You can control it by passing an
argument to a `--reload` flag.

To reload all \$STD_VERSION standard modules

```ts
deno cache --reload=https://deno.land/std@$STD_VERSION my_module.ts
```

To reload specific modules (in this example - colors and file system copy) use a
comma to separate URLs

```ts
deno cache --reload=https://deno.land/std@$STD_VERSION/fs/copy.ts,https://deno.land/std@$STD_VERSION/fmt/colors.ts my_module.ts
```
