# Use `deno.json` configuration file in Edge Functions

Each Edge Function can now have its own `deno.json` or `deno.jsonc` file to manage dependencies. You will need to deploy your functions using Supabase CLI version v1.215.0 or above to make use of this feature.

### How to use `deno.json`

Create a `deno.json` in your function's folder:

```jsonc
// supabase/functions/function-name/deno.json
{
  "imports": {
    "lodash": "https://cdn.skypack.dev/lodash"
  }
}
```

You can now use aliased imports in your source code:

```ts
// supabase/functions/function-name/index.ts
import lodash from 'lodash'
```

To test your function locally, run `supabase functions serve`. When you're ready, you can deploy it to hosted platform by running `supabase functions deploy function-name`
