<details>

<summary>Versioning History</summary>

**API Version v2.0.0** - Introduced `environment` configuration option.

</details>

Configure the environment that Prisma is going to use. In this function, you can mutate the environment however you want: import files using [useEnv](/stable/modules/schema-creator/api-documentation.md#useenv-path-string), change the environment using `process.env` or run other logic. To configure your virtual environment, add these lines to your configuration object:

{% code title="prisma-util.config.mjs" %}

```javascript
export default {
    // Other configuration lines
    environment: async () => {
        // Your environment logic
    }
};
```

{% endcode %}
