# Configuration

## Environment Variable Configuration

The project's environment variable configuration is located in the application directory under `.env`, `.env.development`, `.env.production`.

The rules are consistent with [Vite Env Variables and Modes](https://vitejs.dev/guide/env-and-mode.html). The format is as follows:

```bash
.env                # Loaded in all environments
.env.local          # Loaded in all environments, but ignored by git
.env.[mode]         # Only loaded in the specified mode
.env.[mode].local   # Only loaded in the specified mode, but ignored by git
```

::: tip

- Only variables starting with `VITE_` will be embedded into the client-side package. You can access them in the project code like this:

  ```ts
  console.log(import.meta.env.VITE_PROT);
  ```

- Variables starting with `VITE_GLOB_*` will be added to the `_app.config.js` configuration file during packaging. :::

## Dynamic Configuration in Production Environment

When executing `pnpm build` in the root directory of the monorepo, a `dist/_app.config.js` file will be automatically generated in the corresponding application and inserted into `index.html`.

`_app.config.js` is a dynamic configuration file that allows for modifications to the configuration dynamically based on different environments after the project has been built. The content is as follows:

```ts
window._VBEN_ADMIN_PRO_APP_CONF_ = {
  VITE_GLOB_API_URL: 'https://mock-napi.vben.pro/api',
};
Object.freeze(window._VBEN_ADMIN_PRO_APP_CONF_);
Object.defineProperty(window, '_VBEN_ADMIN_PRO_APP_CONF_', {
  configurable: false,
  writable: false,
});
```

### Purpose

`_app.config.js` is used for projects that need to dynamically modify configurations after packaging, such as API endpoints. There's no need to repackage; you can simply modify the variables in `/dist/_app.config.js` after packaging, and refresh to update the variables in the code. A `js` file is used to ensure that the configuration file is loaded early in the order.

### Usage

To access the variables inside `_app.config.js`, you need to use the `useAppConfig` method provided by `@vben/hooks`.

```ts
const { apiURL } = useAppConfig(import.meta.env, import.meta.env.PROD);
```

### Adding New

To add a new dynamically modifiable configuration item, simply follow the steps below:

- First, add the variable that needs to be dynamically configurable in the `.env` file or the corresponding development environment configuration file. The variable must start with `VITE_GLOB_*`, for example:

  ```bash
  VITE_GLOB_OTHER_API_URL=https://mock-napi.vben.pro/other-api
  ```

- In `packages/types/global.d.ts`, add the corresponding type definition, such as:

  ```ts
  export interface VbenAdminProAppConfigRaw {
    VITE_GLOB_API_URL: string;
    VITE_GLOB_OTHER_API_URL: string; // [!code ++]
  }

  export interface ApplicationConfig {
    apiURL: string;
    otherApiURL: string; // [!code ++]
  }
  ```

At this point, you can use the `useAppConfig` method within the project to access the newly added configuration item.

```ts
const { otherApiURL } = useAppConfig(import.meta.env, import.meta.env.PROD);
```

::: warning Warning

The `useAppConfig` method should only be used within the application and not be coupled with the internals of a package. The reason for passing `import.meta.env` and `import.meta.env.PROD` is to avoid such coupling. A pure package should avoid using variables specific to a particular build tool.

:::

## Preferences

The project offers a wide range of preference settings for dynamically configuring various features of the project:

![](/guide/preferences.png)

If you cannot find documentation for a setting, you can try configuring it yourself and then click `Copy Preferences` to override the project defaults. The configuration file is located in the application directory under `preferences.ts`, where you can override the framework's default configurations to achieve custom settings.

```ts
import { useAppConfig } from '@vben/hooks';
import { defineOverridesPreferences } from '@vben/preferences';

/**
 * @description Project configuration file
 * Only a part of the configuration in the project needs to be covered, and unnecessary configurations do not need to be covered. The default configuration will be automatically used
 */
export const overridesPreferences = defineOverridesPreferences({
  // overrides
});
```

- The `overridesPreferences` method only needs to override a part of the configurations in the project. There's no need to override configurations that are not needed; they will automatically use the default settings.
- Any configuration item can be overridden. You just need to override it within the `overridesPreferences` method. Do not modify the default configuration file.
