@nx/expo/docs/prebuild-examples.md

The Expo Plugin for Nx contains executors and generators for managing and developing an expo application within your workspace. For example, you can directly build for different target platforms as well as generate projects and publish your code.

The `prebuild` command generates native code before a native app can compile.

`project.json`:

```json
{
  "name": "mobile",
  //...
  "targets": {
    //...
    "prebuild": {
      "executor": "@nx/expo:prebuild",
      "options": {}
    }
    //...
  }
}
```

```shell
nx run mobile:prebuild
```

## Examples

##### Generate Native Code for Different Platforms

The `platform` option allows you to specify the platform to generate native code for (e.g. android, ios, all).

```json
    "prebuild": {
      "executor": "@nx/expo:prebuild",
      "options": {
        "platform": "android"
      }
    }
```

##### Regenerate Native Code

The `clean` option allows you to delete the native folders and regenerate them before apply changes.

```json
    "prebuild": {
      "executor": "@nx/expo:prebuild",
      "options": {
        "clean": true
      }
    }
```

##### Install NPM Packages and CocoaPods

The `install` option allows you to install NPM Packages and CocoaPods.

```json
    "prebuild": {
      "executor": "@nx/expo:prebuild",
      "options": {
        "install": true
      }
    }
```
