Configurations[ΒΆ](#overwrite-native-configurations "Permanent link") You can automatically overwrite your native Android and iOS project configurations before building in [Capawesome Cloud](/). This is useful for modifying app identifiers, display names, version numbers, and other native configurations based on your build environment or branch. This guide shows you how to use [Trapeze](https://trapeze.dev/), a mobile app configuration tool, to automate native project modifications during the build process. ## Installation[ΒΆ](#installation "Permanent link") First, install Trapeze as a development dependency in your project: `[](#%5F%5Fcodelineno-0-1)npm install --save-dev @trapezedev/configure ` ## Configuration File[ΒΆ](#configuration-file "Permanent link") Create a configuration file named `capawesome.yml` in the root of your project. This file defines the native configurations you want to overwrite. Here's a basic example that modifies the App ID and display name: `[](#%5F%5Fcodelineno-1-1)platforms: [](#%5F%5Fcodelineno-1-2) android: [](#%5F%5Fcodelineno-1-3) packageName: com.example.myapp [](#%5F%5Fcodelineno-1-4) appName: My App [](#%5F%5Fcodelineno-1-5) ios: [](#%5F%5Fcodelineno-1-6) bundleId: com.example.myapp [](#%5F%5Fcodelineno-1-7) displayName: My App ` Platform-specific configurations Trapeze uses platform-specific keys for similar configurations. For example, Android uses `packageName` while iOS uses `bundleId`. Refer to the [Android](https://trapeze.dev/docs/Operations/android) and [iOS](https://trapeze.dev/docs/Operations/ios) operation guides for complete lists of available configurations. ## Build Script[ΒΆ](#build-script "Permanent link") Add an npm script to your `package.json` that runs Trapeze for Android and iOS platforms before the web build process: `[](#%5F%5Fcodelineno-2-1){ [](#%5F%5Fcodelineno-2-2) "scripts": { [](#%5F%5Fcodelineno-2-3) "capawesome:build": "if [ \"$CI_PLATFORM\" = \"ios\" ] || [ \"$CI_PLATFORM\" = \"android\" ]; then npx trapeze run capawesome.yml -y --$CI_PLATFORM; fi && npm run build" [](#%5F%5Fcodelineno-2-4) } [](#%5F%5Fcodelineno-2-5)} ` Capawesome Cloud automatically calls the [web build script](/docs/cloud/native-builds/web-build-script/) during the build process. The script conditionally runs Trapeze only for iOS and Android platforms using the `$CI_PLATFORM` environment variable. ## Using Environment Variables[ΒΆ](#using-environment-variables "Permanent link") You can use Capawesome Cloud's [environment variables](/docs/cloud/native-builds/environments/) to dynamically configure your native projects. This is particularly useful for overwriting configurations based on your build environment. ### Define Variables[ΒΆ](#define-variables "Permanent link") First, define variables in your configuration file: `[](#%5F%5Fcodelineno-3-1)vars: [](#%5F%5Fcodelineno-3-2) APP_ID: [](#%5F%5Fcodelineno-3-3) APP_NAME: [](#%5F%5Fcodelineno-3-4) [](#%5F%5Fcodelineno-3-5)platforms: [](#%5F%5Fcodelineno-3-6) android: [](#%5F%5Fcodelineno-3-7) packageName: $APP_ID [](#%5F%5Fcodelineno-3-8) appName: $APP_NAME [](#%5F%5Fcodelineno-3-9) ios: [](#%5F%5Fcodelineno-3-10) bundleId: $APP_ID [](#%5F%5Fcodelineno-3-11) displayName: $APP_NAME ` ### Set Variable Values[ΒΆ](#set-variable-values "Permanent link") Then, set the variable values in your Capawesome Cloud environment: 1. Navigate to the [Environments](https://console.cloud.capawesome.io/apps/%5F/environments) page 2. Select your environment or create a new one 3. Add variables with their values: 4. `APP_ID`: `com.example.myapp` 5. `APP_NAME`: `My App` You can create multiple environments with different values (e.g., development, staging, production) and select the appropriate environment when triggering a build. Default values You can provide default values for variables that will be used if no environment variable is set: `[](#%5F%5Fcodelineno-4-1)vars: [](#%5F%5Fcodelineno-4-2) APP_ID: [](#%5F%5Fcodelineno-4-3) default: com.example.default [](#%5F%5Fcodelineno-4-4) APP_NAME: [](#%5F%5Fcodelineno-4-5) default: Default App Name ` May 7, 2026 Back to top
