Appflow provides an auto-incrementing environment variable (
CI_BUILD_NUMBER) that can be used with Trapeze to increment build numbers for the native builds of Capacitor apps.
An app demonstrating this feature can be found here.
To use this feature, first install
@trapezedev/configure project into your app:
npm install @trapezedev/configure
Platform flags (
--android) are only available in Trapeze v7.0.7+.
Next, create a simple
appflow.yml file with the following contents:
Finally, add the
appflow:build script to your npm scripts in
package.json to run this configuration during an Appflow build:
"appflow:build": "if [ \"$CI_PLATFORM\" != \"web\" ]; then npx trapeze run appflow.yml -y --$CI_PLATFORM; fi && npm run build",
$CI_PLATFORM environment variable dynamically resolves to the platform name of the currently running build (either
--android flags tell Trapeze to run the specified platform only. Since Appflow only builds one platform at a time, combining these features effectively allows us to use one Trapeze script containing both iOS and Android commands in Appflow.
Make sure to keep your build command as the second part of the
appflow:build script to ensure your app web assets build properly.
Setting Initial Build Number
If you'd like to start incrementing at a certain number, use the following
appflow:build command instead, substituting your initial build number for the number
1234. All subsequent build numbers will be added to this number:
"appflow:build": "CI_BUILD_NUMBER=$(($CI_BUILD_NUMBER + 1234)); if [ \"$CI_PLATFORM\" != \"web\" ]; then npx trapeze run appflow.yml -y --$CI_PLATFORM; fi && npm run build"
