Integrate Your Existing CI/CD Pipelines with Mobile Capabilities

Preparing Your CI/CD Environment

Once you’ve got the basics of CI/CD down, the next step is setting up your environment. This is the backbone of dependable automation.

Tools and Software Setup

Make sure you have these key tools installed:

For iOS Development:

• Xcode 14 or newer
• Xcode Command Line Tools
• CocoaPods for managing dependencies

For Android Development:

• Android Studio
• Android SDK 33 or above
• Java Development Kit (JDK)

To confirm your Xcode Command Line Tools are installed, use:

xcode-select -p

Creating a Capacitor Project

Your Capacitor project needs to be configured correctly for CI/CD workflows. The capacitor.config.ts file is at the heart of this setup:

const config: CapacitorConfig = {
  appId: 'com.example.app',
  webDir: 'build',
  ios: {
    scheme: 'MyApp'
  }
}

This file ensures your project aligns with CI/CD requirements.

Setting Up Environment Variables

Managing credentials securely is a key part of linking your environment setup with the CI/CD pipeline.

Key Variables to Define:

• BUILD_ENV: Specifies the deployment stage (e.g., production)
• IOS_SIGNING_IDENTITY: Your code signing certificate
• ANDROID_KEYSTORE_PATH: Path to your Android keystore

For Android builds, dynamically generate a local.properties file during the CI process:

echo "sdk.dir=$ANDROID_SDK_ROOT" > android/local.properties

When working with iOS builds, ensure your CI platform supports macOS agents.

To check if your environment is ready:

node --version | grep "v16" && xcodebuild -version | grep "Xcode 14" || exit 1

Properly managing keys and credentials can significantly lower the chances of app store rejections, as noted in earlier statistics [1].

Creating Your CI/CD Pipeline

Once your environment is ready, the next step is setting up a CI/CD pipeline for your Capacitor app. This pipeline should efficiently manage both web assets and native platform builds.

Installing and Updating Dependencies

In CI/CD environments, managing dependencies requires strict version control. Start with a clean installation process:

npm install --ignore-scripts
npm install @capacitor/cli

To speed up builds, use dependency caching. For instance, Azure DevOps users have seen build times improve by 40-60% with this setup:

- task: Cache@2
  inputs:
    key: 'npm | "$(Agent.OS)" | package-lock.json'
    path: |
      node_modules
      android/.gradle
      ios/Pods

iOS and Android Build Setup

Here’s how to configure builds for both platforms:

iOS Build Configuration:

steps:
  - task: InstallAppleCertificate@2
    inputs:
      certSecureFile: 'certificate.p12'
      certPwd: $(P12_PASSWORD)
  - script: |
      xcodebuild -workspace ios/App/App.xcworkspace -scheme App -configuration Release -archivePath ios/App/App.xcarchive archive

Android Build Configuration:

cd android
./gradlew bundleRelease

Testing and Deployment Steps

Run platform tests in parallel using a matrix strategy:

test:
  steps:
    - run: npm run test:unit
    - run: npm run test:e2e
    - name: Run Platform Tests
      matrix:
        platform: [ios, android]
      run: npm run test:${{ matrix.platform }}

For deployment, set up platform-specific artifact handling:

Using parallel builds can significantly cut down pipeline execution time when configured correctly.

Once your builds are validated and packaged, you’re ready to move on to live updates with Capgo (discussed in the next section).

Adding Capgo for Live Updates

Integrating Capgo into your workflow enhances your CI/CD process by enabling post-release updates. Here’s how to set it up:

Capgo Pipeline Configuration

First, install the Capgo CLI in your pipeline environment:

steps:
  - name: Install Capgo CLI
    run: npm install -g @capgo/cli
  - name: Configure Authentication
    env:
      CAPGO_KEY: ${{ secrets.CAPGO_API_KEY }}

This addition extends your CI/CD lifecycle by incorporating update management into your automated build and deployment process.

Next, include the upload command after your build steps:

- name: Upload Update
  run: |
    capgo upload --api-key $CAPGO_KEY --bundle ./build/app-release.apk
    capgo deploy v${VERSION} --channel production

For secure updates, configure validation settings like this:

{
  "verification": {
    "checksum": "strict",
    "certificatePinning": true,
    "updateTimeout": 500
  }
}

Capgo Features Overview

OTA Update Guidelines

Enhance your testing processes by tracking these key metrics after deployment:

Phased Deployment Strategy

Use a staged rollout to control how updates are distributed:

- name: Staged Rollout
  run: |
    capgo deploy v1.2.3 --group "beta-users" --rollout 10%
    capgo deploy v1.2.3 --rollout 50%

Update Monitoring

Keep an eye on these metrics:

• Adoption rate: Aim for 40-60% within the first 24 hours.
• Crash-free sessions: Maintain above 99.5%.
• Verification time: Ensure it’s under 500ms.

If crashes exceed acceptable levels, automate a rollback:

- name: Rollback Check
  run: |
    if [ $(capgo stats --version v1.2.3 --metric crashes) -gt 2 ]; then
      capgo rollback --channel production
    fi

Improving Pipeline Performance

Focusing on three key areas can lead to noticeable improvements in your pipeline:

Build Speed Optimization

For web-only changes, using npx cap sync can save time by skipping full native rebuilds, reducing rebuild time by about 40%. Here’s how you can implement conditional building:

- name: Build Strategy
  run: |
    [ "$WEB_ONLY" = true ] && npx cap sync || (./gradlew assembleRelease && xcodebuild ...)

This approach ensures that only the necessary components are rebuilt, streamlining the process.

Version Control Automation

Automating version control can simplify your workflow. Use the following script to set version and build numbers dynamically:

- name: Set Version
  run: |
    VERSION=$(node -p "require('./package.json').version")
    BUILD_NUMBER=$GITHUB_RUN_NUMBER
    echo "APP_VERSION=${VERSION}" >> $GITHUB_ENV
    echo "BUILD_ID=${BUILD_NUMBER}" >> $GITHUB_ENV

Additionally, automated semantic versioning can be set up with this configuration:

{
  "scripts": {
    "version": "standard-version",
    "build:prod": "npm version patch && ionic build --prod"
  }
}

These practices provide a solid framework for tracking and improving pipeline performance through metrics like:

• Build time per stage
• Cache efficiency (hit/miss ratios)
• Peak resource usage

Multi-Environment Setup

Managing multiple environments can be simplified by using environment-specific configurations. Here’s an example setup:

You can configure environments dynamically with this script:

- name: Configure Environment
  env:
    API_KEY: ${{ secrets.ENV_SPECIFIC_API_KEY }}
    BUNDLE_ID: ${{ parameters.bundleId }}
  run: |
    echo "ENVIRONMENT=${{ parameters.environment }}" >> $GITHUB_ENV
    echo "API_ENDPOINT=${{ parameters.apiUrl }}" >> $GITHUB_ENV

Pairing these configurations with Capgo’s channel-based deployment allows for precise, environment-specific updates. This ensures smoother rollouts and better control over application behavior in different environments.

Summary

CI/CD’s Role in Development

Using CI/CD pipelines for Capacitor apps significantly boosts workflow efficiency. According to industry data, teams can achieve 50-70% faster release cycles thanks to simultaneous iOS and Android builds [3]. Automating tasks like dependency installation and platform synchronization reduces deployment errors by 40-60% [1][2].

For instance, teams leveraging Azure DevOps pipelines have automated processes such as sequential build steps and Xcode packaging. They also use parameterized environments for both development and production. This approach removes the need for manual Gradle and Xcode CLI operations, ensuring reliable artifact creation every time.

These improvements lay the groundwork for streamlined update management when paired with Capgo.

Capgo for Update Management

Capgo works seamlessly with CI/CD pipelines to deliver instant updates while staying compliant with app store policies. Updates are only deployed after passing automated testing gates built into the pipeline.

By combining automated builds with phased rollouts, teams achieve impressive results: 80% user coverage within 7 days and rollback capabilities in under an hour.

A common strategy involves running parallel deployment tracks. Automated builds are used for internal testing, while phased rollouts target user segments. This ensures updates are both fast and safe, backed by rigorous automated testing gates [1].
