One of our South American clients required a React Native mobile application that could be dynamically configured for different clients, allowing each to have its own branding, API configurations, and deployment setup. Additionally, the deployment process needed to be fully automated to ensure seamless and scalable delivery of both Android and iOS applications.
Client Challenges:
Manual Deployment Bottlenecks
The traditional deployment process was highly manual, time-consuming, and prone to errors. Each time a client requested an update, developers had to
01
Modify
Modify configurations manually.
02
Application
Build the application separately for Android and iOS.
03
Certificates
Handle signing keys, certificates, and provisioning profiles manually.
04
Uploads
Upload the builds to the Play Store and App Store.
This approach led to inefficiencies, delays, and inconsistencies, making scaling nearly impossible as the number of clients increased
Automation Challenges
Dynamic Configurations
Each client required unique branding, API endpoints, and environment variables.
Code Signing & Provisioning
Managing Android Keystores, iOS provisioning profiles, and certificates securely.
Automated CI/CD
Implementing a robust continuous integration and deployment (CI/CD) pipeline for Android and iOS.
Google Play & App Store Integration
Automating the upload of builds while ensuring compliance with store policies.
Solution: A Fully Automated Multi-Tenant Deployment Pipeline
To address these challenges, we implemented an automated CI/CD pipeline leveraging GitHub Actions and Fastlane for both Android and iOS.
API configuration
Clients first fill out a form, specifying their branding, API configurations, and other settings.
Firebase
The submitted data is stored in Firebase Firestore.
Deployment pipeline
When a build is triggered, the deployment pipeline fetches the stored configurations from Firestore.
Fetch
The fetched configuration is then used to update the respective configuration files dynamically before the build process starts
Dynamic and scalable.
This eliminates the need for separate .env files, making the process truly dynamic and scalable.
Android Deployment Automation with Fastlane & GitHub Actions
GitHub Actions Workflow:
A YAML-based workflow automates builds and deployments.
Gradle Build Automation:
The workflow ensures proper Java and Node.js environments before building the Android app.
Fastlane for Deployment:
Automates APK/AAB generation.
Uploads builds to Google Play’s internal testing track.
iOS Deployment Automation with App Store Connect API
GitHub Actions Workflow:
Automates code signing, provisioning profile generation, and building archiving.
Utilizes Apple’s App Store Connect API for managing provisioning profiles dynamically.
Fastlane for Deployment:
Handles app archive creation and export.
Uploads builds to TestFlight and the App Store.
Secure Key Management:
Used GitHub Secrets to store App Store Connect API keys securely.
Automated Versioning & Release Management
Semantic Versioning: Implemented an automatic versioning strategy based on Git tags.
Release Automation: GitHub Actions triggers deployments on merging to the main branch.
Changelog Generation: Automatically generates release notes based on commit messages.
Implementation & Optimization Strategies
To ensure efficiency and reliability, we introduced:
Parallel Execution:
Android and iOS builds run concurrently, reducing deployment time.
Error & Retry Mechanisms:
Workflows retry failed deployments to ensure minimal manual intervention.
Secure Credential Management:
Encrypted secrets store signing keys, API keys, and certificates securely.
Scalable Architecture:
The system supports an unlimited number of clients without manual configuration changes.
Business Impact & Results
90% Reduction in Deployment Time: Deployment that once took hours is now completed in minutes.
Eliminated Manual Errors: Consistent deployment pipelines reduce human mistakes.
Scalable & Multi-Tenant Ready: Each client’s app version is deployed without impacting others.
Seamless Store Integration: Automated uploads ensure compliance with Google Play and App Store
Benefits Provided
Faster Time-to-Market: Clients can release updates quickly without developer involvement.
Cost Savings: Reduced manual effort saves development and operations costs.
Improved Reliability: CI/CD ensures stable and predictable deployments every time.
Conclusion & Future Enhancements
By leveraging GitHub Actions and Fastlane, we successfully automated the deployment of a multi-tenant React Native application, enabling seamless and efficient app releases. This automation not only streamlined operations but also empowered the client to scale their offerings without additional deployment overhead.
Future Enhancements
AI-Powered Testing
Implement automated UI testing using AI to detect UI/UX issues.
Real-Time Monitoring
Integrate App Store and Play Store monitoring for crash reports and analytics.
Auto-Rollback on Failure
Implement intelligent rollback mechanisms for failed deployments.
This case study showcases how automation can transform mobile app deployment, improving efficiency, scalability, and reliability for businesses looking to scale their applications effortlessly.
