Introduction

• Continuous Integration (CI) CI automates code
  integration into a shared repository, detecting
  and addressing integration issues early through
  automated build and test processes.
• Continuous Deployment (CD) CD extends CI by
  automating the deployment of successfully tested
  code changes to production or staging
  environments, minimizing the time between
  development and end-user availability for
  quicker, more frequent releases.

Importance of CI/CD

• Early Issue Detection Identifying integration
  issues and errors early in the development
  process
• Faster Time to Market Accelerating the release
  cycle for quicker delivery of features and
  updates.
• Enhanced Collaboration Fostering a collaborative
  development environment and allowing concurrent
  work.
• Reduced Manual Errors Minimizing the likelihood
  of errors during build, test, and deployment.
• Risk Mitigation Mitigating the risk of deploying
  untested or faulty code to production.
• Scalability and Flexibility Adapting to projects
  of varying sizes and complexities

Ensuring code quality and reliability
Streamlining collaboration among developers
Reducing manual errors and deployment time

• Source code version control (e.g., Git)
• Automated builds triggered by code changes
• Running automated tests to ensure code integrity
• Continuous deployment to staging environments

CI/CD Workflow for React Native
7
Setting Up CI/CD for React Native

• Choosing a CI/CD platform (e.g., Jenkins, Travis
  CI, GitHub Actions)
• Configuration files (e.g., YAML) for defining
  CI/CD pipeline
• Integration with version control repositories

8
Automated Builds in CI

• Configuring build scripts for React Native
  projects
• Building both Android and iOS apps automatically
• Handling dependencies and third-party libraries

9
Automated Testing in CI

• Writing unit tests for React Native components
  and functions
• Integration of testing frameworks (e.g., Jest)
• Running tests in parallel for faster feedback

10

• Deploying to a staging environment for testing
• Conducting additional testing (e.g., integration
  testing, user acceptance testing)
• Collecting feedback from stakeholders

Challenges and Solutions

• Dealing with platform-specific differences
  (Android vs. iOS)
• Handling large codebases and long build times
• Ensuring consistency across development, testing,
  and production environments
