Common Codebase vs. Separate Codebase for Web and Mobile: Streamlining Your Platform Development

As developers and companies seek cost-effectiveness in the software industry, they face a strategic decision: should you have one set of code that works across your websites and mobile app, or separate code for each? This decision can impact your project's agility, costs, and scalability.

Each approach comes with its own advantages and disadvantages, which we will be exploring throughout this blog.

What is a Common Codebase?

A common codebase is a single set of source code that is used to create programs for several platforms, such as web, mobile, and desktop. It simplifies the development system by reducing its expenses and achieving efficiency. This codebase lets in a single team to manage and enhance all versions of an app at the same time, compared to having different teams for each. This saves time and resources while maintaining similar functionality and user experiences across all devices.

Frameworks like React Native, Flutter, Xamarin, Apache Cordova and Progressive Web Apps (PWA) have empowered developers to build apps that can be used on either web or mobile platforms using a single codebase. This is both cost-saving and resource-saving as users are able to use this across all devices while retaining the same functionality and user experience.

How Can a Common Codebase Benefit Your Development Process?

• Cost Efficiency: Common code across platforms eliminates the need for several development teams, resulting in much lower development and maintenance expenses.
  
  
• Reduced Development Time: When modifications are introduced once and redundant across all platforms, development time is reduced. This enables more frequent updates and releases.
  
  
• Consistency Across Platforms: A standard codebase ensures that every user, regardless of device or platform, has the same experience.
  
  
• Simplification: With only one codebase to manage, managing projects becomes easier, minimizing the complexity of tracking progress and coordinating teams.
  
  
• Easier Maintenance: Updates, bug fixes, and new features only have to be applied once, making maintenance easier and keeping all platforms in sync.
  
  
• Resource Optimization: Developers can concentrate on a single set of technologies and code, allowing for more efficient resource allocation and potentially reducing the need for specialized knowledge.
  
  
• Faster Learning Curve: Getting ne­w developers up to spe­ed is quick and easy, as they only have­ to learn one codebase­ that streamlines onboarding for new te­am members.
  
  
• Agility and Flexibility: Working with a common codebase­ aligns well with agile deve­lopment practices, empowe­ring teams to pivot rapidly and adapt to changes as require­d.
  
  
• Scalability: As your application grows, a common codebase allows you to scale functionality and support an e­xpanding user base across multiple platforms se­amlessly.
  
  
• Community and Support: Robust community support is available for popular common code base frameworks, providing a wealth of troubleshooting resources and learning opportunitie­s.

What are the Challenges When Using a Common Codebase?

• Performance Issues: Apps built from a common codebase may not always perform on native apps, particularly in graphics-intensive applications or those that need considerable device hardware interaction.
  
  
• Platform-Specific Features: A common codebase may not give the same amount of access to platform-specific features and functionalities, resulting in a less optimal user experience.
  
  
• Framework Limitations: Relying on a cross-platform framework might limit your options since you are restricted by the framework's capabilities and limits.
  
  
• Update and Dependency Management: Frameworks for common codebases are often changed, making it difficult to keep your application compliant with the most recent versions.
  
  
• Complex Debugging: When bugs occur, they might be more difficult to track down and solve as they may originate in the cross-platform framework or be linked to how the same code interacts with multiple platforms.
  
  
• Customization Trade-offs: Achieving a native appearance and feel on each platform may necessitate additional customization, which could reverse some of the advantages of having a single codebase.
  
  
• Marketplace Compliance: Ensuring that the application fits the specifications of each app store might be more complex when working with a common codebase, as each platform has distinct rules and requirements.

What is a Separate Codebase?

A separate codebase is the practice of developing and maintaining separate sets of code for each platform that your application supports which means that instead of having one code that can be used on both web and mobile, you have several code repositories which are dedicated to each platform's native development environment.

What are the Benefits of Using Separate Codebases for Each Platform?

• Optimized Performance: Separate codebases allow for platform-specific improvements, ensuring that the application takes advantage of each device's capabilities, resulting in better performance.
  
  
• Tailored User Experience: Developers can develop user interfaces and interactions that follow each platform's regulations, creating a natural experience in the process.
  
  
• Full Feature Utilization: Applications that can use all APIs and tools of any platform can take the most out of the strengths and capabilities of any operating systems.
  
  
• Easier Debugging: When an issue emerges, debugging can be simplified since the code is platform-specific, making it easier to resolve issues.
  
  
• Independent Development Cycles: This codebase enables various development and release timelines for each platform, allowing the ability to roll out updates or fixes as needed.
  
  
• Specialized Expertise: Developers can focus on learning the unique features of a given platform, resulting in higher-quality code and awareness of platform-specific best practices.
  
  
• Scalability and Control: Each codebase can be created and maintained independently, providing developers more influence over the platform's resources and architecture. 
  
  
• No Framework Limitations: By eliminating dependency on cross-platform frameworks, developers are not restricted by the limits that those frameworks can have.
  
  
• Compliance with Platform Guidelines: When an application is built using a native codebase, it is easier to meet the specific requirements of each application store.

What are the Challenges of Separate Codebases for Different Platforms?

• Higher Costs: Maintaining several codebases requires many developers, which can raise labor and management costs.
  
  
• Development Redundancy: Features must be implemented various times across separate codebases, resulting in repetition of work and longer development timelines.
  
  
• Consistency Issues: When each platform has its own codebase, it can be challenging to ensure that all platforms deliver the same set of features and a consistent user experience.
  
  
• More Complex Project Management: Coordinating with various development teams and aligning release schedules across platforms can be challenging.
  
  
• Increased Testing Effort: Each codebase requires its own set of tests, increasing the total quality assurance effort and potentially slowing down the release process.
  
  
• Skillset Diversification: Separate codebases require developers that are proficient in several languages and frameworks, complicating recruitment and team composition.
  
  
• Longer Time to Market: The requirement to build, test, and deploy for different codebases frequently leads to longer development cycles and delays in delivering features to users.
  
  
• Maintenance Overhead: Each codebase must be individually maintained, updated, and secured, which adds to the overall effort.
  
  
• Platform-Specific Bugs: Bugs emerge on one platform must be addressed separately, which can result in inconsistent stability across your applications.
  
  
• Integration Complexity: Working with various back-end systems or APIs can be more difficult because each codebase may require different integration methodologies.
