Embracing Efficiency: How Symlink Support in 0.72 Can Transform Your Development Workflow

In the dynamic world of mobile app development, efficiency and streamlined workflows are key to fast delivery and high-quality products. React Native's introduction of symlink support in version 0.72 has been a game-changer, particularly for developers utilizing monorepo setups. This feature simplifies the process of managing and linking packages, enhancing productivity and reducing complexity. As a Chief Technology Officer (CTO) or a development lead, understanding and leveraging the power of symlink support can significantly transform your team's workflow, leading to more efficient and organized codebases.

Understanding Symlink Support

A symlink, or symbolic link, is essentially a pointer or shortcut to another file or directory. In the context of software development, symlinks allow you to access and reference files or directories from multiple locations without duplicating them. This is especially useful in monorepos, where multiple projects might share common libraries or components.

React Native 0.72 introduced support for resolving symlinks in Metro, its JavaScript bundler. This means that developers can now use symlinks to structure their projects more efficiently, reusing code and resources across their applications without the hassle of manual copying or complex configurations.

The Benefits of Symlink Support

  1. Simplified Project Management: Symlink support makes it easier to manage dependencies and shared code in a monorepo setup, reducing the need for repetitive configurations and manual copying of files.

  2. Improved Code Reusability: By linking to shared libraries or components, you can reuse code across multiple projects within a monorepo, ensuring consistency and reducing the potential for errors.

  3. Faster Development Cycles: With easier access to shared resources and reduced setup time, developers can focus more on coding and less on managing project structure, leading to faster development cycles.

  4. Enhanced Collaboration: Symlink support fosters a more collaborative environment by allowing teams to work on shared codebases efficiently, making it easier to contribute to and maintain common libraries or components.

Implementing Symlink Support in Your Projects

To leverage symlink support in React Native 0.72, you'll need to enable the unstable_enableSymlinks option in your Metro configuration. This tells Metro to follow symlinks when resolving modules, allowing you to structure your project using symbolic links.

While enabling symlink support is relatively straightforward, it's essential to plan and structure your project carefully. Consider the dependencies and relationships between various parts of your codebase, and use symlinks strategically to maximize efficiency and maintainability.

Best Practices for Using Symlink Support

  1. Clearly Document Your Structure: Ensure that your project's structure and the use of symlinks are well-documented, making it easier for new team members to understand and navigate the codebase.

  2. Test Thoroughly: Test your setup thoroughly to ensure that all linked resources are resolving correctly and that there are no issues with your build process.

  3. Monitor Performance: Keep an eye on your app's performance to ensure that the use of symlinks isn't introducing any unexpected issues or bottlenecks.

  4. Stay Updated: Keep your React Native and Metro versions up to date to benefit from ongoing improvements and fixes related to symlink support.


Embracing symlink support in React Native 0.72 can significantly transform your development workflow, making it more efficient, organized, and collaborative. By understanding and leveraging this feature, you can streamline your project management, improve code reusability, and accelerate your development cycles. As a CTO or development lead, taking the time to implement and optimize symlink support in your projects is a strategic investment that can yield substantial benefits for your team and your products.
