Exclude Peer Dependencies From Size Calculation

Understanding Bundle Size Calculation

When it comes to measuring the size of a bundle, there are various factors to consider. One crucial aspect is the inclusion of peer dependencies in the size calculation. Peer dependencies are packages that are not required by the main project but are necessary for its functionality. In this article, we will explore the concept of excluding peer dependencies from size calculation and its implications.

The Problem with Peer Dependencies

Peer dependencies can significantly impact the size of a bundle. As seen in the example of the knip tool, a peer dependency like typescript can account for a substantial portion of the bundle size. This can be problematic for repository owners who have no control over the peer dependencies used by their dependencies. In such cases, it becomes challenging to identify and address large bundle sizes.

The Need for Exclusion

Given the issue with peer dependencies, there is a growing need to exclude them from size calculation. This would enable repository owners to focus on optimizing the size of their own dependencies, rather than being influenced by peer dependencies. Excluding peer dependencies from size calculation would also provide a more accurate representation of the bundle size, making it easier to identify areas for improvement.

Current Solutions

Currently, there are no built-in options to exclude peer dependencies from size calculation. However, some tools and libraries offer workarounds to address this issue. For instance, some tools allow users to specify custom dependencies to include or exclude from size calculation. While these workarounds can be helpful, they may not be comprehensive or user-friendly.

Proposed Solution

To address the issue of peer dependencies in size calculation, we propose the following solution:

  • Option to exclude peer dependencies: Provide an option to exclude peer dependencies from size calculation. This would enable users to focus on optimizing the size of their own dependencies.
  • Default exclusion: Consider excluding peer dependencies by default. This would ensure that users are not influenced by peer dependencies and can focus on optimizing their own dependencies.

Benefits of Exclusion

Excluding peer dependencies from size calculation would have several benefits, including:

  • Improved accuracy: Excluding peer dependencies would provide a more accurate representation of the bundle size, making it easier to identify areas for improvement.
  • Increased control: By excluding peer dependencies, users would have more control over the size of their bundle, enabling them to focus on optimizing their own dependencies.
  • Simplified optimization: Excluding peer dependencies would simplify the optimization process, as users would not need to worry about the impact of peer dependencies on their bundle size.

Implementation

To implement the proposed solution, we would need to modify the underlying algorithms and data structures used for size calculation. This would involve:

  • Identifying peer dependencies: Develop a mechanism to identify peer dependencies in the project's dependency graph.
  • Excluding peer dependencies: Modify the size calculation algorithm to exclude peer dependencies from the calculation.
  • Providing options: Offer users the option to include or exclude peer dependencies from size calculation.

Conclusion

Excluding peer dependencies from size calculation is a crucial step towards providing a more accurate representation of bundle size. By offering users the option to exclude peer dependencies, we can simplify the optimization process and enable users to focus on optimizing their own dependencies. While there are no built-in options to exclude peer dependencies currently, we propose a solution that would provide users with more control over their bundle size.

Future Work

To further improve the solution, we would need to:

  • Develop a more comprehensive solution: Develop a more comprehensive solution that addresses the issue of peer dependencies in size calculation.
  • Improve user experience: Improve the user experience by providing a more intuitive and user-friendly interface for excluding peer dependencies.
  • Integrate with existing tools: Integrate the proposed solution with existing tools and libraries to ensure seamless integration and compatibility.
