Reduce frontend dependencies before they become a maintenance problem.
A dependency should only remain if its ongoing benefits justify the integration, update, and security overhead compared to native solutions.
For frontend developers and web designers, when it comes to "targeted reduction of frontend dependencies," "actual functionality" and "maintainability" are crucial. The perspective "Design system and component boundaries" shows how these two points interact in practice.

What criteria should a team use to decide whether to retain or remove frontend dependencies?
Each library is evaluated against its actual functionality and the overall maintenance effort. Small functions are moved to platform APIs or local code if this clarifies testing and responsibility.
Delimitation Case: “Transitive Last”
A library is used only to open a simple dialog, but it includes its own state and styling logic. The team encapsulates the call, replaces it with the existing platform function, and checks focus handling and older target browsers before removal.
Transitive Last
Transitive Last – A small direct dependency results in numerous packages and update paths.
Orphaned package – Critical functions depend on unmaintained code whose bugs and security vulnerabilities are not reliably fixed.
Blind replacement – Removing the code overlooks rare browser or accessibility issues.
Significant functional impact
Test criterion
Significant functional impact
The application uses a substantial, difficult-to-replace part of the library.
Test criterion
Maintainability
Updates, security alerts, and compatibility have a reliable path.
Exchange boundary A local interface prevents library details from permeating the entire frontend.
Exchange boundary
Outdated frontend packages with a production code path.
Loaded and executed bytes per dependency on representative routes.
Maintainability
Direct and transitive packages are inventoried with regard to usage, size, maintenance, and affected components.
Candidates are encapsulated and compared against native or local alternatives using the same test cases.
Exchange is performed package by package with measurement, regression testing, and documented return paths.

If you want to practically implement "Targeted Reduction of Frontend Dependencies," you can refer to Robust Website Systems This focuses on "Design System and Component Boundaries" and "Actual Functionality."
Conclusion: Targeted Reduction of Frontend Dependencies
Fewer dependencies are only better if functionality and testability are maintained. A clear exchange boundary reduces risk in both areas.
Sources and Further Information
These primary sources make assumptions, system boundaries, and testing methods for "Targeted Reduction of Frontend Dependencies" comprehensible.
Baseline – web.devThe model maintained by the Web Platform Initiative makes the cross-browser availability of platform functions verifiable.
CSS Custom Properties for Cascading Variables Level 1 – W3CThis specification provides the binding basis for inherited, replaced, and fallbacked CSS variables.
Key Thesis
The usage, bundle share, maintenance status, and replacement costs of each library are inventoried. Small or critical functions are moved to platform APIs or local code if this clarifies responsibility and testing.
What This Is Not About
Dependencies are neither inherently bad nor justifiable in the long term simply because of a small bundle.
What it's about
Utility, runtime costs, maintenance status, security approach, and replaceability determine whether to retain, encapsulate, or remove dependencies.
