FAQPage Schema

How do I find and remove unused dependencies in a Node.js project?▼

To remove unused dependencies in a Node.js project, you can run a static analysis tool to generate a cleanup report identifying unused files, dependencies, and exports for safe pruning.

What is dead code and how does it affect codebase maintenance?▼

Dead code refers to unused files, exports, and dependencies that add bloat and increase maintenance effort. Identifying and removing them streamlines the project and reduces ongoing technical overhead.

Can I safely prune dead exports during a large refactoring project?▼

Yes, you can safely prune dead exports during refactoring by using static analysis to suggest impact-safe removals, though you should verify the cleanup report before finalizing deletions.

Do I need a specific environment to run unused file and dependency cleanup?▼

You need a local Node.js environment with npm or yarn installed, along with a configuration file to drive the rules for safe cleanup and dependency pruning across your repositories.

What's the best way to automate dependency pruning across repositories?▼

Automating dependency pruning across repositories involves running configured static analysis commands against your projects to detect unused packages and dead code, generating reports for streamlined maintenance.
