Question 1

How to set up eslint-plugin-boundaries for a monorepo?

Accepted Answer

Define element patterns that match your monorepo structure, such as per-package directories, and configure dependency rules to control cross-package imports. The flexible configuration supports glob patterns for this.

Question 2

eslint-plugin-boundaries vs dependency-cruiser: which should I use?

Accepted Answer

eslint-plugin-boundaries integrates into ESLint for real-time feedback during development, while dependency-cruiser is a standalone tool for comprehensive dependency analysis. Use boundaries for enforcements in your workflow and cruiser for audits or deeper insights.

Question 3

Does it work with dynamic imports in JavaScript?

Accepted Answer

No, the plugin only analyzes static import statements, so dynamic imports won't be caught by the boundary checks. You'll need manual reviews or other tools for runtime dependency validation.

Question 4

How to define custom architectural layers with this plugin?

Accepted Answer

In your ESLint configuration, specify elements with types and patterns (e.g., 'service' for 'services/*'), then create rules to define allowed dependencies between these types, as detailed in the setup guide.

Question 5

What's the performance impact on linting speed?

Accepted Answer

It adds minimal overhead during ESLint runs, but complex rules or large codebases with many elements might slow down linting slightly. Optimize by using efficient element selectors.

Question 6

Can I use it to prevent circular dependencies?

Accepted Answer

Yes, by configuring dependency rules that disallow bidirectional imports between elements, you can enforce acyclic dependencies, though it requires careful rule definition to match your architecture.
