How does it handle environment-specific configurations?

The skill demonstrates how to use global constant replacement (define) to inject environment variables like API URLs or NODE_ENV at build time.

Can I use this for complex library development?

Absolutely. It includes patterns for building libraries with multiple output formats like ESM and CJS, along with proper external dependency management.

What build targets does the Bun Bundler skill support?

The skill provides guidance for targeting the Bun runtime, web browsers, and Node.js environments, ensuring your code runs correctly wherever it is deployed.

Does this skill help with reducing bundle size?

Yes, it covers advanced tree-shaking techniques and code splitting strategies to ensure only the necessary code is delivered to your users.
