How do I exclude dependencies from my Bun bundle?

You can use the 'external' configuration property in the build API or CLI to mark specific packages that should not be included in the final output.

What targets does Bun Bundler support?

Bun can bundle code for browser, Node.js, and the native Bun runtime using the --target flag or the programmatic API configuration.

Can I create custom plugins for the Bun build process?

Yes, this skill provides patterns for implementing the BunPlugin interface to handle custom file types, loaders, and build lifecycle hooks.

Can I use Bun Bundler for code splitting?
