📝 Walkthrough

Walkthrough

When nitro.options.cloudflare.nodeCompat is enabled, enableNodeCompat now ensures nitro.options.rolldownConfig exists and sets its platform to "node" (if unset) before adding the unenvCfNodeCompat entry to nitro.options.unenv.

Changes

Cohort / File(s)	Summary
Cloudflare Node Compatibility Configuration src/presets/cloudflare/utils.ts	When nodeCompat is truthy, initialize nitro.options.rolldownConfig (default {}) and set rolldownConfig.platform = "node" if not already set, then add unenvCfNodeCompat to nitro.options.unenv.
