Implements Cloudflare Workers target with export conditions matching Wrangler's behavior: - workerd (first priority - Cloudflare's runtime) - worker (second priority - generic web worker) - browser (third priority - browser-compatible code) This matches the official Wrangler bundler behavior as documented in: https://github.com/cloudflare/workers-sdk/blob/main/packages/wrangler/src/deployment-bundle/bundle.ts#L51-L88 Like node and bun targets, cloudflare is a server-side target that: - Uses isServerSide() = true - Prefers module field over main in package.json - Uses .esm output format (not .esm_ascii like bun target) Changes: - Added cloudflare to options.Target enum - Added cloudflare to Api.Target enum - Configured default export conditions for cloudflare target (workerd, worker, browser) - Updated all switch statements to handle cloudflare case - Refactored CLI argument parser to use ComptimeStringMap instead of ExactSizeMatcher - Added comprehensive test suite in test/bundler/bundler_cloudflare.test.ts Tests verify: - workerd condition has highest priority - Falls back to worker then browser conditions - Falls back to default when no cloudflare-related conditions match - Handles nested exports with conditions - Works with multiple packages using different conditions - Prefers module field like other server-side targets 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
