Greptile Overview

Greptile Summary

Removes 5 MDX-related packages (next-mdx-remote, gray-matter, rehype-autolink-headings, rehype-slug, remark-gfm) from the transpilePackages array in Next.js configuration.

Key Points:

• These packages were accidentally added in PR #1698 (platform-v3)
• The packages are actively used by the blog system in lib/blog/registry.ts and lib/blog/mdx.tsx
• They import from /rsc subpath (React Server Components), which are already properly formatted for Next.js App Router
• The transpilePackages option is only needed for packages that contain client-side code with incompatible module formats
• This fix reduces unnecessary build-time transpilation overhead

Confidence Score: 5/5

• This PR is safe to merge with no risk
• The change correctly removes packages that don't require transpilation. The MDX packages use React Server Components exports (/rsc) which are already compatible with Next.js App Router. The packages remain installed as dependencies and continue to be used by the blog system, so no functionality is affected. This simply optimizes the build configuration by removing unnecessary transpilation steps.
• No files require special attention
