Walkthrough

The changes update the email draft creation and display logic in a mail application. The draft creation process now builds a MIME multipart message with proper boundaries and headers, supporting attachments and structured formatting. The draft editor component adjusts its state management and error handling when loading and saving drafts, including more robust parsing and stricter save conditions. The draft list component refines how recipient information is displayed, introducing a new prop type and improved logic for showing recipient names or indicating when no recipient is present.

Changes

File(s)	Change Summary
apps/mail/app/api/driver/google.ts	Updated the createDraft method to construct a MIME multipart message with boundaries, headers, and support for attachments. Improved encoding and message assembly. No changes to exported/public entities.
apps/mail/components/create/create-email.tsx	Modified draft loading to defer JSON parsing for editor reset, improved error handling, and set empty content on failure. Tightened draft saving guard to require all fields, and now includes cc and bcc in the saved draft data. No changes to exported/public entities.
apps/mail/components/draft/drafts-list.tsx	Refined the Draft component's props by introducing DraftProps, updated recipient display logic to show "No recipient" when appropriate, and formatted recipient names/emails. Updated component signature.

Poem

In the warren where messages hop and bound,
MIME parts and headers are skillfully found.
Recipients now shine or are gently concealed,
While drafts are more safely and smartly revealed.
Attachments and CCs, all tucked in with care—
This rabbit’s mail magic is floating on air!

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
