feat(mail): add clean email content copy button - Add copy button to …

[R44VC0RP]

Description

Added a new feature to copy email content cleanly from the email display. This adds a copy button next to the AI summary button that extracts only the relevant text content from HTML emails, removing any CSS, template code, or invisible characters. The feature includes visual feedback (checkmark icon) when copying is successful and preserves email metadata like subject and sender information in the copied text.

This feature was implemented with AI assistance (Claude). The code has been carefully reviewed and tested to ensure:

• Proper HTML sanitization using DOMPurify
• Clean text extraction without template/styling code
• Proper handling of email metadata
• Accessibility and UX best practices
• Type safety with TypeScript

Walkthrough

This change integrates a clipboard copy feature into the mail display component. A new function, copyEmailContent, sanitizes the email content using DOMPurify and formats it with subject and sender details before copying. An accompanying state variable, isCopied, manages the visual feedback on success. Additionally, the rendering logic for the cc field is refined to ensure correct conditional display.

Poem

I hopped through lines of code so neat,
Adding a copy feature as a sweet treat,
With DOMPurify cleaning the HTML mess,
"isCopied" shines when the copy is a success,
From a rabbit’s burrow, these changes do gleam,
A playful nibble on code, like a dream.

🪧 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.
