Walkthrough

The pull request introduces significant refactoring in the Roam application's page reference handling. The changes primarily focus on modularizing the code by extracting page reference observer handlers into a separate utility module. This involves moving functions like overlayPageRefHandler and previewPageRefHandler from the main module to a new pageRefObserverHandlers.ts file. Additionally, new utility functions for checking page types (isCurrentPageCanvas and isDiscourseNodeConfigPage) have been added to improve type checking and page identification.

Changes

File	Change Summary
apps/roam/src/discourseGraphsMode.ts	Removed inline page reference handlers, now importing from new utility module
apps/roam/src/index.ts	Updated imports, modified page type checking logic, enhanced observer registration
apps/roam/src/utils/isCanvasPage.ts	Added isCurrentPageCanvas function for enhanced canvas page detection

🐰 Hop, hop, through the code we go,
Refactoring pages with a rabbit's glow
Observers dancing, handlers so neat
Modularity makes our codebase sweet!
A cleaner path, our changes unfold 🌟

🪧 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.
