Walkthrough

The PageHelper class in src/common/helper/page.helper.ts has been significantly enhanced to improve documentation and method signatures for pagination functionality. These updates include clearer method descriptions, detailed parameter information, and SQL equivalents for various pagination scenarios, making the class more user-friendly and maintainable.

Changes

File Path	Change Summary
src/common/helper/page.helper.ts	Updated PageStart method description and parameters. Added PageMiddle method. Improved PageFromAll method clarity and parameters. Added PageInternal private method with detailed descriptions.

In code's vast field, a helper stands tall,
To paginate wisely, to answer the call.
From start to middle, and all records found,
It guides through the pages, with logic profound.
A rabbit's delight in each line and clause,
Hopping through code, without a pause. 🐇

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>.
  • 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 generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @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.

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.

13-28: Excellent documentation for PageStart.

The detailed comments and SQL equivalent provide clear understanding of the method's functionality. This is a great example of how to document methods for better clarity and maintainability.

---

37-61: Well-documented and implemented PageMiddle method.

The method handles pagination from a middle position effectively. The documentation is thorough, including SQL equivalents for both previous and current page data fetching. This clarity in documentation helps in understanding the complex logic involved.

---

85-100: Review the error handling in PageFromAll.

The method PageFromAll includes an optional error handler which is a good practice. However, ensure that the error handling is tested thoroughly, especially the scenario where pageStart is not found in allData.
