Walkthrough

The pull request introduces an asynchronous disposal mechanism for the BitPdfReader component across multiple files. The changes involve implementing the IAsyncDisposable interface in the C# component, adding a new dispose method in the TypeScript implementation, and extending the JavaScript runtime extensions with a new disposal method. These modifications enable proper resource cleanup for PDF reader instances, ensuring efficient memory management and preventing potential resource leaks.

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.

src/BlazorUI/Bit.BlazorUI.Extras/Components/PdfReader/BitPdfReader.ts (1)

106-112: Add error handling and canvas cleanup to dispose.

While the basic disposal logic is correct, consider these improvements:

1. Add try-catch around pdfDoc.destroy() to handle potential errors
2. Clean up canvas elements to prevent memory leaks

 public static dispose(id: string) {
     const config = PdfReader._bitPdfReaders.get(id);
     if (!config) return;

-    config.pdfDoc?.destroy();
+    try {
+        config.pdfDoc?.destroy();
+        // Clean up canvas elements
+        const canvas = document.getElementById(config.id);
+        canvas?.remove();
+    } catch (error) {
+        console.error(`Error disposing PDF reader ${id}:`, error);
+    }
     PdfReader._bitPdfReaders.delete(id);
 }

src/BlazorUI/Bit.BlazorUI.Extras/Components/PdfReader/BitPdfReader.razor.cs (2)

8-8: Consider implementing the full disposable pattern.

The class implements IAsyncDisposable but should follow the complete disposable pattern to ensure proper cleanup in all scenarios.

-public partial class BitPdfReader : IAsyncDisposable
+public partial class BitPdfReader : IAsyncDisposable, IDisposable

---

39-39: Consider making Config initialization thread-safe.

The current default initialization might not be thread-safe in all scenarios.

-[Parameter] public BitPdfReaderConfig Config { get; set; } = new();
+[Parameter] public BitPdfReaderConfig Config { get; set; } = new BitPdfReaderConfig();
