Description

  • The lineProps property on Highlight component exported styles with className property using tailwind css which for some reason react-sytax-highlight library was not able to recognize.

Walkthrough

The changes modify the CodeBlock component in components/editor/CodeBlock.tsx, focusing on the visual representation of highlighted lines. The update introduces a new approach to styling line numbers and highlighted lines, changing background and text colors. The lineProps function has been refactored to create a more dynamic style object that conditionally applies highlighting based on the line's status.

🐰 Code blocks dancing with light,
Lines highlighted, oh so bright!
From dark to blue, a subtle gleam,
Revealing secrets of our coding dream.
A rabbit's touch of style so neat! 🖥️

278-286: LGTM! Consider adding type annotation for better maintainability.

The refactored lineNumberStyle implementation looks good with improved color contrast and explicit spacing.

Consider adding a type annotation for better maintainability:

-              const styles = {
+              const styles: React.CSSProperties = {

292-303: LGTM! Consider performance optimization.

The switch from Tailwind classes to explicit styles successfully fixes the highlighting issue. However, consider memoizing the styles to avoid creating new objects for each line.

Consider this optimization:

+ const baseStyle: React.CSSProperties = { paddingRight: '2rem' };
+ const highlightedStyle: React.CSSProperties = {
+   ...baseStyle,
+   display: 'block',
+   width: '100%',
+   backgroundColor: '#3e4d64'
+ };

  lineProps={(lineNumber: number) => ({
-   style: {
-     paddingRight: '2rem',
-     ...(isHighlighted && {
-       display: 'block',
-       width: '100%',
-       backgroundColor: '#3e4d64'
-     })
-   }
+   style: isHighlighted ? highlightedStyle : baseStyle
  })}

Technically looks fixed: https://deploy-preview-3480--asyncapi-website.netlify.app/docs/tutorials/getting-started/servers

but I do not own code here for quite some time, so not reviewing if applied approach was correct
