    • 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.

🧹 Nitpick comments (3)
packages/react/components/price/PriceHelpers.ts (1)

1-2: LGTM! Clean and concise implementation.

The simplified ternary operation makes the code more readable while maintaining the same functionality.

Consider adding:

  1. Input validation to ensure text contains only digits
  2. JSDoc documentation explaining the function's purpose
+/**
+ * Ensures cents are displayed with 2 digits by padding with a trailing zero if needed.
+ * @param text - The cents portion of a price (e.g., "5" or "50")
+ * @returns The padded cents string (e.g., "50" or "50")
+ * @throws {Error} If text contains non-digit characters
+ */
 export const checkCents = (text: string): string => {
+  if (!/^\d+$/.test(text)) {
+    throw new Error('Input must contain only digits');
+  }
   return text.length === 1 ? `${text}0` : text
 }
packages/react/components/price/Price.tsx (2)

56-69: Fix typo and consider performance optimization.

  1. The function name has a typo: getAmoutContent should be getAmountContent
  2. Consider memoizing this function since it creates JSX elements that could be reused across renders.
-  const getAmoutContent = (amount: number, cents: string) => {
+  const getAmountContent = React.useMemo(
+    () => (amount: number, cents: string) => {
       return (
         <>
           <Text markup={TextMarkup.SPAN}>{amount}</Text>
           <span className={hashClass(styled, clsx('price-details'))}>
             <span className={hashClass(styled, clsx('cents'))}>
               &nbsp;€{hideCents ? '' : cents}
               {mention && <sup>{mention}</sup>}
             </span>
             {period && <span className={hashClass(styled, clsx('period'))}>/{period}</span>}
           </span>
         </>
       )
+    },
+    [hideCents, mention, period, styled]
+  )

Line range hint 102-106: Simplify alignment class logic.

The alignment class logic could be simplified using an object mapping or switch statement for better readability.

+  const alignmentClasses = {
+    [Alignable.ALIGNED_START]: 'justified-left',
+    [Alignable.ALIGNED_CENTER]: 'justified-center',
+    [Alignable.ALIGNED_END]: 'justified-right',
+  }

   <div
     id={id}
     className={hashClass(
       styled,
       clsx(
         'price-container',
         is(`level-${level}`),
-        (align == Alignable.ALIGNED_START && is('justified-left')) ||
-          (align == Alignable.ALIGNED_CENTER && is('justified-center')) ||
-          (align == Alignable.ALIGNED_END && is('justified-right')) ||
-          '',
+        align && is(alignmentClasses[align] || ''),
       ),
     )}

36-36: LGTM! Good default prop value addition.

Adding a default value for the level prop is a good practice for backward compatibility and makes the prop optional.

💡 Codebase verification

Remove redundant aria-label attribute

The component has redundant accessibility attributes. The aria-hidden="true" span should not have an aria-label since it's explicitly hidden from screen readers. The accessibility is already properly handled by the sr-only paragraph element.

  • Remove the aria-label attribute from line 89:
<span aria-hidden='true' className={classes} {...others}>
🔗 Analysis chain

Verify aria-label implementation.

The component uses both aria-label and a separate element with sr-only class for the same content. This might be redundant.

Also applies to: 113-113
