committed, which leaks developer environment details (username and directory structure)
and may unintentionally expose sensitive local information in the repository history.

Status:
Missing null guards: Query-derived leaderboard fields (e.g., user.language, user.topLanguage, user.streak,
user.score) are assumed to always be present/non-null based solely on local types without
explicit runtime guarding if the backend can return null/undefined.

  ? streakData.map((user: StreakEntry, index: number) => {
      const rank = offset + index + 1;
      return (

Objective: Ensure all data inputs are validated, sanitized, and handled securely to prevent
vulnerabilities

Status:
Unvalidated query data: UI rendering uses query-provided values like displayName and numeric fields without
validating/normalizing the backend payload shape at runtime, which may be unsafe if the
API can return unexpected/null values.

      <MiniLeaderboardRow
        key={`${user.displayName}-${user.rank}`}

To improve maintainability, consolidate the duplicated StreakEntry and
ProgressEntry types into a shared location. Normalize streakData and
progressData into a unified structure to simplify rendering with a single .map()
call, removing conditional logic.

Examples:

              {isStreak
                ? streakData.map((user: StreakEntry, index: number) => {
                    const rank = offset + index + 1;
                    return (
                      <LeaderboardRow
                        key={`${user.displayName}-${rank}`}
                        rank={rank}
                        displayName={user.displayName}
                        medal={getMedalIcon(rank)}
                        isUser={isCurrentUser(rank)}

Solution Walkthrough:

Before:

// In LeaderboardPage component
type StreakEntry = { ... };
type ProgressEntry = { ... };
const isStreak = selectedType === "streak";

// ...
{isStreak
  ? streakData.map((user: StreakEntry) => (
      <LeaderboardRow
        language={getLanguageFlagString(user.language)}
        value={`${user.streak} days`}
        ...
      />
    ))
  : progressData.map((user: ProgressEntry) => (
      <LeaderboardRow
        language={getLanguageFlagString(user.topLanguage)}
        value={`${Math.round(user.score)} pts`}
        ...
      />
    ))
}

After:

// In a shared types file
type NormalizedEntry = { displayName: string; language: string; value: string; ... };

// In LeaderboardPage component
const normalizedData: NormalizedEntry[] = useMemo(() => {
  if (isStreak) {
    return streakData.map(u => ({ ...u, value: `${u.streak} days` }));
  }
  return progressData.map(u => ({ ...u, language: u.topLanguage, value: `${Math.round(u.score)} pts` }));
}, [isStreak, streakData, progressData]);

// ...
{normalizedData.map((user: NormalizedEntry) => (
  <LeaderboardRow
    language={getLanguageFlagString(user.language)}
    value={user.value}
    ...
  />
))}

Remove the committed node_modules file and add node_modules/ to the .gitignore
file to properly ignore the directory.

Add nullish coalescing fallbacks (?? 0) to user.streak and user.score to prevent
potential runtime errors if the values are null or undefined.

-value={`${user.streak} days`}
+value={`${user.streak ?? 0} days`}
 ...
-value={`${Math.round(user.score)} pts`}
+value={`${Math.round(user.score ?? 0)} pts`}

Extract the inline props of the LeaderboardRow component into a dedicated
LeaderboardRowProps type for better readability and reusability.

src/routes/_authed/leaderboard.tsx [21-28]

-function LeaderboardRow({ rank, displayName, medal, isUser, language, value }: {
+type LeaderboardRowProps = {
   rank: number;
   displayName: string;
   medal: string | null;
   isUser: boolean;
   language: string;
   value: string;
-}) {
+};
 
+function LeaderboardRow({ rank, displayName, medal, isUser, language, value }: LeaderboardRowProps) {

Remove the redundant boolean cast (!!) from the isCurrentUser prop calculation,
as the expression already evaluates to a boolean.

-isCurrentUser={!!(hasDisplayName && userRank && user.rank === userRank.rank)}
+isCurrentUser={hasDisplayName && userRank && user.rank === userRank.rank}
