Vue Tabs / Multi-View Switcher

What you’ll build / What this tests

This premium vue coding focuses on Vue Tabs / Multi-View Switcher. You’ll apply vue and components thinking with easy level constraints. The prompt emphasizes Implement Vue 3 tabs using a single activeTab state. Buttons update the active tab, and conditional….

Learning goals

• Translate the prompt into a clear vue API signature and return shape.
• Apply vue, components, reactivity techniques to implement vue tabs / multi-view switcher.
• Handle easy edge cases without sacrificing readability.
• Reason about time/space complexity and trade-offs in vue.

Key decisions to discuss

• Define the exact input/output contract before coding.
• Prioritize predictable edge-case handling over micro-optimizations.

Evaluation rubric

• Correctness: covers required behaviors and edge cases.
• Clarity: readable structure and predictable control flow.
• Complexity: avoids unnecessary work for large inputs.
• API discipline: no mutation of inputs; returns expected shape.
• Testability: solution is easy to unit test.

Constraints / Requirements

• Render a tabbed UI with three tabs labeled "Overview", "Details", and "Settings".
• Track which tab is currently active and visually highlight it.
• Render only the active tab's content at a time.
• The initial active tab should be "Overview".
• Clicking a tab makes it the active tab.
• Only the active tab's panel is visible at any time.
• The active tab button has a distinct visual style (e.g., filled pill) compared to inactive ones.
• Use Vue 3's Composition API with ref to store the currently active tab.
• Model the tab id as a string union (e.g., 'overview' | 'details' | 'settings').
• Use a helper function like isActive(tab) to drive both active styles and conditional rendering.

Mini snippet (usage only)

// Example usage
const input = /* vue tabs / multi-view switcher input */;
const result = solve(input);
console.log(result);

// Edge case check
const empty = input ?? null;
const fallback = solve(input);
console.log(fallback);

// Expected: describe output shape, not the implementation
// (no solution code in preview)

Common pitfalls

• Mutating inputs instead of returning a new value.
• Skipping edge cases like empty input, duplicates, or nulls.
• Overlooking time complexity for large inputs.
