SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Audit Terrae components for performance bottlenecks and memory leaks, delivering actionable fixes to improve UI responsiveness and stability.

Core Features & Use Cases

Comprehensive audits: scans components for common performance pitfalls and reports prioritized fixes.
Structured reports: outputs a clear score, critical issues, warnings, and best practices.
Use Case: optimize a slow map component by identifying expensive renders and refactors.

Quick Start

Identify a target component with ARGUMENTS or audit all components to generate a performance report.

FAQPage Schema

How do I audit React components for memory leaks and performance issues?▼

Mapbox objects in React state cause performance issues because they trigger expensive re-renders, whereas storing them in refs prevents unnecessary render cycles and improves UI responsiveness.

What is the best way to optimize GeoJSON handling and layer management in map components?▼

Optimizing GeoJSON handling and layer management in map components requires auditing source management and DOM manipulation to identify bottlenecks and apply actionable refactoring fixes.

Can I scan my entire codebase for React performance bottlenecks or do I need to specify a target?▼

You can scan your entire codebase for React performance bottlenecks without specifying a target, or you can scope the audit specifically to components within the src/registry/map/ directory.

Why does my map component have slow canvas performance and expensive renders?▼

Slow canvas performance and expensive renders in map components often stem from improper resource cleanup, unmanaged timers, or inefficient GeoJSON handling, which a structured audit can identify and fix.
