Performance Profiling

Zintrust includes built-in profiling tools to help you identify and resolve performance bottlenecks.

Request Profiling

The RequestProfiler tracks the execution time of every request, including time spent in middleware and controllers.

// In your controller
const profile = req.profiler.start('expensive-operation');
await doSomething();
profile.end();

Memory Profiling

Use the MemoryProfiler to track memory usage and identify potential leaks.

import { MemoryProfiler } from '@performance/MemoryProfiler';

const stats = MemoryProfiler.getStats();
console.log(`Heap used: ${stats.heapUsed} MB`);

N+1 Query Detection

Zintrust automatically detects N+1 query patterns in development mode and logs a warning to the console.

[N1Detector] Warning: Potential N+1 query detected on table 'posts'.

Real-time Dashboard

The zin debug command provides a real-time terminal dashboard showing:

• CPU and Memory usage.
• Active HTTP requests.
• Database query performance.
• Service health status.
