A compact JavaScript SDK for HTTP packet capture, traffic inspection, and replay workflows.

Features

• Request/response capture pipeline with lifecycle hooks.
• Header and payload sanitization before persistence.
• Session-based trace grouping for multi-step flows.
• Export support for JSONL and HAR-like snapshots.
• Optional replay mode for deterministic debugging.

Quick Example

import { execAlpha } from '@dustticket/kit'

const traces = await execAlpha({
  ticketUrl: 'https://api.example.com/v1/orders',
  type: 'http',
})

if (!traces) {
  // capture pipeline unavailable
}
