# ⛓️‍💥 RAVEN: Request Archive for Virtual Endpoint Navigation

> **"Impeccable imitation, seamless navigation."**

**RAVEN** is a high-performance network virtualization engine designed to record, archive, and replay API traffic directly at the browser's network layer. Inspired by the shapeshifter **Raven Darkhölme**, this tool acts as a transparent proxy, allowing your application to "morph" its environment by mimicking real backend responses from a local vault.

## 🚀 Overview

**RAVEN** solves the "unstable infrastructure" problem by decoupling your front-end from the back-end. Unlike traditional mocking tools, RAVEN operates via **Service Workers**, intercepting every network request (XHR/Fetch) before it even leaves the browser. This enables offline demos, stress-free development, and high-fidelity showcases with zero interference in the main thread.

## ✨ Core Features

* **🔴 Record Mode**: Automatically captures every network interaction and persists it in a structured IndexedDB vault.
* **▶️ Replay Mode**: Provides instant, zero-latency responses from the archive. No internet required.
* **🛡️ Native Interception**: Powered by Service Workers for a non-destructive approach. No prototype overrides—just pure, low-level network redirection.
* **📦 Showcase Engine**: Import pre-defined "Journey" files (JSON) to deploy guided, interactive product walkthroughs.
* **⚡ Zero-Latency Dev**: Stop waiting for slow database queries or 3rd-party services during front-end iterations.

## 🛠 Target Audience

### 🎤 For Sales & Solutions Architects
Deliver flawless demos. Eliminate risks associated with server downtime, database lag, or poor conference Wi-Fi. Your app remains fast and predictable, every single time.

### 👩‍💻 For Front-end Developers
Develop in isolation. Work on UI components even when the API is down or unfinished. Prevent "development fatigue" caused by constant page refreshes and slow network roundtrips.

### 📚 For Product & Marketing
Create "Golden Path" catalogs. Ship interactive examples of your platform using real data snapshots that users can explore without needing a live staging account.

## 🏗 How It Works

RAVEN acts as a **Programmable Proxy** sitting between your application and the internet.



1.  **Interception**: The RAVEN Service Worker listens to the `fetch` event, catching all outgoing `XMLHttpRequest` and `fetch()` calls.
2.  **Archiving**: In *Record Mode*, responses are cloned and stored in **IndexedDB** along with their metadata (headers, status, URL).
3.  **Navigation**: In *Replay Mode*, the Service Worker bypasses the network entirely, matching the request against the archive and serving the stored response.

## 📂 Data Vault (IndexedDB)

RAVEN organizes your virtual environment through a structured hierarchy:

* 📁 **Sessions**: High-level scenarios (e.g., "Full Purchase Flow").
* 📍 **Routes**: Normalized URL patterns grouped within a session.
* ⚡ **Requests**: The actual archived payloads (method, status, response body).

## ⌨️ Quick Start

### 1. Installation
Register the RAVEN Service Worker in your application's entry point:

```javascript
if ('serviceWorker' in navigator) {
    navigator.serviceWorker.register('/raven-sw.js');
}
