How logget Works

This document explains how logget works from a conceptual perspective, helping you understand what happens when you use it.

What is logget?

logget is a command-line tool that opens a web page in an invisible browser and captures everything that happens: network requests, console messages, and JavaScript errors. Think of it as a spy or observer that watches what a website does behind the scenes.

The Big Picture

Two Ways to Use logget

Normal Mode - One-Time Capture

In normal mode, logget loads the page once, captures everything that happens, and then shows you the results.

Use this when: You want to see what happens when a page loads once.

Follow Mode - Real-Time Streaming

In follow mode, logget continuously watches the page and shows you events as they happen in real-time.

Use this when: You want to monitor a page that updates dynamically or makes ongoing requests.

Key Concepts

Invisible Browser

logget uses a "headless" browser - a browser that runs without a visible window. This allows it to work on servers and in automated environments.

Event-Driven

Everything logget captures is based on events: when a network request happens, when a console message appears, when an error occurs. logget listens to these events and records them.

Non-Intrusive

logget doesn't modify the web page or interfere with its behavior. It simply observes and records what happens naturally.

Flexible Output

The same captured data can be formatted in multiple ways, making it easy to use the results in different contexts (human reading, program processing, analysis tools).
