crawler is a collection of web scraping and JavaScript reverse engineering examples designed for learning how modern websites protect their data and how those protections can be analyzed. It contains many case studies that demonstrate how to analyze and replicate request parameters, cookies, and encryption logic used by real websites. Each directory in the project focuses on a specific target service or scenario, showing how browser network requests and JavaScript code can be studied to reproduce API calls programmatically. Many examples illustrate techniques such as debugging scripts, intercepting requests, analyzing encrypted parameters, and understanding authentication flows. crawler also explores common anti-scraping defenses and demonstrates how developers can examine them through debugging tools and reverse engineering techniques.

ast-hook-for-js-RE is an open source JavaScript reverse engineering toolkit designed to help analysts locate and understand client-side encryption logic used by web applications. It works by intercepting browser traffic through a local proxy server and modifying JavaScript code before it executes in the browser. Using Abstract Syntax Tree (AST) transformations, it injects hook functions into the code to monitor variable assignments and other runtime changes during execution. ...
