Stacktrace.js
stacktrace.js 是一个 JavaScript 库，旨在从不同 Web 浏览器的错误对象中生成和解析详细的函数调用栈。它作为一个栈追踪解析器和错误插桩工具，用于捕获执行流和错误轨迹。
该项目的特色在于其解析 Source Map 的能力，能够将压缩后的 JavaScript 栈追踪还原为原始源代码行。它还包含一个远程错误报告器，用于将处理后的异常数据和栈追踪传输到中央服务器进行分析。
该库涵盖了广泛的功能领域，包括错误轨迹提取、结构化轨迹生成和函数调用插桩。它利用环境特定的解析方式，将各种浏览器错误格式标准化为统一的对象模型。
Features
- JavaScript Error Trackers - Captures and analyzes function call stacks to identify the exact location of JavaScript errors in the browser.
- Stack Trace Capture - Generates detailed lists of function calls from error objects or specific execution points.
- Source Map Resolution - Translates minified line and column numbers back to original source code using external mapping files.
- Stack Trace Libraries - Provides a comprehensive library for generating and parsing detailed function call stacks from error objects.
- Function Wrapping Instrumentation - Provides a utility for wrapping functions to automatically capture and report execution flow and error traces.
- Uniform Error Objects - Converts diverse browser error formats into a uniform object model for consistent analysis.
- Client-Side Error Posting - Collects detailed error traces from user browsers and transmits them to a remote server for analysis.
- Source Map Resolution - Translates minified JavaScript stack traces back to original source lines using source map files.
- Stack Trace Generation - Captures the current function call stack and utilizes source maps to resolve minified code.
- Error Trace Extraction - Converts standard error objects into structured call lists to analyze exception locations.
- Browser Engine Parsers - Implements different parsing logic to handle varying stack trace formats across different browser engines.
- Code Execution Profilers - Tracks function call sequences and execution flows to analyze how specific code is being invoked.
- Regex-Based Output Parsing - Uses regular expressions to extract structured call data from raw browser error strings.
- Higher-Order Function Wrapping - Wraps target functions in a proxy to intercept calls and trigger stack capture during execution.
- Remote Stack Trace Transmission - Serializes processed stack data for transmission to a centralized debugging server.
- Error Reporting - Sends processed JavaScript stack traces and exception data to a remote server for debugging.
- Runtime Function Instrumentation - Wraps target functions to automatically capture and process a stack trace upon every invocation.
