How does stack-trace.parse work?
stack-trace.parse is a function provided by the stack-trace library for parsing a string representation of a stack trace. When called with a string representation of a stack trace, stack-trace.parse processes the input and extracts relevant information such as the file name, line number, and column number for each stack frame. It then constructs an array of structured stack frame objects, each containing this information. The output format of the array is an array of objects with the following properties: fileName: The name of the file containing the code for the stack frame. lineNumber: The line number in the file where the stack frame occurs. columnNumber: The column number in the file where the stack frame occurs. functionName: The name of the function being executed at the time of the stack frame. This information can be useful for debugging and logging purposes, as it allows developers to identify the precise location in their code where errors are occurring.

const stackTrace = require("stack-trace"); const error = new Error("Something went wrong"); const trace = stackTrace.parse(error); trace.forEach((frame) => { console.log(`At ${frame.fileName}:${frame.lineNumber}`); console.log(`Function: ${frame.functionName}`); });
In this example, we use stack-trace.parse to parse the stack trace of an error object. We first create an Error object with a custom error message. We then pass this object to stack-trace.parse, which extracts the relevant information from the error's stack trace. We then iterate over each stack frame in the resulting array of stack frames and log the file name, line number, and function name of each frame to the console. Note that stack-trace is a third-party library that needs to be installed before it can be used.
