What is stacktrace-js?

The stacktrace-js package is a JavaScript library that provides stack traces for debugging JavaScript applications. It helps developers to better understand and debug their code by providing detailed information about the call stack when an error occurs.

What are stacktrace-js's main functionalities?

Generating stack traces

This feature allows developers to generate and capture stack traces within their applications. The code sample demonstrates how to obtain a stack trace and convert it into a readable string format.

StackTrace.get().then(function(stackframes) { var stringifiedStack = stackframes.map(function(sf) { return sf.toString(); }).join('\n'); console.log(stringifiedStack); });

Instrumenting functions to automatically attach stack traces

This feature automatically attaches stack traces to errors thrown in instrumented functions. The code sample shows how to instrument a function and handle errors with attached stack traces.

function foo() { throw new Error('Bazinga!'); } foo = StackTrace.instrument(foo, function(stackframes) { var stringifiedStack = stackframes.map(function(sf) { return sf.toString(); }).join('\n'); console.log(stringifiedStack); }, function(err) { console.log(err.message); }); foo();
