When a normal exception occurs, a stack trace like the following is outputted:
util.js:38 case '%s': return String(args[i++]); ^ TypeError: Cannot convert object to primitive value at String (unknown source) at util.js:38:25 at String.replace (native) at Object.<anonymous> (util.js:35:23) at Object.<anonymous> (console.js:25:36) at EventEmitter.<anonymous> (/project/src/routines/debug/boot.js:16:21) at EventEmitter.emit (/project/node_modules/eventemitter2/lib/eventemitter2.js:319:22) at /project/src/bootstrap.js:15:14 at /project/src/util/routineloader.js:36:11 at /project/src/util/routineloader.js:47:6 Which is very helpful. When I then do the following somewhere:
process.on('uncaughtException', function(err) { console.trace(); throw err; }); I only get:
Trace: at EventEmitter.<anonymous> (/project/src/routines/debug/exceptions.js:4:17) at EventEmitter.emit (events.js:88:20) Which is not helpful at all.
How do I make it return the entire stack trace, like the original one?

You can obtain a stack trace from a thread – by calling the getStackTrace method on that Thread instance. This invocation returns an array of StackTraceElement, from which details about stack frames of the thread can be extracted.
The stack trace is used to trace the active stack frames at a particular instance during the execution of a program. The stack trace is useful while debugging code as it shows the exact point that has caused an error. Errors in Node.
A full stack trace allows you to see the chain of files from when your custom tag reached your set breakpoint. If you click on any of the pages in the caller chain then FusionDebug will show you that page and will highlight the line at which the next page in the chain was called.
An error in Node. js is any instance of the Error object. Common examples include built-in error classes, such as ReferenceError , RangeError , TypeError , URIError , EvalError , and SyntaxError .
You're almost there:
process.on('uncaughtException', function(err) { console.log(err.stack); throw err; }); function foo() { throw new Error("HI. I'm an error."); } foo(); /* Prints Error: HI. I'm an error. at foo (/Users/rye/Desktop/test.js:7:9) at Object.<anonymous> (/Users/rye/Desktop/test.js:10:1) at Module._compile (module.js:441:26) at Object..js (module.js:459:10) at Module.load (module.js:348:31) at Function._load (module.js:308:12) at Array.0 (module.js:479:10) at EventEmitter._tickCallback (node.js:192:40) */ If you love us?
