Package Exports

@distributed-systems/stack-trace
@distributed-systems/stack-trace/StackTrace.js
@distributed-systems/stack-trace/npm/src/StackTrace.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@distributed-systems/stack-trace) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Get a Stack-Trace

const st = new StackTrace();
const err = new Error('I want a structured stack trace!');

// gets a structured stack from the error passed in
const trace = st.getStack(err);

Get a Stack-Trace with a base directory removed from the file paths

const st = new StackTrace();
const err = new Error('I want a structured stack trace!');

// if a frame has a file in the directory defined in the variable below, 
// the portion defined here will be removed from its path 
const baseDir = '/home/ee';

// gets a structured stack from the error passed in
const trace = st.getStack(err, baseDir);

TBD: node 12 can be used with --async-stack-traces
