super-trace v0.0.9

quick start

npm install super-trace

import superTrace from 'super-trace';

function a(){
  superTrace.headerLog("started")
  b()
  c()
  e()
}

function b(){
  superTrace.log()
  d()
}

function c(){
  superTrace.log()
  var loop = 3;
  while (loop--) {
    d()
    e()
  }
}

function d(){
  superTrace.log()
}

function e() {
  superTrace.log()
}

a()

superTrace.superLog()

you will get following:

how to use

just use superTrace.headerLog as a beginning, then superTrace.log as a step setting in functions you interested in.

finally use superTrace.superLog you will see a call-stacks displayed as tree structure

for what

you can use superTrace to decode source code:

can not

if the SuperTrace.log was triggered by a settimeout or something similar, then tree can not created. But you can make this superTrace.log as a headerLog, then get the next flows.

if the SuperTrace.log was an orphan, it will be added to the session root as a special child, It's gray when been displayed.
