debug-tree

A simple library for debugging recursive operations with tree like debug output

Installation

$ npm install --save-dev debug-tree

Usage

The debug tree library is used with the standard console methods (log, info, warn, error). Just pass the first parameter as depth value.

const DebugTree = require('debug-tree');

...

console.log(DebugTree.depth(0), 'Root Log 1');
console.log(DebugTree.depth(1), 'Child Item 1');
console.log(DebugTree.depth(1), 'Child Item 2');
console.log(DebugTree.depth(2), 'Grand-Child Item 1');
console.log(DebugTree.depth(2), 'Grand-Child Item 2');
console.log(DebugTree.depth(0), 'Root Log 2');

...

The html output would look like:

For the console.log to output to a html file, initialize the DebugTree at the start of the application (or at the start of your test cases)

const DebugTree = require('debug-tree');

DebugTree.start('output.html');

// Use the DebugTree.end() method to end debugging with debug-tree.
// DebugTree.end();
