require-time-tree

Calculate a tree object for all require statements with timing

Usage

npm install require-time-tree

var requireTree = require('..');
 
// This clears any previous tree and "starts fresh".  This overrides the
// underlying Module._load function to keep this accounting.
requireTree.start();
 
require('util');
require('console');
require('http');
require('fs');
require('../tests/lib/foo');
 
// Restore the original Module._load function
requireTree.stop();
 
// Get the current tree
var tree = requireTree.getTree();
 
// Pretty-print the tree formatted nicely
requireTree.printTree(tree);
 
// Print the raw tree
console.log(JSON.stringify(tree, null, 2));
