require-traverser

requireTraverser

A library for finding all the nested dependencies of a commonJS/node.js module. Uses 'detective' to traverse files.

Install

npm install require-traverser

Usage

var rt = require('require-traverser')

Two ways to call rt:

• one module: <directory>, <module>, [<opts>,] <errback>
• multiple modules: <moduleList>, [<opts>,] <errback>

where

• <directory> is the directory path from which to search for the module
• <module> is the module to get dependencies from
• <moduleList> is an array of objects like: {dir: , module: }
• <errback> is a standard node.js errback
• <opts> is optional, and can have any of the parameters:
  • isFile - function to asynchronously test whether a file exists. Takes the same parameters as fs.isFile.
  • readFile - function to read files asynchronously. Takes the same parameters as fs.readFile.

rt returns (to the errback) an object like:

{<filename>:
  {resolved: <dependencies>,
   unresolved: <require expressions that couldn't be resolved>,
   unfound: <require dependencies that couldn't be found>
  }
}

rt doesn't resolve node.js native libraries (returns them as 'unfound').
