Directory Traversal

Sometimes you just need a way to map a directory to either load modules in real time or just get the available files to run a task, directory traversal will map a directory for you and deliver a convenient DirectoryMap object for you.

Install

npm install @universal-packages/directory-traversal

Global methods

traverse(locations: String, [options])

The traverse function will go recursively from a root directory until it maps the whole tree, you can execute a callback for every visited directory after being mapped, limit the depth and filter for files you want or you not want to be mapped, returning a DirectoryMap object

import { traverse } from '@universal-packages/directory-traversal'

const directoryMap = traverse('~/projects')

console.log(directoryMap)

Options

You can modify the behavior of the traverse function by providing options.

• callback Function A function to call for every mapped directory for you to analyze in place, return false if you want to stop going deeper into that directory.

  const directoryMap = traverse('~/projects', {
    callback: (directoryMap) => {
      if (directoryMap.path.include('homework')) {
        return false
      }
    }
  })

• fileFilter (yml | yaml | js | json)[] | Regex To only include files that satisfies this condition.

• maxDepth Number To only map files going this level deep.

DirectoryMap

From the traverse example you will get something like this:

{
  "path": "home/projects",
  "files": [],
  "directories": [
    {
      "path": "home/projects/universal-directory-traversal",
      "files": [
        "home/projects/universal-directory-traversal/.editorconfig",
        "home/projects/universal-directory-traversal/.gitignore",
        "home/projects/universal-directory-traversal/CODE-OF-CONDUCT.md",
        "home/projects/universal-directory-traversal/CONTRIBUTING.md",
        "home/projects/universal-directory-traversal/LICENSE.md",
        "home/projects/universal-directory-traversal/README.md",
        "home/projects/universal-directory-traversal/package-lock.json",
        "home/projects/universal-directory-traversal/package.json",
        "home/projects/universal-directory-traversal/tsconfig.dis.json",
        "home/projects/universal-directory-traversal/tsconfig.json"
      ],
      "directories": []
    }
  ]
}
