cousteau

---

Recursive directory walker that retrieves all dir/file paths along with their stats and follows symlinks.

Features

• Traverses recursively and asynchronously all sub-directories.
• Can ignore artifacts via filtering mechanism based on CousteauStats properties.
• Properly resolves and follows symlinks. (filtering in symlinks is applied based on the original target artifact)
• Reports broken symlinks.

Install

$ npm install cousteau

API

The function accepts three arguments

cousteau(path, [ignoreOptions], callback)

• path - The target directory path
• ingoreOptions - Optional filtering option
• callback - The callback gets two arguments (errors, result) where result is an object with below structure

   // Result object
   {
       dirs: [CousteauStats],
       files: [CousteauStats],
       brokenSymlinks: [String],
   }

CousteauStats

Is an fs.Stats instance extended with the path property.

For example:

 
    {
      path string
      dev number
      mode number
      nlink number
      uid number
      gid number
      rdev number
      blksize number
      ino number
      size number
      blocks number
      atime Date object
      mtime Date object
      ctime Date object
      
      isFile function
      isDirectory function
      isBlockDevice function
      isCharacterDevice function
      isSymbolicLink function
      isFIFO function
      isSocket function
    }

The ignoreOptions can be applied to one or more of the CousteauStats properties either on the directories and/or the files.

Example

 
const cousteau = require("cousteau");
 
// Without filtering
cousteau("aPath", (errors, result) => {
    console.log(errors, result);
});
 
// Find all png files that their size is more than 1500 bytes
// and are children of directories that contain the "zilla" substring in their name
 
const ignoreOptions = {
    dir: {
        path: (p) => !p.includes("zilla"),
    },
    file: {
        path: (p) => !(/.*\.png$/i).test(p),
        size: (s) => s <= 1500,
    },
};
 
cousteau("aPath", ignoreOptions, (errors, result) => {
    console.log(errors, result);
});
