node-walk-sync

Return an array containing all recursive files and directories under a given directory, similar to Unix find. Follows symlinks. Bare-bones, but very fast.

Similar to wrench.readdirSyncRecursive, but adds trailing slashes to directories.

Not to be confused with node-walk, which has both an asynchronous and a synchronous API.

Installation

yarn add walk-sync

Usage

const walkSync = require('walk-sync');
const paths = walkSync('project')

Given project/one.txt and project/subdir/two.txt, paths will be the following array:

['one.txt', 'subdir/', 'subdir/two.txt']

Directories come before their contents, and have a trailing forward-slash (on all platforms).

Symlinks are followed.

Entries

Sometimes, it is important to get additional information from a walk of a directory; for instance if the downstream consumer needs to stat the files we can leverage the stats from the walk.

To accommodate, walkSync.entries(path [, options]) is also provided, instead of returning a list of files and/or directories it returns an array of objects which correspond to a given file or directory, except with more data.

entry.relativePath
entry.mode  // => fs.statSync(fullPath).mode
entry.size  // => fs.statSync(fullPath).size
entry.mtime // => fs.statSync(fullPath).mtime.getTime()

entry.isDirectory() // => true if directory

Options

• globs: An array of globs. Only files and directories that match at least one of the provided globs will be returned.

  const paths = walkSync('project', { globs: ['subdir/**/*.txt'] });
  // => ['subdir/two.txt']

  As an alternative to string globs, you can pass an array of precompiled minimatch.Minimatch instances. This is faster and allows to specify your own globbing options.

• directories (default: true): Pass false to only return files, not directories:

  const paths = walkSync('project', { directories: false })
  // => ['one.txt', 'subdir/two.txt']

• ignore: An array of globs. Files and directories that match at least one of the provided globs will be pruned while searching.

  const paths = walkSync('project', { ignore: ['subdir'] })
  // => ['one.txt']

• includeBasePath (default: false): Pass true to include the basePath in the output. note: this flag is only for walkSync(..) not walkSync.entries(..)

   const paths = walkSync('project', { includeBasePath: true });
   // => ['project/one.txt', 'project/subdir/two.txt']

• fs: Allows an alternative implementation of fs to be supplied. examples of alternative filesystems include memfs or graceful-fs

   import {Volume, createFsFromVolume} from 'memfs'
   const fs = createFsFromVolume(Volume.fromJSON({'aDir/aFile': 'some-contents'}))
   const paths = walkSync('project', { fs });
   // => ['aDir/', 'aDir/aFile']

Background

walkSync(baseDir) is a faster substitute for

glob.sync('**', {
  cwd: baseDir,
  dot: true,
  mark: true,
  strict: true
})
