recursive-readdir-ext v2.3.0

recursive-readdir-ext

Recursively list all files in a directory and its subdirectories. It does not list the directories themselves.

Because it uses fs.readdir, which calls readdir under the hood on OS X and Linux, the order of files inside directories is not guaranteed.

The library is a based on recursive-readdir by Jamison Dance jergason@gmail.com (http://jamisondance.com/)

Installation

npm install recursive-readdir-ext

Usage

var recursive = require("recursive-readdir-ext");

recursive("some/path", function(err, files) {
  // `files` is an array of file paths
  console.log(files);
});

It can also take a list of files to ignore.

var recursive = require("recursive-readdir");

// ignore files named "foo.cs" or files that end in ".html".
recursive("some/path", ["foo.cs", "*.html"], function(err, files) {
  console.log(files);
});

You can also pass functions which are called to determine whether or not to ignore a file:

var recursive = require("recursive-readdir");

function ignoreFunc(file, stats) {
  // `file` is the path to the file, and `stats` is an `fs.Stats`
  // object returned from `fs.lstat()`.
  return stats.isDirectory() && path.basename(file) == "test";
}

// Ignore files named "foo.cs" and descendants of directories named test
recursive("some/path", ["foo.cs", ignoreFunc], function(err, files) {
  console.log(files);
});

Promises

You can omit the callback and return a promise instead.

readdir("some/path").then(
  function(files) {
    console.log("files are", files);
  },
  function(error) {
    console.error("something exploded", error);
  }
);

The ignore strings support Glob syntax via minimatch.

Custom file system

You can now pass in an options object in place of ignores, so that you can pass in a custom filesystem as an fs option. This is ideal for testing or when operating on an in-memory file system etc.

import { fs, vol } from "memfs";

const fileStruct = {
  "./README.md": "# hello",
  "./src/index.js": "1 + 2;",
  "./node_modules/debug/index.js": "2 + 3;"
};
vol.fromJSON(fileStruct, "/app");

const successFn = files => console.log(files);
const errFn = err => console.error(err);

You can also pass debugging and logging options to monitor how the file structure is processed, what files are ignore etc.

// using promise API
recursive("/app", {
  ignores: ["README.md"],
  fs, // in-memory fs
  debug: true,
  log: (...msg) => console.log("readdir", ...msg)
}).then(successFn, errFn);
