Uses a breadth-first search, when necessary, to resolve the file path using the correct casing, and verify that the file actually exists. Returns consistent results regardless of case sensitivity of the file path and/or operating system.

Detects if a file exists and returns the resolved filepath.

Install

Install with npm:

$ npm install --save detect-file

Install with yarn:

$ yarn add detect-file

Usage

var detect = require('detect-file');

API

detect

Detect the given filepath if it exists.

Params

  • filepath {String}: filepath to detect.
  • options {Object}: Additional options.
  • options.nocase {Boolean}: Set this to true to force case-insensitive filename checks. This is useful on case sensitive file systems.
  • returns {String}: Returns the detected filepath if it exists, otherwise returns null.

Example

var res = detect('package.json');
console.log(res);
//=> "package.json"

var res = detect('fake-file.json');
console.log(res)
//=> null

Case sensitive file systems

When using the nocase option, this library will attempt to detect the filepath with the following methods:

  1. Try to read all files in the filepath using fs.readdirSync. If successful and filepath is a directory, return the filepath.
  2. Try to read all files in the filepath's directory using fs.readdirSync. If successful, do case insensitive comparasions of the filepath to the files in filepath's directory.
