locate-path

What is locate-path?

The locate-path npm package is designed to find a file or directory by looking for it in multiple paths. It is useful for situations where you need to locate a file but are unsure of its exact location within a list of possible directories. It can be used synchronously or asynchronously and supports both promises and async/await syntax.

What are locate-path's main functionalities?

Asynchronous Path Location

This feature allows you to asynchronously locate a file or directory from an array of paths. The first path that contains the file or directory is returned.

const locatePath = require('locate-path');

(async () => {
  const foundPath = await locatePath(['unicorn.png', 'rainbow.png'], {cwd: 'images'});
  console.log(foundPath);
  //=> 'images/unicorn.png'
})();

Synchronous Path Location

This feature provides a synchronous way to locate a file or directory from an array of paths. It is useful when you need to find a path in a blocking manner.

const locatePath = require('locate-path');

const foundPath = locatePath.sync(['unicorn.png', 'rainbow.png'], {cwd: 'images'});
console.log(foundPath);
//=> 'images/unicorn.png'

Other packages similar to locate-path

find-up

The find-up package is similar to locate-path in that it helps you find a file or directory by searching upwards from a given directory. It differs in that it searches up the directory tree, starting from the current directory, rather than across a list of specified paths.

globby

Globby is a package that allows you to find files using glob patterns. While locate-path is used to find a file from a list of paths, globby can search for files matching patterns, which can be more flexible in certain scenarios.

resolve-from

Resolve-from is a package that resolves the path of a module from a given path, similar to require.resolve but from a specified directory. It is more specific to module resolution compared to locate-path which is for general file or directory location.

README

locate-path

Get the first path that exists on disk of multiple paths

Install

$ npm install --save locate-path

Usage

Here we find the first file that exists on disk, in array order.

const locatePath = require('locate-path');

const files = [
	'unicorn.png',
	'rainbow.png', // only this one actually exists on disk
	'pony.png'
];

locatePath(files, {concurrency: 1}).then(foundPath => {
	console.log(foundPath);
	//=> 'rainbow'
});
