resolve-from

What is resolve-from?

The resolve-from npm package is a module that allows you to resolve the path of a module like require.resolve() but from a given path. It is useful for situations where you need to resolve modules from a different directory than the current file's directory.

What are resolve-from's main functionalities?

Resolve the path of a module from a given path

This feature allows you to resolve the path of a module from a specific directory. You provide the directory as the first argument and the module name as the second argument. It returns the resolved path to the module.

const resolveFrom = require('resolve-from');
const modulePath = resolveFrom('/some/path', 'some-module');

Silently resolve the path of a module or return null

This feature is similar to the first, but it will return null instead of throwing an error if the module cannot be found. This is useful for cases where you want to check for a module's existence without causing an exception.

const resolveFrom = require('resolve-from');
const modulePath = resolveFrom.silent('/some/path', 'non-existent-module');

Other packages similar to resolve-from

resolve

The 'resolve' package is similar to 'resolve-from' in that it helps to resolve the path of a module. However, 'resolve' provides more options and flexibility, such as the ability to customize the resolution algorithm or to resolve based on the package.json's 'main' field.

enhanced-resolve

The 'enhanced-resolve' package is used by webpack and offers a highly configurable resolution mechanism that can resolve files, directories, and modules. It is more complex and feature-rich compared to 'resolve-from', which is simpler and more straightforward.

browser-resolve

The 'browser-resolve' package is designed to resolve modules for browser environments, taking into account the 'browser' field in package.json. It is similar to 'resolve-from' but is specifically tailored for browser-based module resolution.

Install

$ npm install resolve-from

Usage

const resolveFrom = require('resolve-from');

// There is a file at `./foo/bar.js`

resolveFrom('foo', './bar');
//=> '/Users/sindresorhus/dev/test/foo/bar.js'

API

resolveFrom(fromDir, moduleId)

Like require(), throws when the module can't be found.

resolveFrom.silent(fromDir, moduleId)

Returns null instead of throwing when the module can't be found.

fromDir

Type: string

Directory to resolve from.

moduleId

Type: string

What you would use in require().

Tip

Create a partial using a bound function if you want to resolve from the same fromDir multiple times:

const resolveFromFoo = resolveFrom.bind(null, 'foo');

resolveFromFoo('./bar');
resolveFromFoo('./baz');
