Get the current package's binary path (using the package.json bin or directories.bin field).

This is useful when testing a package's binary. Using get-bin-path (as opposed to hard-coding the path to the binary):

  • validates that the package.json bin or directories.bin field is correctly setup
  • decouples the binary path from the tests, which allows moving the file without rewriting the tests

Hire me

Please reach out if you're looking for a Node.js API or CLI engineer (11 years of experience). Most recently I have been Netlify Build's and Netlify Plugins' technical lead for 2.5 years. I am available for full-time remote positions.

Examples

import { getBinPath } from 'get-bin-path'

// `binPath` is the absolute path to the current package's binary
const binPath = await getBinPath()
// Test runner
import test from 'ava'
// Library to execute child processes / commands
import { execa } from 'execa'

import { getBinPath } from 'get-bin-path'

const binPath = await getBinPath()

test('Binary file should return "true"', async (t) => {
  const { stdout } = await execa(binPath)
  t.is(stdout, 'true')
})

Install

npm install get-bin-path

This package works in Node.js >=18.18.0.

This is an ES module. It must be loaded using an import or import() statement, not require(). If TypeScript is used, it must be configured to output ES modules, not CommonJS.

API

getBinPath(options?)

options: object
Returns: Promise<string | undefined>

Returns the current package's binary absolute path. When no package.json or binary can be found, undefined is returned instead.

import { getBinPath } from 'get-bin-path'

const binPath = await getBinPath()

getBinPathSync(options?)

options: object
Returns: string | undefined

Same but synchronous.

import { getBinPathSync } from 'get-bin-path'

const binPath = getBinPathSync()

options

Type: object

options.name

Type: string
Default: package.json name field

Name of the binary.

Only needs to be specified when the package exports several binaries in the package.json bin or directories.bin field.

{
  "name": "foo",
  "bin": {
    "foo": "path/to/foo.js",
    "bar": "path/to/bar.js"
  }
}

When the package.json's bin or directories.bin field is a string, the package name field must match the name option.

options.cwd

Type: string
Default: Current directory

Override the current directory, which is used when retrieving the package.json.
