isexe

Minimal module to check if a file is executable, and a normal file.

Uses fs.stat and tests against the PATHEXT environment variable on Windows.

USAGE

import { isexe, sync } from 'isexe'
// or require() works too
// const { isexe } = require('isexe')
isexe('some-file-name').then(isExe => {
  if (isExe) {
    console.error('this thing can be run')
  } else {
    console.error('cannot be run')
  }
}, (err) => {
  console.error('probably file doesnt exist or something')
})

// same thing but synchronous, throws errors
isExe = sync('some-file-name')

// treat errors as just "not executable"
const isExe = await isexe('maybe-missing-file', { ignoreErrors: true })
const isExe = sync('maybe-missing-file', { ignoreErrors: true })

API

isexe(path, [options]) => Promise<boolean>

Check if the path is executable.

Will raise whatever errors may be raised by fs.stat, unless options.ignoreErrors is set to true.

sync(path, [options]) => boolean

Same as isexe but returns the value and throws any errors raised.

Platform Specific Implementations

If for some reason you want to use the implementation for a specific platform, you can do that.

import { win32, posix } from 'isexe'
win32.isexe(...)
win32.sync(...)
// etc

// or:
import { isexe, sync } from 'isexe/posix'

The default exported implementation will be chosen based on process.platform.

Options

import type IsexeOptions from 'isexe'

• ignoreErrors Treat all errors as "no, this is not executable", but don't raise them.
• uid Number to use as the user id on posix
• gid Number to use as the group id on posix
• pathExt List of path extensions to use instead of PATHEXT environment variable on Windows.
