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.
// default export is a minified version that doesn't need to
// load more than one file. Load the 'isexe/raw' export if
// you want the non-minified version for some reason.
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 })Check if the path is executable.
Will raise whatever errors may be raised by fs.stat, unless
options.ignoreErrors is set to true.
Same as isexe but returns the value and throws any errors raised.
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.
import type IsexeOptions from 'isexe'ignoreErrorsTreat all errors as "no, this is not executable", but don't raise them.uidNumber to use as the user id on posixgidNumber to use as the group id on posixpathExtList of path extensions to use instead ofPATHEXTenvironment variable on Windows.
