npm install discover-path
Check for the existence of a path in a case-sensitive manner and, if not found, suggest where it might be at.
Note that this is a slow operation (recursively listing directory contents), and should only be used in cases where that's fine (CLI tools in the case of errors, for instance).
``sh`
$ npm install discover-path
`js
import {discoverPathSync} from 'discover-path'
const expectedPath = '/Users/Rexxars/webdev/discover-Path'
const actualPath = discoverPathSync(expectedPath)
// If a "direct" match is found (1:1, or on case-changes with only one option:)
console.log(actualPath) // /Users/rexxars/webdev/discover-path
`
- If a 1:1 match can be found (or, if changing the casing of paths, only one option is found), the actual, "fixed" (case-sensitive) path is returned.
- If no direct matches was found, or its unclear which alternative to use, it will throw an error. The error object contains a list of suggestions if any can be found. This array of options can also be found on the suggestions property on the error.
`js
import {discoverPathSync} from 'discover-path'
try {
const expectedPath = '/Users/rexxars/webdev/Discover-Path'
const actualPath = discoverPathSync(expectedPath)
} catch (err) {
console.log(err.code) // 'ENOENT'
console.log(err.path) // '/Users/rexxars/webdev/Discover-Path'
console.log(err.suggestions)
/*
[
'/Users/rexxars/webdev/discover-path',
'/Users/rexxars/webdev/discover-Path'
]
*/
console.log(err.message)
/*
Cannot find path '/Users/Rexxars/webdev/Discover-Path'
Did you mean:
- /Users/rexxars/webdev/discover-path
- /Users/rexxars/webdev/discover-Path
