Global methods

`checkDirectory(location: String)`

Checks if a string is a valid path to a directory and expands it. It throw verbose errors depending on why the directory is not valid.

import { checkDirectory } from '@universal-packages/fs-utils'

const finalPath = checkDirectory('./src')

console.log(finalPath)

// > /Users/david/project/src

import { checkDirectory } from '@universal-packages/fs-utils'

try {
  const finalPath = checkDirectory('./src/fake')
} catch (error) {
  console.log(error)
}

// > Error "/Users/david/project/src/fake" does not exists
// > Error "/Users/david/project/src/fake" is not a directory or can not be accessed

`quickCheckDirectory(location: String)`

It does the same as checkDirectory but returns false if the directory is not valid instead of throwing an error.

import { quickCheckDirectory } from '@universal-packages/fs-utils'

const finalPath = quickCheckDirectory('./src/fake')

console.log(finalPath)

// > false

`checkFile(location: String)`

Checks if a string is a valid path to a file and expands it. It throw verbose errors depending on why the file is not valid.

import { checkFile } from '@universal-packages/fs-utils'

const finalPath = checkFile('./src/README.md')

console.log(finalPath)

// > /Users/david/project/src/README.md

import { checkFile } from '@universal-packages/fs-utils'

try {
  const finalPath = checkFile('./src/NOT.md')
} catch (error) {
  console.log(error)
}

// > Error "/Users/david/project/src/NOT.md" does not exists
// > Error "/Users/david/project/src/NOT.md" is not a file or can not be accessed

`quickCheckFile(location: String)`

It does the same as checkFile but throw verbose errors depending on why the file is not valid.

import { quickCheckFile } from '@universal-packages/fs-utils'

const finalPath = quickCheckFile('./src/README.md')

console.log(finalPath)

// > /Users/david/project/src/README.md

`ensureDirectory(location: String)`

Checks and expand a path and tries to create the directory if the check fails.

import { ensureDirectory } from '@universal-packages/fs-utils'

const finalPath = ensureDirectory('./src/tmp')

console.log(finalPath)

// > /Users/david/project/src/tmp

Any other case is thrown as an error.

import { ensureDirectory } from '@universal-packages/fs-utils'

try {
  const finalPath = ensureDirectory('/new')
} catch (error) {
  console.log(error)
}

// > Error Directory "/new" is an invalid path or greater permissions are required

`ensureFile(location: String)`

Checks and expand a path and tries to create an empty file if the check fails

import { ensureFile } from '@universal-packages/fs-utils'

const finalPath = ensureFile('./src/tmp/development.log')

console.log(finalPath)

// > /Users/david/project/src/tmp/development.log

Any other case is thrown as an error.

import { ensureFile } from '@universal-packages/fs-utils'

try {
  const finalPath = ensureFile('/file.rb')
} catch (error) {
  console.log(error)
}

// > Error File location "/file.rb" is an invalid path or greater permissions are required

`expandPath(location: String)`

Tries to expand a path by resolving the tilde and resolving to an absolute path.

import { expandPath } from '@universal-packages/fs-utils'

console.log(expandPath('./src/tmp'))
console.log(expandPath('~/directory'))
