node-fixturify

Convert JSON objects into directory structures on the file system, and back
again. This package is primarily useful for writing tests.

Installation

 yarn add fixturify

Usage

 const fixturify = require('fixturify')

const obj = {
  'foo.txt': 'foo.txt contents',
  'subdir': {
    'bar.txt': 'bar.txt contents'
  }
}

fixturify.writeSync('testdir', obj) // write it to disk

fixturify.readSync('testdir') // => deep-equals obj

fixturify.readSync('testdir', { globs: ['foo*'] }) // glob support
// => { foo.txt: 'foo.text contents' }

fixturify.readSync('testdir', { ignore: ['foo*'] }) // glob support
// => { subdir: { bar.txt: 'bar.text contents' } }

fixturify.writeSync('testDir', {
  'subdir': { 'bar.txt': null }
}) // remove subdir/bar.txt

fixturify.readSync('testdir') // => { foo.txt: 'foo.text contents' }

fixturify.writeSync('testDir', {
  'subdir': null
}) // remove subdir/

 const fixturify = require('fixturify')

const obj = {
  'subdir': {
    'foo.txt': 'foo.txt contents'
  },
  'emptydir': {}
}

fixturify.writeSync('testdir', obj) // write it to disk

fixturify.readSync('testdir', { ignoreEmptyDirs: true })
// => { subdir: { foo.txt': 'foo.txt contents' } }

File contents are decoded and encoded with UTF-8.

fixture.readSync follows symlinks. It throws an error if it encounters a
broken symlink.

Limitations

To keep the API simple, node-fixturify has the following limitations:

• Reading or setting file stats (last-modified time, permissions, etc.) is
  not supported.

• Creating symlinks is not supported. Symlinks are traversed when reading. Broken symlinks throw.

• Special files like FIFOs, sockets, or devices are not supported.

• File contents are automatically encoded/decoded into strings. Binary files
  are not supported.
