  {
    name: 'folder',
    contents: [
      { name: 'one.txt', contents: 'Hello World!' },

API

fsFromObject(path: String, tree: Object)

Creates the given tree representation at path.

Tree Nodes

Each node can have the following properties:

• name: Name of the file or folder
• contents: File or folder contents (optional)
• mtime: Modified time of a file or directory (optional)

ephemeralFsFromObject(tree: Object, task: Function<Promise>)

Creates an ephemeral path with the given tree in it. As soon as task resolves, the folder will get deleted.

The ephemeral path has the following signature:

`${os.tmpdir()}/${uuid.v4()}`

Example

ephemeralFsFromObject([{ name: 'index.txt', contents: 'test' }], (ephemeralPath) => {
    return fs.readFile(join(ephemeralPath, 'index.txt'))
    // -> test
}).then(() => {
  // folder deleted here
})
