file-tree-writer

This package provides utilities for defining and writing trees of files, e.g. when generating a large number files based on a template.

Install

# With yarn
yarn add file-tree-writer

# With npm
npm install file-tree-writer

Usage

The package exposes the createFileTreeWriter function to create the FileTreeWriter object.

It accepts a FileProps, DirectoryProps or SymbolicLinkProps object that you can create with the File, Directory and SymbolicLink functions. These descriptors contain the name and content of your file and its data (for files), children (for directories) and target for symbolic links. Additionally, you can set the mode of each generated file as a string, number or octal ('777' or '0o777'), owner (as a UID or by username) and group (as a GID or by group name).

You can then asynchronously write the file tree to a directory with fileTreeWriter.writeTo.

The FileTreeWriter object also exposes an EventEmitter-like interface to add event listeners for when a file has been written.

import { createFileTreeWriter, Directory, File, SymbolicLink } from 'file-tree-writer';

const files = Directory({
  name: 'some-dir',
  mode: '755',
  children: [
    File({
      name: 'some-file.txt',
      mode: '644',
      owner: 'root',
      group: 'root',
      data: '...',
    }),
    SymbolicLink({
      name: 'a-symlink',
      target: './some-file.txt',
    }),
  ],
});

const fileTreeWriter = createFileTreeWriter(files);
fileTreeWriter.on('write', e => console.info(`Writing ${e.path}`));

const main = async () => {
  await fileTreeWriter.writeTo('./out');
};

main();

This will print:

Writing out/some-dir
Writing out/some-dir/some-file.txt
Writing out/some-dir/a-symlink
