tree-manager

nodejs connector for jstree library.

To run the example go to example folder run npm install and point your browser to localhost:5000.

Initialization

var TreeManager = require('../lib/treemanager');
var rootDir = __dirname + '/test_dir_root';
var treeManager = new TreeManager(rootDir);

Set the root path whil instantiating the module.

You can change the root directory on the fly by calling treeManager.setRoot(path) with a path as an argument.

Methods

walkDir

Walks down recursivelly the root folder.

Example:

treeManager.walkDir(rootDir, function (err, tree) {
  console.log(tree);
});

Parameters:

• rootDirectory - absolute path to rd
• callback - function called on success or error, returns error object or an object with the directory structure

createNode

Creates a new file or folder

Example:

var type = 'file';
var filename = path.join(req.query.id, req.query.text);
treeManager.createNode(filename, type, function (res) {
  console.log(res);
});

Parameters:

• name - path to a new file or folder
• type - file or folder
• callback - function called on success or error, returns error object or new folder or file name.

renameNode

Renames a file or folder

treeManager.renameNode('some_dir/note.txt', 'note_changed.txt', function (res) {
  console.log(res);
});

Parameters:

• oldPath - path to the current file or folder

Tests

To perform tests run npm test in the tree-manager root directory.

TODO

• 2 option for folder removal - recursive with all subfolders and files and only empty
• check performance of walkDir function for larger directory structure
• check uniqueness after renaming and moving - server side
• write file to example
