While I love Node.js, I've found myself missing some functions. Things like recursively deleting/chmodding a directory (or even deep copying a directory), or even a basic line reader, shouldn't need to be re-invented time and time again.
That said, here's my attempt at a re-usable solution, at least until something more formalized gets integrated into Node.js (hint hint). wrench.js is fairly simple to use - check out the documentation/examples below:
npm install wrench
var wrench = require('wrench'),
util = require('util');// Recursively create directories, sub-trees and all.
wrench.mkdirSyncRecursive(dir, 0777);
// Recursively delete the entire sub-tree of a directory, then kill the directory
wrench.rmdirSyncRecursive('my_directory_name', failSilently);
// Recursively read directories contents.
wrench.readdirSyncRecursive('my_directory_name');
// Recursively chmod the entire sub-tree of a directory
wrench.chmodSyncRecursive('my_directory_name', 0755);
// Recursively chown the entire sub-tree of a directory
wrench.chownSyncRecursive("directory", uid, gid);
// Deep-copy an existing directory
wrench.copyDirSyncRecursive('directory_to_copy', 'location_where_copy_should_end_up');
// Read lines in from a file until you hit the end
var f = new wrench.LineReader('x.txt');
while(f.hasNextLine()) {
util.puts(x.getNextLine());
}
// Note: You will need to close that above line reader at some point, otherwise
// you will run into a "too many open files" error. f.close() or fs.closeSync(f.fd) are
// your friends, as only you know when it is safe to close.// Recursively read directories contents
var files = [];
wrench.readdirRecursive('my_directory_name', function(error, curFiles) {
// curFiles is what you want
