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 });
