或没有外部依赖项：
var fs = require('fs');var path = require('path');var walk = function (dir, regExcludes, done) { var results = []; fs.readdir(dir, function (err, list) { if (err) return done(err); var pending = list.length; if (!pending) return done(null, results); list.forEach(function (file) { file = path.join(dir, file); var excluded = false; var len = regExcludes.length; var i = 0; for (; i < len; i++) { if (file.match(regExcludes[i])) { excluded = true; } } // Add if not in regExcludes if(excluded === false) { results.push(file); // Check if its a folder fs.stat(file, function (err, stat) { if (stat && stat.isDirectory()) { // If it is, walk again walk(file, regExcludes, function (err, res) { results = results.concat(res); if (!--pending) { done(null, results); } }); } else { if (!--pending) { done(null, results); } } }); } else { if (!--pending) { done(null, results); } } }); });};var regExcludes = [/index.html/, /js/lib.js/, /node_modules/];walk('.', regExcludes, function(err, results) { if (err) { throw err; } console.log(results);});
