使用Node.js将文件系统中的目录结构转换为JSON

这是草图。错误处理留给读者练习。

var fs = require('fs'),    path = require('path')function dirTree(filename) {    var stats = fs.lstatSync(filename),        info = { path: filename, name: path.basename(filename)        };    if (stats.isDirectory()) {        info.type = "folder";        info.children = fs.readdirSync(filename).map(function(child) { return dirTree(filename + '/' + child);        });    } else {        // Assuming it's a file. In real life it could be a symlink or        // something else!        info.type = "file";    }    return info;}if (module.parent == undefined) {    // node dirTree.js ~/foo/bar    var util = require('util');    console.log(util.inspect(dirTree(process.argv[2]), false, null));}
