node-rd's Introduction

NPM version build status Test coverage David deps node version npm download npm license

node-rd

列出(遍历)目录下的所有文件,包括子目录(支持 TypeScript)

安装

$ npm install rd --save

API列表

说明:

  • read 开头表示返回数组结果
  • each 开头表示每发现一个文件均调用回调函数 findOne
  • Sync 结尾表示是同步函数,其他表示异步函数

可用的API(详细用法可参考 test/test.js ):

  • read(dir, [threads], callback)
  • readFilter(dir, pattern, [threads], callback)
  • readFile(dir, [threads], callback)
  • readFileFilter(dir, pattern, [threads], callback)
  • readDir(dir, [threads], callback)
  • readDirFilter(dir, pattern, [threads], callback)
  • each(dir, findOne, [threads], callback)
  • eachFilter(dir, pattern, [threads], findOne, callback)
  • eachFile(dir, [threads], findOne, callback)
  • eachFileFilter(dir, pattern, [threads], findOne, callback)
  • eachDir(dir, [threads], findOne, callback)
  • eachDirFilter(dir, pattern, [threads], findOne, callback)

说明:

  • 以上所有函数均提供同步版本,如 read 对应的同步版本为 readSync; 相应的 callback 改为直接 return 返回值;
  • threads 参数表示并发数量,为可选参数,默认为1;同步版本没有此参数;

findOne 回调函数格式:

function findOne(filename, stats) {
  // filename 是当前文件的完整路径
  // stats 是使用 fs.Stats 对象
}

callback 回调函数格式:

function callback(err, list) {
  // 如果出错,err为出错信息
  // each系列函数没有list参数
  // read系列函数list为完整文件名的列表
}

pattern 参数格式:

  • 正则表达式
  • 函数
function pattern(filename) {
  // filename 是当前文件的完整路径
  // 返回 true 表示该文件名符合条件
}

简单示例

var rd = require('rd');

// 异步列出目录下的所有文件
rd.read('/tmp', function (err, files) {
  if (err) throw err;
  // files是一个数组,里面是目录/tmp目录下的所有文件(包括子目录)
});

// 同步列出目录下的所有文件
var files = rd.readSync('/tmp');

// 异步遍历目录下的所有文件
rd.each('/tmp', function (f, s, next) {
  // 每找到一个文件都会调用一次此函数
  // 参数s是通过 fs.stat() 获取到的文件属性值
  console.log('file: %s', f);
  // 必须调用next()才能继续
  next();
}, function (err) {
  if (err) throw err;
  // 完成
});

// 同步遍历目录下的所有文件
rd.eachSync('/tmp', function (f, s) {
  // 每找到一个文件都会调用一次此函数
  // 参数s是通过 fs.stat() 获取到的文件属性值
  console.log('file: %s', f);
});

// 同步遍历目录下的所有js文件
rd.eachFileFilterSync('/path', /\.js$/, function (f, s) {
  console.log(f);
});
