directory-crawler

The directory crawler library by Node.JS

install

npm install directory-crawler

function crawlingDirStream(depth=Infinity, concurrency, ...dirPaths) : stream(dirent)

• depth - Number (0 ~ Infinity)
• concurrency - Number
• dirPaths - String Array
• return stream (Dirent)
  • name - String
  • path - String - absolute parent directory path
  • [Symbol(type)] - Symbol - file type

usage

import { crawlingDirStream } from 'directory-crawler'

// 처음 파일시스템에 접근할때 좀더 시간이 오래걸리기 때문에 미리 한번 실행해준다
for await (const d of crawlingDirStream(0, 1, './', '../')) {}

let lasttime = process.hrtime.bigint()
for await (const d of crawlingDirStream(Infinity, 1, './', '../')) {
}
console.log(process.hrtime.bigint() - lasttime); // 2879583000n


lasttime = process.hrtime.bigint()
// let count = 0
for await (const d of crawlingDirStream(Infinity, 10, './', '../')) {
    // console.log(count +=1, d);
}
console.log(process.hrtime.bigint() - lasttime); // 1222789700n

crawlingDir(depth, dir): Promise(Array(Dirent))

• depth - Number (0 ~ Infinity)
• dirPaths - String Array
• return Promise(Array(Dirent))
  • name - String
  • path - String - absolute parent directory path
  • [Symbol(type)] - Symbol - file type

usage

import { crawlingDirStream } from 'directory-crawler'

let lasttime = process.hrtime.bigint()
crawlingDir(Infinity, '../').then((files) => {
    console.log(files);
    console.log(process.hrtime.bigint() - lasttime); // 463462000n
