Nodejs 获取指定文件夹下所有文件及文件夹

文件递归扁平化输出

代码

const fs = require('fs').promises;
const path = require('path');

// 递归获取文件夹下所有文件
async function flatFiles(dirPath) {
    try {
        const filesList = [];
        await readFile(dirPath, filesList);
        return filesList;
    } catch (error) {
        console.error('Error reading directory:', error);
        throw error;
    }
}

// 遍历读取文件
async function readFile(currentPath, filesList) {
    const files = await fs.readdir(currentPath);
    for (const file of files) {
        const filePath = path.join(currentPath, file);
        const stats = await fs.stat(filePath);
        if (stats.isDirectory()) {
            await readFile(filePath, filesList);
        } else {
            // 创建一个对象保存信息
            const obj = {};
            obj.size = stats.size; // 文件大小，以字节为单位
            obj.name = file; // 文件名
            obj.path = filePath; // 文件绝对路径
            filesList.push(obj);
        }
    }
}
const dirPath = 'E:/.temp/pdf/.idea';
(async () => {
    try {
        const list = await flatFiles(dirPath);
        console.log(JSON.stringify(list, null, 2));
    } catch (error) {
        console.error('Failed to get files and folders:', error);
    }
})();

文件及文件夹以树状结构输出

代码

const fs = require('fs').promises;
const path = require('path');

// 获取文件夹下所有文件和子文件夹
async function treeFolderFiles(dirPath) {
    try {
        const items = await fs.readdir(dirPath);
        const result = [];

        for (const item of items) {
            const itemPath = path.join(dirPath, item);
            const stat = await fs.stat(itemPath);

            if (stat.isDirectory()) {
                let data = {

                };
                let children = await treeFolderFiles(itemPath);
                if (children.length > 0) {
                    data.children = children;
                }
                result.push(data);
            } else {
                result.push({

                    path: itemPath,
                    size: stat.size
                });
            }
        }

        return result;
    } catch (error) {
        console.error(`Error reading directory ${dirPath}:`, error);
        throw error;
    }

const dirPath = 'E:/.temp/pdf/.idea';
