问如何使用Node.js删除目录中的所有文件和子目录

EN

fs.rm(path_to_delete, { recursive: true }, callback)
// or use the synchronous version
fs.rmSync(path_to_delete, { recursive: true })

const fs = require("fs");
const path = require("path");

const DIR_TO_CLEAR = "./trash";

emptyDir(DIR_TO_CLEAR);

function emptyDir(dirPath) {
  const dirContents = fs.readdirSync(dirPath); // List dir content

  for (const fileOrDirPath of dirContents) {
    try {
      // Get Full path
      const fullPath = path.join(dirPath, fileOrDirPath);
      const stat = fs.statSync(fullPath);
      if (stat.isDirectory()) {
        // It's a sub directory
        if (fs.readdirSync(fullPath).length) emptyDir(fullPath);
        // If the dir is not empty then remove it's contents too(recursively)
        fs.rmdirSync(fullPath);
      } else fs.unlinkSync(fullPath); // It's a file
    } catch (ex) {
      console.error(ex.message);
    }
  }
}
