Simple remove comments in project

RemoveComments.js

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

const IgnoreFiles = ["node_modules", ".idea", ".vscode", "package-lock.json", "yarn.lock"];

class RemoveComments {

        const curPath = path.join(folderPath, file);
        if (fs.lstatSync(curPath).isDirectory()) {
          this.deleteFolderRecursive(curPath);
        } else {
          fs.unlinkSync(curPath);
        }
      });
      fs.rmdirSync(folderPath);
    }
  }
  static copyDirectorySync(source, target) {
    // 创建目标目录
    if (!fs.existsSync(target)) {

        this.copyDirectorySync(sourcePath, targetPath);
      } else {
        // 复制文件
        fs.copyFileSync(sourcePath, targetPath);
      }
    });
  }
  static removeCommentsFromFile(filePath) {
    let fileContent = fs.readFileSync(filePath, "utf8");

    // 移除单行注释，eg： const a = 1; // comment
    fileContent = fileContent.replace(/\/\/.*$/gm, "");

    // 移除单行注释
    fileContent = fileContent.replace(/^\/\/.*\n?/gm, "");

    // 移除多行注释

    // 移除连续的空白行
    fileContent = fileContent.replace(/\n+/g, "\n");

    fs.writeFileSync(filePath, fileContent, "utf8");
  }

  static removeCommentsFromDirectory(directoryPath) {
    fs.readdir(directoryPath, (err, files) => {
      if (err) {
        console.error("Error reading directory:", err);
        return;
      }

      files.forEach((file) => {
        const filePath = path.join(directoryPath, file);
        const stats = fs.statSync(filePath);

        if (stats.isDirectory()) {
          this.removeCommentsFromDirectory(filePath);
        } else if (stats.isFile() && path.extname(filePath) === ".js") {
          this.removeCommentsFromFile(filePath);
        }
      });
    });
  }

  run() {
    if (fs.existsSync(this.targetPath)) {
      RemoveComments.deleteFolderRecursive(this.targetPath);
    }
    RemoveComments.copyDirectorySync(this.sourcePath, this.targetPath);
    RemoveComments.removeCommentsFromDirectory(this.targetPath);
  }
}

After removing comments, do format to fix empty-line problems: npx prettier --write "**/*.js"
