扫描目录，支持遍历，支持过虑

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

function scanDirSync(dirPath, options) {
  const defaultOptions = {
    recursive: true,
    ignore: [],
    include: [],
    exclude: [],
  };
  const { recursive, ignore, include, exclude } = Object.assign(
    defaultOptions,
    options,
  );
  const arr = [];

  readDir(dirPath, recursive, ignore, include, exclude);
  return arr;

  function readDir(dirPath, recursive, ignore, include, exclude) {
    const files = fs.readdirSync(dirPath);

    files.forEach((file) => {
      const fullPath = path.join(dirPath, file);

      // 如果是目录并且满足条件则继续遍历
      if (
        fs.statSync(fullPath).isDirectory() &&
        !ignore.includes(file) &&
        recursive
      ) {
        return readDir(fullPath, recursive, ignore, include, exclude);
      }

      // 如果是文件且满足条件则存入数组
      if (fs.statSync(fullPath).isFile()) {
        const extName = path.extname(fullPath); // 文件扩展名

        // 是否在ignore列表中
        const inIgnore = ignore.some((item) => {
          return item === file;
        });
