How to use the @faasjs/load.loadTs function in @faasjs/load

public async deploy () {
    const data = this.deployData;
    const loadResult = await loadTs(data.filename, { tmp: true });

    const func = loadResult.module;
    if (!func) {
      throw Error(`Func load failed: ${data.filename}`);
    }

    if (func.config) {
      data.config = deepMerge(data.config, func.config);
    }

    data.dependencies = deepMerge(loadResult.dependencies, func.dependencies);

    // 按类型分类插件
    const includedCloudFunction = [];
    for (let i = 0; i < func.plugins.length; i++) {
      const plugin = func.plugins[i as number];

// 删除 require 缓存
          if (!this.opts.cache && require.cache[cache.file as string]) {
            delete require.cache[cache.file as string];
          }
          // 直接 require ts 文件
          // eslint-disable-next-line security/detect-non-literal-require
          func = require(cache.file).default;
        } catch (error) {
          this.logger.error(error);
          // 删除 require 缓存
          if (require.cache[cache.file + '.tmp.js' as string]) {
            delete require.cache[cache.file + '.tmp.js' as string];
          }
          // 载入 ts 文件
          try {
            const ts = await loadTs(cache.file, { tmp: true });
            func = ts.module;
          } catch (error) {
            this.logger.error(error);
            res.statusCode = 500;
            res.write(error.message);
            res.end();
            return reject(error);
          }
        }
      }
      try {
        if (!cache.handler) {
          // 读取云函数配置并写入缓存
          func.config = loadConfig(this.root, path).development;
          // eslint-disable-next-line require-atomic-updates
          cache.handler = func.export().handler;
