Express.js HBS模块-从.HBS文件注册部分文件

此代码将所有部分模板加载到目录中，并使它们按文件名可用：

var hbs = require('hbs');var fs = require('fs');var partialsDir = __dirname + '/../views/partials';var filenames = fs.readdirSync(partialsDir);filenames.forEach(function (filename) {  var matches = /^([^.]+).hbs$/.exec(filename);  if (!matches) {    return;  }  var name = matches[1];  var template = fs.readFileSync(partialsDir + '/' + filename, 'utf8');  hbs.registerPartial(name, template);});
