要 render 的 ejs 文件要放在 views folder 並取名為 index.ejs
let template = ejs.compile(str, options);
template(data);
// => Rendered HTML string
ejs.render(str, data, options);
// => Rendered HTML string
ejs.renderFile(filename, data, options, function (err, str) {
// str => Rendered HTML string
});It is also possible to use ejs.render(dataAndOptions); where you pass everything in a single object. In that case, you'll end up with local variables for all the passed options. However, be aware that your code could break if we add an option with the same name as one of your data object's properties. Therefore, we do not recommend using this shortcut.
