I was exploring developing in Node.JS and found ExpressJS and RailwayJS (based on Express) which are frameworks for Node. The templating engine used Jade/EJS appears to be more for HTML. How might I generate JSON, eg. when I develop an API
我正在探索Node.JS的开发，发现ExpressJS和RailwayJS（基于Express）是Node的框架。使用Jade / EJS的模板引擎似乎更适合HTML。我怎样才能生成JSON，例如。当我开发API时

You just create normal JavaScript objects, for example:
您只需创建普通的JavaScript对象，例如：
var x = {
test: 1,
embedded: {
attr1: 'attr',
attr2: false
}
};
and
和
JSON.stringify(x);
turns it into JSON string. Note that x may contain functions which will be omitted. Also JSON.stringify returns x.toJSON() if .toJSON() is available.
把它变成JSON字符串。请注意，x可能包含将被省略的函数。如果.toJSON（）可用，JSON.stringify也会返回x.toJSON（）。

Express and Railway both extend off the HTTP module in node and both provide a "response" object as the second argument of the route/middleware handler's callback. This argument's name is usually shortened to res to save a few keystrokes.
Express和Railway都延伸到节点中的HTTP模块，并且都提供“响应”对象作为路由/中间件处理程序的回调的第二个参数。此参数的名称通常缩短为res以保存一些键击。
To easily send an object as a JSON message, Express exposes the following method:
为了轻松地将对象作为JSON消息发送，Express公开了以下方法：
res.json({ some: "object literal" });
Examples:
app.use(function (req, res, next) {
res.json({ some: "object literal" });
});
// -- OR -- //
app.get('/', function (req, res, next) {
res.json({ some: "object literal" });
});
Check out the docs at expressjs.com and the github source is well documented as well
查看expressjs.com上的文档，github源代码也有详细记录
