response.data

response.data

let res = metro.response({
	method: 'POST',
	body: {
		foo: 'bar'
	}
})
console.log(res.data) // prints { foo: "bar" }

Whenever you set a body on a Response, you can later access the original body parameter as response.data. If you access response.body, you will see that it is transformed into a ReadableStream, which can only be read once. The metro.response() function adds the data property.
