Hapi.js-如何获取渲染视图的序列化表示

Question

I would like to cache rendered views in Hapi.js (using the Vision plugin for rendering view templates), but haven't been able to find out how to do it. What I need to know is

1. How do I get a serialized representation of a rendered view, which I can cache?
2. How should I reply to the client with a serialized rendering that I got from the cache?

Currently, cache-less, my code for rendering views in response to client requests is quite straightforward, basically like this (irrelevant code left out):

// renderIndex is a Hapi.js request handler
let renderIndex = (request, reply) => {
  [...]
  reply.view('serverSideIndex') // serverSideIndex is a .pug template
}

Here I'm using reply.view to directly respond with a rendered view to the client. I need to inject caching logic here instead however, in order to not render more often than necessary and thereby optimize performance.

Let me know if I need to provide more code.

Regarding how to render a view into a serialized representation, it's done through the request.render method:

let renderedView = request.render('serverSideIndex')

As for responding with this serialized rendering back to the client, it's simply done by passing it to the reply function:

reply(renderedView)
