The renderer class

This class is exporting a connect middleware which handles and serves all SSR and asset requests.

Hooks

We can register hooks on certain life cycle events.

Hook	Arguments	When
`render:before`	(renderer, options)	Before setting up middleware and resources for the Renderer class, useful to overload some methods or options.
`render:setupMiddleware`	(app) connect instance	Before Nuxt adds its middleware stack. We can use it to register custom server side middleware.
`render:errorMiddleware`	(app) connect instance	Before adding Nuxt error middleware, useful to add your own middleware before using Nuxt's. See the Sentry module for more info.
`render:resourcesLoaded`	(resources)	Called after resources for renderer are loaded (client manifest, server bundle, etc).
`render:done`	(renderer)	SSR Middleware and all resources are ready (Renderer ready)
`render:routeContext`	(context.nuxt)	Every time a route is server-rendered and before `render:route` hook. Called before serializing Nuxt context into `window.__NUXT__`, useful to add some data that you can fetch on client-side.
`render:route`	(url, result, context)	Every time a route is server-rendered. Called before sending back the request to the browser.
`render:routeDone`	(url, result, context)	Every time a route is server-rendered. Called after the response has been sent to the browser.
