Transparent catbox-based response caching for Hapi servers
Readme
Routebox
Routebox integrates with catbox to provide transparent route-level caching. It can work with zero configuration changes on your server.
Usage
To Routebox, simply register it on your server.
server.register(require('routebox'), function (err) {
// ...
});By default, all endpoints with the cache configured in their route options and privacy set to public (or omitted; public is the default) will be cached. Routebox automatically hooks in to the expiresAt, expiresIn, and statuses options of the caching config.
These options are available when routebox is registered and can also be overridden on a per-route basis by passing in config.plugins.routebox:
cachecorresponds to the cache name for response caches. Uses the server's default if not given.lruwhen set, allows responses to be cached in-memory in addition to the catbox cache.

callbacksprovides touch-points you can use to intercept the request and gather metrics. Each callback functions like a Hapi extension, taking the(request, reply)as arguments, after which you should callreply.continue(). These are called at theonPreResponselifecycle point.onCacheHitis called when a cached page is served.onCacheMissis called when a page that could be cached but is not (yet) is served.
If there's an endpoint that can sometimes provide private data, you can call request.nocache() to prevent Routebox from caching the request.
