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:

• cache corresponds to the cache name for response caches. Uses the server's default if not given.
• enabled whether to enable caching on the endpoint. Defaults to true, meaning all viable (see above) endpoints will be cached.
• digest defaults to djb2, this is the algorithm used to digest the request for caching purposes. Other available options are: md5, sha1, sha256, sha512, ripemd160.
• segment is the Catbox cache segment to store in. Defaults to routebox
• wasCachedHeader header that gets sent down when we serve a cached response. Defaults to X-Was-Cached.
• parse configures which parts of the request will be used to form the cache key:
  • query whether to include the query string. Defaults to true.
  • method whether to include the request method. Defaults to true.
  • path whether to include the route path. Defaults to true.
• callbacks provides 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 call reply.continue(). These are called at the onPreResponse lifecycle point.
  • onCacheHit is called when a cached page is served.
  • onCacheMiss is called when a page that could be cached but is not (yet) is served.
  • auth will skip caching if a user has been authenticated. Defaults to false, meaning always cache regardless of whether there is a request.auth object.

In addition there is one other setting that can be specified only in config.plugins.routebox:

• pluginCache can be used to set cache options instead of config.cache. So caching works as specified by config.plugins.routebox.pluginCache, but cache-control directives aren't sent out to the browser. If there's an endpoint that can sometimes provide private data, you can call request.nocache() to prevent Routebox from caching the request.
