LocalCache middleware

Caches results of queries in memory returning the previous result of repeated queries until the entry expires. Entries are cached based on the query used.

Config options:

interval: The interval in seconds that a given cache entry will be considered fresh
max_entry_size: Max len of results that will be cached. If set only results less than this value will be stored in the cache. All others will be refetched every time.

Importing this module adds the fresh query option to Relation. This allows the developer to easily force a query to be fresh:

   # This query will always fetch fresh data
   Person.where({ 'name': 'bob' }).fresh()
