lru-diskcache


A disk cache object that deletes the least-recently-used items. Based on lru-cache.

``js
var LRU = require("lru-diskcache")

var cache = LRU('./cache', {
max: 50
});

cache.init()

cache.set("myfile.md", "A string content")
cache.get("file").then(function() { ... }) // Buffer("A string content")

// with a buffer or stream
cache.set("image.png", new Buffer([ ... ]))
cache.set("index.html", request.get("https://www.google.fr"))

cache.reset() // empty the cache
`

If you put more stuff in it, then items will fall out.

If you try to put an oversized thing in it, then it'll fall out right away.

$3

`js
// Initialize the cache
cache.init()

// Get content as a buffer (return a promise)
cache.get(key)

// Get content as a string
cache.get(key, { encoding: 'utf8' })

// Get content as a stream (return a promise)
cache.getStream(key)

// Check if a key is in the cache, without updating the recent-ness or deleting it for being stale.
cache.has(key)

// Delete a key from the cache
cache.del(key)

// Return total length of objects in cache taking into account
cache.size()

// Manually iterates over the entire cache proactively pruning old entries
cache.prune()
