Usage:
|
|
|
|
|
|
|
|
|
|
var LRU = require("lru-cache")
|
|
|
|
|
, cache = LRU(10, // max length. default = Infinity
|
|
|
|
|
|
|
|
|
|
// calculate how "big" each item is
|
|
|
|
|
//
|
|
|
|
|
// defaults to function(){return 1}, ie, just limit
|
|
|
|
|
// the item count, without any knowledge as to their
|
|
|
|
|
// relative size.
|
|
|
|
|
function (item) { return item.length },
|
|
|
|
|
|
|
|
|
|
// maxAge in ms
|
|
|
|
|
// defaults to infinite
|
|
|
|
|
// items are not pre-emptively pruned, but they
|
|
|
|
|
// are deleted when fetched if they're too old.
|
|
|
|
|
1000 * 60)
|
|
|
|
|
|
|
|
|
|
cache.set("key", "value")
|
|
|
|
|
cache.get("key") // "value"
|
|
|
|
|
|
|
|
|
|
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.
