uber-cache-namespace — Wrapper for uber-cache providing namespacing

Installation

npm install uber-cache-namespace

Usage

uber-cache-namespace prevents accidental overriding of data when more than one application uses the same cache engine (eg. memcached)

var cache = new UberCacheNamespace('my-namespace', myUberCacheEngine)

cache.set('some-key', someData, ttl, function (err, savedValue) {
	// writes to myUberCacheEngine with my-namespace- prefixed to the key
	cache.get('some-key', function (error, data) {
		// retrieves data — you don’t have to worry about the prefix
	}
})

cache.on('miss', function (key) {
	// key will not have the prefix prepended
})

API

Functions

• set(key, value, ttl, callback)

  ttl milliseconds until expiry. Optional

• get(key, callback)

• delete(key, callback)

Please be aware that although some uber-cache engines support dump, size, and clear, uber-cache-namespace does not. These methods are implemented only to make testing possible.

Events

• miss(key) — Emitted when a get(key) fails to find a valid cached item with that key.
• hit(key, value, ttl) — Emitted when a get(key) finds a valid item in the cache.
• stale(key, value, ttl) — Emitted when a get(key) can’t find a valid item but a stale item still exists.
• delete(key) — Emitted when a delete(key) deletes an item.
