es-cache

A simple in-memory cache on ecmascript 6 and typescript.

Installation

npm install es-cache

Usage

var Cache = require('es-cache');
var cache = new Cache();

// now just use the cache

cache.put('foo', 'bar');
console.log(cache.get('foo'))

// that wasn't too interesting, here's the good part

cache.put('houdini', 'disappear', 100) // Time in ms
console.log('Houdini will now ' + cache.get('houdini'));

setTimeout(function() {
  console.log('Houdini is ' + cache.get('houdini'));
}, 200);

which should print

bar
Houdini will now disappear
Houdini is null

API

put = function(key, value, time, callback)

• Simply stores a value
• If value is a function then function returned value is cached.
• If time isn't passed in, it is stored forever
• If time is passed then value is refreshed after the specified time using the specified function. Will actually remove the value in the specified time in ms (via setTimeout)
• executes the callback function when value is removed.
• Returns the cached value

get = function(key)

• Retrieves a value for a given key
• If value isn't cached, returns null

del = function(key)

• Deletes a key, returns a boolean specifying whether or not the key was deleted

clear = function()

• Deletes all keys

size = function()

• Returns the current number of entries in the cache

keys = function()

• Returns all the cache keys
