API

CachemanMemory()

Create cacheman-memory instance.

var cache = new CachemanMemory();

cache.set(key, value, [ttl, [fn]])

Stores or updates a value.

cache.set('foo', { a: 'bar' }, function (err, value) {
  if (err) throw err;
  console.log(value); //-> {a:'bar'}
});

Or add a TTL(Time To Live) in seconds like this:

// key will expire in 60 seconds
cache.set('foo', { a: 'bar' }, 60, function (err, value) {
  if (err) throw err;
  console.log(value); //-> {a:'bar'}
});

cache.get(key, fn)

Retrieves a value for a given key, if there is no value for the given key a null value will be returned.

cache.get(function (err, value) {
  if (err) throw err;
  console.log(value);
});

cache.del(key, [fn])

Deletes a key out of the cache.

cache.del('foo', function (err) {
  if (err) throw err;
  // foo was deleted
});

cache.clear([fn])

Clear the cache entirely, throwing away all values.

cache.clear(function (err) {
  if (err) throw err;
  // cache is now clear
});

cache.getAll([fn])

Get all keys and entries in cache

cache.set('foo', { a: 'bar' }, 60, function (err, value) {
  if (err) throw err;
  cache.getAll(function (err, data) {
    if (err) throw err;
  // [{ key: 'foo', data: { a: 'bar' } }]
});
