An easy way to use anything you need/want as a key to a hash.
The npm module name used to be hashtable, but I renamed it because someone else requested to use it and I haven't updated this project in a couple years.
$ npm install js-hashtable
There are two classes for your hashtable pleasure:
QHash stands for "quick hash". It's primary advantage is that it is light and fast.
not check to see if two keys are similar enough to be declared equal (for the most part). Therefore,
if you pass in an object as a key, only that object will be able to retrieve the value. In this way,
QHash offers more security than
var bob, hash, apiKey; bob = new Person('Bob'); apiKey = new SomeLongUniqueThing(); apiKeys = new QHash(); apiKeys.set(bob, apiKey); // -> apiKey apiKeys.get(bob); // -> apiKey apiKeys.set(bob, null); // -> null apiKeys.remove(bob); // -> null apiKeys.get(bob); // -> undefined
This hash will convert all keys passed in to a string. Objects with the same properties in different orders will generate the same strings. Therefore, the object does not have to be exactly the same in order to retrieve the value, but instead must share all the same information. Inherited values will not be accounted for.
HashTable supports the
remove functions, but we now have a little
var routes, hkey = Hash.key; routes = new Hash(); // Define a route in your routes hash routes.set(/^\/user\/all(\.json)?$/, UsersController.displayAll); // Two ways to do the same thing routes[hkey( /^\/user\/(\d*)$/ )] = UsersController.displayById;
