node-hashtable
A simple hashtable written in node (not meant for production). It will help you share data over your node clusters or modules.
Installation
npm install node-hashtable
Example
With cluster:
var hashTable = ; var cluster = ; var numCPUs = length; ifclusterisMaster hashTable; // Fork workers. for var i = 0; i < numCPUs; i++ cluster; else ifclusterisWorker hashTable;
Without cluster:
var hashTable = ; hashTable; var data = hashTable; //In this case, callback is not required. console; //output -> "Hello World"
Verbs
hashTable.set("key", data, [callback])
This function will set data to a key. If your using a cluster, you should create the callback function!
hashTable.set("key", data, function(){
//Do stuff
});
hashTable.get("key", [callback])
This function will return data. In this case, if using with a cluster, you NEED to create the callback!
hashTable.get("key", function(data){
//Do stuff
});
hashTable.add("key", data, [callback])
Diferent from .set, this will append data to the key. Be carefull when appending objects.
hashTable.add("key", "more stuff", function(){
//Do stuff
});
hashTable.update("key", data, [callback])
This will find the property you want to update inside the key, and update it.
hashTable.update("key", {prop: 'new'}, function(){
//Do stuff
});
hashTable.delete("key", [callback])
No explanations needed...
hashTable.delete("key", function(){
//Do stuff
});
hashTable.createHash(data, [callback])
It will return a hash for your data.
hashTable.createHash(data, function(hash){
hashTable.set(hash, data, function(){
//Do stuff
});
});
hashTable.createKey(data, [callback])
It will return a random hash key.
hashTable.createKey(data, function(key){
hashTable.set(key, data, function(){
//Memo your key!
});
});
hashTable.clear([callback])
This function will clear the entire hash table.
hashTable.createKey(function(){
//Do stuff
});
