To create an instance of the DocumentStore you need to specify a list of URL addresses that point to RavenDB server nodes.
{CODE:nodejs document_store_ctor@client-api\creatingDocumentStore.js /}
{WARNING:Important}
Do not open a DocumentStore using URL addresses that point to nodes outside your cluster.
{WARNING/}
{CODE:nodejs document_store_creation@client-api\creatingDocumentStore.js /}
The above snippet is going to instantiate a communication channel between your application and the local RavenDB server instance.
##Initialization
A DocumentStore instance must be initialized before use by calling the .initialize() method.
{NOTE:Conventions}
After DocumentStore initialization, the conventions are frozen - modification attempts are going to result with error. Conventions need to be set before .initialize() is called.
{NOTE/}
##Singleton
Because the document store is a heavyweight object, there should only be one instance created per application (a singleton - simple to achieve in Node.js by wrapping it in a module). Typical initialization of a document store looks as follows:
{CODE:nodejs document_store_holder@client-api\creatingDocumentStore.js /}
{NOTE If you use more than one instance of DocumentStore, you should dispose it after use by calling its .dispose() method. /}
