Hi everyone, As an exercise to learn node.js, I propossed myself to write a module to connect node.js with a Neo4j database. My problem is in how to design the module.
Neo4j is a graph database, so it basicaly has nodes and relationships between nodes. Its interface is based on a RESTful protocol. These are issues are facing when writing the module: - *Callbacks or to emit an event?* The module should have access to operate over nodes and relationships. These operations should be asynchronous. Should the operations recieve a callback or emit an event? or both? - *Operations on nodes* Let's say there is a operation to add a node like: addNode(properties); Every node in the database has a unique id. When adding a new node to the database returns a JSON with all the information about the operation (including the id). Using the id, afterwards I could perform some modify operations on the node. The database has a REST message to modify a node and you have to indicate the identificator. There is two options: - The addNode operations returns in the callback or in the event the reponse from the database. So, the user could extract the id from this information and perform a modify(id,property,newvalue). - The addNode operation returns a Node object. Then on this object you can perform operations like: var x = addNode(properties); x.modify(property, newvalue); Thanks in advance -- Job Board: http://jobs.nodejs.org/ Posting guidelines: https://github.com/joyent/node/wiki/Mailing-List-Posting-Guidelines You received this message because you are subscribed to the Google Groups "nodejs" group.
