Improve Request Error Handling #62
Description
When a neo4j server is down for whatever reason, this module doesn't handle the ECONNREFUSED error- the entire node process exits, which makes it very difficult to return an error to the client. I'm working on a PR for this, but here's what I'm thinking of doing:
Change request callback arity from function(result) { to function(err, result) { This lets us catch ECONNREFUSED errors before they cause node to exit. I'll also have to handle the case where result is null in all functions that make HTTP requests.
