is it the problem of my node version?
I'd suggest using nvm to pop down to 0.10 for a quick test
I'll tell you my findings.
not sure why
that's fine, just check streaming logic
supposedly fixed by joyent/node@f2b297c
yes
@brian-gates cannot hold on, its 5 am at Singapore. I need a sleep now. talk to you later.
Is there a way to provide username and password with cypher-stream?
@brian-gates hi again! I noticed that if you make a Cypher query, that doesn't return anything at all from the db, the whole application freezes. For example If you want to check that something exists, and it doesn't, if you use "MATCH" neo4j doesn't return anything at all, in that case the ").on('data' " function waits forever, as far as I can tell, and the whole app freezes. I had to use "OPTIONAL MATCH" which returns "null" if there is no match to avoid this problem.
I'm a beginner so maybe my code is constructed in a bad way, but just wanted to mention this :)
Will try with promises
@brian-gates , where do you submit these? : D

I'm becoming more educated on JS, and it seems that the problem is with how I structured my code. Not 100% sure yet, but I think I'm doing things in a Sync way, not Async.
So I'm not sure if submitting this will have any use.
I'm not using "callbacks" in my code so it's pretty obvious to me now that It will block the entire app if it gets stuck on some part of the code.
Thus when I send a Cypher query to Neo4j and the flow of the app depends on the result of that query, and the query doesn't return a thing because "Match" doesn't return any data if it fails to find anything, the whole app sits and waits for the .on('data') which never comes : )
I guess if I use Async code the app will continue to do other things and not completely freeze with no errors
My code is literally "if (something) { var query= 'the query'; cypher-stream(query).on('data', function(result){ do stuff with result});"
I posted a git issue, which I'll be happy to close if theres a simple solution
