I would also like to bring up my difficulties to try out a modified version of
I get the following error: It seems that running When I point the package How am I supposed to try out this library in a local project? What did work was to point the # in package.json of `neo4j-graphql-js`

...How do you setup this library for local development? |

For development, I use Building the library locally and importing locally I believe has also worked for me. The issue here is that For running all tests locally, run a local neo4j instance with this database loaded with username (as mentioned in #248 we need to improve / document this process better) |

@johnymontana thanks a lot for pointing out the necessary steps. I was able to import the database locally. Oddly, plenty of integration tests fail: Terminal outputrobert@e480 ~/D/neo4j-graphql-js> git status

@roschaefer all tests should be passing. Some of the integration tests modify the database so each test run needs to start with a fresh version of the database. |

At the moment, it's not quite clear to me how to run the tests locally. I will let the build server run the tests for now and I hope to see some tests failing that would give me some direction. @johnymontana @jexp @michaeldgraham I would be very glad if you could help me out on how to run tests locally and what test cases you would expect to see. This commit is still work-in-progress.

Looks good to me. An additional test to cover the case where a @cypher directive field is requested in the selection set but not specified in the orderBy arg (and we still get the optimized ordering) would be nice, but not required for this PR as I think the basic functionality is covered here.

To be explicit - hasNoCypherDirective here applies to the orderBy field. We should still be able to use the optimized ordering if a @cypher field is requested in the selection set but not in the orderBy arg

Awesome - thanks @roschaefer! Sorry for the delay, we had a long holiday weekend in the US that pushed things back a bit. This should improve performance significantly for basic ordering cases. You say you are using this in production? Have you noticed a considerable performance improvement? Anything that is measurable? It would be nice to have some statistics for comparison, but we can at least backtest for comparison once we implement #240 And thanks for dealing with the janky test set up :-) |

@johnymontana great! Yes, we noticed a considerable performance improvement. There is a public holiday in Germany, too, and I am on my mobile. So I'll give you the exact stats later. But the difference was from ~30 down to 2 seconds on my laptop. Our small server on kubernetes just crashed before. I can send some more PRs to add the requested tests. Did you see me comments about the |

@mattwr18 @aonomike You must never `ORDER BY` a property with a `@cypher` directive. Reason: The order by performance will be terribly poor. See my issue: neo4j-graphql/neo4j-graphql-js#239 And my PR: neo4j-graphql/neo4j-graphql-js#247

Fix #239
First stab at improving order by performance …
At the moment, it's not quite clear to me how to run the tests locally.
I will let the build server run the tests for now and I hope to see some
tests failing that would give me some direction.
@johnymontana @jexp @michaeldgraham I would be very glad if you could
help me out on how to run tests locally and what test cases you would
expect to see.
This pull request is still work-in-progress.
