The way I remember Neo4j from prior versions is that could change the style of nodes and relationships in the Neo4j browser by clicking such element and then using the UI to select size of node, color, what property to use for the label etc.
I have access to the :style command, which spits out the GraSS file, which I can modify locally and reupload but this is a very unfriendly experience.

I cannot get APOC to work on neo4j.
Documentation is good ... when present!
I installed the apoc library via Neo4j Desktop:
Launch Neo4j Desktop
Locate DBMS
Select Plugins tab on right
installed the plugin
Then I open a project.
I try:
CALL apoc.load.json("file:///person.json")
YIELD value
RETURN value;
but
There is no procedure with the name `apoc.load.json` registered for this database instance. Please ensure you've spelled the procedure name correctly and that the procedure is properly deployed.
Indeed The available procedures does not display apoc, in spite it is installed.
Then, after I cleared out that Neo4j Desktop is not using the installed community edition I had, and found that i can find the installed versions under the "more" options > Terminal:
I checked that my neoj4.conf file have these lines:
# Leaving this unconfigured will load all procedures found.
#dbms.security.procedures.allowlist=apoc.coll.*,apoc.load.*,gds.*
(commented out, to load everything, so apoc should load...)
I think I have done OK, as here:
APOC installation neo4j desktop
I also tried to delete the project and set it up again:

but still not working...

How do I get APOC to work ??
Do I have to install it for each project ?
Do I need to configure it for each DB in the project ?
I am using neo4j desktop 1.5.6.
#Edited
today I replicated steps of yesterday, paying attention to the recommendations of #William Lion answer.
At launch of neo4j Desktop, I was prompted an alert that "Local graph password has been changed".
That is strange, because I have not changed it...
It did not accept nor my previous password (the one I use for the server), nor the default 'neo4j', but could pass the alert because I could ignore this change until the next Graph start.
So I ignored it, and was prompted to enter the password to connect with the neo4j server. And this time, apoc were found.
I tried to close the neo4j desktop, quitting from all open projects, and relaunch. This time I was not asked to input the password for the local dbms. So, I assumed the to have restarted the next Graph, following the previous alert, and I was expected to be requested to input the password again.
Maybe the problem was here. So, to avoid future hiccups:
does neo4j reset the password of local dbms itself after a while or after certain conditions ?
after neo4j desktop closes, am I sure all server and open dmbs instances are properly shut down ? What does until the next Graph start actually mean ?
Plugins must be installed for each DBMS instance in Neo4j Desktop (there can be multiple DBMS instances in each project). Also, there can only be one active DBMS in Neo4j Desktop at a given time. Make sure that you have installed the plugin for the DBMS instance that you want to work with AND that DBMS is the one that is currently running. I'm guessing that you successfully installed the plugin for one DBMS, but tried querying with a different active DBMS that did not have the plugin.
I am trying to edit the settings of my AuraDB hosted neo4j instance, specifically, trying to set the following line:
apoc.import.file.enabled=true
I have looked at the official tutorial and many other places, and for the life of me, I am not able to find out where either the "settings" button is located, or how to locate the neo4j.conf or apoc.conf files. It seems that something has possibly changed in a newer version. I have tried both in the browser at https://console.neo4j.io/#databases and in Neo4J Desktop. For the desktop application, I am running it on Ubuntu via the .appimage. I created my database on the website and connected via remote connection following this guide.
Some things that might help me solve the issue:
Is it possible to open a shell in auradb to let me run normal bash commands?
Is the .conf accessible "within" the .appimage?
From the official description of File locations, I am supposedly able to do the following in Neo4j Desktop to find the configuration file:
From the Open dropdown menu of your Neo4j instance, select Terminal,
and navigate to /conf/neo4j.conf.
Yet, when I press the Open dropdown menu, I do not see a Terminal option. What I get is Neo4j Browser, Neo4j Bloom, and Neo4j ETL Tool.
Aura is a managed database - which is to say that you don't get low-level access to configuration of the kind you're describing. The documentation you're looking at relates to self-hosted instances of Neo4j, where you're the one managing and configuring the instance from scratch and where you have that level of access to the underlying configuration.
To the problem you're trying to solve, the following article entitled Loading data into Neo4j Aura is your best bet for the currently available options for loading data into your managed database.
Per the documentation, APOC is installed in Aura databases, but only a limited set of functions and procedures are enabled (as of May 2022). In particular, only a small subset of apoc.import procedures are available - from what I can see, CSV and GraphML support is enabled via apoc.load.csv and apoc.load.graphml, while you also have access to apoc.load.json and apoc.load.xml.
Lists of the currently supported procedures and functions are available at the foot of that document:
Neo4j Aura Supported APOC procedures (updated).json
Neo4j Aura Supported APOC functions (updated).json
From a Neo4j Aura Knowledge Article:
In Aura, we currently do not support changing any property that may
exist in the Neo4j product and defined in neo4j.conf.
I'm using Neo4j Desktop Version 1.4.3. I've created a new project named "Yelp Project", then uploaded the yelp dump file in it, but I'm not getting the option "Create new DBMS from dump". So I selected Add --> Local DBMS and created a database. But when I open Neo4j Browser, there are no nodes and relationships. I'm not able to figure out how to get this done, can someone help refer image
The feature that you are looking for is not yet available for Neo4j desktop Windows version. See below community thread discussion then scroll at the bottom.

I would like to display icons within nodes of Neo4j web browser by using this repo: https://github.com/graphadvantage/neo4j-browser-icons/ but I can't make it work.
Could you help with the installation? (I'm using docker image of Neo4j 3.5)
You can use post_connect_cmd to set the style from the grass file that is available in the above GitHub repo.
No need to run the Cyphers, using the existing grass file will work.
For using above grass file you need to modify the neo4j.conf to whitelist the domain or allow CORS and add the post_connect_cmd to set the style:
Add the following lines at the end of the neo4j.conf file and restart the Neo4j.
#********************************************************************
# Custom Styling for Neo4j Browser
#********************************************************************
browser.remote_content_hostname_whitelist=github.com,githubusercontent.com
browser.post_connect_cmd=style https://raw.githubusercontent.com/graphadvantage/neo4j-browser-icons/master/graphstyle.grass
This works for me. You can verify by creating a node:
CREATE(n:Upload{name:'Upload'}) return n
I have developed a default style for my network that I would like to automatically apply to all Neo4j Browser instances. The style is specified using a GRASS (graph-style-sheet) file. I read in the 3.0.1 changelog that you can apply a style from a URL with the :style browser command. However, is it possible to configure a Neo4j server with a default GRASS?
I'm using Neo4j 3.0.1. If a custom default style is not possible, are then any workarounds so users so users don't have to mess with any styling commands?
