QUESTION
I've been working on a project that used d3 v5.5.0, moved it to another computer, and when I did npm install it now acts as if it's a higher version of d3?
Part of my program relies on the old way of d3 calling transform for zoom, and worked when it was that version. Yet even though in my packages it says it's got 5.5.0, it's throwing errors that event.transform was deprecated (Which happened in v6). How would it know it's deprecated if it should still be using 5.5.0? Also, if I do npm list
it says the version of d3@^5.16.0? Which even then that doesn't make sense as you can see from my package.json.
Here is my package.json
...ANSWER
Answered 2021-Nov-11 at 22:32In your package.json
, you have specified d3 to be "^5.5.0"
. The ^
there says that the version to install must be at least version 5.5.0, so npm just installs the latest. If you want to force v5.5.0, you should specify it withput the ^
.
so your package.json should have "d3": "5.5.0"
instead of "d3": "^5.5.0"

I wanted to configure a neo4j database attached to the application. I decided to use the use-neo4j

QUESTION
I am loading data in from a Neo4J database using use-neo4j and have created a custom hook. It makes a query to the database and then converts the data to a format I can use for plotting the data.
It is a lot of code but basically neo4jToJSON
converts the data from Neo4J, then I set it to the state, lastly I return the state to be used in other components.
Note:
Before this I was just returning neo4jToJSON
and had no issues. But the moment I incorporate state into the function and return the state it throws this error.
Edit:
I have tried the suggested answer in the updated code below but now the data just returns undefined.
