ViewsInvalid Hook Call use-neo4j
I recently started building a react app.
I wanted to configure a neo4j database attached to the application. I decided to use the use-neo4j hook. I followed the basic step of creating the driver instance like this:
import React from "react";
import ReactDOM from "react-dom";
import "./css/index.css";
import App from "./js/App";
import Nav from "./js/Nav";
import { Neo4jProvider, createDriver } from "use-neo4j";
const driver = createDriver("neo4j", "localhost", 7687, "lode", "neo4j");
ReactDOM.render(
<React.StrictMode>
<Neo4jProvider driver={driver}>
<Nav />
<App />
</Neo4jProvider>
</React.StrictMode>,
document.getElementById("root")
);
But I ended up having the Invalid Hook Call error.
Except if I remove the Neo4jProvider tags

I tried everything I can to fix it, I'm pretty new at React. I would love someone to help me if they can.

Just like the error says, you can only call hooks inside the body of a functional component. So I would probably create a component that initiates the driver and returns the component that uses it -
import { Neo4jProvider, createDriver } from "use-neo4j";
const NeoProvider = ({ children }) => {
const driver = createDriver("neo4j", "localhost", 7687, "lode", "neo4j");
return (
<Neo4jProvider driver={driver}>
{children}
</Neo4jProvider>
);
}
And then import that at your top level and use that instead of the Neo4jProvider you're importing from the package.
