[Question] Can 'useGA4React' hook be used for sub-domains as well ?

[mahesh-chotrani]

While going through GA documentation, they do support multiple sub domains for which events can be recorded.

We have multiple domains (one for each customer, a.example.com, b.example.com, etc. ), and we want to roll up the data collected. This is in addition to per customer data collection.

I tried the same using the below example

const Example = () => {
  const ga4React1 = useGA4React('GA_CODE_I', {}, []); // GA CODE, optional, if empty try to get from globals
  console.log(ga4React1);
  . . .
  const ga4React2 = useGA4React('GA_CODE_II', {}, []); // GA CODE, optional, if empty try to get from globals
  console.log(ga4React2);
  . . .
  return <>{JSON.stringify(ga4React)}</>;
};

But the second object always found to be null. Is there anything missed out in above configuration ?

I have not particularly tested this use, so if you find any problems, report them to me that I correct it, but I suggest you try this:

const ga = useGA4React("G-1JXXXXX,G-2JXXXXX");

or

const ga = useGA4React(["G-1JXXXXX","G-2JXXXXX"]);

and then to do that. you have to use the function directly gtag
