How to perform the following command using gtag ?

[patrickmonteiro]

I need to run:

dataLayer.push({ ecommerce: null });

But I still don't understand how to do this with gtag. Would it be an event?

To add values to the dataLayer property of the global window scope, you can use useGtag as follows:

// Can be used on the server and client-side, but will only have an effect in the client
const { gtag } = useGtag()
gtag({ ecommerce: null })

Under the hood, the extracted gtag function will add properties to dataLayer. For reference, see:

nuxt-gtag/src/runtime/gtag.ts

Line 2 in 1af82b9

export function gtag(command: string, ...args: any[]) {

I hope that helps you going forward.
