Ask: How to catergorize a event?

[NicolasPrr]

Is there a way to categorize a event? What is the function of instanceName prop?

This is passed to Amplitude and allows you to set the Amplitude instance name. useful if you're running multiple tracking instances on the same site. From their docs.

Logging Events to Multiple Amplitude Apps

If you want to log events to multiple Amplitude apps, you will need to have separate instances for each Amplitude app. As mentioned earlier, each instance will allow for completely independent apiKeys, userIds, deviceIds, and settings.

You need to assign a name to each Amplitude app / instance, and use that name consistently when fetching that instance to call functions. IMPORTANT: Once you have chosen a name for that instance you cannot change it. Every instance's data and settings are tied to its name, and you will need to continue using that instance name for all future versions of your app to maintain data continuity, so chose your instance names wisely. Note these names do not need to be the names of your apps in the Amplitude dashboards, but they need to remain consistent throughout your code. You also need to be sure that each instance is initialized with the correct apiKey.

Instance names must be nonnull and nonempty strings. Names are case-insensitive. You can fetch each instance by name by calling amplitude.getInstance('INSTANCE_NAME').

As mentioned before, each new instance created will have its own apiKey, userId, deviceId, and settings. You will have to reconfigure all the settings for each instance. This gives you the freedom to have different settings for each instance.
