I'm on Nuxtjs 2.13 and i wanna know "how should I remove event listeners (is there a need??)".
I'm not talkinkg about js addEventListener and removeEventListener . I'm more curious about this.$emit() , $nuxt.$emit() and $nuxt.$on() . is there a way to remove $nuxt.$on() or listener on component <mycomp @myevent="do()" /> in beforeDestroy() and is it necessary?
as my Nuxt project using so much RAM on my server, i kindda think there are some optimization needed.
https://v3.vuejs.org/api/options-lifecycle-hooks.html#unmounted
When this hook (unmounted - OP) is called, all directives of the component instance have been unbound, all event listeners have been removed, and all child component instance have also been unmounted.
However, there is vm.$off which can
Remove custom event listener(s). https://v2.vuejs.org/v2/api/#vm-off
I saw it used here in a Nuxt context to remove $nuxt.$on listeners:

So, if need be, use $nuxt.$off to remove custom events in Nuxt.
