In the structure of my components, the SideHead component contains a method that needs to access objects of Incidents and call functions on them. Simply put, I want a method in "A" to access objects of "B" and invoke their methods. I've considered emitting an event and propagating it as a potential solution, but I haven't been able to successfully implement it. Any suggestions or ideas on how to achieve this?
Utilize tools for state management like Vuex to facilitate communication between components that are not directly connected as parent and child.
Relying on emitting events to $root or an event bus can be unreliable, prone to race conditions, and hard to diagnose - issues with event captures may go unnoticed. For example, you may never receive notification if an event fails to be captured.
1) Make sure to include a reference tag for each component.
<app ref="App">,
<index ref="Index">,
<incidents ref="Incidents"><incident-by-prio ref="IncidentByPrio">Then, access them from the root A component using this method:
this.$root.$refs.App.$refs.Index.$refs.Incidents.$refs.IncidentsByPrio.SomeMethod()Edit 1:
2) Trigger an event from Component A at the root level.
Component A
this.$root.$emit('SomeEvent', {...});Handle this event in your desired component:
this.$root.$on('SomeEvent', () => {...});Is there a way to wrap my top-level page _app.js in both Redux provider and Next-auth provider? Currently, I have already wrapped it in the Next-auth provider like this: import React from "react" import { Provider } from 'next-auth/client&ap ...
