The equivalent for Vue 3 is Provide/Inject: https://vuejs.org/guide/components/provide-inject.html

Hi @matschik ,

Was trying to understand the goal of these code snippets. Could you give a bit more context (no pun intended) of what is the goal of this example?
From a Aurelia point of view, since it is class based, things can be done by using Dependency Injection. Another option is using the Event system. Using aurelia-store (i.e. RxJs state management) it is also possible.

Context VS Store (from Svelte link)

Contexts and Stores seem similar. They differ in that stores are available to any part of an app, while a context is only available to a component and its descendants. This can be helpful if you want to use several instances of a component without the state of one interfering with the state of the others.
In fact, you might use the two together.

Additionnally,store is planned for Component Party.

For Angular , Is it to good to mention service in this place? Yeah there is no such concept of context but using service we can eventually achieve that behavior.
