How to use @casl/vue with pinia

I'm currently using @casl/ability with Vue 3 but I can't figure out how to make it work with Pinia.

Here's what my app.js looks like:

import { createApp } from "vue"
const app = createApp({})

// pinia
import pinia from "./store"
app.use(pinia)

// casl
import { abilitiesPlugin } from "@casl/vue"
import ability from "./cacl/ability"
app.use(abilitiesPlugin, ability, {
    useGlobalProperties: true
})

// ...

app.mount('#app')

And here's what my ability.js looks like:

import { defineAbility } from "@casl/ability"
import { useMainStore } from "../store/main"

const ability = defineAbility((can, cannot) => {
    const store = useMainStore()
    if (store.user.role === "admin") {
        can("read", "Post")
    }
    // ...
})

export default ability

And I'm getting this error: enter image description here

I've checked Pinia's documentation about Using a store outside of a component but I'm not quite sure what I am doing wrong here? (P.S. Pinia is working as expected for the rest of my project. I'm just not sure how to make it work here.)

maybe you better define rules in pinia. To use ability there you have to make it available inside the store (similar to vue-router):

main.js:

import { abilitiesPlugin } from "@casl/vue";
import { createMongoAbility } from "@casl/ability";

const ability = createMongoAbility();
app.use(abilitiesPlugin, ability);
pinia.use(({ store }) => {
  store.ability = markRaw(ability);
});

In store.js you are able to access ability now like this:

actions: {
  initCasl() {
    const builder = new AbilityBuilder(this.ability);
    if (this.user.role === "admin") {
      builder.can("read", "Post")
    }
    this.ability.update(builder.rules);
  }
}
