setup a pinia store with setters and getters in a vue plugin that does not have any ui components in typescript

To set up a Pinia store with setters and getters in a Vue plugin without any UI components, you can follow these steps:

  1. First, create a new file for your store. This file should export a defineStore function that creates the Pinia store instance. Here's an example:
index.ts
import { defineStore } from 'pinia'

export const useMyStore = defineStore({
  id: 'myStore',
  state: () => ({
    foo: 'bar',
  }),
  getters: {
    getFoo() {
      return this.foo
    },
  },
  actions: {
    setFoo(value: string) {
      this.foo = value
    },
  },
})

  1. Next, create a plugin that registers the Pinia store instance. The plugin should import the store instance and call app.use to install it into the Vue app. Here's an example:
index.ts
import { App } from 'vue'
import { createPinia } from 'pinia'
import { useMyStore } from './myStore'

export const setupPinia = (app: App) => {
  const pinia = createPinia()
  app.use(pinia)
  pinia.store.useStore(useMyStore)
}

  1. Finally, in your main Vue app file (e.g. main.ts), import the plugin and call it to install the Pinia store:
index.ts
import { createApp } from 'vue'
import { setupPinia } from './plugins/pinia'

const app = createApp(...)
setupPinia(app)
...

With these steps, you should now have a Pinia store with setters and getters that can be used throughout your Vue app.
