direct-vuex

direct-vuex

Just Vuex with typing. Compatible with the Vue 3 composition API.

How to use

Install

First, add direct-vuex to a Vue application:

npm install direct-vuex

Create the store

The store is implemented in the same way as usual (ie. without typing). However, it is necessary to append as const at the end of store and module implementation objects. It will help direct-vuex to better infer types.

Create the store:

import Vue from "vue"
import Vuex from "vuex"
import { createDirectStore } from "direct-vuex"

Vue.use(Vuex)

const store = createDirectStore({
  // … store implementation here …
} as const)

export default store
export type AppStore = typeof store

declare module "vuex" {
  interface Store<S> {
    direct: AppStore
  }
}

The classic Vuex store is still accessible through the store.original property. We need it to initialize the Vue application:

import Vue from "vue"
import store from "./store"

new Vue({
  store: store.original, // Inject the classic Vuex store
  // …
}).$mount("#app")

Use typed wrappers from outside the store

From a component, the direct store is accessible through the direct property of the classic store:

const store = this.$store.direct

Or, you can just import it:

import store from "./store"

Then, the old way to call an action:

store.dispatch("myModule/myAction", myPayload)

… is replaced by the following wrapper:

store.dispatch.myModule.myAction(myPayload)

… which is fully typed.

Typed getters and mutations are accessible the same way:

store.getters.myModule.myGetter
store.commit.myModule.myMutation(myPayload)

Notice: The underlying Vuex store can be used simultaneously if you wish, through the injected this.$store or store.original.

Limitations

• Actions can't be declared with the object alternative syntax.
