How to clear state in vuex store?

Question

My state in vuex store is huge.

Is there a way to reset all the data in state in one go, instead of manually setting everything to null?

Answer 1

If you want to reset your entire state you can use the built in replaceState method.

Given a state set in index.js:

    const state = { user: '', token: '', products: [] /* etc. */ }
    const initialStateCopy = JSON.parse(JSON.stringify(state))

    export const store = new Vuex.Store({ state, /* getters, mutations, etc. */ })

    export function resetState() {
      store.replaceState(initialStateCopy)
    }

Then in your vue component (or anywhere) import resetState:

    import { resetState } from '@/store/index.js'

    // vue component usage, for example: logout
    {
      // ... data(), computed etc. omitted for brevity
      methods: {
        logout() { resetState() }
      }
    }
