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?

Myself has read above and implemented a solution. could help you as well!!

All objects stored in Vue act as an observable. So if reference of a value is changed/mutated it triggers the actual value to be changed too.

So, Inorder to reset the state the initial store modules has to be copied as a value.

On logging out of an user, the same value has to be assigned for each modules as a copy.

This can be achieved as following:

Step 1: Create a copy of your initial module.

// store.ts

// Initial store with modules as an object
export const initialStoreModules = {
    user,
    recruitment,
};

export default new Vuex.Store({
    /**
     * Assign the modules to the store 
     * using lodash deepClone to avoid changing the initial store module values
     */
    modules: _.cloneDeep(initialStoreModules),
    mutations: {
        // reset default state modules by looping around the initialStoreModules
        [types.RESET_STATE](state: any) {
        _.forOwn(initialStoreModules, (value: IModule, key: string) => {
            state[key] = _.cloneDeep(value.state);
        });
        },
    }
});

Step 2: Call the action to mutate the state to initial state.

// user_action.ts
const logout = ({ commit }: any) => {
    commit(types.LOGOUT_INIT);
    new UserProxy().logout().then((response: any) => {
      router.push({
        name: 'login',
      });
      // reset the state
      commit(types.RESET_STATE);
    }).catch((err: any) => {
      commit(types.LOGOUT_FAIL, err);
    });
};
