Change another module state from one module in Vuex

Question

I have two modules in my vuex store.

var store = new Vuex.Store({
    modules: {
        loading: loading 
        posts: posts
    }
});

In the module loading, I have a property saving which can be set either true or false and also have a mutation function named TOGGLE_SAVING to set this property.

In the module posts, before and after fetching posts, I want to change the property saving. I am doing it by calling commit('TOGGLE_SAVING') from one of the actions in the posts module.

var getPosts = function (context) {
    context.commit(TOGGLE_LOADING);
};

When it tried to commit, I got following error in the console

[vuex] unknown local mutation type: TOGGLE_LOADING, global type: posts/TOGGLE_LOADING

How can I mutate state in another module using commit?

Answer

Try it with following parameters as suggested here;

commit('TOGGLE_LOADING', null, { root: true })

If you have namespaced set to true (in Nuxt that's the default when in modules mode), this becomes:

commit('loading/TOGGLE_LOADING', null, { root: true })
#vue.js
