Async/Await with Vuex dispatch

You can not await a function without promise

await this.$store.dispatch('product/getProducts', 'bestseller');

This function return data or call new action

getProducts({commit}, type) {
    axios.get(`/api/products/${type}`)
        .then(res => {
            let products = res.data;
            commit('SET_PRODUCTS', {products, type})
        }).catch(err => {
        console.log(err);
    })
},

And this function return promise because of async function

async function return promise

async getProducts({commit}, type) {
    let res = await axios.get(`/api/products/${type}`);

    commit('SET_PRODUCTS', {products: res.data, type});

}

Now using above function now you can use

await this.$store.dispatch('product/getProducts', 'bestseller');

with await key word Or you can return axios because axios also return a promise.

Change this:

getProducts({commit}, type) {
    axios.get(`/api/products/${type}`)
        .then(res => {
            let products = res.data;
            commit('SET_PRODUCTS', {products, type})
        }).catch(err => {
        console.log(err);
    })
},

To this:

getProducts({commit}, type) {
    return axios.get(`/api/products/${type}`)
        .then(res => {
            let products = res.data;
            commit('SET_PRODUCTS', {products, type})
        }).catch(err => {
        console.log(err);
    })
},

Should work.

axios.get returns a promise. You would need to return that promise in order to let await wait for it. Otherwise, you are implicitly returning undefined and await undefined would immediately resolve.
