Nuxt await async + vuex

Im using nuxt and vuex. In vuex im getting data:

actions: {
    get_posts(ctx) {
      axios.get("http://vengdef.com/wp-json/wp/v2/posts").then(post => {
        let posts = post.data;


        if (!posts.length) return;

        let medias_list = "";
        posts.forEach(md => {
          medias_list += md.featured_media + ","
        });
        medias_list = medias_list.slice(0, -1);


        let author_list = "";
        posts.forEach(md => {
          author_list += md.author + ","
        });
        author_list = author_list.slice(0, -1);


        axios.all([
          axios.get("http://vengdef.com/wp-json/wp/v2/media?include=" + medias_list),
          axios.get("http://vengdef.com/wp-json/wp/v2/users?include=" + author_list),
          axios.get("http://vengdef.com/wp-json/wp/v2/categories"),
        ]).then(axios.spread((medias, authors, categories) => {

          ctx.commit("set_postlist", {medias, authors, categories} );

        })).catch((err) => {
          console.log(err)
        });


      })
    }
  },

In vuex state i have dynamic postlist from exaple below. How i can use it in Nuxt?

In nuxt i know async fetch and asyncData.

async fetch () {
    this.$store.dispatch("posts/get_posts");
}

Thats not working.

How i can say to nuxt, wait loading page, before vuex actions loading all data?

As you already mentioned there are:

  • fetch hook
  • asyncData

And differences are well described here

The reason why your code is not working might be in your store action. It should return a promise, try to add return before axios get method ->

get_posts(ctx) {
      return axios.get(...
    // ...

And then, on your page:

async fetch () {
    await this.$store.dispatch("posts/get_posts");
}

Also, in comment above you're saying that you dont want to commit data in store:

...load page only after vuex, i dont need to pass data in vuex

But you do it with this line:

ctx.commit("set_postlist", {medias, authors, categories} );

if you dont want to keep data in store, just replace line above with:

return Promise.resolve({ medias, authors, categories })

and get it on your page:

async fetch () {
    this.posts = await this.$store.dispatch("posts/get_posts");
    // now you can use posts in template 
}

Misread the actual question, hence the update

With Nuxt, you can either use asyncData(), the syntax will change a bit tho and the render will be totally blocked until all the calls are done.

Or use a combo of fetch() and some skeletons to make a smooth transition (aka not blocking the render), or a loader with the $fetchState.pending helper.

More info can be found here: https://nuxtjs.org/docs/2.x/features/data-fetching#the-fetch-hook

Older (irrelevant) answer

If you want to pass a param to your Vuex action, you can call it like this

async fetch () {
  await this.$store.dispatch('posts/get_posts', variableHere)
}

In Vuex, access it like

get_posts(ctx, variableHere) {

That you can then use down below.

PS: try to use async/await everywhere.

PS2: also, you can destructure the context directly with something like this

get_posts({ commit }, variableHere) {
  ...
  commit('set_postlist', {medias, authors, categories})
}
