I have an application in nuxt that I want to connect to a websocket, I have seen examples where the callback to receive messages is placed inside a component, but I do not think ideal, I would like to place the callback inside my store, currently my code is something like this
//I'm using phoenix websocket
var ROOT_SOCKET = `wss://${URL}/socket`;
var socket = new Socket(ROOT_SOCKET);
socket.connect()
var chan = socket.channel(`connect:${guid}`);
chan.join();
console.log("esperando mensj");
chan.on("translate", payload => {
console.log(JSON.stringify(payload));
<store>.commit("loadTranslation",payload) //<- how can I access to my store?
})
chan.onError(err => console.log(`ERROR connecting!!! ${err}`));
const createStore = () => {
return new Vuex.Store({
state: {},
mutations:{
loadTranslation(state,payload){...}
},
....
})}
how can I access to my store inside my own store file and make a commit??? is it possible?...
I know there is a vuex plugin but I can't really understand well the documentation and I'll prefer build this without that plugin
https://vuex.vuejs.org/guide/plugins.html
thank you guys...hope you can help me...
You can do it in nuxt plugin https://nuxtjs.org/guide/plugins/
export default {
plugins: ['~/plugins/chat.js']
}
// chat.js
export default ({ store }) => {
your code that use store here
}

I'm trying to redirect to dashboard after login.
I found this in app.js file that
// make router instance available in store store.$router = router
So I codede that in my login method of auth.js file like below.
store.$router.push({ name: 'dashboard' })
But there is nothing to happen.
How can I use router in vuex store file?
Router is not available in the store directly. You might have to use plugin which makes the router available to the store.
Here is the Vuex-Router plugin which helps to access router to the store.
Are you trying to call router.push in an vuex action?
If so i am doing the same in my quasar v2 project
store/auth/actions.js
import { api } from 'boot/axios'
export function login({ dispatch, commit }, data) {
return api.post('/user/login', data).then(res => {
commit('setToken', res.data.token)
this.$router.push({ name: 'dashboard' }) // <-- What you are looking for?
}).catch(err => {
let msg = err.response.data || 'Error occurred'
return Promise.reject(msg)
})
}
I'm using the following code to dynamically create vue components. I'd like them to communicate with the vuex store but it looks like they have no access to it. Does anyone know how to solve this?
let module = this.modules.find(m => m.name === name)
const ModClass = Vue.extend(module.component);
const modInstance = new ModClass({
propsData: {
client: this.client,
}
});
modInstance.$mount();
modInstance.$on('close', () => {
modInstance.$destroy(true);
(modInstance.$el).remove();
})
this.$refs.panels.appendChild(modInstance.$el);
From the docs:
In order to have an access to this.$store property in your Vue components, you need to provide the created store to Vue instance.
Vuex has a mechanism to "inject" the store into all child components from the root component with the store option.
So, in your example this will be here:
const modInstance = new ModClass({
propsData: {
client: this.client,
},
store: yourVuexInstanceHere
});
Are you making a Nuxt plugin? If so, you can reach your store instance by deconstructing it from the context.
export default ({ app: { store } }, inject) => {
// your code...
const modInstance = new ModClass({
propsData: {
client: this.client,
},
store: store
});
// your code...
})
I've created a Nuxt plugin that is loaded in the config file with some global functions. In one function, I'd like to access the router, and push to a new route. I am getting an error that router is undefined. Can someone help me understand how I access the router here, if its not attached to the context.
export default (context, inject) => {
const someFunction = () => {
context.router.push({ name: 'route-name' } })
}
}
Try to destruct the context then use app to access the router :
export default ({app}, inject) => {
const someFunction = () => {
app.router.push({ name: 'route-name' } })
}
}
I figured this out. When using context, you can access the router, like this:
context.app.router
I want to create a plugin for Nuxtjs to log everything I want only in client mode, something like this :
// ~/plugins/client-log.js
export default ({ app }, inject) => {
app.clog = string => console.log(string)
}
This plugin is working in components where I have access to context for example:
export default {
fetch({app}){
app.clog("some string")
}
};
But I want to be able to use it inside vuex (actions, mutations...). How can I do that?
Thanks in advance.
You're so close, you just need to change one thing:
// ~/plugins/client-log.js
export default ({ app }, inject) => {
inject('clog', string => console.log(string))
}
Then you're able to call it like:
export default {
fetch({app}){
// Note: inject will automatically prefix with a "$"
app.$clog("some string")
},
mounted() {
// this.$clog can also be accessed within vuex
this.$clog("I'm in a component")
}
};
I'm currently working on a new Vue.js application. It depends heavily on api calls to my backend database.
For a lot of things I use Vuex stores because it manages shared data between my components. When looking at other Vue projects on github I see a special vuex directory with files that handles all the actions, states and so on. So when a component has to call the API, it includes the actions file from the vuex directory.
But, for messages for example, I don't want to use Vuex because those data is only important for one specific view. I want to use the component specific data here. But here is my problem: I still need to query my api. But I shouldn't include the Vuex actions file. So in that way I should create a new actions file. This way I have a specific file with api actions for vuex and for single components.
How should I structure this? Creating a new directory 'api' that handles actions for both vuex data and component-specific data? Or separate it?
I am using axios as HTTP client for making api calls, I have created a gateways folder in my src folder and I have put files for each backend, creating axios instances, like following
myApi.js
import axios from 'axios'
export default axios.create({
baseURL: 'http://localhost:3000/api/v1',
timeout: 5000,
headers: {
'X-Auth-Token': 'f2b6637ddf355a476918940289c0be016a4fe99e3b69c83d',
'Content-Type': 'application/json'
}
})
Now in your component, You can have a function which will fetch data from the api like following:
methods: {
getProducts () {
myApi.get('products?id=' + prodId).then(response => this.product = response.data)
}
}
Similarly you can use this to get data for your vuex store as well.
Edited
If you are maintaining product related data in a dedicate vuex module,
you can dispatch an action from the method in component, which will internally call the backend API and populate data in the store, code will look something like following:
Code in component:
methods: {
getProducts (prodId) {
this.$store.dispatch('FETCH_PRODUCTS', prodId)
}
}
Code in vuex store:
import myApi from '../../gateways/my-api'
const state = {
products: []
}
const actions = {
FETCH_PRODUCTS: (state, prodId) => {
myApi.get('products?id=' + prodId).then(response => state.commit('SET_PRODUCTS', response))
}
}
// mutations
const mutations = {
SET_PRODUCTS: (state, data) => {
state.products = Object.assign({}, response.data)
}
}
const getters = {
}
export default {
state,
mutations,
actions,
getters
}
Note: vue-resource is retired ! Use something else, such as Axios.
I'm using mostly Vue Resource.I create services directory, and there put all connections to endpoints, for e.g PostService.js
import Vue from 'vue'
export default {
get(id) {
return Vue.http.get(`/api/post/${id}`)
},
create() {
return Vue.http.post('/api/posts')
}
// etc
}
Then in my file I'm importing that service and create method that would call method from service file
SomeView.vue
import PostService from '../services/PostService'
export default {
data() {
item: []
},
created() {
this.fetchItem()
},
methods: {
fetchItem() {
return PostService.get(to.params.id)
.then(result => {
this.item = result.json()
})
}
}
}
Based on concept of Belmin Bedak`s answer, i have wrapped it all into a simple library:
https://github.com/robsontenorio/vue-api-query
You can request your API like this:
All results
// GET /posts?filter[status]=ACTIVE
let post = await Post
.where('status', 'ACTIVE')
.get()
Specific result
// GET /posts/1
let post = await Post.find(1)
Editing
// PUT /posts/1
post.title = 'Awsome!'
post.save()
Relationships
// GET /users/1
let user = await User.find(1)
// GET users/1/posts
let posts = await user
.posts()
.get()
