Simple Vue & Vuex fetch example using @feathersjs for realtime data.
// vuex/actions.js
import feathers from 'feathers/client'
import socketio from 'feathers-socketio/client'
import io from 'socket.io-client'
const socket = io('http://localhost:3030')
const app = feathers().configure(socketio(socket))
// Get the message service that uses a websocket connection
const messageService = app.service('messages')
export const fetchMessages = function ({dispatch}) {
// Call the messages service on the server via websocket
messageService.find({}).then(result => {
dispatch('FETCH_MESSAGES', result.data)
})
}
export const addMessage = function ({ dispatch }, text) {
messageService.create({ text }).then(result => {
dispatch('ADD_MESSAGE', result)
})
}
