vuex-socket-sync

Vuex plugin, which makes simple, but very powerful job:

• on each action dispatch it emits socket event, specified for that action, with same payload
• on each received socket event it dispatches one or more actions, specified for such event, with same payload

Installation

npm i vuex-socket-sync

Usage

It works only with vuex modules.

Into each module describing object u can add optional property socket, which should consists from two sub properties: events and actions.

events should be object representing event-to-action mapping and actions should represent action-to-event mapping

Simplest example of socket mapping:

{
  events: {
    answer: 'setAnswer'
  },
  actions: {
    ask: 'question'
  }
}

No problem if you want few modules actions to be dispatched by one event:

events: {
  answer: [
    'setAnswer',
    'logger/logAnswer'
  ] 
}

In case we haven't slash '/' in event or action mapping value it shall be namespaced or prefixed with current module name.

Be patient: that is actual only for right part of mapping. left part always belongs to current module and same named namespace. So you can write:

  event: 'otherModule/action'

but you cannot

  'otherModule/event': 'myAction'

In case we have '=' as mapping value it means, that we shall use same name for event or action

Full Store Example

import socket from 'vuex-socket-sync';
import io from 'socket.io-client/dist/socket.io.slim';

const modules = {
  folders: {
    namespaced: true,
    state: {
      choosenFolder: null,
      path: '',
      tree: [],
      paths: []
    },
    actions,
    mutations,
    socket: {
      events: {
        paths: [
          'fillQueryPaths',
          'settings/saveActualPaths'
        ]
      },
      actions: {
        openUserFolder: 'browse',
        execute: 'interpreter/execute',
        search: '='
      }
    }
  }
};
const state = {};

export default new Vuex.Store({
  strict: 'true',
  state,
  modules,
  plugins: [
    socket(io, modules)
  ]
});

So, what we have here?

On socket event from namespace /folders with name paths shall be dispatched two actions: folders/fillQueryPaths and settings/saveActualPaths.

On dispatch action folders/openUserFolder shall be emitted event browse of namespace /folders.

On dispatch action folders/execute shall be emitted event execute of namespace /interpreter.

On dispatch action folders/search shall be emitted event search of namespace /folders.

As you see you just give socket.io client builder to plugin. It takes care about everything else by it's own
