VMG
allows you to create a vuex
module easily.
See All implementations.
See Customer Example.
- Clone
- Crud
- Export
- Import
- Move
- Sort
Most of the web applications contain CRUD actions. Vuex or other state management libraries like redux
implement stores
which handle CRUD actions.
According to some store patterns each module must contain isLoading
, isLoaded
, data
and errors
properties in own state, therefore, a module's state can be implemented like this;
const customerState = {
list: {
isLoading: false,
isLoaded: false,
data: [],
errors: {}
}
};
Sure, there must be other module members type
, actions
and mutations
. Check completed vuex module according to module pattern.
This module contains list
state with isLoading
, isLoaded
, data
and errors
properties. When fetchCustomer
action is called, these states will be changed according to three action types.
INDEX.REQUEST
, it setsisLoading
true, this means list has been being fetchingINDEX.SUCCESS
, it setsisLoading
false,isLoaded
true and data withpayload.data
, this means list has been fetched and there is no problem when it was happeningINDEX.FAILURE
, it setsisLoading
false,isLoaded
false,data
: empty array (b/c it is a list), this means there is an error and it was failed
Finally, the developer can use these different states of the module in different cases. For instance, isLoading
state can be used by a list to show an indicator or error
that can be used to show an error component.
The purpose of VMG
is reducing code lines and making development easy.
- If you have a large application which contains CRUD actions in each page/module/component.
- If you want to control async states.
- If you want to set a rule which limits to do CRUD actions.
Import generator members.
import { createCrudActions, createCrudActionTypes, createCrudMutation, createCrudState } from 'vuex-module-generator';
createCrudState
returns an object which contains list
, active
, creating
, updating
, destroying
properties.
These properties contain some sub-properties. Check CRUD state .
createCrudActions
returns CRUD methods to manage index
, show
, create
etc. resource.
Check CRUD actions .
createCrudActionTypes
returns action types which will be used by createCrudActions
.
createCrudMutation
return functions which handle CRUD
state mutations. Check CRUD mutations .
Note: This example can be used for other VMG
members.
/* eslint-disable no-param-reassign */
import { createCrudActions, createCrudActionTypes, createCrudMutation, createCrudState } from 'vuex-module-generator';
export const types = {
...createCrudActionTypes('MODULE_NAME')
};
export const actions = createCrudActions(types);
export default {
state: { ...createCrudState() },
mutations: { ...createCrudMutation(types) },
actions: {
async fetchSomeResource({ commit }) {
commit(actions.index.request());
try {
const res = await asyncSomeResourceAction();
const { data, meta } = res.data;
commit(actions.index.success({ data }));
return { data, meta };
} catch (error) {
commit(actions.index.failure(error));
return Promise.reject(error);
}
}
}
};

Thanks Altay Aydemir, he was my previous developer which wrote this factory for redux, I have implemented it for vuex. That's all :)
