I'm having an issue with a linting error in a vue.js project. The error that I get looks like this:
/Users/mikecuddy/Desktop/coding/data_science_projects/statues/client/src/store/modules/common.js
4:1 error Dependency cycle via @/store/index:4 import/no-cycle
I have no idea how to get rid of this error. I tried renaming files, using this.$router and this.$store with no luck. Here is some of my code:
router -> index.js: The data path is the main one I want to get to. Notice that I have the store import files commented out - that does get rid of the dependency error but then I have issues with doing something like:
this.$store.state.common.loginFlag
as opposed as importing the store and doing this:
store.state.common.loginFlag
import Vue from 'vue';
import VueRouter from 'vue-router';
// import store from '../store/index.js';
// import store from '@/store/index';
import Home from '../views/Home.vue';
Vue.use(VueRouter);
const routes = [
{
path: '/data',
name: 'Data',
component: () => import('../views/Data.vue'),
beforeEnter: (to, from, next) => {
if (this.$store.state.common.loginFlag === false) {
next('/login');
} else {
next();
}
},
beforeRouteLeave: (to, from, next) => {
if (this.$store.state.common.loginFlag === false) {
next('/login');
} else {
next();
}
},
},
];
const router = new VueRouter({
routes,
});
export default router;
store/modules/common.js:
import Vue from 'vue';
import Vuex from 'vuex';
import axios from 'axios';
import router from '../../router';
Vue.use(Vuex);
const data = {
userNotFound: false,
passwordNoMatch: false,
loginFlag: false,
};
const getters = {
userNotFound: (state) => state.userNotFound,
passwordNoMatch: (state) => state.passwordNoMatch,
loginFlag: (state) => state.loginFlag,
};
const actions = {
login: ({ commit }, { payload }) => {
const path = 'http://localhost:5000/login';
axios.post(path, payload)
.then((res) => {
if (res.data.login_flag) {
commit('session/setUserObject', res.data.user, { root: true });
commit('setLoginFlag', res.data.login_flag);
// Tried this:
router.push{ name: 'Data' }
// As well as trying this:
this.$router.push({ name: 'Data' });
}
commit('setNoPasswordMatch', res.data.Password_no_match);
commit('setUserNotFound', res.data.Not_found);
})
.catch((error) => {
console.log(error);
});
},
};
// I have mutations but did not think they'd be needed
const mutations = {};
export default {
namespaced: true,
state: data,
getters,
actions,
mutations,
};
In the common.js file I've tried commenting out:
import router from '../../router';
and that seemed to work - got the Dependency cycle error to go away and in the router/index.js file I was able to get to the route but had an issue with this.$store.state.common.loginFlag when I commented out import store from '@/store/index'; If I leave in the import of: import store from '@/store/index'; then I get the dependency cycle error.
I've also found some help at these other stack pages:
TypeError: Cannot read properties of undefined (reading '$router') vuejs
dependency cycle detected import/no-cycle
I will say that I hate using linters and that's what's giving me the problem here.
Here is the code for store/index.js:
import Vue from 'vue';
import Vuex from 'vuex';
import common from './modules/common';
import session from './modules/session';
Vue.use(Vuex);
export default new Vuex.Store({
modules: {
common,
session,
},
});
