When i am learning the vue-test-utils from the offical site conditional-rendering.
I tried to change the option api to composition api.
It seems like the mount option data not working with the composition api.
Nav.vue Composition API test FAIL
<template>
<div>
<a id="profile" href="/profile">My Profile</a>
<a v-if="admin" id="admin" href="/admin">Admin</a>
</div>
</template>
<script setup lang="ts">
import { ref } from 'vue'
const admin = ref(false)
</script>
Nav.vue Option API test PASS
<template>
<div>
<a id="profile" href="/profile">My Profile</a>
<a v-if="admin" id="admin" href="/admin">Admin</a>
</div>
</template>
<script>
export default {
data() {
return {
admin: false,
}
},
}
</script>
Nav.spec.js test
test('renders an admin link', () => {
const wrapper = mount(Nav, {
data() {
return {
admin: true
}
}
})
// Again, by using `get()` we are implicitly asserting that
// the element exists.
expect(wrapper.get('#admin').text()).toEqual('Admin')
})
I found a solution but I don't know if it's a good solution
test("renders an admin link", async () => {
const wrapper = mount(Nav);
wrapper.vm.admin = true;
await nextTick();
expect(wrapper.get("#admin").text()).toEqual("Admin");
});

Hi everyone and sorry for the title, I'm not really sure of how to describe my problem. If you have a better title feel free to edit !
A little bit of context
I'm working on a little personal project to help me learn headless & micro-services. So I have an API made with Node.js & Express that works pretty well. I then have my front project which is a simple one-page vue app that use vuex store.
On my single page I have several components and I want to add on each of them a possibility that when you're logged in as an Administrator you can click on every component to edit them.
I made it works well on static elements :
For example, here the plus button is shown as expected.
However, just bellow this one I have some components, that are loaded once the data are received. And in those components, I also have those buttons, but they're not shown. However, there's no data in this one except the title but that part is working very well, already tested and in production. It's just the "admin buttons" part that is not working as I expect it to be :
Sometimes when I edit some codes and the webpack watcher deal with my changes I have the result that appears :
And that's what I expect once the data are loaded.
There is something that I don't understand here and so I can't deal with the problem. Maybe a watch is missing or something ?
So and the code ?
First of all, we have a mixin for "Auth" that isn't implemented yet so for now it's just this :
Auth.js
export default {
computed: {
IsAdmin() {
return true;
}
},
}
Then we have a first component :
LCSkills.js
<template>
<div class="skills-container">
<h2 v-if="skills">{{ $t('skills') }}</h2>
<LCAdmin v-if="IsAdmin" :addModal="$refs.addModal" />
<LCModal ref="addModal"></LCModal>
<div class="skills" v-if="skills">
<LCSkillCategory
v-for="category in skills"
:key="category"
:category="category"
/>
</div>
</div>
</template>
<script>
import LCSkillCategory from './LCSkillCategory.vue';
import { mapState } from 'vuex';
import LCAdmin from '../LCAdmin.vue';
import LCModal from '../LCModal.vue';
import Auth from '../../mixins/Auth';
export default {
name: 'LCSkills',
components: {
LCSkillCategory,
LCAdmin,
LCModal,
},
computed: mapState({
skills: (state) => state.career.skills,
}),
mixins: [Auth],
};
</script>
<style scoped>
...
</style>
This component load each skills category with the LCSkillCategory component when the data is present in the store.
LCSkillCategory.js
<template>
<div class="skillsCategory">
<h2 v-if="category">{{ name }}</h2>
<LCAdmin
v-if="IsAdmin && category"
:editModal="$refs.editModal"
:deleteModal="$refs.deleteModal"
/>
<LCModal ref="editModal"></LCModal>
<LCModal ref="deleteModal"></LCModal>
<div v-if="category">
<LCSkill
v-for="skill in category.skills"
:key="skill"
:skill="skill"
/>
</div>
<LCAdmin v-if="IsAdmin" :addModal="$refs.addSkillModal" />
<LCModal ref="addSkillModal"></LCModal>
</div>
</template>
<script>
import LCSkill from './LCSkill.vue';
import { mapState } from 'vuex';
import LCAdmin from '../LCAdmin.vue';
import LCModal from '../LCModal.vue';
import Auth from '../../mixins/Auth';
export default {
name: 'LCSkillCategory',
components: { LCSkill, LCAdmin, LCModal },
props: ['category'],
mixins: [Auth],
computed: mapState({
name: function() {
return this.$store.getters['locale/getLocalizedValue']({
src: this.category,
attribute: 'name',
});
},
}),
};
</script>
<style scoped>
...
</style>
And so each category load a LCSkill component for each skill of this category.
<template>
<div class="skill-item">
<img :src="img(skill.icon.hash, 30, 30)" />
<p>{{ name }}</p>
<LCAdmin
v-if="IsAdmin"
:editModal="$refs.editModal"
:deleteModal="$refs.deleteModal"
/>
<LCModal ref="editModal"></LCModal>
<LCModal ref="deleteModal"></LCModal>
</div>
</template>
<script>
import LCImageRendering from '../../mixins/LCImageRendering';
import { mapState } from 'vuex';
import Auth from '../../mixins/Auth';
import LCAdmin from '../LCAdmin.vue';
import LCModal from '../LCModal.vue';
export default {
name: 'LCSkill',
mixins: [LCImageRendering, Auth],
props: ['skill'],
components: { LCAdmin, LCModal },
computed: mapState({
name: function() {
return this.$store.getters['locale/getLocalizedValue']({
src: this.skill,
attribute: 'name',
});
},
}),
};
</script>
<style scoped>
...
</style>
Then, the component with the button that is added everywhere :
LCAdmin.js
<template>
<div class="lc-admin">
<button v-if="addModal" #click="addModal.openModal()">
<i class="fas fa-plus"></i>
</button>
<button v-if="editModal" #click="editModal.openModal()">
<i class="fas fa-edit"></i>
</button>
<button v-if="deleteModal" #click="deleteModal.openModal()">
<i class="fas fa-trash"></i>
</button>
</div>
</template>
<script>
export default {
name: 'LCAdmin',
props: ['addModal', 'editModal', 'deleteModal'],
};
</script>
Again and I'm sorry it's not that I haven't look for a solution by myself, it's just that I don't know what to lookup for... And I'm also sorry for the very long post...
By the way, if you have some advice about how it is done and how I can improve it, feel free, Really. That how I can learn to do better !
EDIT :: ADDED The Store Code
Store Career Module
import { getCareer, getSkills } from '../../services/CareerService';
const state = () => {
// eslint-disable-next-line no-unused-labels
careerPath: [];
// eslint-disable-next-line no-unused-labels
skills: [];
};
const actions = {
async getCareerPath ({commit}) {
getCareer().then(response => {
commit('setCareerPath', response);
}).catch(err => console.log(err));
},
async getSkills ({commit}) {
getSkills().then(response => {
commit('setSkills', response);
}).catch(err => console.log(err));
}
};
const mutations = {
async setCareerPath(state, careerPath) {
state.careerPath = careerPath;
},
async setSkills(state, skills) {
state.skills = skills;
}
}
export default {
namespaced: true,
state,
actions,
mutations
}
Career Service
export async function getCareer() {
const response = await fetch('/api/career');
return await response.json();
}
export async function getSkills() {
const response = await fetch('/api/career/skill');
return await response.json();
}
Then App.vue, created() :
created() {
this.$store.dispatch('config/getConfigurations');
this.$store.dispatch('certs/getCerts');
this.$store.dispatch('career/getSkills');
this.$store.dispatch('projects/getProjects');
},
Clues
It seems that if I remove the v-if on the buttons of the LCAdmin, the button are shown as expected except that they all show even when I don't want them to. (If no modal are associated)
Which give me this result :
Problem is that refs are not reactive
$refs are only populated after the component has been rendered, and they are not reactive. It is only meant as an escape hatch for direct child manipulation - you should avoid accessing $refs from within templates or computed properties.
See simple demo below...
const vm = new Vue({
el: "#app",
components: {
MyComponent: {
props: ['modalRef'],
template: `
<div>
Hi!
<button v-if="modalRef">Click!</button>
</div>`
}
},
data() {
return {
}
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
<my-component :modal-ref="$refs.modal"></my-component>
<div ref="modal">I'm modal placeholder</div>
</div>
The solution is to not pass $ref as prop at all. Pass simple true/false (which button to display). And on click event, $emit the event to the parent and pass the name of the ref as string...
I am new to vue and trying to build my first vue app using nuxtjs. My problem right now has to do with architecture and folder structure.
In my other non-vue apps I always have a "services" directory where I keep all my code that makes http requests.
example under my services folder I will have a auth.ts file that contains code that posts login credentials to my API. This file/class returns a promise which I access from within my store.
I am trying to do this with vue using nuxtjs but I realised I am unable to access the axios module from anywhere aside my .vue file.
This is an example of how my code is now:
<template>
...
</template>
<script lang="ts">
import Vue from 'vue'
import ActionBar from '../../components/ActionBar.vue'
export default Vue.extend({
components: { ActionBar },
data() {
return {
example: ''
},
methods: {},
mounted() {
this.$axios.$get('/examples').then((res) => {
this.examples = res.data;
})
}
})
</script>
<style>
...
</style>
I would like to move the axios calls to their own files in my services folder. How do I do this?
what you can do is create a file inside the ./store folder, let's imagine, ./store/products.js, that will create a products store, inside, simple getters, mutations and actions:
export const state = () => ({
products: [],
fetchingProducts: false,
})
export const getters = {
getAllProducts(state) {
return state.products
},
hasProducts(state) {
return state.products.length > 0
},
isFetchingProducts(state) {
return state.fetchingProducts
},
}
export const mutations = {
setInitialData(state, products) {
state.products = products
},
setLoadingProducts(state, isLoading) {
state.fetchingProducts = isLoading
},
}
export const actions = {
async fetchProducts(context, payload) {
context.commit('setLoadingProducts', true)
const url = `/api/example/${payload.something}`
const res = await this.$axios.get(url)
context.commit('setInitialData', res.data)
context.commit('setLoadingProducts', false)
},
}
then in your .vue file, you can now use the store as:
<template>
<div>
<div v-if="isFetchingProducts"> loading... </div>
<div v-else-if="!hasProducts">no products found</div>
<div v-else>
<ul>
<li v-for="product in allProducts" :key="product.id">
{{ product.name }}
</li>
</ul>
</div>
</div>
</template>
<script>
import { mapGetters } from 'vuex'
export default {
data () {
return {
products: []
}
},
methods: {
...mapGetters({
isFetchingProducts: 'products/isFetchingProducts',
allProducts: 'products/getAllProducts',
hasProducts: 'products/hasProducts',
})
},
mounted() {
this.$store.dispatch('products/fetchProducts', {})
},
}
</script>
<style>
...
</style>
remember that:
to call a store action, you should use $store.dispatch()
to call a mutation, you should use $store.commit()
to call a getter, you should use $store.getter()
you can also use the Vuex helper mapGetters, mapActions and even mapMutations
You might also know that you can leverage the Plugins in Nuxt, that article has demo code as well so you can follow up really quick
I'm trying to render a list of offers from my vuex store. The problem is when i'm loading my list of offers page, they are not rendered.
Here is my code :
offers.js
export const namespaced = true
export const state = {}
export const mutations = {
[types.UPDATE_OFFERS] (state, offers) {
Object.assign(state, offers)
}
}
export const actions = {
async fetchOffers ({ commit }) {
const { data } = await axios.get('/api/offers')
commit(types.UPDATE_OFFERS, data)
}
}
offers.vue (my page component)
<template>
<div>
<div v-if="offers"
v-for="offer in offers"
:key="offer.id">
<div>
<div>
<router-link :to="{ name: 'offer', params: { offer: offer.id } }">
{{ offer.project }}
</router-link>
</div>
<div>
<div v-if="offer.versions[0] && offer.versions[0].status == 'edition'">
Validate the offer
</div>
</div>
</div>
</div>
</div>
</template>
<script>
import { mapState, mapGetters } from 'vuex'
export default {
computed: {
...mapState(['offers'])
},
beforeMount () {
this.$store.dispatch('offers/fetchOffers')
}
}
</script>
When i'm loading the page, I can see that the store as loaded the offers but the page doesnt render them. The weird thing is when I load the page offers then another page (example createAnOffer) and then I come back to offers, it renders the offers proplery.
I tried beforemount, beforeCreate, mounted, created.
I admit I have no clue what's going on.
Any tip ?
Thank you for your answers.

I'm trying to implement a todo list using modules mode in the vuex store in nuxtjs but get the error this.$store.todo is undefined and cant find much about this relating to nuxt
Can anyone assist please I have
store index.js
export const state = () => ({
})
export const mutations = {
}
store todo.js
export const state = () => ({
todos: [],
})
export const mutations = {
mutations ...
}
export const actions = {
actions ...
}
export const getters = {
getters ...
}
index.vue page
<template>
<div>
<h2>Todos:</h2>
<p> Count: {{ doneTodosCount }} </p>
<ul v-if="todos.length > 0">
<li v-for="(todo, i) in todos" :key="i">
...
</li>
</ul>
<p v-else>Done!</p>
<div class="add-todo">
<input type="text" v-model="newTodoText">
<button #click="add">Add todo</button>
</div>
</div>
</template>
<script>
import { mapState, mapMutations, mapActions, mapGetters } from 'vuex'
export default {
name: 'app',
data () {
return {
newTodoText: ""
}
},
created () {
this.$store.todo.dispatch('loadData')
},
computed: {
...mapState(['todos', ]),
...mapGetters([ 'doneTodosCount', 'doneTodos'])
},
methods: {
toggle (todo) {
this.$store.todo.dispatch('toggleTodo', todo)
},
}
}
</script>
From what i read I thought this should work but doesn't
I should add it all works fine if i don't use modules mode and just have a single index.js setup
Many Thanks
You need to call it differently
this.$store.dispatch('todo/toggleTodo', todo)
Also better to call it in fetch method, not created
I have an issue with the nuxt.js project. I used async the component but when it rending, async wasn't working. This is my code.
I have view document in https://nuxtjs.org/api/ but I don't know what is exactly my issue
Test.vue (component)
<template>
<div>
{{ project }}
</div>
</template>
<script>
export default {
data() {
return {
project : 'aaaa'
}
},
asyncData() {
return {
project : 'bbbb'
}
}
}
</script>
This is index.vue (page)
<template>
<test></test>
</template>
<script>
import Test from '~/components/Test.vue'
export default {
components : {
Test
}
}
</script>
My expected result is
bbbb
But when running on http://localhost:3000 this is actual result
aaaa
I try to search google many times but don't have expected solution for me. Someone help me, please.
Thanks for helping.
The components/ folder must contains only "pure" Vue.js components
So you can't use asyncData inside.
Read this FAQ: https://nuxtjs.org/faq/async-data-components#async-data-in-components-
components/Test.vue (component)
<template>
<div>
{{ project }}
</div>
</template>
<script>
export default {
props: ['project'] // to receive data from page/index.vue
}
</script>
pages/index.vue (page)
<template>
<test :project="project"></test>
</template>
<script>
import Test from '~/components/Test.vue'
export default {
components : {
Test
},
asyncData() {
return {
project : 'bbbb'
}
}
}
</script>
You cannot use asyncData in component.
You can choose to use the fetch method instead.
<template>
<div>
<p v-if="$fetchState.pending">Loading....</p>
<p v-else-if="$fetchState.error">Error while fetching mountains</p>
<ul v-else>
<li v-for="(mountain, index) in mountains" :key="index">
{{ mountain.title }}
</li>
</ul>
</div>
</template>
<script>
export default {
data() {
return {
mountains: []
}
},
async fetch() {
this.mountains = await fetch(
'https://api.nuxtjs.dev/mountains'
).then(res => res.json())
}
}
</script>
