[Vue.js] How to simplify and reset props from parent to child components?

when trying to reset data passed as props to children components. How should i write this ?

Context: i’m converting a ThreeJS implementation into Vue/Typescript. It includes a controls panel composed with slider inputs controlling parameters of the Three canvas.
I separated this massive monolithic original code into 3 components :
- child1: the controlsPanel, contains sliders and the reset button
- child2: the Vue-GL canvas, emitting mouse events
- parent: the component hosting initial data, and reseting.

parent :

<template>
<div>
<child1 :prop1=”prop1” :prop2=”prop2” :child1Prop=”child1Prop” :reset=”reset” />
<child2 :prop1=”prop1” :prop2=”prop2” :child2Prop=”child2Prop” />
</div>
</template>

<script lang=”ts”>
import { Component, vue.js } from ‘vue-property-decorator’;

import Child1 from ‘./components/Child1.vue’;
import Child2 from ‘./components/Child2.vue’;

const initialState = {
prop1: 1,
prop2: 2,
child1Prop: ‘some text’,
child2Prop: ‘another text’,
}
export type InitialState = typeof initialState;

@Component({
components: {
Child1,
Child2,
},
})
export default class App extends vue.js {
public prop1!: InitialState[‘prop1’];
public prop2!: InitialState[‘prop2’];
public child1Prop!: InitialState[‘child1Prop’];
public child2Prop!: InitialState[‘child2Prop’];

public beforeMount() {
Object.assign(this, initialState);
}

public reset() {
Object.assign(this, initialState);
}
}
</script>

Child code :

<template>

<!– this button is only in Child1 –>
<button type=”button” @click=”resetCamera”>Reset</button>
</template>

<script lang=”ts”>
// import VueAsyncComputed, { IAsyncComputedProperty } from ‘vue-async-computed’;
import { Component, Prop, vue.js } from ‘vue-property-decorator’;
import { InitialState } from ‘../App.vue’;

@Component
export default class ChildX extends vue.js {
@Prop() public prop1!: InitialState[‘prop1’];
@Prop() public prop2!: InitialState[‘prop2’];
@Prop() public childXProp!: InitialState[‘childXProp’]; // Specific prop

// computed getters and methods using this.prop1 etc…

// this method is only in Child1
public resetCamera() {
this.reset();
}
}
</script>

Properties prop1 and prop2 are controlled by Child1 component and consumed by Child2. Child2 can also update these props (via mouse events), which should update sliders in Child1 appropriately.

I managed to make Typescript happy, but at the cost of typings everywhere…

Question1: is there a way to simplify while keeping the 2way-bindings between childs and parent App ? (2way-bindings don’t work with above code)

Question2: How to reset all props ? my child1.resetCamera seems to call parent reset() but props are not reseting …

Solution :

When you use props, you should be careful about the point of this kind of data: its main purpose is simply to pass data from parent to child, that is it.

As you might figure that out later, usually it is not a good idea to change props both in parent and child. Why? Consider the following example:

A parent component called mainComponent passes currentID to all its children: headerComponent and footerComponent. However, if you have designed the props to be changed by both parent and children, if footerComponent changes currentID it also changes in headerComponent which may not be expected. How about a third child component being added to the parent component that uses currentID as well? It will be affected too.

Using the above example, my suggestion is: use props in only one-way binding. In other words, mainComponent passes currentID to all its children. If any of these needs to change that props, emit an event by using $emit(“updateCurrentID”, newCurrentID) and catching this up in the mainComponent and, finally, change currentID and that will reflect on all children. But now, you are sure you are updating this props data in only one place (mainComponent).

To emit that, I can think of two possibilities: by $emit itself (docs) or by creating the own custom events, as you can see here - a tutorial by MDN.

Hope it helps

[Vue.js] Unknow custom element error during passing component as a prop in VueJS

Could you explain why vue.js tells me, that Unknown custom element: <MyComponent> - did you register the component correctly? here:

const CustomComponent = Vue.component(‘CustomComponent’, {
template: ‘<div>test</div>’
})

const RenderComponent = Vue.component(‘RenderComponent’, {
props: {
component: {
type: [Function, String]
}
},
template: ‘<component :is=”component”></component>’
})

new Vue({
el: ‘#app’,
components: {
MyComponent: CustomComponent,
RenderComponent
},
template: ‘<render-component component=”MyComponent”></render-component>’
})

https://jsfiddle.net/2qobuj4y/1/

How to pass components to a prop properly here? Are there some examples?

Solution :

MyComponent doesn’t exist so you don’t want to list it in the app’s components. Change the app code to:

new Vue({
el: ‘#app’,
components: {
CustomComponent, // Not actually being used, the template passes a string
RenderComponent
},
template: ‘<render-component component=”CustomComponent”></render-component>’
})

Here is a fiddle

Explanation

You have properly registered CustomComponent as MyComponent in the main app component, and you could use it directly in its template. But then you are also passing a string with the value “MyComponent” to the RenderComponent component. RenderComponent then tries to instantiate a MyComponent component, but none exists in the global scope where it is looking for it. (It only exists with that name within the main app component where you registered it.)

Alternatively, if you were to use a binding instead when you pass MyComponent (i.e. :component instead of component) it still would not work because you can’t pass components as props.

Interesting Alternative

You mentioned trying to pass it from data instead, and while I can’t say if it’s a good practice, it does work. It could get uglier if you ever migrated to single-file components where you wouldn’t have access to a global scope, and it’s a little confusing, but it does work:

new Vue({
el: ‘#app’,
data: {
MyComponent: CustomComponent // Taken from global scope
},
components: {
// CustomComponent, // No need in this version
RenderComponent
},
template: ‘<render-component :component=”MyComponent”></render-component>’
})

[Vue.js] Define Vue methods functions in different js page

Newbie, sorry in advance for the stupid question

there is a vue.js component vuu

/path_to_main/vue_file/app.js

const vuu = new Vue({
el: ‘#vuu’,
data: {
latitude: ‘longi’,
longitude: ‘lati’
},
created: function(){this.checkIfGeolocationAvailable();},
methods: {
checkIfGeolocationAvailable: function(){
getLocation(); // <– this function
}

}
});

Now to define getLocation() on a different js page say

/path_to_main/vue_file/helper.js

function getLocation() {alert(“Hello”);}

How can I do this? or is this a totally wrong approach?

Solution :

Being modular is never the wrong approach.

Use es6 modules and a transpiler such as webpack, typescript, etc.

helper.js

export function getLocation() {alert(“Hello”);}

main.js

import {getLocation} from ‘./helper.js’

Once you start using a transpiler, you should also consider using vue.js single file components. Furthermore, by leveraging vue-cli-3, you can eliminate much of the heavy boilerplate for the transpiler configuration, testing, and building.

Solution 2:

I created a helper folder, but it was not necessary

helper/getLocation.js

export default function getLocation() {
alert(“Hello”)
}

App.vue

<template>
<div id=”app”>
</div>
</template>

<script>
import getLocation from ‘./helper/getLocation.js’

export default {
name: ‘App’,
data() {
return {}
},
mounted() {
getLocation()
}
}
</script>

[Vue.js] classList is undefined for element that has defined classes

when trying to add and remove classes to an element in Vuejs. The missing link in my code is that the classList returns undefined. Why is this? Thanks. when grabbing the element with the jQuery getElementById shorthand $

<template>
<div class=”form-field” id=”outerdiv”>
<div class=”form-field__control”>
<label for=”exampleField” class=”form-field__label”>{fieldLabel}</label>
<input id=”exampleField” v-model=”fieldContent” @blur=”setActive(false, $event)” @focus=”setActive(true, $event)”
type=”text” class=”form-field__input” />
</div>
</div>
</template>

<script>
import $ from “jquery”;

export default {
name: “FormField”,
props: {fieldContent: String, fieldLabel: String},
methods: {
setActive(active, event) {
console.log(“this.fieldContent: “+this.fieldContent);
const formField = event.target.parentNode.parentNode
if (active) {
formField.classList.add(‘form-field–is-active’)
} else {
formField.classList.remove(‘form-field–is-active’)
event.target.value === ‘’ ?
formField.classList.remove(‘form-field–is-filled’) :
formField.classList.add(‘form-field–is-filled’)
}
}
},
updated() {
console.log(“in initialize form field”);
console.log(“this.fieldContent: “+this.fieldContent);
console.log(“result from shorthand getElementById: “+$(“#outerdiv”));
console.log(“classList of element: “+ $(“#outerdiv”).classList);
this.fieldContent === ‘’ ?
$(“#outerdiv”).classList.remove(‘form-field–is-filled’):
$(“#outerdiv”).classList.add(‘form-field–is-filled’)
}
}
</script>

<style>
.form-control{
border-style: none;
width: 100%;
height: 34px;
padding: 0px 0px;
font-size: 20px;
}
</style>

Solution :

While the main issue has been resolved you can simplify the code and at the same time eliminate the need for jQuery by doing it the vue.js way.

By using class bindings you can replace the ifs with a computed prop and if you need direct access to an element you can use refs.

Just run the following snippet to see these concepts in action:

new Vue({
el: ‘#app’,
data: {
fieldContent: ‘’,
fieldLabel: ‘’,
active: false,
},
computed: {
classList() {
return {
‘form-field–is-filled’: this.fieldContent !== ‘’,
‘form-field–is-active’: this.active,
};
}
},
methods: {
setActive(active, event) {
console.log(“this.fieldContent: “+this.fieldContent);

this.active = active;
}
},
updated() {
console.log(“in initialize form field”);
console.log(“this.fieldContent: “+this.fieldContent);
console.log(“result from shorthand getElementById: “, this.$refs.outerDiv);
console.log(“classList of element: “+ this.$refs.outerDiv.classList);
}
});
.form-control{
border-style: none;
width: 100%;
height: 34px;
padding: 0px 0px;
font-size: 20px;
}

.form-field–is-active {
border: 1px solid green;
}

.form-field–is-filled {
outline: 1px dotted blue;
}
<script src=”https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>

<div id=”app”>
<div class=”form-field” id=”outerdiv” :class=”classList” ref=”outerDiv”>
<div class=”form-field__control”>
<label for=”exampleField” class=”form-field__label”>{fieldLabel}</label>
<input id=”exampleField” v-model=”fieldContent” @blur=”setActive(false, $event)” @focus=”setActive(true, $event)”

[Vue.js] Update state after using dispatch

Im using vuex and there is an action

storeExpense(context, params){
axios.post(‘api/expenses’, params)
.then( response => {
console.log(“Expense Created”);
})
.catch( error => {
console.log(error);
});
}

and on my Expense.vue.js im using the action via

this.$store.dispatch(‘storeExpense’,this.expense)
.then( response => {
this.modalShow = false
this.$swal(
‘Success’,
‘Expense has been created!’,
‘success’
)
})

I dont have an error but after the expense was created the state is not updating therefore I need to refresh the page in order for my table to get the latest data.

there is a mutation called

mutateExpenses(state, payload){
state.expenses = payload
}

however when i use this after the response it overrides the whole state.expenses object to a single object because this.expense is a single object

Im new to vuex.

Solution :

You must update the store using mutations that are called inside the actions.
I suggest you to dive a bit into the Vuex documentation, especially the mutations and actions :)

Here is an example of how to use the store :

It goes dispatch –> action –> mutation

// the store
const store = new Vuex.Store({
state: {
posts: [],
isLoading: false
},

mutations: {
// Must be called by actions AND ONLY by actions
add(state, post) {
// Add the given post to the ‘posts’ array in our state
Vue.set(state.posts, state.posts.length, post)
},
busy(state) {
Vue.set(state, ‘isLoading’, true)
},
free(state) {
Vue.set(state, ‘isLoading’, false)
}
},
actions: {
create({
commit
}, post) {
commit(‘busy’)
axios.post(‘https://jsonplaceholder.typicode.com/posts', post)
.then(response => {
// Call the mutation method ‘add’ to add the newly created post
commit(‘add’, response.data)
})
.catch((reason) => {
// Handle errors
})
.finally(() => {
commit(‘free’)
});
},
}
})

// the vue.js app
new Vue({
el: “#app”,
store,
data: {
post: {
title: ‘foo’,
body: ‘bar’,
userId: 1
}
},
methods: {
onButtonClicked() {
this.$store.dispatch(‘create’, this.post)
}
}
})
<script src=”https://cdnjs.cloudflare.com/ajax/libs/axios/0.18.0/axios.min.js"></script>
<script src=”https://cdnjs.cloudflare.com/ajax/libs/vuex/3.1.0/vuex.min.js"></script>
<script src=”https://cdnjs.cloudflare.com/ajax/libs/vue/2.6.10/vue.min.js"></script>
<div id=”app”>
<button @click=”onButtonClicked”>Create Post</button>
<div>Posts : <span v-if=”$store.state.isLoading”>Requesting</span></div>
<div v-for=”post in $store.state.posts”>
{post}
</div>
</div>

[Vue.js] Filter json objects in javascript

My object is as below

“permission”: {

How would I filter to find if 255 is true

Solution :

const test = {
“permission”: {
“delete”: {
“253”: false,
“255”: true
}
}
}

const hasDelete255 = test.permission.delete[“255”];

[Vue.js] How do You Correctly Import Three.js Modules in a Vue Project?

to use three.js to display a gltf file. In order to do that there is to import the GLTFLoader module from the three.js node package.

According to the documentation the way to achieve this is by importing it like this:

import { GLTFLoader } from ‘three/examples/jsm/loaders/GLTFLoader.js’;

And this line does not give me any errors. If I change the path in any way the console tells me that they can’t find the module, so I know for sure that it is finding a module the way it’s written right now.

However, when I go on to invoke the loader like the documentation says using this line:

var loader = new THREE.GLTFLoader();

I get this error:

GLTFLoader is not a constructor

What am I doing wrong?

I tried multiple ways of importing the loader without any success and every thread I can find seems to use the same way of importing it without getting the same errors. Here’s the relevant code in context.

<template>
<div id=”container”></div>
</template>

<script>
import * as THREE from ‘three’
import { GLTFLoader } from ‘three/examples/jsm/loaders/GLTFLoader.js’;

export default {
name: ‘ThreeTest’,
data() {
return {
camera: null,
scene: null,
renderer: null,
mesh: null
}
},
methods: {
init: function() {
var loader = new THREE.GLTFLoader();

loader.load( ‘assets/Models/eames_lounge_chair/scene.gltf’, function ( gltf ) {

scene.add( gltf.scene );

}, undefined, function ( error ) {

console.error( error );

} );

},
animate: function() {

},
onWindowResize: function() {
camera.aspect = window.innerWidth / window.innerHeight;
camera.updateProjectionMatrix();

renderer.setSize( window.innerWidth, window.innerHeight );
}
},
mounted() {

this.init();
this.animate();
}
}
</script>

<style scoped>

#container {
width: 10em;
height: 10em;
}
</style>

Solution :

When you import the loader via

import { GLTFLoader } from ‘three/examples/jsm/loaders/GLTFLoader.js’;

then it’s not necessary to use the THREE namespace when creating the loader. Just do this:

var loader = new GLTFLoader();

[Vue.js] Transition-group unexpected behavior when using a filtered array

I’ve got an issue with transition-group.
The problem is that I’m trying to render list filtered by some condition. In my example - depending on min/max bounds.

How can it be fixed?

Initially, I’ve tried to use computed value for Array rendered inside the transition-group. But obviously, it returned new array every time range slider value got updated. So I’ve tried to use @input event handler which updates list that should be rendered only when it needs to be updated.
What confuses me most is that I’ve tried to set up transition-group hooks for @enter @enter-to @leave @leave-to events and they are fired correctly. Just once. I’ve also tried to make it JS-driven but transition-group sets CSS classes even if I set :css=”false” :duration=”500”.

I’ve made a simplistic example that illustrates the problem. codesandbox.io

What I expect is that list (Array) gets updated, then it triggers transition-group contents to re-render. And FLIP animations are performed.
But the problem is that if the value that is used as filter condition is changed rapidly ( e.g. User drags range slider using mouse ) animations are either not performed at all, or causes lags. Watch accurately on behavior when you drag the range slider from left to right (animations are laggy) and it differs from what you see when you drag it from right to left (no animations are performed for the first element).
Please also notice that if you click on the slider to set value - animations are performed just as expected.

Solution :

Ref: “And FLIP animations are performed”…

Considering you want to flip the item, I wouldn’t use a <transition-group> at all.
I’d use a 3d rotation effect (which when guessing is what you want) and control the rotation angle using a computed property, based on the relation between item props and range value.

The example could be extended to handle a larger number of items and map them onto the sides of the shape (5 replacing 1 when you roll past 4, and so on…), but, since you only have 3 values, it seemed out of scope.

Here it is:

Vue.config.devtools = false;
