How can I import node module into svelte component - npm

I'm new to svelte and I am trying to use an installed node module in my dependancies called momentum-slider. In the script tags of my svelte component I have:
import MomentumSlider from "../../node_modules/momentum-slider";
let slider = new MomentumSlider({
el: ".ms-container",
});
In my component's html markup I have the suggested markup as shown in the tutorial at https://scotch.io/tutorials/building-a-fancy-countdown-timer-with-momentumsliderjs
However, I am getting a typeError in the browser console:
I am new to development in general and I am not sure if this is a problem with momentum-slider or an error on my part. Any insights would be much appreciated.

Not sure how to use this library but you should take care of 2 things. First import your package like the following:
import MomentumSlider from "momentum-slider";
Second you need to initialise the MomentumSlider class when the component is mounted using onMount:
import { onMount } from "svelte";
import MomentumSlider from "momentum-slider";
let slider;
onMount(() => {
slider = new MomentumSlider({
el: ".ms-container"
});
});

If you have installed the package properly: npm install momentum-slider
the package is listed in your package.json.
When this fits, you just have to import:
import MomentumSlider from "momentum-slider";

How to use Recaptcha v3 with VueJS using uve-recaptcha-v3 when I get a vue_1.ref is not a function error?

I am using vue-recaptcha-v3 in a VueJS app but am immediately getting an error. My main.js looks like this:
import Vue from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'
import Buefy from 'buefy'
import 'buefy/dist/buefy.css'
import { VueReCaptcha } from 'vue-recaptcha-v3'
Vue.use(VueReCaptcha, { siteKey: 'MYSITEKEY' })
Vue.use(Buefy)
Vue.config.productionTip = false
new Vue({
router,
store,
render: h => h(App)
}).$mount('#app')
Unfortunately when I hit save I get the error below (screenshot included):
Uncaught TypeError: vue_1.ref is not a function
which relates to the following piece of the vue-recaptcha-v3 package:
exports.VueReCaptcha = {
install: function (app, options) {
var isLoaded = vue_1.ref(false);
var instance = vue_1.ref(undefined);
Not sure where to go from here...
I have had the same issue, it seems the most recent package version has this obvious runtime error. However version 1.9.0 works great. So just remove the current package if you use yarn run the following (otherwise the npm equivalent):
yarn add vue-recaptcha-v3#1.9.0
vue-recaptcha-v3 master branch is now using Vue 3.
You're probably using Vue 2, so you should follow the instructions here.
If the type of the package does not influence much what you need. here's one that i use and that works for me.
Link: https://www.npmjs.com/package/vue-recaptcha
After installing you just need to import it into your form.
import VueRecaptcha from 'vue-recaptcha';
Using:
<vue-recaptcha
#expired="captchar = false"
class="mr-8"
#render="cargarCaptchar = true"
#error="captchar = false"
#verify="captchar = true"
sitekey="your code"/>
If that doesn't work, add the following tag to the page header:
<script src = "https://www.google.com/recaptcha/api.js?onload=vueRecaptchaApiLoaded&render=explicit" defer> </script>
If you find that this is not feasible for your project. No problem, as I still think you can help other fellow beginners.

Problem when importing js-cookies in Main.js

I'm trying import js-cookies in my main.js
Main.js
import * as Cookies from "js-cookie";
Vue.use(Cookies)
Using in component
this.$Cookies.set('name', data.user, { secure: true });
Error
TypeError: Cannot read property 'set' of undefined
what is the problem?
I have tried a thousand ways and it still does not work.
Vue.use(name) is used to install a vue plugin. The package will need an install method that receives a vue instance.
#1
You can use the cookies packages without a plugin importing the module in the component
<script>
import Cookies from 'js-cookie';
export default {
methods: {
addCookie() {
console.log('adding the cookie');
Cookies.set('chocolate', 'chookies');
console.log(Cookies.get());
}
}
}
</script>
#2 you can add a VUE plugin and set a Cookies prototype function to the Cookies module.
(Prototype vue functions will be available for components, it's standard to prefix them with $).
src/CookiesPlugin.js
import Cookies from 'js-cookie';
const CookiesPlugin = {
install(Vue, options) {
Vue.prototype.$Cookies = Cookies;
}
};
export default CookiesPlugin;
src/main.js
import CookiesPlugin from './CookiesPlugin';
Vue.use(CookiesPlugin);
In the component
this.$Cookies.set('chocolate', 'chookies');
console.log(this.$Cookies.get());
You are using a NOT Vue (Vanilla JS library) library and you are trying to use it as a Vue resource.
Try using this one instead

Vue.js load component theme without Vue.use

I am using Cool-Select and it requires the following code to load its theme:
import VueSelect from 'vue-cool-select'
Vue.use(VueSelect, {
theme:'material-design'
})
The problem is that I do not want to have to import the entire vue code in order to just use a theme. Also, the components works fini without the theme import; just missing css.
Is it possible to import the theme locally instead in the components part like this?
import { CoolSelect } from 'vue-cool-select'
components:{
CoolSelect,
// import theme here
},
VueSelect is a plugin, i.e. it has install method that will be called when provided to Vue.use. This doesn't affect the application except that it loads styles that are specific to this component.
Since styles weren't exported from the package and are loaded only on plugin installation, this is the only way how CoolSelect component can have its styles loaded without forking the package:
Vue.use(VueSelect, {
theme:'material-design'
})

How to import anime.js to my Vue project?

I have a question regarding importing an anime.js into my vue project. I am using vue cli. How do I include animejs to my project? I tried it this way:
import anime from 'animejs'
Vue.use(anime);
but I get an error in the console that says:
Uncaught TypeError: a.hasOwnProperty is not a function. . .
can you guys help me?
Vue.use() is used only for plugins designed for Vue.js. You can't simply add a library there, it won't work.
My suggestion is that you create that plugin and use it on your project to make anime.js acessible everywhere.
You could do it like this:
//vue-anime.js
import anime from 'animejs';
const VueAnime = {
install (Vue, options) {
Vue.prototype.$animeJS = anime;
}
}
export default VueAnime
Then later
import VueAnime from './vue-anime';
Vue.use(VueAnime);
Now every Vue component will be able to use anime acessing this.$animeJS.
Or simply -
import Vue from "vue";
import anime from 'animejs/lib/anime.min.js';
Vue.prototype.$anime = anime;
Then this.$anime in all components
#Phiter's answer looked good at first, but I wasn't able to get it to work in my vue-cli 3 environment. The below code worked though, so I think it may work for you. This is just a simple way to install an external library into your Vue app and expose it through a prototype:
// animejs.js
import anime from 'animejs'
const install = (Vue, options) => {
Vue.prototype.$animejs = anime
}
export default install
// Then, in your main.js (at least for me)
import VueAnime from './animejs'
Vue.use(VueAnime)
Now, when you need to access the library, just use this.$animejs in your project.
or simply like this in main.js after npm install:
import anime from 'animejs';
Object.defineProperty(Vue.prototype, '$anime', { value: anime });
then use this.$anime tu use it.
To use AnimeJS globally in Vue 3 project, just create a plugin (plugins/anime.js):
import anime from 'animejs';
export default {
install(app, options) {
app.config.globalProperties.$anime = anime;
},
};
Then include it (main.js or elsewhere):
import VueAnime from './plugins/anime';
createApp(App)
.use(VueAnime)
.mount('#app');
And now, it's accessible everywhere by this.$anime.
Please notice that a minor change from the previous version is installing the plugin for Vue 3.

Unknown html tag warning of Bootstrap-Vue.js support in WebStorm

I'm using WebStorm 2017.2.4 and webpack Vue.js project. I have added bootstrap-vue.js to my project and would like to see hints for it and components support.
But instead of that I have got "Unknown html tag" warning.
BTW: bootstrap-vue works as expected when running project.
Do you have any suggestions how to make it work?
UPDATED on 2019/07/30
PHPShtorm(WebStorm) was updated to 2019.2 and now they added better support for vuejs libraries:
https://blog.jetbrains.com/webstorm/2019/07/webstorm-2019-2/#development_with_vue
I've just tested and it works.
OLD answer
I solved this issue by adding components manually.
According to: https://bootstrap-vue.js.org/docs/#individual-components-and-directives
I created new file, e.g. bootstrap.js then register globally components which required
import 'bootstrap/dist/css/bootstrap.css';
import 'bootstrap-vue/dist/bootstrap-vue.css';
import Vue from 'vue';
import navbar from 'bootstrap-vue/es/components/navbar/navbar';
import container from 'bootstrap-vue/es/components/layout/container';
// ...
Vue.component('b-navbar', navbar);
Vue.component('b-container', container);
// ...
It work for me in phpstorm 2018.1
Bootstrap vue uses very dynamic way of defining components. I am using PyCharm with vuejs extension which is unable to resolve the components when registered using
import { Layout } from 'bootstrap-vue/es/components'
Vue.use(Layout)
What I use to do is make a new file bootstrap.js in components directory, and register all bootstrap components I would use like
import Vue from 'vue'
import bContainer from 'bootstrap-vue/es/components/layout/container'
import bRow from 'bootstrap-vue/es/components/layout/row'
import bCol from 'bootstrap-vue/es/components/layout/col'
Vue.component('b-container', bContainer);
Vue.component('b-col', bCol);
Vue.component('b-row', bRow);
and then import this file in main.js
import './components/bootstrap'
Just a little cleaner solution.
#Updated: There're two ways to fix "Unknown html tag" warning: (Global and Local Registration)
Global Registration :
You should have to register your component globally Vue.component(tagName, options) before creating the new Vue instance. For example:
Vue.component('my-component', {
// options
})
Once registered, a component can be used in an instance’s template as a custom element, <my-component></my-component>. Make sure the component is registered before you instantiate the root Vue instance. Here’s the full example:
HTML:
<div id="example">
<my-component></my-component>
</div>
JS:
// global register
Vue.component('my-component', {
template: '<div>A custom component!</div>'
})
// create a root instance
new Vue({
el: '#example'
})
Which will render HTML::
<div id="example">
<div>A custom component!</div>
</div>
Local Registration :
You don’t have to register every component globally. You can make a component available only in the scope of another instance/component by registering it with the components instance option:
var Child = {
template: '<div>A custom component!</div>'
}
new Vue({
// ...
components: {
// <my-component> will only be available in parent's template
'my-component': Child
}
})
The same encapsulation applies for other registerable Vue features, such as directives.

#Before Updated:
In WebStorm, a library is a file or a set of files whose functions and methods are added to WebStorm's internal knowledge in addition to the functions and methods that WebStorm retrieves from the project code that you edit. In the scope of a project, its libraries by default are write-protected.
WebStorm uses libraries only to enhance coding assistance (that is, code completion, syntax highlighting, navigation, and documentation lookup). Please note that a library is not a way to manage your project dependencies.
Source: https://www.jetbrains.com/help/webstorm/configuring-javascript-libraries.html
Simply, upgrade WebStorm from version 2017.2.4 to 2017.3 which fixed this issue. It is tested.
