What is the difference between importing Vue.js library and installing it via Vue-CLI? - vue.js

Could you please explain what is the main difference between different Vue installation methods for building a one-page website (page routing) with Vue and an Electron app using Vue:
importing Vue.js library via <script>
installing it via Vue-CLI
This installation guide doesn't really help understand the difference.
Is my site / app going to work slower if I just import Vue via <script>?

The <script> include is for including the Vue library in your webpage just like you would any other JavaScript library. Vue will be available on the window object for you to access globally. All external JavaScript must be included like this one way or another, even if you use vue-cli.
vue-cli is just a tool which generates Vue projects from templates. The setup really depends on the template that you use; I imagine most people would probably use the webpack template for medium to large sized Vue projects. This will initialize a node project directory containing all files necessary to develop, debug, test and build a Vue project. Webpack takes care of bundling all modules into a single JavaScript bundle which is included into the webpage via <script>. You can also benefit from vue-loader which allows you to write Vue components in *.vue files.
Is my site / app going to work slower if I just import Vue via <script>?
I mean, not really, no (your development speed might be hindered though since you won't benefit from all the bells and whistles that vue-cli sets you up with). Your question applies more to the development approach that you will follow for developing a Vue web application.

Testing common code in multiple files in Vue with Jest

We have a website using Vue 2.0 and Jest as testing environment. In most vue components we have the same type of watchers which means we just have to copy the same code between all of them to make sure the code is covered.
Is there a way to run this for all files automatically?
Haven't been able to find a valid solution to this.

Title cannot contain "Automatic import from npm to vue app"

npm is great to download some js libraries, but including the into a vue app is really hard. i have no idea if there is an "official" way, but searching online i see so many different approaches.
sometimes it is imported in the app.js file, sometimes in the .vue files inside the tags. i have also seen that there are vue plugins that handle differently. how should i know if i have a vue plugin or not? i don't even know what the other option would be. like a vue module instead of a vue plugin?
is there a way that the vue app just includes/imports the stuff from node_modules so i can use it? so that after doing some npm install it is all available?
Npm just downloads the library into the node_modules folder and let's you access it where you need it.
If it's a vue component you need to import it in a vue file, because that's where you need it.
If it's a vue plugin you have to import it in the main js file because that's where it gets initalized in the whole app.
Looks like you are new to vue, I suggest you to take a look at this simple guide where you can learn some basic stuff.

How to adapt Vue component for browser build?

I have a legacy web application which I have introduced Vue into in a few places, via CDN. I have upgraded it from Vue 2 to Vue 3. There is a component used there which breaks with Vue 3, but there is a Vue 3 version of it. However, the author states this: "The component is packaged mainly for use with bundlers, if you require a browser build - post an issue." I do require a browser build. Is there some easy way I can do this for myself? I wasn't planning to use a bundler for this application, so I'm hoping I can use the existing modules to create a .js file I can use from the browser?

material-components-web for vue js

I have a website based on Vue framework and webpack.
I came across this css framework developed by Google (Material Components Web) where you can directly get started using a cdn or an npm package. It worked extremely well for a simple html/javascript based website. But, I am having issues setting it up for the Vue project.
There are other wrappers available for Vue framework like Veutify and Vue Material. But, it comes with lot of additional stuff like the grid layout which I don't want the developers to follow as we are already using a flex layout. I only want the component library.
So, is there a way use the Material Components Web with the Vue framework?
I didn't get the Material Components Web working with the Vue framework. But I did found another light-weight material design framework i.e. Material Design Lite.
Note: It is not specific to any framework. It lets you add Material Design look to your website developed in any framework
You can easily get started with a wide variety of options like cdn, bower, npm or even by downloading the files.
Material Components Web has modular architecture. Each component or API is distributed as a separate package. It means that you can use them separately, although there are some dependencies.
Also there is "root" package - material-components-web, which just references all other packages.
By default, when you add a package, it will not be included in your app. You'll need to import component's SCSS and optionally JavaScript. Basically like you would use any other component.
Reference this Vue app template as an example. As you can see here, it references only subset of MDC's components/APIs.

Include VueJS Plugin without Javascript Package Manager

How can I use VueJS plugins if I don't use any Javascript Package Managers (NodeJS, NPM)?
I'm building an app made from a Bootstrap template and Server Side framework in Coldfusion (CFWheels).
I wanted to use some of VueJS's functionality such as two-way data-binding, easier integration of animation using animate.css, etc. I included it via
<script src="https://unpkg.com/vue"></script>
However, I can't use NPM as the app will be continually be improved and maintained in production.
I wanted to use some VueJS plugin such as VueJS typeahead.
When I include the script, and try the documentation, there are errors in the Javascript like being unable to import, export module, require. I think these are modern Javascript coding style that are not recognized in my setup because I didn't use the NPM and require those polyfills.
Is there a way that I can make those VueJS plugins work? Or if I can just include the polyfills needed and proceed with the plugin documentations so the browser will understand those new JS terms without using NPM or other Javascript Package Manager.
