So I was wondering. When a Vuejs app grows, thus the App.js file grows.
My question is:
How should and can this file be split up so each section of the site uses its own app.js file?
You can create separate functions or classes then import them to the App.js via import or using Require.js, Common.js etc. And the just call them inside the App.js
If you find yourself wanting separate Vue instances / more than one Single Page App, you can try this webpack template.

I've searched a lot but I didn't find anything useful about this. I need to create a web-component with Stencil JS and I would like to split it in sub-components.
Is that possible doing this without exporting the whole component library, but instead exporting only the main component? Thanks in advance.
In case of using UI frameworks (like Bootstrap-Vue, ElementUI or Vuetify, etc.) in our Vuejs application, it's possible to import entire UI framework components & stylesheets from node_modeules in the App.vue(or in the application entry point), or importing a particular ui component in particular Vue file/Component as needed.
The demonstration of these two approches looks like:
For scenerio 1
in App.vue
import BootstrapVue from 'bootstrap-vue'
For scenerio 2
in any particular .vue file
import {BContainer} from 'bootstrap-vue'
So,In case of the first option, does it make the application slower or less performing as all components from UI framework is loading for each route change? Also, its's loading some components that are not needed.
On the other hand, it's quite inconvenient to import each ui component in every .vue file.
So what is the best practice for small or large scale web applications?
Does the practice is same for other JS frameworks/Libraries link React or Angular?
Thanks in advance.
Scenario 1 – register all components globally
All components from the library will be available to use everywhere.
If you change or update the library and some of the component names have changed, you won't get any errors at build time.
Scenario 2 – pick-and-choose specific components locally
Gets annoying to have to import each component when you want to use it.
Only components that are actually used (imported) will be included in the bundle (if using webpack or something similar). Results in a smaller bundle size.
It is clearer to look at the template and know where each component comes from. If you have lots of globally-defined components then there is no clear link between a component and where it came from.
If you change or update the library and some of the component names have changed, you will get build errors due to missing modules.
So,In case of the first option, does it make the application slower or less performing as all components from UI framework is loading for each route change? Also, its's loading some components that are not needed.
It does make a difference when you are importing the entire package globally. Also it won't reload the package for every route change as you have the import inside App.vue. It will be done once when your app is loaded for the first time.
I found this article very helpful on how to optimize loading 3rd party components into vue app.
On the other hand, it's quite inconvenient to import each ui component in every .vue file.
End of the day it all comes to how much of tradeoff your development team is willing to make between optimizing the app and adding multiple lines of import code into individual components.
I am trying a new way of writing my ui and I am using straight ESM loading with Vue. As such I am trying to load my HTML files like I would with say Webpack. I have a simple example of what I am talking about. I basically want to take...
export default {
template: "<div>Here is the component. I want this template to be an html file without webpack</div>"
// I want this to be from a url say mysite.net/viewport.html
}
I tried the simple things like
import Template from "/viewport.html"
But of course that didn't work
I think there might be something I can do with dynamic components. Has anyone tried this an come up with a good solution?
I would like to know how I can add an old Three Js code to a page component in Vue Js, like just plain javascript grabed on html script tag, without using methods or computed objects from Vue
I'm using node 10.14, Vue-cli 3 and Vue scaffold
If I understand your question correctly, one way you could probably do this is to have the JavaScript extracted out into a helper file like /lib/3JS.js and then make sure to export it.
Then you could import it into your Vue file and use it there.
I want to use VueJS in a JAVA application. I've already made a big Vue component but now I want to divide this big component in little part...
How to declare components and use them in client side only way ?
Thanks for tips!
Now that I know a little bit more about VueJS, I found my question weird...
Well, we don't have any JS loader so we have to load the html files (with the Vue component declared) in the main html file to be able to use it.
html code...
// import html file with component
// import html file with component
// use component
