Is there a way to dynamically register an external component in Vue3 without altering the main project?

In my current project, known as "ProjectMain," I am also working on another project that will act as an extension to ProjectMain - let's call it "MyComponent."

My intention is to create MyComponent as a standalone library. My main question is: can I bring in MyComponent into the ProjectMain application dynamically without making any changes to the existing MainProject code? Essentially, I want to load MyComponent dynamically.

If I were to load the JavaScript within the Document Object Model (DOM), I should be able to utilize it. Here's an illustration of what I have in mind:

<html>  
    <head>
        <script type=“text/javascript” src=“my-component.js”></script>
       //if this loaded then i will load the component in the ProjectMain.

    </head>
    <body>
         <div id="app"></div>
      
   </body>
</html>

Answer №1

To enable dynamic changes in your library when new code is added, you can utilize the npm link command.

In your library directory, run:
Npm link
Then, in your main project, use:

Npm link <Your Library Name>

Answer №2

A Vue component may not seem very fancy, but it's essentially a simple javascript object with a designated name (to be referenced in your template).

If you globally register "MyComponent" under the name "X" (which can be done at any time), you can easily dynamically resolve the component in your template using just "X" (this will be the default behavior if the component is not imported statically).

Alternatively, if you don't want to bind any specific name for "MyComponent" in your "ProjectMain", you can utilize dynamic components: https://vuejs.org/guide/essentials/component-basics.html#dynamic-components

The :is property doesn't necessarily have to be a name (which triggers component resolution); it can also be the component object itself (which can be provided to the app through provide/inject).
