How to embed tweets in a page?

I will assume you only want to use these components in a particular page view. My suggestion would be to use a standard ES6 import statement that destructs the objects you are going to use from the package. Go to your project root and run npm install vue-tweet-embed or yarn ... if using it. Then, in the script tag of your component and above the export default you can use import { Tweet, Moment, Timeline } from 'vue-tweet-embed' (or whatever objects you are using from the package). Now, you have access to Tweet, Moment, and Timeline in your component.

Sorry to be dense, but I have very little Vue experience.

So if I just wanted to put a block on the default dashboard page, I don't see an export default block in something like home.js. What do I do?

Also, I assume I am supposed to "npm run dev" after I do all this?

Are you trying to modify one of the Spark templates provided from the framework? You don't have to use those that are not in the spark directories. I am not a fan of the way Taylor used Vue in Spark but it is a heavily opinionated offering so that is just the way he does it. So, he provides a home.js file in the components directory. In that file, he constructing a component and registering it at the same time (not a fan of that but anywho). So, it is not a view component but a functional one so you two choices: you can build off of that and use Blade for the view or you can ignore it and make a single file Vue component...which I recommend if you are not going to use his vast supply of confusing mixins (again not a fan of those either).

If it were me, I would opt for the single file component. The basic template is:

<template>
  <div>Your html goes here</div>
</template>

<script>
  import {Tweet, Moment, Timeline} from 'vue-tweet-embed';

  export default {
    name: 'YourFancyComponent',
    components: {
    },
    ....
  }
</script>

<style scoped>
  /* Your scoped or non-scoped styles here */
</style>
