How to load a vuejs build into another vuejs?

To load a Vue.js build into another Vue.js application, you need to properly configure the new application to include the built Vue.js library as a dependency. Here's a step-by-step guide on how to do it:

Install the new Vue.js application: If you haven't created the new Vue.js application yet, you can use Vue CLI to create a new project. Run the following command in your terminal:
```
vue create my-new-project
```
Follow the prompts to configure the project.
Install the built Vue.js library as a dependency: You can download the built Vue.js library from the official website (https://vuejs.org/v2/guide/installation.html#Runtime-only) or use a CDN link. In this example, we'll use the CDN link.

Open the package.json file of your new project and add the following line under the "dependencies" object:
```
"vue": "^2.x.x"
```
Replace ^2.x.x with the version number of the built Vue.js library you downloaded.

Then, add the following line under the "scripts" object:
```
"install-vue": "cd node_modules/vue && npm install"
```
Save the file and run the following command to install the new dependency:
```
npm run install-vue
```

Configure the new application to use the built Vue.js library: Open the main.js file of your new project and replace the content with the following code:

import Vue from 'vue'
import App from './App.vue'

Vue.config.productionTip = false

new Vue({
  render: h => h(App),
  el: '#app'
})

// Add this line to import the built Vue.js library
import 'vue'

Save the file.

Load the built Vue.js library: Open the index.html file of your new project and add the following line just before the closing </body> tag:
```
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.min.js"></script>
```
Replace the CDN link with the path to the built Vue.js library if you downloaded it locally.
Build the new application: Run the following command to build the new application:
```
npm run build
```

Now, you have successfully loaded a Vue.js build into another Vue.js application. The new application will use the built Vue.js library instead of the one included in the Vue CLI.
