Can I access properties from the index.html file within the Vue.js mount element?

<!DOCTYPE html>
<html lang="">
  <head>
    <meta charset="utf-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
    <meta name="viewport" content="width=device-width,initial-scale=1.0" />
    <link rel="icon" href="<%= BASE_URL %>favicon.ico" />
    <title><%= htmlWebpackPlugin.options.title %></title>
  </head>
  <body>
    <noscript>
      <strong
        >We apologize, but <%= htmlWebpackPlugin.options.title %> requires JavaScript to function properly. Please enable it to continue.</strong
      >

    <div id="app" thisIsAProp="This is what I need"></div>
    <!-- built files will be auto injected -->
  </body>
</html>

In my main.js file, the application is mounted on #app. To access the properties of the <div id="app"> element in my App.js file, I attempted using web-components which worked for a basic app. However, an additional requirement is that I must be able to override the CSS variables within the parent web page. When creating web components, Vue generates them with a shadow-dom. Is there a more effective method to retrieve values from the vue mount element?

Answer №1

Information can be transferred from the page to an entry point using various methods:

<script>
window.myApp = {
  foo: 'bar'
}
</script>
<div id="app"></div>

This information can then be accessed within the application with window.myApp.foo.

Alternatively, string data (including JSON) can be passed using HTML attributes, commonly utilizing data attributes:

<div id="app" data-foo="bar"></div>

To access this data within the application, one would use

document.querySelector('#app').dataset.foo
.

Answer №2

This solution resolved my issue

Successfully retrieved the attributes from index.html and incorporated them into my App.vue file by:

  beforeMount() {
    this.requiredDetails = this.$parent.$el.getAttribute("thisIsAProp");
  },
