Unfortunately, no, you can’t add a <script> tag to a specific component via template.

In your case you have some options:

1: Use NPM

Propertly install the dependency using npm

• Pros: proper usage of NPM and Webpack; scoped definition;
• Cons: the script must be available as a NPM package.
• Note: when available this is the recommended approach.

• Steps:

  • For your case, you can check in datatables official page they do have a NPM package. I could be used like:

    npm install --save datatables.net-dt
    

  • And in your .vue file:

    <script>
      require( 'datatables.net-dt' )();
      export default {
        name: 'Index',
        data() {
          return { 
          }
        }
      }
    </script>
    

2: Add <script> tag to index.html

Locate and a dd the <script> tag to your index.html

• Pros: the <script> tag is clearly (and declaratively) added to the HTML source. The script will only be loaded once.
• Cons: the script will be globally loaded.
• Steps:
  • Just add the <script type="text/javascript" src="https://cdn.datatables.net/v/dt/dt-1.10.16/sl-1.2.5/datatables.min.js"></script> to the end of the index.html file, preferably right before </body>.

3: Create the <script> tag programatically

The other alternative is to create the script tag programatically at the component, when the component is lodaded.

• Pros: the code stays in the component only. Your external script will be loaded only when the component is loaded.
• Cons: the script still will be globally available once it is loaded.

• Steps/Code:

  <script>
    export default {
      name: 'Index',
      data() {
        return { 
        }
      },
      mounted() {
        if (document.getElementById('my-datatable')) return; // was already loaded
        var scriptTag = document.createElement("script");
        scriptTag.src = "https://cdn.datatables.net/v/dt/dt-1.10.16/sl-1.2.5/datatables.min.js";
        scriptTag.id = "my-datatable";
        document.getElementsByTagName('head')[0].appendChild(scriptTag);
      }
    }
  </script>
