How to set Content Security Policy Headers in a Vue.js app

I'm trying to make my Vue app secure, by eliminating clickjacking.

I'm not sure how to set the headers of the Vue server, the methods the X Frame or Frame Ancestor directives in a meta tag like:

   <meta http-equiv="Content-Security-Policy" content="X-Frame-Options: DENY:"
    />

However, the links below say that this is unsupported https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Frame-Options https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy/frame-ancestors

I realise that for API requests, these headers should be set in the backend, however, this is to load the home page of the app (no api requests made).

How can I set these headers in my Vue.js server

The homepage of the app is still loaded over HTTP.

The browser makes an HTTP request to get an HTML document. That HTML document includes <script> elements which cause the browser to fetch some JS. The browser runs some JS and uses it to modify the HTML document in the Vue app.

You should configure the X-Frame-Options and Content-Security-Policy to be served in the HTTP response headers for the response that delivers that initial HTML document which bootstraps the application.

The not-so-good approach is to set a CSP using a <meta> tag (in that same HTML document). You can't set X-Frame-Options that way.
