script to get source code of website (js)

Question

My school blocked CTRL + U, but you can use 'view-source:' before a link to view the code. It takes awhile, so i've been trying to make a script to automatically direct to the source code. However, I keep getting errors because it is not a link

I have tried the following:

var code = fetch(`view-source:https://${location.hostname}${location.pathname}`);
location.href = (code);

and

var code = (`view-source:https://${location.hostname}${location.pathname}`);
location.href = (code);

In the first one, I see a bad request, and in the second, I a blank page with the words "view-source:" followed by the link

fetch() doesn't return a URL you can assign to location.href. It returns a promise, which you can use to get the contents of the web page. — Barmar

view-source: isn't a real protocol you can fetch().

However, just

var resp = await fetch('http://...');
var text = await resp.text();
document.body.textContent = text;

should replace the current document's body with the text contents of that URL...

If you try from frontend to fetch the source code you will run to CORS Problems. But you can use some proxyies like in the example beloow:

fetch('https://api.codetabs.com/v1/proxy?quest=https://stackoverflow.com/questions/75440023/script-to-get-source-code-of-website-js#75440023').then((response) => response.text()).then((text) => console.log(text));
