Feat/url validation

[prakshithamalla-art]

Overview

Closes #270. Updated the isValidHttpUrl function in lib/url.ts to be more permissive with subdomains.

Changes Implemented

• Removed the restrictive manual Regex check for schemes.
• Refactored the function to use the native URL constructor with a fallback protocol. This allows the application to correctly validate and accept deep subdomains (e.g., a.b.c.example.com) while still maintaining security by enforcing http or https protocols.

Why this improves LinkID

• Users can now save links to complex subdomains or project pages that were previously being rejected by the validation logic.

Hey @prakshithamalla-art.I reviewed the changes and have a few things to flag.

URL validation (lib/url.ts)

The simplification looks good and fixes the deep subdomain issue. However, the original code had an extra safety check that rejected non-HTTP schemes (like ftp://, javascript:, data://) early, before even trying to parse the URL:

if (hasScheme && !/^https?:/i.test(value)) {
return false;
}

Your new version removes this and only checks url.protocol after parsing. While that works in most cases, the early rejection was an extra layer of protection. Could you add it back while keeping your simplification? Something like:

export function isValidHttpUrl(value: string) {
try {
const hasScheme = value.includes("://");
if (hasScheme && !/^https?:///i.test(value)) {
return false;
}
const urlString = hasScheme ? value : https://${value};
const url = new URL(urlString);
return url.protocol === "http:" || url.protocol === "https:";
} catch {
return false;
}
}

This keeps your fix for deep subdomains while still rejecting bad schemes upfront.

Skeleton loader commits

The two skeleton loader commits (a572e63, 144c499) are for issue #271, which is a separate feature from the URL validation fix (#270). It would be better to move those into their own PR so each PR has a single purpose. Also, the second commit just fixes an import from the first one, so those could be squashed together.

Pls fix and lmk
