Error1: Centered 404 Message

A minimal 404 page built around a single centered column: an oversized error code, the heading, a short explanation, a button row, and a divided footer of popular page links. Every string is a prop, so the same block covers 404, 403, and 500 screens.

Installation

Radix flavor

npx shadcn add "https://ui.beste.co/r/error1"

Base UI flavor

npx shadcn add "https://ui.beste.co/r-base/error1"

This installs the block to components/beste/block/error1.tsx, plus the button shadcn/ui primitive it uses for the call-to-action row.

Quick start

The installed file exports error1Demo alongside the block: the exact props behind the preview above. Spread it into Next.js's not-found.tsx to get a working error page in one line.

import { Error1, error1Demo } from "@/components/beste/block/error1";

export default function NotFound() {
  return <Error1 {...error1Demo} />;
}

Then replace the demo with your own props. Written out, a trimmed setup looks like this:

import { House } from "lucide-react";
import { Error1 } from "@/components/beste/block/error1";

export default function NotFound() {
  return (
    <Error1
      code="404"
      heading="This page could not be found"
      description="The page you are looking for was moved, renamed, or never existed."
      buttons={[
        { label: "Back to home", href: "/", icon: House },
        { label: "Contact support", href: "/support", variant: "outline" },
      ]}
      linksLabel="Popular pages"
      links={[
        { label: "Documentation", href: "/docs" },
        { label: "Pricing", href: "/pricing" },
      ]}
    />
  );
}

Props

type ActionButton = {
  label: string;
  href: string;
  variant?: "default" | "outline" | "secondary" | "ghost";
  icon?: LucideIcon;
};

type QuickLink = {
  label: string;
  href: string;
};

Behavior notes

• The whole block is static markup with no client state, so it renders fully on the server and works with JavaScript disabled.
• Each section is independently optional: the code, heading, description, button row, and the entire link footer only render when their prop is set (or, for arrays, non-empty), so a bare heading plus buttons is a valid configuration.
• Button icons come from the button data itself (icon is a Lucide component reference), so the icon side is fixed to the left of the label and there is no separate external-link flag.
• Quick links animate their trailing arrow 2px to the right on hover through the named group/error1 group, so nesting this block inside another hover group will not trigger it.
