Centered Content

<loomi-centered-content> — vertically and horizontally centers its content. Great for sign-in screens, empty pages and hero sections.

npm install @loomidev/centered-content lit

import "@loomidev/centered-content";

Basic Usage

Welcome back

Sign in to continue.

<loomi-centered-content>
  <h1>Welcome back</h1>
  <p>Sign in to continue.</p>
</loomi-centered-content>

Custom Dimensions

min-height controls how tall the centering area is; max-width caps the width of the content inside it. Both accept any CSS length.

Welcome back

<loomi-centered-content min-height="100vh" max-width="20rem">
  <h1>Welcome back</h1>
</loomi-centered-content>

Practical Example: Sign-In Screen

Sign in

Sign in

<loomi-centered-content min-height="100vh" max-width="24rem">
  <loomi-card>
    <h1 style="margin:0 0 1rem">Sign in</h1>
    <loomi-input type="email" label="Email"></loomi-input>
    <loomi-input type="password" label="Password"></loomi-input>
    <loomi-button block>Sign in</loomi-button>
  </loomi-card>
</loomi-centered-content>

Practical Example: Empty Page

Pair it with <loomi-empty-state> for a centered “nothing here yet” screen.

<loomi-centered-content min-height="70vh" max-width="28rem">
  <loomi-empty-state
    heading="No projects yet"
    message="Create your first project to get started."
    button-label="New project"
  ></loomi-empty-state>
</loomi-centered-content>

Framework integration

<loomi-centered-content> is a standard custom element, so the browser can use it in plain HTML, Blade, React, Vue, Angular, Svelte, Astro, and most other frameworks. The important beginner rule is: install the package, import it once before the tag is rendered, then write the Loomi tag in your template.

Where to run commands

Run install commands from the app where you want to use this component. That means the folder that contains that app’s package.json. Do not run these install commands from packages/centered-content unless you are editing LoomiUI itself.

cd /path/to/your-app
npm install @loomidev/centered-content lit

If you are contributing to LoomiUI itself, first move to the top-level components folder. That is where the main package.json for all packages lives, and pnpm --filter ... commands should be run from there:

cd /path/to/your-copy-of-loomiui/components
pnpm --filter @loomidev/centered-content build
pnpm --filter @loomidev/centered-content typecheck

Choose your framework

Use the CDN version for prototypes, documentation pages, or a quick reproduction. The import map tells the browser where to find Lit, which Loomi components use internally.

<script type="importmap">
  { "imports": { "lit": "https://esm.sh/lit@3.3.3", "lit/": "https://esm.sh/lit@3.3.3/" } }
</script>
<script type="module" src="https://esm.sh/@loomidev/centered-content"></script>

<loomi-centered-content min-height="240px" max-width="32rem">
  <loomi-empty-state heading="Nothing here yet" message="Create your first record to get started."></loomi-empty-state>
</loomi-centered-content>

In Vite, Webpack, Parcel, Rollup, or a framework build pipeline, install the package and import it once in your main app JavaScript file. After that, you can use the Loomi tag anywhere in your app.

import "@loomidev/centered-content";

Run the install command from your Laravel project root, then import the component in resources/js/app.js. If your project uses Laravel Vite, npm run dev and npm run build should also be run from the Laravel project root.

cd /path/to/your-laravel-app
npm install @loomidev/centered-content lit
npm run dev

resources/js/app.js

import "@loomidev/centered-content";

<loomi-centered-content min-height="240px" max-width="32rem">
  <loomi-empty-state heading="Nothing here yet" message="Create your first record to get started."></loomi-empty-state>
</loomi-centered-content>

React can render Loomi tags directly. If you are on React 18, or if you need to pass arrays, objects, or functions, use a ref and assign those values after the component mounts.

import "@loomidev/centered-content";

export function LoomiExample() {
  return (
    <loomi-centered-content min-height="240px" max-width="32rem">
      <loomi-empty-state heading="Nothing here yet" message="Create your first record to get started."></loomi-empty-state>
    </loomi-centered-content>
  );
}

If TypeScript does not recognize the Loomi tag in JSX, add it to your app’s JSX type declarations.

Import the package in the component that uses it, or once in your main Vue file. Vue templates can use Loomi tags directly. For arrays, objects, or functions, pass the value as a JavaScript property instead of as plain text.

<script setup>
import "@loomidev/centered-content";
</script>

<template>
  <loomi-centered-content min-height="240px" max-width="32rem">
    <loomi-empty-state heading="Nothing here yet" message="Create your first record to get started."></loomi-empty-state>
  </loomi-centered-content>
</template>

If Vue warns that the tag is an unknown component, configure compilerOptions.isCustomElement for tags that start with loomi- in your Vite or Vue config.

Import the package once and tell Angular to allow custom HTML tags with CUSTOM_ELEMENTS_SCHEMA. For NgModule apps, add the schema to the module instead of the standalone component.

app.component.ts

import { CUSTOM_ELEMENTS_SCHEMA, Component } from "@angular/core";
import "@loomidev/centered-content";

@Component({
  selector: "app-root",
  standalone: true,
  schemas: [CUSTOM_ELEMENTS_SCHEMA],
  template: `
    <loomi-centered-content min-height="240px" max-width="32rem">
      <loomi-empty-state heading="Nothing here yet" message="Create your first record to get started."></loomi-empty-state>
    </loomi-centered-content>
  `,
})
export class AppComponent {}

Svelte can import the package inside a component script. Astro can import it in the frontmatter of the page or layout where the tag appears.

<script>
  import "@loomidev/centered-content";
</script>

<loomi-centered-content min-height="240px" max-width="32rem">
  <loomi-empty-state heading="Nothing here yet" message="Create your first record to get started."></loomi-empty-state>
</loomi-centered-content>

---
import "@loomidev/centered-content";
---

<loomi-centered-content min-height="240px" max-width="32rem">
  <loomi-empty-state heading="Nothing here yet" message="Create your first record to get started."></loomi-empty-state>
</loomi-centered-content>

Server-side rendering notes

Frameworks such as Next.js, Nuxt, SvelteKit, and Astro sometimes render HTML on the server before browser-only code runs. If your framework complains, move the Loomi import to client-side code. In Next.js, that usually means a component with "use client"; in Nuxt, it often means a .client.ts plugin.
