@binz/visor v0.3.1
Visor
Full-coverage <head> gear for your Astro app.
Visor automatically generates the necessary HTML tags for global metadata, including:
<meta>tags for charset, viewport, theme color, and description.<link>tags for favicon and canonical URL.<meta>tags for OpenGraph and Twitter tags, including title, description, image, and more.<meta>tag for the generator (Astro version).
You can customize the values of these tags by passing the appropriate props to the component.

// src/layouts/default.astro
---
import {Visor} from '@binz/visor';
import logoSvgSrc from '../images/Logo.svg';
interface Props {
title: string;
}
const { title: pageTitle } = Astro.props;
const canonicalUrl = Astro.url;
---
<!doctype html>

twitterHandle: "@joe_blogs"
}}
canonicalURL={canonicalUrl}
description="Built with visor"

</html>Site Favicon Generation
Visor simplifies dynamic favicon generation with a pre-configured favicon.ico file.
Create a new API route at pages/favicon.ico to generate the favicon:
// pages/favicon.ico
import path from "node:path";
import type {APIRoute} from "astro";
import Favicon from "@binz/visor/favicon";
const faviconSrc = path.resolve("src/images/Logo.svg");
export const GET: APIRoute = Favicon({faviconSrc});PWA Support
Visor also supports Progressive Web App (PWA) features.
In addition to generating the necessary tags for PWA support, Visor can also be used to generate a manifest.json file for PWA support using Astro’s Static File Endpoints feature.
Add the pwa prop to the component in your Astro layout:
<Head
title="Example Site"
{'...'}
+ pwa
/>Finally create a new API route to generate the manifest.json file:
// pages/manifest.json.ts
import type {APIRoute} from "astro";
import Manifest from "@binz/visor/manifest";
import favicon from "./../images/Logo.svg";
const faviconPngSizes = [192, 512];
export const GET: APIRoute = Manifest({
name: "Example Site",
background_color: "#FFFFFF",
description: "An example site",
display: "standalone",
favicon: {
src: favicon,
faviconSizes: faviconPngSizes,
},
id: "example-com",
short_name: "Example",
start_url: "/",
theme_color: "#B9FF66",
});Example
